Should I finance a used car or pay cash?
There are several factors here. Firstly, there's opportunity cost, i.e. what you would get with the money elsewhere. If you have higher interest opportunities (investing, paying down debt) elsewhere, you could be paying that down instead. There's also domino effects: by reducing your liquid savings to or below the minimum, you can't move any of it into tax advantaged retirement accounts earning higher interest. Then there's the insurance costs. You are required to buy extra insurance to protect your lender. You should factor in the extra insurance you would buy vs the insurance required. Given that you can buy the car yourself, catastrophic insurance may not be necessary, or you may prefer a higher deductible than your lender will allow. If you're not sufficiently capitalized, you may need gap insurance to cover when your car depreciates faster than your loan is paid down. A 30 percent payment should be enough to not need it though. Finally, there's some value in having options. If you have the loan and the cash, you can likely pay it off without penalty. But it will be harder to get the loan if you don't finance it. Maybe you can take out a loan against the car later, but I haven't looked into the fees that might incur.  If it's any help, I'm in the last stretch of a 3 year car loan. At the time paying in cash wasn't an option, and having done it I recognize that it's more complicated than it seems. Unless you are getting better than a 2.95% return on that money market account. Pay cash. That's the purely logical way to make the decision. However if it were me I'd pay cash anyway just because I like the idea of not owing money and having the hassle of dealing with a payment every month. One additional reason to pay with cash rather than financing is that you will be able to completely shut down the dealership from haggling over finance terms and get right to the point of haggling over the cost of the car (which you should always do). I'd pay cash.  Car loans are amortized, so sometimes you can get upside-down on the loan between 18-30 months because you are pre-paying interest. This can get you into trouble if you get into an accident. Given the low rate and the type of car you're buying, you're probably fine either way.
The advice given at this site is to get approved for a loan from your bank or credit union before visiting the dealer. That way you have one data point in hand.  You know that your bank will loan w dollars at x rate for y months with a monthly payment of Z. You know what level you have to negotiate to in order to get a better deal from the dealer. The dealership you have visited has said  Excludes tax, tag, registration and dealer fees. Must finance through   Southeast Toyota Finance with approved credit. The first part is true. Most ads you will see exclude tax, tag, registration. Those amounts are set by the state or local government, and will be added by all dealers after the final price has been negotiated. They will be exactly the same if you make a deal with the dealer across the street. The phrase Must finance through company x is done because they want to make sure the interest and fees for the deal stay in the family. My fear is that the loan will also not be a great deal. They may have a higher rate, or longer term, or hit you with many fee and penalties if you want to pay it off early. Many dealers want to nudge you into financing with them, but the unwillingness to negotiate on price may mean that there is a short term pressure on the dealership to do more deals through Toyota finance. Of course the risk for them is that potential buyers just take their business a few miles down the road to somebody else. If they won't budge from the cash price, you probably want to pick another dealer. If the spread between the two was smaller, it is possible that the loan from your bank at the cash price might still save more money compared to the dealer loan at their quoted price. We can't tell exactly because we don't know the interest rates of the two offers. A couple of notes regarding other dealers. If you are willing to drive a little farther when buying the vehicle, you can still go to the closer dealer for warranty work. If you don't need a new car, you can sometimes find a deal on a car that is only a year or two old at a dealership that sells other types of cars. They got the used car as a trade-in. "There's two scenarios: the loan accrues interest on the remaining balance, or the total interest was computed ahead of time and your payments were averaged over x years so your payments are always the same. The second scenarios is better for the bank, so guess what you probably have... In the first scenario, I would pay it off to avoid paying interest. (Unless there is a compelling reason to keep the cash available for something else, and you don't mind paying interest) In the second case, you're going to pay ""interest over x years"" as computed when you bought the car no matter how quickly you pay it off, so take your time. (If you pay it earlier, it's like paying interest that would not have actually accrued, since you're paying it off faster than necessary) If you pay it off, I'm not sure if it would ""close"" the account, your credit history might show the account as being paid, which is a good thing." "You want to know if you should pay cash or use a credit card like cash? There are so many benefits to the card, like purchase protection, cash back, and postponed payments, that there needs to be a really good reason to pay cash.  