Why buy insurance?
"Because people are Risk Averse. Suppose that you own an asset worth $10,000 to you.  Suppose that each year, the asset has 1% chance of being stolen (or completely broken).  The expected value is 99% x 10,000 + 1% x $0 = $9,900. This is the average outcome if you do not buy insurance.  Now consider two mutually exclusive outcomes: 99% chance of keeping $10,000 and 1% chance of losing everything (expected value: $9,900)  100% chance of keeping $9,900 (expected value: $9,900)  Everyone would choose option 2, even though the expected values are the same.  Option 2 is an insurance that cost $100 (Actuarially fair, aka the odds are fair).  Now suppose the insurance costs $150 instead of $100 (despite that the bad probability is still 1%). You are faced with  99% chance of keeping $10,000 and 1% chance of losing everything (expected value: $9,900)  100% chance of keeping $9,850 (expected value: $9,850)  Some people would still choose option 2, even though the expected value is actually lower.  The $50 is called Risk Premium, which people are willing to pay in order to avoid uncertainty. The odds are unfair, but the Risk Premium has its value.  That being said, competition between insurance companies would drive down the premium until the insurance is close to actuarially fair, but they have cost to cover (sales, administration, etc), making the odds ""unfair""." "Discussions around expected values and risk premiums are very useful, but there's another thing to consider: cash flow. Some individuals have high value assets that are vital to them, such as  transportation or housing.  The cost of replacing these assets is prohibitive to them: their cashflow means that their rate of saving is too low to accrue a fund large enough to cover the asset's loss. However, their cashflow is such that they can afford insurance. While it may be true that, over time, they would be ""better off"" saving that money in an asset replacement fund, until that fund reaches a certain level, they are unprotected. Thus, it's not just about being risk averse; there are some very pragmatic reasons why individuals with low disposable income might elect to pay for insurance when they would be financially better off without it." As someone who has worked for both an insurance carrier and an insurance agent, the reason people buy insurance is two fold: to spread risk out, and to get the benefits (when applicable) of approaching risk as a group. What you are really doing when you buy insurance is you are buying in to a large group of people who are sharing risk.  You put money in that will help people when they take a loss, and in exchange get a promise of having your losses covered.  There is an administrative fee taken by the company that runs the group in order to cover their costs of doing business and their profits that they get for running the group well (or losses they take if they run it poorly.) Some insurances are for profit, some are non-profit; all work on the principle of spreading risk around though and taking risk as a larger group. So let's take a closer look at each of the advantages you get from participating in insurance.  The biggest and most obvious is the protection from catastrophic loss.  Yes, you could self-insure with a group size of one, by saving your money and having no overhead (other than your time and the time value of your money) but that has a cost in itself and also doesn't cover you against risk up front if you aren't already independently wealthy.  A run of bad luck could wipe you out entirely since you don't have a large group to spread the risk around.  The same thing can still happen to insurance companies as well when the group as a whole takes major losses, but it's less likely to occur because there are more rare things that have to go wrong.  You pay an administrative overhead for the group to be run for you, but you have less exposure to your own risks in exchange for a small premium. Another significant but less visible advantage is the benefit of being part of a large group.  Insurance companies represent a large group of people and lots of business, so they can get better rates on dealing with recovering from losses.  They can negotiate for better health care rates or better repair rates or cheaper replacement parts.  This can potentially save more than the administrative overhead and profit that they take off the top, even when compared to self-insuring. There is an element of gambling to it, but there are also very real financial benefits to having predictable costs.  The value of that predictability (and the lesser need for liquid assets) is what makes insurance worth it for many people.  The value of this group benefit does decrease a lot as the value of the insurance coverage (the amount it pays out) decreases.  Insurance for minor losses has a much smaller impact on liquidity and is much easier to self insure.  Cheaper items that have insurance also tend to be high risk items, so the costs tend to be very high relative to the amount of protection.  If you are financially able, it may make more sense to self-insure in these cases, particularly if you tend to be more cautious.  It may make sense for those who are more prone to accidents with their devices to buy insurance, but this selection bias also drives the cost up further.  Generally, the reason to buy insurance on something like a cellphone is because you expect you will break it.  You are going to end up paying for an entire additional phone over time anyway and most such policies stop paying out after the first replacement anyway. The reason why people buy the coverage anyway, even when it really isn't in their best interest is due to two factors: being risk averse, as base64 pointed out, and also being generally bad at dealing with large numbers.  On the risk averse side, they think of how much they are spending on the item (even if it is less compared to large items like cars or houses) and don't want to lose that.  On the bad at dealing with large numbers side, they don't think about the overall cost of the coverage and don't read the fine print as to what they are actually getting coverage for.  (This is the same reason that you always see prices one cent under the dollar.)   