When's 0% financing the least costly (best) option?
A Lease is an entirely different way of getting a car. In two situations it makes sense, in all other scenarios it generally doesn't make sense to lease. In the case of always wanting a new car every 2 or 3 years it can make sense to lease. Of course if you drive more the allowed miles you will pay extra at the end of the lease. If you can take the monthly lease as a business expense leasing makes sense. Otherwise you want to pay cash, or get financing. Does zero percent make sense? Sometimes. The only way to make sense of the numbers is to start with your bank, have them approve of the loan first. Then armed with the maximum loan amount they will give you and the rate and the length of the loan, then visit the dealer. You have to run the numbers for your situation. It depends on your income, your other expenses, your credit score, your bank, what deal the dealership is running, how much you have for a down payment. Here is an example. For a recent loan situation I saw: 36 months, 1.49% rate, 20K loan, total interest paid: ~$466. Armed with that information can the person get a better deal at the dealership? There was only one way to find out. In that case the credit union was better. The rebate was larger than the interest paid.
Zero percent interest may sound great, but those deals often have extra margin built into the price to make up for it. If you see 0%, find it cheaper somewhere else and avoid the cloud over your head. "Interest rates are at a record low and the government is printing money. You can get a fixed rate loan at a rate equal to inflation in a healthy economy. Unless you know that you are moving in < 5 years, why would you expose yourself to interest rate risk when rates are about as close to zero as they can be? If your thought with respect to mitigating interest rate risk is: ""What's the big deal, I'll just refinance!"", think again, because in a market where rates are climbing, you may not be able to affordably refinance at the LTV that you'll have in 5-7 years.  From 1974-1991, 30 year mortgages never fell below 9%, and were over 12% from 1979 to 1985. Think about what those kinds of rates -- which reduce a new homeowner's buying power by over 40%, would do to your homes value." If you have enough money to buy a car in full, that probably means you have good credit. If you have good credit, car dealerships will often offer 0% loans for either a small period of time, like 12 months, or the entire loan. Taking a 0% loan is obviously more optimal than paying the entire lump sum up front. You can take the money and invest in other things that earn you more than 0%. However, most dealerships offer a rebate OR a 0% loan. Some commenters below claim that the rebate is usually larger than the saved interest, so definitely do the math if you have that option. If you're getting 0% on the financing, it's not costing you anything to borrow that money. So its basically free money. If you are comfortable with the monthly payments, consider going with no downpayment at all. Keep that money aside for a rainy day, or invest it somewhere so that you get some return on it. If you need to lower the payments later you can always use that money to pay down part of the loan later (check with the dealer that it is an open loan). If you're not comfortable with the payments at 0 down, put enough down to bring the monthly payment to a level where you are comfortable. I think is an excellent idea. Use free money or almost free to do a lump sump payment. My recommendation is to have a reminder to pay credit card before, almost finishing, the 0% APR period. If (and only if) there is a zero interest installment plan available, technically the only uncontrollable risk is that there will likely be a hard inquiry on your credit report which may or may not also have a corresponding debt obligation attached to it. (Personally, I recently signed up for one such plan with Google and I had a hard inquiry but no debt added to my report). The other risks are that 1) your monthly payment goes up, so if you are living on a tight budget the added payment might make it harder to meet your next bill, and 2) you could miss a payment which generally triggers interest to accrue retroactively at a high rate, and in some cases could be grounds for immediate repayment. The pro / reward of these plans is that you have to spend less of your capital upfront, which you may be able to use for other purposes (presumably with a higher net present value than purchasing the item you're considering outright). A larger example would be purchasing a new car. You want to buy a $50k car and you have the cash on hand to pay in full, but you are being offered 0% interest for 36 months. You may be more inclined to take a loan at 0% with 0 down payment and invest your money in another vehicle (no pun intended) that offers you a decent rate of return and you will come out ahead in the end. Of course, this example works in a perfect world where you can get such an offer, there are no extra fees available, you aren't worrying about your debt-to-income ratio in preparation for a big purchase like a house, there isn't a higher insurance premium to consider, etc. In short, 0% financing, be it for a phone or a car, can be a nice perk for the informed consumer who is not using the financing as a way to purchase outside their financial means, but it is offered by companies as a way to make people buy things they normally would not and, hopefully, capitalize on people missing payments in order to reap the sweet 20%+ interest rates generally seen with these offers.  