If you are concerned about the 10% threshold, ask your credit card company to raise your limit.  If you are indifferent, let the merchant decide for you by asking for a discount if you pay cash.  The biggest reason is that credit cards, when handled shrewdly, make your money work for you by keeping it in less liquid / higher interest investments like inflation-adjusted T-bills. You will still be able to access it by using the credit card to float large expenses without liquidating at a loss. Investment Accounts like Schwab One are great for this since you can ""borrow"" cash at a low interest rate against your securities, until your security sale clears." Your practice of waiting until you can pay cash is a good one. It will certainly prevent you from getting into debt! Now, to be clear, your question puts a credit card in the same category as a loan, but it doesn't have to be. You could use a credit card almost like cash, if you are careful. I'm not familiar with the system in France, but in the US, even if you are paying cash all the time, there are some benefits to getting a credit card and paying it off in full every month, instead of simply paying with cash. Some of those benefits are: One pretty big downside of having a credit card depends on your personality. Some people, once they have credit, end up spending beyond their means, and end up getting into debt. Please look into whether credit cards work the same way in France before considering the above advice. As for your question regarding getting a loan vs paying cash, that will usually be personal preference, since with a loan you can buy expensive items (such as a house or car) much sooner than you otherwise could if you waited until you saved the money. For example, it might take 10 years or more to build up enough money to purchase a house with cash, so if you don't want to wait that long, you'll need to finance it. Two adages come to mind. Never finance a depreciating asset. If you can't pay cash for a car, you can't afford it. If you decide you can finance at a low rate and invest at a higher one, you're leveraging your capital.  The risk here is that your investment drops in value, or your cash flow stops and you are unable to continue payments and have to sell the car, or surrender it. There are fewer risks if you buy the car outright.  There is one cost that is not considered though.  Opportunity cost.   Since you've declared transportation necessary, I'd say that opportunity cost is worth the lower risk, assuming you have enough cash left after buying a car to fund your emergency fund. Which brings me to my final point.  Be sure to buy a quality used car, not a new one.  Your emergency fund should be able to replace the car completely, in the case of a total loss where you are at fault and the loss is not covered by insurance. TLDR: My opinion is that it would be better to pay for a quality, efficient, basic transportation car up front than to take on a debt. Buy a car. Vehicle loans, like mortgages, are installment loans. Credit cards are revolving lines of credit. In the US, your credit score factors in the different types of credit you have. Note that there are several methods for calculating credit scores, including multiple types of FICO scores. You could buy a car and drive for Uber to help cash flow the car payments and/or save for your next purchase. As others have suggested, you should be very careful with debt and ask critical questions before taking it on. Swiping a credit card is more about your behavior and self-control than it is logic and math. And if you ever want to start a business or make multi-million dollar purchases (e.g. real estate), or do a lot of other things, you'll need good credit. "You can find out the most money they will loan you for a car loan when you approach your current bank/credit union. They should be willing to layout options based on your income, and credit history. You then have to decide if those terms work for you. There are several dangers with getting loan estimates, they may be willing to lend you more than you can actually handle. They think you can afford it, but maybe you can't. They may also have a loan with a longer term, which does bring the monthly cost down, but exposes you to being upside down on the loan. You then use this a a data point when looking at other lenders. The last place you look is the auto dealer. They will be trying to pressure you on both the loan and the price, that is not the time to do doing complex mental calculations. The Suntrust web page was interesting, it included the quote: The lowest rate in each range is for LightStream's unsecured auto loan   product and requires that you have an excellent credit profile. It also induced the example the rate of 2.19% - 4.24%   for a 24 to 36 month loan of $10,000 to $24,999 for a used car purchased from a dealer. Also note that my local credit union has a new/used loan at 1.49%, but you have to be a member. Sunstrust seems to be in the minority. In general a loan for X$ and y months will have a lower rate if it is secured with collateral.  