People often don't really subconsciously get that they are paying more even if they would be able to eat the loss, so they pay what feels like a small amount to offset a large risk.  The risk of loss is a higher fear than the known small, easy payment that keeps the risk away and the overall value proposition isn't even considered. Regarding auto insurance, you have to look at the different parts. In the United Sates most states do require a level of specific coverage for all drivers. That is to make sure that if you are at fault there is money available to pay the victims. That payment may be for damage to their car or other property, but it also covers medical costs. Many policies also cover you if the other driver doesn't have insurance. The policy that covers the loss of the vehicle is required if you have a loan or are leasing the car. Somebody else owns it while there is a loan, so they can and do require you to pay to protect the vehicle.  If there i no loan you don't have to have that portion of a policy. Other parts such as towing, roadside assistance, and rental cars replacement may be required by the insurance standards for your state, or might be almost impossible to drop because all insurance companies include it to stay competitive with their competition.  Dropping the non-required parts of the coverage is acceptable when you don't have a loan. Some people do drop it to save money. But that does mean you are self insuring. If you can afford to self insure a new car, great. The interesting thing is that some people have more than enough assets to self inure the non-required part of auto insurance. But then they realize that they do need to up their umbrella liability insurance. This is to protect them from somebody deciding that their resources make them a tempting target when they are involved in a collision. One reason is that insurance gives you tranquility.  Without insurance, you live with the uncertainty of not knowing if/when disaster is going to strike. Insurance allows you to trade this uncertainty for regular monthly/yearly payments. "There's an old saying among commodities producers... If it's likely to happen, but won't kill you, you hedge (save/""self-insure"", options, futures). If it's not likely to happen, but would kill you, you insure.  Hedging and insuring are both about managing risk. If you feel there is no risk at all, you don't need to do either. But feeling that you have no risk at all is somewhat naive." (Disclosure - I am a real estate agent, involved with houses to buy/sell, but much activity in rentals) I got a call from a man and his wife looking for an apartment. He introduced itself, described what they were looking for, and then suggested I google his name. He said I'd find that a few weeks back, his house burned to the ground and he had no insurance. He didn't have enough savings to rebuild, and besides needing an apartment, had a building lot to sell.  Insurance against theft may not be at the top of your list. Don't keep any cash, and keep your possessions to a minimum. But a house needs insurance for a bank to give you a mortgage. Once paid off, you have no legal obligation, but are playing a dangerous game. You are right, it's an odds game. If the cost of insurance is .5% the house value and the chance of it burning down is 1 in 300 (I made this up) you are simply betting it won't be yours that burns down.  Given that for most people, a paid off house is their largest asset, more value that all other savings combined, it's a risk most would prefer not to take.  Life insurance is a different matter. A person with no dependents has no need for insurance. For those who are married (or have a loved one), or for parents, insurance is intended to help survivors bridge the gap for that lost income. The 10-20 times income value for insurance is just a recommendation, whose need fades away as one approaches independence. I don't believe in insurance as an investment vehicle, so this answer is talking strictly term. This is just an addition to base64's answer.  In order to maximize your overall wealth (and wellbeing) in a long run, it is not enough to look only at the expected value (EV). In his example of always keeping $9850 or having $10000 99% of the time, EV in the second case is greater ($9900 > $9850) and if you are Bill Gates than you should not take an insurance in this case. But if your wealth is a lot less than that you should take an insurance. Take a look at Kelly criterion and utility functions. If I offer you to take 100 million dollars (no strings attached) or to take a risk to get 200 million dollars 60% of the time (and $0 40% of the time), would you take that risk? You shouldn't but Bill Gates should take that risk because that would be a very good investment for him. Utility functions can help you choose if you want an insurance or not. Maybe you want to insure your house because the value of the house is a large percentage of your wealth but on the other hand you don't need to insure your car if it is very easy for you to afford another one (but not easy to afford another house). Lets calculate what your wealth should be in order not to take this $150 insurance on a $10000 item. If you pay $150 for an insurance you have guaranteed $9850. But choosing not to take an insurance is the same as betting $9850 in order to gain $150 99% of the time. By using Kelly criterion formula fraction of the wealth needed to make this bet is: [p*(b+1)-1]/b = [0.99*(150/9850+1) -1]/ (150/9850) = 1/3.  That means that if your wealth greater than $29950 you don't need an insurance. But if you want to be sure it is advised to use fractional Kelly betting (for example you could multiply fraction by 1/2) and in that case if your wealth is more than $59900 you don't need an insurance for this item. "You don't mention what kind of insurance you're talking about, but I'll just address one angle on the question. For some kinds of insurance, such as health insurance (in the US), auto insurance, and homeowner's insurance, you may be insuring against an event that you would not be able to pay for without the insurance.  For instance, if you are at fault in a car accident and injure someone, they could sue you for $100,000.  