In your specific situation with the phone, you should consider if you get a discount on your monthly plan for purchasing outright, or if you can get the phone subsidized if you sign a contract (and you know you like your provider enough to stay for its duration). If the monthly plan rate stays the same and you're looking at either $500 now or $500 over 24 months and you don't mind a hard inquiry, there's not much of compelling reason to pass on the financing and hold on to your $500. A friend recently bought an 800€ TV on 0% financing. Sounded like a sensible thing to do. Why pay 800 when you can pay 80pm for 10 months? It took 30mins to set up the 'loan'. She had to sign all kinds of documents, giving away much personal information (age, employment info, income, email address etc). She now has a financial relationship with an institution which has nothing to do with the item purchased. She is bombarded with all kinds of financial offerings. She regrets taking out the finance. She had the money. The hassle and the unwanted links to banks make the deal unattractive. Perhaps she should have tried to make a cash deal... I struggle with 0% interest things in my personal life.  A responsible me that thinks logically says continue to pay it on time and take advantage of the benefit of the interest free loan you got. It will keep your funds liquid in the case of an emergency, build your credit and teach you self control.  Paying it off now has little to no benefit. It does however tie up $3,000 worth of capital you could be using for building interest or leveraging against other purchases. There many car loans at zero percent interest.   Finance the car at zero percent, then take your money and invest it. If you want to be super safe buy a CD the same length as the car loan. 5 years you will get 2%.  If you still want safety and a better return take up a asset allocation strategy that moves your cash to risky assets when the market is performing well, then to cash, bonds, or cds when the market under-performs. Now you have your car with a zero percent loan and you are making the return on the money instead of the car company. Sometimes there are credit cards that offer a (promotional) 0% APR on transfers with no transfer fees.  It can be a good option to move the money to one of these if you're disciplined enough to keep hacking away at the debt before the APR jumps. Sometimes I think it helps to think of the scenario in reverse. If you had a completely paid off car, would you take out a title loan (even at 0%) for a few months to put the cash in a low-interest savings account? For me, I think the risk of losing the car due to non-payment outweighs the tens of dollars I might earn. Remember that balance transfers are rarely fee free. As you state, there is a fee associated with the balance transfer. If your 0% rate is for 18 months and the fee is 3%, you are really paying 2% per year on the amount you transferred. The advantage is that you can redirect the debt you transferred is interest free and you can attack other debt with high interest on it. This can save you in interest fees and allow you to direct more of your money towards debt. The disadvantage is that your 0% interest will expire and become a much higher interest rate. Unless you pay off the transfer before the expiration, you will have to pay off the debt at the higher interest. How you decide to attack your debt reduction may need to factor in how long you expect to have debt and what other debt you have. Often times though, the savings in interest is less important than simplifying the number of debt accounts you have. The inspiration you receive from reducing your debt accounts is much more powerful. You realize reducing debt accounts allows you to actually see an end in sight and provides the recurring positive feedback that you are making progressing. This is why the advice to pay off your lowest balance credit cards first. "Your use of the term ""loan"" is confusing, what you're proposing is to open a new card and take advantage of the 0% APR by carrying a balance.  The effects to your credit history / score will be the following:" "I'd put more money down and avoid financing. I personally don't think car debt is good debt and if you can't afford the car, you are better off with a cheaper car. Also, you should read up on the 0% offer before deciding to commit.   Here's one article that is slightly dated, but discusses some pros and cons of 0% financing. My main point though is that 0% financing is not ""free"" and you need to consider the cost of that financing before making the purchase.  Aside from the normal loan costs of having a monthly payment, possibly buying too much car by looking at monthly cost, etc., a 0% financing offer usually forces you to give the dealer/financing company any rebates that are due to you, in essence making the car cost more." I also had a student loan and glad you are taking a good look on interest rate as it really makes a huge difference. One of the strategies I followed was since my credit improved as I stepped out of school. I took advantage of a good 0 percent credit card. I applied for discover and got a decent credit limit. There are 2 particular things you are looking for in a credit card in this situation  Usually the initial $0 transaction charge is only for a couple of months so ensure you take advantage of that. What is the benefit: Imagine being able to pay off that higher interest rate balance with 0% and not have to worry about it immediately. That way you save on the interest you would be paying and stress as well Watch out for: Although you have to ensure that you do payoff the money you paid through the 0 percent credit card ( which may have been put off for a year or even 15 months or so) other wise you may have to pay it all at once as the offer is expiring. Note: for credit cards ensure to note when the 0% is expiring as that is usually not mentioned on the statement and you may have to call the customer service. I was in a similar situation and was able to pay it all off fairly quickly. I am sure you will as well.