But Suntrust is offering unsecured loans (i.e. no collateral) at a low rate. The big benefit for their product is that you get the cash today. You can get the cash before you know what you want to buy. You get the cash before you have negotiated with the dealer. That makes that step easier. Now will they in the near future ask for proof you bought a car with the money? no idea. If you went to the same web page and wanted a debt consolidation loan the rate for the same $ range and the same months is: 5.49% - 11.24% the quote now changes to: The lowest rate in each range requires that you have an excellent   credit profile. I have no idea what rate they will actually approve you for. It is possible that if you don't have excellent credit the rate rises quickly, but 4.24% for the worst auto loan is better than 5.49% for the best debt consolidation. Excellent Credit Given the unique nature of each individual’s credit situation,   LightStream believes there is no single definition for ""excellent   credit"". However, we find individuals with excellent credit usually   share the following characteristics: Finally, it should be noted again that each individual situation is   different and that we make our credit judgment based on the specific   facts of that situation. Ultimately our determination of excellent   credit is based on whether we conclude that there is a very high   likelihood that our loan will be repaid in a full and timely manner. All the rates mentioned in this answer are from 15 July 2017." In the UK at least, dealers definitely want you to take finance. They get benefits from the bank (which are not insubstantial) for doing this; these benefits translate directly to increased commission and internal rewards for the individual salesman. It's conceivable that the salesman will be less inclined to put himself out for you in any way by sweetening your deal as much as you'd like, if he's not going to get incentives out of it. Indeed, since he's taking a hit on his commission from you paying in cash, it's in his best interests to perhaps be firmer with you during price negotiation. So, will the salesman be frustrated with you if you choose to pay in cash? Yes, absolutely, though this may manifest in different ways. In some cases the dealer will offer to pay off the finance for you allowing you to pay directly in cash while the dealer still gets the bank referral reward, so that everyone wins. This is a behind-the-scenes secret in the industry which is not made public for obvious reasons (it's arguably verging on fraud). If the salesman likes you and trusts you then you may be able to get such an arrangement. If this does not seem likely to occur, I would not go out of my way to disclose that I am planning to pay with cash. That being said, you'll usually be asked very early on whether you are seeking to pay cash or credit (the salesman wants to know for the reasons outlined above) and there is little use lying about it when you're shortly going to have to come clean anyway. Obviously, the best thing financially would be to continue using your present car, unless it impacts you financially on a regular basis. For example, maintenance or breakdowns impacting your ability to work. An unreliable car also impacts your freedom, for example preventing you from taking road-trips you might want to take or taking up free time with maintenance. Give thought to what it is about your present car that you dislike, both to determine the value you gain from a new car and what's most important to you. Anytime you buy a car, you generally lose thousands of dollars simply driving it off the lot. This is the profit which goes to dealers, salespeople, etc... and not part of the actual value of the car. Cars also depreciate over time, with most of the depreciation happening in the first few years of operation. Many of the newer model cars have additional expenses. (For example, replacement $200 keys or electronic systems that can only be repaired at special facilities.) In addition, if you have insurance (other than the minimum third-party required by law), consider the rate increases and add up the long-term impact of that. Imagine you had invested that money instead at 8% interest over the lifetime of the car. If you don't have insurance, consider what you would do in the unfortunate situation where you were at fault in a collision. Could you afford to lose your investment? Even with safe responsible driving, there is always the potential for road/weather conditions or mechanical failures. If you determine there is sufficient value to be gained from changing vehicles, I would recommend that you buy a vehicle with history from someone privately, doing appropriate background checks and consulting friends or family who know about vehicles and can provide feedback. Do research into the models which interest you ahead of time, read online reviews. Every vehicle generally has known advantages and disadvantages which can take years to discover, so buying an older vehicle gives you the advantage of knowing what to expect. I would say there is probably a reasonable middle ground between using a 1991 vehicle you don't like (that's as old as you are) and getting a relatively new model. Look at what you value in the vehicle, consider all the costs, and find the balance that works best for you. Vehicles from 2000-2005 years are quite affordable and still 10-15 years newer than your car. Here's another way to look at this that might make the decision easier: Looking at it this way you can turn this into a financial arbitrage opportunity, returning 2.5% compared to paying cash for the vehicle and carrying the student loan.  