A lot of people don't have $100,000.  So it's not even a matter of ""I'll take the risk of having to pay it when the time comes""; if the time comes, you could lose virtually everything you own and still have to pay more from future earnings.  You're not just paying $X to offset a potential loss of $Y; you're paying $X to offset a potential derailment of your entire life.  It is plausible that you could assign a reasonable monetary value to that potential ""cost"" that would mean you actually come out ahead in the insurance equation. It is with smaller expenses (such as insuring a new cellphone against breakage) that insurance becomes harder to justify.  When the potential nonfinancial ""collateral damage"" of a bad event are less, you must justify the insurance expenses on the financial consequences only, which, as you say, is often difficult." It's not a betting game, insurance policy is not akin to a casino bet. While the odds are probably low, the damage of an event may be devastating. Insurance allows mitigating that potential devastating damage, if it occurs. Most people buy insurance because it is legally required to own a car or to have a mortgage. People want to own homes and to have personal transportation enough that they are willing to pay for required insurance costs. There are a lot of great explanations here as to why insurance is important and I don't want to detract from those at all. However, if we're being honest, most people are not sophisticated enough to measure and hedge their various financial risks. They just want to own an home and to drive a car. The odds could very well be in your favor, even when the insurance company expects profit. What matters to you is not the expected amount of money you'll have, but the expected amount of utility you'll get from it: getting enough money to buy food to eat is much more important than getting enough money to be able to buy that fiction book too. The more money you have, the less a dollar is worth to you: consequently, if you have enough money, it's worth spending some to prevent yourself from getting into a situation where you don't have enough money. "People's value of money is not always linear.  Consider an individual with $1000 in the bank.  I'm going to look at amounts of debt by orders of magnitude: Now its pretty easy to see a order of magnitude increase in impact from $100 to $1000, and it becomes slightly worse for the $10,000 case due to debt.  However, one more order of magnitude, going to $100,000, and suddenly it becomes hard to argue that there's a mere ""order of magnitude more hurt"" than the $10,000 case.  From the cases I've read, those sorts of situations can be far far worse than the monetary cost could convey. Insurance companies are in a good position to absorb $100,000 of debt if something happens, far better position than the individual.  They rely on the central limit theorem: in general, they don't have to pay out all at once. The insurance companies have their limits too.  When hurricane Katrina came through, the insurance companies had a tremendously difficult time dealing with so many claims all at once.  Just like the individuals, they found a sudden change in how much value they had to put on their monetary debts!" For big values the loss becomes negligible. Say you have a 10% chance to get 10 million $/€/Whatever, expected value 1m. You sell that chance for 990k, which loses you 10k of expected income. Why would you throw away 10k? Because in the face of getting almost 1m the 10k are insignificant, 1m and 990k will make you roughly equally rich. Also the richness increase from 1m to 10m is less than 10x since 1m gives you maybe 90% of the freedom that 10m does (depending on how well you can make 10m work for you, most people will just let it rot in the bank). Another way to look at it is to look at bankruptcy risk. Say I have 10k in the bank, which is nice. Those 10k cannot pay for a new house or 2 cars (mine and the one I hit), so I have a small risk of significant loss. If I buy an insurance I reduce my chance of going bankrupt from maybe 0.001% to 0% for a fairly small price. Usually you can buy insurance fairly cheap if you raise your deductible to maybe 5k (both for the house and the car) so that you shoulder the risk you can (shouldering risk = gaining money) and paying an insurance to shoulder the rest for you. That way you minimize the cost to remove the risk of bankruptcy. It makes sense to shoulder as much risk as you can (unless a fixed fee of the insurance makes in unfeasible) before paying others to do it for you so you can optimize your income while removing fatal risks. There are several insurance products that I buy for legal reasons: Both of these protect me from lawsuits and fines. Many people buy similar products to protect their business operations. (e.g. medical malpractice insurance) There are some insurance products I buy for tax planning and financial planning purposes: I have a large amount of savings available, so I have several tricks to reduce my insurance costs, and I have several products that I avoid. Several of these reasons are mentioned in other answers, but I thought I would collect them into a single answer to demonstrate that there are reasons other than the rational calculation of what the payout will be for the insurance products vs. the premium paid. If I gain access to a tax advantaged Health savings account, that is a bigger benefit to me than avoiding the premium, especially when my employer is paying the majority of the premium. Perhaps it makes no sense to buy insurance given sufficient savings (like the products I listed that make no sense for me given my finances) but not everyone can self-insure; it does require a certain level of wealth. There are many situations where injecting a certain amount of cash at the right time may reap rewards far in excess of the value of the cash injected. For example, if someone who needs a car to get to work gets in a wreck and that person does not have ready money to make it driveable may have no choice but to secure very expensive financing.  Receipt of $1000 in ready money to repair the car may thus save the person from having to take out a loan that would cost $1200 or more to repay. While the insurance business has sufficient overhead that it is unlikely that insurance would generally have a positive net expectation even considering such factors, it is at least theoretically possible that insurance could have a positive expected value for both the insurer and the insured (and in some cases it may have positive expected values for both parties in practice as well). Apart from legal requirements to have insurance, e.g. 3rd party car that other answers have covered well. We can think of all insurance as protecting our “usable” income, as we can use cashflow to pay the costs of a loan to replace whatever we decided not to insure.    So for example, if I don’t insure my house contents, I can replace them on my credit card if needed. Therefore we are paying for insurance out of our income, so as to protect our income, knowing that the cost of the protection is on average more than the benefit we get from it. But we all know that having an income of $50K is less than double the value of having an income of $25K.   (E.g. being able to eat and remain warm is more important to us then being able to go on anther holiday.)  This is way when someone has a higher income; it requires more money to effect their actions. Loss aversion is another factor; we are people not logistical machines. "The fundamental flaw here is conflating net worth with utility, at least failing to recognize that there's a nonlinear relationship between the two.  In the extreme example imagine taking a bet that will either make you twice as rich or completely broke. Your expected return is zero, but it would be pretty dumb to take it since being flat broke could ruin your life while being twice as rich may only improve it marginally. In more realistic cases most of your income is tied up in fixed costs, which magnifies relatively small perturbations to your net worth. Losing something essential (like your house or car), even if it's only 20% of your net worth, renders you effectively broke until you scrape together enough cash to get another one. That situation robs you of much more utility than you'd gain from a 20% increase in net worth. In either case, avoiding the risk is completely rational as long as you believe in nonlinear utility as a function of net worth, it's not just an issue of humans being ""risk averse""." "Lots of people make poor decisions in crises.  Some panic, and don't make any decision at all. Insurance for affordable things can provide emotional security:  If something goes wrong, the purchaser will not have to make a painful financial decision in a crisis.  Many people do not want to have the burden of arguing about money, or having to spend precious cash, or borrow money, or raid savings accounts, just at the time they are already reeling from another loss.  Having insurance ""just take care of it"" can save them an emotional double-whammy.   Several kinds of insurance fill this perceived need:" "Insurance is bought for peace of mind and to divert disaster.   Diverting disaster is a good/great thing.  If your house burned down, if someone hit your car, or some other devastating event (think medical) happened that required a more allocation than you could afford the series of issues may snowball and cause you to lose a far greater amount of money than the initial incident.  This could be in the form of losing work time, losing a job, having to buy transportation quickly paying a premium, having to incur high rate debt and so on.   For the middle income and lower classes medical, house, and medical insurance certainly falls into these categories.  Also why a lot of states have buyout options on auto insurance (some will let you drive without insurance by proving bonding up to 250K.   Now the other insurance as I have alluded to is for peace of mind mainly.  This is your laptop insurance, vacation insurance and so on.  The premise of these insurances is that no matter what happens you can get back to ""even"" by paying just a little extra.   However what other answers have failed to clarify is the idea of insurance.  It is an agreement that you will pay a company money right now.  And then if a certain set of events happen, you follow their guidelines, they are still in business, they still have the same protocols, and so on that you will get some benefit when something ""disadvantageous"" happens to you.  We buy insurance because we think we can snap our fingers and life will be back to normal.  For bigger things like medical, home, and auto there are more regulations but I could get 1000 comments on people getting screwed over by their insurance companies.  For smaller things, almost all insurance is outsourced to a 3rd party not affiliated legally with a business.  Therefore if the costs are too high they can simply go under, and if the costs are low they continue helping the consumer (that doesn't need help).   So we buy insurance divert catastrophe or because we have fallen for the insurance sales pitch.  And an easy way to get around the sales pitch - as the person selling you the insurance if you can have their name and info and they will be personally liable if the insurance company fails their end of the bargain." I keep it simple. Here's what I learned when I took Personal Financial Planning: Insurance is for low likelihood, high-impact events. "The definition of insurance is the transfer of risk. Thus, you're paying for transferring of a risk (of an item/property) to the insurer (carrier), so that they bear the financial burden of a loss/accident and not you. You could always self-insure, but a lot of times, insurance is cheaper, since due to the ""Law of Large Numbers"" the insurer can just charge a premium that is small percentage in comparison to the cost of self-insuring." "First of all, insurance never covers the cost of the item, it is almost always a partial payout at best. For example, a typical house in the Northeast US where I live that costs $300,000 will have the actual house valued at maybe $100,00 and rest of the value will be in the land. Therefore, the insured value will typically be $100,000. The only problem is that to actually rebuild the