Of course you need to take other factors into account as well, such as your need for liquidity and credit. I hope this helps! I don't see how anyone could give you a hard-and-fast formula, unless they know where to get some applicable statistics. Because several factors here are not a straight calculation. If you don't replace the tires but keeping driving the car, what is the increased probability that you will get into an accident because of the bald tires? How much will bald tires vs new tires affect the selling price of the car? Presumably the longer you drive the car after getting new tires, the less increase this will give to the market value of the car. What's the formula for that? If you keep the car, what's the probability that it will have other maintenance problems? Etc. That said, it's almost always cheaper to keep your current car than to buy a new one. Even if you have maintenance problems, it would have to be a huge problem to cost more than buying a new car. Suppose you buy a $25,000 car with ... what's a typical new car loan these days? maybe 5 years at 5%? So your payments would be about $470 per month. If you compare spending $1000 for new tires versus paying $470 per month on a new car loan, the tires are cheaper within 3 months. The principle is the same if you buy with cash. To justify buying a new car you have to factor in the value of the pleasure you get from a new car, the peace of mind from having something more reliable, etc, mostly intangibles. Alternative: buy a recent-model used car in good condition. Or buy an older car in good condition. Let someone else pay the heavy depreciation that happens the moment you drive a new car off the dealer's lot. The only reason to lend the money in this scenario is cashflow. But considering you buy a $15000 car, your lifestyle is not super luxurious, so $15000 spare cash is enough. I have gotten a letter of credit from my credit union stating the maximum amount I can finance. Of course I don't show  the dealer the letter until after we have finalized the deal. I Then return in 3 business days with a cashiers check for the purchase price.  In one case since the letter was for an amount greater then the purchase price I was able drive the car off the lot without having to make a deposit. In another case they insisted on a $100 deposit before I drove the car off the lot. I have also had them insist on me applying for their in-house loan, which was cancelled when I returned with the cashiers check.  The procedure was similar regardless If I was getting a loan from the credit union, or paying for the car without the use of a loan. The letter didn't say how much was loan, and how much was my money.  Unless you know the exact amount, including all taxes and fees,in advance you can't get a check in advance. If you are using a loan the bank/credit Union will want the car title in their name. Advantage of cash: You can spend the money without having to pay any fees or taxes to get it out. Disadvantage: When inflation is greater than zero, which it has been for many decades, your cash is continually losing value. Advantages of an IRA (Roth or classic): Your money will usually grow as the investments return a profit. You get special tax benefits. Disadvantages: There's risk -- you may lose money. There are tax penalties for withdrawing the money before retirement. In general, you should only put money in an IRA if you expect to leave it there until you retire. Or at least, for a long time. Whole life is a combination of a life insurance policy and an investment. Advantages: Combines insurance and investment into one convenient monthly payment. Disadvantages: The investment portion typically has lower returns than you could get elsewhere. If you have no need for life insurance -- if you're not supporting anyone or you're confidant they could get along without you or you don't like them and don't care what happens to them when you're gone or whatever -- then there's no point buying life insurance, whole or term. You're paying for a product that you don't need. It's pretty common advice to tell people that instead of buying a whole life policy, they should buy a term policy with the same coverage, and then invest the difference in the premium. For example, if you were considering getting a $100,000 whole life policy that costs $50 per month (just making up numbers, of course it depends on your age, health, etc), and you see you could get a $100,000 term life policy for $30 per month, you will almost certainly do better in the long run to buy the $30 term policy and put the other $20 into investments. The catch to this plan is that there are usually transaction costs to investing. Even a discount broker like Ameritrade or Scott Trade charges around $10 per transaction. So if you tried to invest $20 each month, you'd lose half of it to transaction fees. Which means that in practice, you'd have to save that money up until you had at least a few hundred. And at that point many people find other things always seem to come up to spend the money on, so that while they start out with every intention of investing this money, they don't.