house might easily cost $250,000. So, your idea that some kinds of insurance allows the beneficiary to recoup their loss is usually never true. As you say, from an actuarial point of view insurance is a sheer waste of money. For example, a typical house has maybe a 0.5% chance of burning down every year. In other words out of 2000 houses, maybe 1 will burn down every year. So, lets say you got $100,000 of insurance on your house. Then the value of that policy would be $100,000 / 2000 = $50 per year. An insurance company will charge around $700 per year for the policy. That means you are basically flushing $650 down the toilet every year to maintain that policy. The reason why they do this is what blankip says above, they are buying ""peace of mind"", a psychological product. In other they imagine they are somehow safe. So, even though they are losing money, paying it makes them feel as though they are not losing money. It's delusional, but then again most people have a lot of delusions of which insurance is just one of many."
Think of it. How does an insurance company make money? Well essentially, it tries to have more knowledge about risk than those insuring themselves. It also attempts to manage its investments better. Well to this requires a lot of knowledge of statistics and this is primarily what you will be doing over your career. One friend got into it because he liked to gamble and win (he lost about $2k as a young teenager in Hong Kong). He spent a lot of time studying probability and statistics and then became fascinated by it. So fascinated that he became a full actuary, which means a long time studying. He was willing to put the time in. Some countries don't have robust life insurance markets.  Some countries have horrible travel fatality statistics.  Some countries don't have very good liability law enforcement.   Is $2 on top of a train ticket in the US to send your family a $20,000 payment if you die on the train worth it, probably not.  The fatality rate is pretty low here, lots of people have their own life insurance, and the US justice system carries a big liability stick. If you're moving around on trains a lot in other countries where the fatality rate is much higher, you can't buy life insurance on your own, and the legal system doesn't punish negligent operators it might be meaningful, especially for frequent travelers who have dependents. Is buying this coverage a reasonable and cost effective way to insure a person's life, no, clearly not.  You're buying a policy to insure your life against being mauled by tiger in New York on a Tuesday, when you've never seen a tiger and don't live in New York.  Obviously, if you want life insurance you would not buy coverage this narrow. Personally, I think this is really akin to an impulse buy candy bar at a checkout line of a market.  They're dangling this in front of you for an amount of money that's insignificant because some people will pick it up without thinking about it.  They're tickling your fear of death just enough to get a dollar from you, but not enough to keep you off the train.  And obviously the math works out for the insurer or it would not be offered. Separately, regarding probability, it's not about an incident occurring in a train, it's an incident occurring in this particular train on this particular day/time.  If there's a 1 in 10,000 chance of dying on a train in a year the chance of dying on a particular train on a particular day is likely to be one in billions or more.  This really isn't about whether or not this coverage is valuable given the risk, it's about whether or not they can get you to impulsively spend a dollar. This answer should be taken as a counterpoint to Thevin S's excellent answer. I have comprehensive insurance on my vehicle. That is, if I crashed it and wrote it off, my insurance would cover the replacement costs. Now, if this happened, I would be able to deal with the replacement costs myself, even without insurance. It would not significantly impact my lifestyle and would not put my emergency funds at risk, though obviously I wouldn't be happy about this. As the insurance company is planning on making money off of me, it's clearly not in my financial best interests to carry this insurance. Statistically speaking, it's a cost to me, and a profit for the insurance company. So why do I do it? Because I find it easy to pay a small amount of money every month for the peace of mind that, if I crash my car, I will not have to cover the large expense. I am (perhaps irrationally) risk averse. I'm happier paying a small amount of money in exchange for a guarantee that I will not have to pay a large amount of money. I mitigate a potentially larger cost, albeit with low likelihood, for the certainty of a smaller cost (my monthly insurance payments). This is separate from the mandatory PL/PD (public liability, public damage) insurance that I am required to cover. That insurance fits into Thevin's definition of a devastating event. This is going to be a philosophical answer, but here it goes.  What is the purpose of an insurance? In my perspective, insurance is a way to protect yourself from risks in life you can not afford to take. Following this principle, most of the people do not have enough money to fix a Ferrari, or pay the medical expenses of a third party--so insurance against liabilities makes financial sense, but many can afford buying an equivalent car as they are insuring.  If you have enough money to buy an equivalent car, you are paying for a risk you can take yourself. Then, instead of paying the comprehensive fee which is used to pay the different accidents, the company's administrative fees and the shareholder profits; I would save your money in a separate account and use it as a self-insurance. That is at least what I do.  I even put other insurances and extended warranties, which respective risks I have decided to absorve; that way I diversify my fund. "Many answers here have given what look to be useful perspectives on your question.  I want to point out an interesting technical issue. If an employer contracts with an insurer, it agrees to cover all employees (or all that fill some pre-specified definition and no one else), and to offer only a limited range of options. If you buy insurance directly, you obviously have a huge range of choices, including the (technically illegal) one of no insurance at all. Your first thought is probably, ""Hey, that's great! More options, more chances to pick the plan that's right for me."" Sorry, no.  Yes, you have more options, but so does everyone else. If you are working for some large company, you get insurance, period. If you suspect you have an expensive health condition, you cannot buy more insurance; if you believe yourself to be healthy as a horse, you cannot get skimpier insurance and pocket the difference.  Healthy people and sick people are all in the same predictable pool. If you buy insurance freely, the insurer knows that the sicker you are, the more likely you are buy insurance, a phenomenon called adverse selection.  As a result, the premiums (fees) a person buying his own insurance pays are much higher, because most of his fellow policy-holders are sickly -- even if he himself is just risk-averse. On the other hand, if you are risk-neutral, if you can survive a $10,000 bill if it happens to arise, you can save big by finding the skimpiest imaginable insurance, where all your fellow policy-holders will be hale and healthy people like yourself." "Insurance is a financial product to control risk. The fact that a loss would not be catastrophic simply makes the decision to carry insurance less critical. It is perfectly reasonable to be ""self-insured"" in this case. This is assuming we are discussing replacement of your property vs liability (which you have made clear). Like many other products one buys, a fine reason to purchase insurance is simply because one wants to. Just because you can absorb the loss, does not mean that you want to take on the full risk. I would be careful of your analysis here: Insurance companies on average make money by selling insurance, which means you lose money on average by dealing with them Insurance companies make money based on the cumulative probability that they will have to pay on multiple policies. To make money, they analyze the risk that in a given period they will only pay on a portion of their hundreds of thousands or millions of policies. This is a different analysis than the probability that you will have a loss on your specific asset.  Your risk of a loss is not equivalent to their risk of loss here. The argument that they only 'win' if you individually 'lose' is not a good one." "There are 2 maxims that help make sense of insurance: Following those 2 rules, ""normal"" insurance makes sense. Can't afford to replace your car? insure it. Can afford to lose your TV? Don't insure it. People with a net worth in the low millions have very similar insurance needs to the middle class. For example, they might be able to afford a new car when they total it, but they probably can't afford to pay for the long term care of the person they accidentally ran over. Similarly, they probably need to insure their million dollar house, just like average people insure more affordable housing.  ""Very wealthy"" people still have the same basic choices, but for different assets.  If you are a billionaire, then you might not bother to insure your $30k childhood home or your fleet vehicles, but you probably would insure your $250m mansion, your $100m yacht and your more pricey collectible cars.  It's also worth noting that ""very wealthy"" people are at much higher risk of being sued for negligence or personal injury. As such, they are more likely to purchase personal liability or umbrella insurance coverage to protect against such risks. Multi-million-dollar personal injury suits would never be filed against a poorer person simply because they couldn't afford to pay even the plaintiff's lawyer fees when they lost the court case. Insurance also makes sense when the insurance company is likely to (grossly) underestimate the risk they are taking.  For example, if I am a really bad driver, but i have a clean record thanks to my army of lawyers, then insurance might actually be a good deal for me even on average. To take the ""very wealthy"" stereotypes to the extreme, perhaps my eccentric billionaire neighbor and I are in an escalating feud which I think will result in my butler ""accidentally"" running his car into my neighbor's precious 1961 Ferrari." Another reason to buy insurance, though not applicable in this case, is that the insurance company is a big buyer of services and will be able to buy any services covered under the policy much more cheaply than you will. So they can charge you less than your expected payouts if you were uninsured and still make a profit. This particularly applies to things like medical and veterinary insurance. "i dont know how they would buy *term* policies though, i suppose there is an actuarial value to the policy (ie. you might die during the policy term).  A lot of these polices are ""10 year term"" or something like that, so the actuarial value might be significant. (a lot of people get these who cant get whole life or cant afford to get it, with the health problems they now have).  Something tells me these transactions are not very advantageous to the insured (especially since i've seen them heavily advertised on channels my mom tends to watch)" There is no benefit in life insurance as such (ie, death insurance.) There is a great deal of value in other types though: total and permanent disability insurance, trauma insurance (a lump sum for a major medical event), and income protection insurance (cover against a temporary but disabling medical condition).  If you don't have that, you should get it right now. This is about the most important insurance you can carry.  Being unable to work for the rest of your life has a far larger impact than having, say, your car stolen. ...  If, later on, you acquire dependents, and you feel you ought to have life insurance, then you will have a relationship with a life insurance company, and maybe they will let you upgrade from income/TPD to income/TPD/life without too much fuss or requalification.  Some do; whether yours would I don't know.  But at least you have a toe in the door with them, in a way that is infinitely more immediately useful than getting life insurance that you don't actually need. "These policies are usually called dread disease policies or critical illness insurance, and they normally aren't a good deal. Furthermore, with the passage of the Affordable Care Act, such policies may become less common or disappear entirely. These policies aren't a great deal because of the effects of adverse selection and asymmetric information, two closely related concepts in the economics of insurance. When you purchase an insurance policy, the insurance company charges you a premium based on your average risk level or the average risk level of your risk pool, e.g. you and your fellow employees, if you get insurance through your employer. For health insurance, this average risk level is the average probability that you'll incur healthcare costs. The insurer's actuaries calculate this probability from numerous factors, like your age, sex, current health, socioeconomic status, etc. Asymmetric information exists when you know more about this probability than the insurance company does. For example, you may look like a relatively low-risk individual on paper, but little does the insurance company know, BASE jumping is one of your hobbies. Because you know about your hobby and the insurance company doesn't, you secretly know that your risk of incurring healthcare expenses is much higher than the insurance company expects. If the insurance company knew this, they would like to charge you a much higher premium, if they could. However, they can't, because a) they don't know about your hobby, and b) the premium may be decided for the entire group/risk pool, so they can't increase it simply because a few individuals in the group have higher risk levels. Adverse selection occurs when individuals with higher risk levels are more likely to buy insurance. You may decide that because of your dangerous hobby, you do want to take advantage of your employer's healthcare plan. Unfortunately for the insurance company, they can't adjust their price accordingly. Adverse selection is a major factor in insurance markets, so I didn't go into much detail here (too much detail is probably off-topic anyway). I can point you towards more resources on the topic if you're interested.  However, the situation is different when you purchase a dread disease policy.  By expressing interest in such a specific policy, e.g. a cancer insurance policy, you signal to the insurance company that you feel you have a higher risk of facing that disease. In your case, you're signaling to the insurance company that your family probably has a history of cancer or that you have habits that make you more susceptible to it, and your premiums will be higher to compensate the insurance company for bearing this additional risk. Since the insurance company already has a rough estimate of your chances of developing that illness, they may already know that you have a higher chance of facing it. However, when you express interest in a disease-specific policy, this signals the existence of asymmetric information (your family history or other habits), and the insurer assumes you know something they don't that elevates your risk level of that specific disease. Since these policies are optional policies often sold as riders to existing policies, the insurance company has more flexibility in pricing them. They can charge you a higher premium because you've signaled to the insurer that you have a significantly above-average risk of contracting a specific disease*. Also, the insurer can do a much better job of estimating the expected costs of insuring you since they need only focus on data surrounding one disease. The policy will be priced accordingly, i.e. in such a way that isn't necessarily beneficial to you. Furthermore, most dread disease policies aren't guaranteed renewable, which means that even if you are willing to keep paying the premiums, the insurance company doesn't have to keep insuring you. As your risk of developing the specific disease grows, e.g. with age, it may pass the point where insuring you is no longer an acceptable risk. The company expects you to develop the illness with the next few renewal cycles, so they decide not to renew your policy. The end result? The insurance company has the premiums you've paid previously, but you no longer have coverage for that illness, and ex post, you've suffered a net loss with no reduction of risk for the foreseeable future.  Dread disease policies are changing under the Affordable Care Act. According to healthcare.gov Starting in 2014, ... all new health insurance plans sold to individuals and small businesses, and plans purchased in the new Affordable Insurance Exchanges, must include a range of essential health benefits. The essential health benefits include quite a few areas of coverage; since this applies to policies offered on the state insurance exchanges and those offered outside of it, dread disease policies wouldn't seem to qualify. For more information, you can read the linked page on healthcare.gov or see Section 1302, subsection b), titled ""Essential Health Benefits Requirements"" in the law itself (p87). I imagine more details will be available on a state-by-state basis through 2014 and into 2015.  One legal source (see the discussion on p24) states that: whatever else the ACA does with excepted benefit policies, including specific disease and fixed dollar indemnity policies, it does explicitly provide that such policies do not count as minimum essential coverage for purposes of the ACA This seems pretty straightforward; a dread disease (or ""specific disease"" policy, as it's referred to in the article), won't count towards the minimum essential requirements. This may not be an issue for you, but for others, it's important to understand that you'll still need to pay the penalty if you only purchase one of these policies. The ACA spells this out in Section 5000(f) (see p316, which states that ""excepted benefit policies"" are excluded and defines them using the definition in the Public Health Service Act (PHSA). **The PSHA specifically includes ""Coverage only for a specified disease or illness"" in their definition of ""excepted benefit policies"" (see section 2791(b), paragraph 3A on p82, so it's probably a safe bet that such policies won't count towards the minimum. Also, as Rick pointed out in the comments, the Affordable Care Act also forbids lifetime limits on most insurance plans, so assuming you find an insurance policy with adequate coverage for the specific disease you're worried about, such a plan should cover the related expenses without a lifetime limit. Deductibles, annual limits, and other factors may complicate this somewhat.  In the section about lifetime limits (Sec. 2711, p2), the Affordable Care Act states that: A group health plan and a health insurance issuer offering group or individual health insurance coverage may not establish ... lifetime limits on the dollar value of benefits for any participant or beneficiary.  However, the law states in the next paragraph that the preceding statement should not be construed to prevent a group health plan or health insurance coverage from placing annual or lifetime per beneficiary limits on specific covered benefits that are not essential health benefits under section 1302(b) of the Patient Protection and Affordable Care Act, to the extent that such limits are otherwise permitted under Federal or State law The section also contains similarly vague caveats about annual limits, so the actual details and limits may vary once individual states finalize their policies. The law is intentionally vague because the vast majority of the law's implementation is left up to individual states. Furthermore, certain parts of the law specify actions involving the Secretary of Health and Human Services, so these may require further codification in the future too. You should still read the fine print of any insurance policy you buy and evaluate it as you would any contract (see the next section).  Since a dread disease policy probably isn't a good idea, you'll probably want to evaluate the healthcare plans offered by your employer or individual plans offered in your area (if your employer doesn't offer coverage). I've tried to include the basic points offered in these articles to give you or future visitors some idea of where to start. These points may change once the Affordable Care Act is implemented, so I'll try to keep them as general as possible.  Services - Above and beyond the minimum essential requirements, what services does the plan offer? Are these services a good match for you and/or your family, or do they add unnecessary cost to the premium with little or no benefit? For example, my health insurance plan offers basic dental coverage with a small co-pay, so I don't need a separate dental plan, even though my employer offers one.  Choice - What doctors, clinics, hospitals, etc. are preferred providers under your plan? Do you need a referral from your primary care doctor to see a specialist, or can you find one on your own? Are the preferred providers convenient for you? In my first year of college (about five years ago), my student health insurance only covered a few hospitals that were in the suburbs and somewhat difficult for me to reach. This is something to keep in mind, depending on where you live.  Costs - This is a major one, obviously. Deductibles, copays, maximum cost limits over a year or your lifetime, out-of-network costs, etc. are all variables to consider.  There are other factors, but since I don't have a family, other members of the site can provide more detailed information about what to look for in family policies.  In place of a dread disease policy, you're likely better off purchasing a comprehensive health insurance policy, perhaps a catastrophic coverage policy with a high deductible that will kick in once you've exhausted your standard insurance policy. However, this may be a moot point since the passage of the Affordable Care Act may significantly reduce the availability of such policies anyway." I've had many home loans, and all have been sold to a big bank.  They have certain rules about how much insurance you need to have, but I've never had one buy insurance on my behalf - they always send letters telling me I need to increase the insurance.  They do say that if I don't get enough insurance, they will do it for me, but this has never been necessary. Insurance is to mitigate risk you can't handle yourself.  (All insurance, not just car insurance.)  The expected value of the insurance will always cost more than the expected value of your loss, that's how the insurance company makes money.  But sometimes the known fixed cost is better for your ability to sleep at night than the unknown (though likely lower) variable cost. If you were suddenly hit with a bill the size of your car tomorrow, would you be ok?  If so, then you can handle the risk yourself and don't need insurance.  If not, then you need the insurance. The insurance company sells thousands of policies and it's much easier to predict the number out of 1000 people that will get in an accident tomorrow than the chance that you specifically will get in an accident tomorrow.  So they can manage the risk by making a small amount of money from 999/1000 people and buying the other guy a new car. As you have already good on your retirement kitty. Assuming you have a sufficient cash for difficult situations, explore the options of investing in Shares and Mutual Funds. As you are new to Stock Market, begin slowly by investing into Mutual Funds and ETF for precious metals. This will help you understand and give you confidence on markets and returns. Real estate is a good option, the down side being the hassle of getting rental and the illiquid nature of the investment. There are too many qualifying questions like martial status, dependent status, annual income, etc. Your answer is most likely in the Form Pub 970 you referenced: Adjustments to Qualified Education Expenses If you pay qualified education expenses with certain tax-free funds,   you cannot claim a deduction for those amounts If the grant is tax free, you can not claim deductions up to that amount. Even if you were able to expense all the educational expenses you list, I doubt you can exceed the grant disbursement disbursement amount. I'm not a tax professional, so take my advice for what it is worth.
