For a car, what scams can be plotted with 0% financing vs rebate?
The car deal makes money 3 ways. If you pay in one lump payment. If the payment is greater than what they paid for the car, plus their expenses, they make a profit. They loan you the money. You make payments over months or years, if the total amount you pay is greater than what they paid for the car, plus their expenses, plus their finance expenses they make money. Of course the money takes years to come in, or they sell your loan to another business to get the money faster but in a smaller amount. You trade in a car and they sell it at a profit. Of course that new transaction could be a lump sum or a loan on the used car... They or course make money if you bring the car back for maintenance, or you buy lots of expensive dealer options. Some dealers wave two deals in front of you: get a 0% interest loan. These tend to be shorter 12 months vs 36,48,60 or even 72 months. The shorter length makes it harder for many to afford. If you can't swing the 12 large payments they offer you at x% loan for y years that keeps the payments in your budget. pay cash and get a rebate. If you take the rebate you can't get the 0% loan. If you take the 0% loan you can't get the rebate. The price you negotiate minus the rebate is enough to make a profit. The key is not letting them know which offer you are interested in. Don't even mention a trade in until the price of the new car has been finalized. Otherwise they will adjust the price, rebate, interest rate, length of loan,  and trade-in value to maximize their profit. The suggestion of running the numbers through a spreadsheet is a good one. If you get a loan for 2% from your bank/credit union for 3 years and the rebate from the dealer, it will cost less in total than the 0% loan from the dealer. The key is to get the loan approved by the bank/credit union before meeting with the dealer. The money from the bank looks like cash to the dealer. "Here's a number-crunching example of how the ""Zero interest rate"" offer is misleading. Suppose the offer is that a car ""costs $24,000.00 with zero percent financing over 24 months""  or as an alternative, ""$3,000.00 off for cash"". Ignore the hype:  the quoted prices and the quoted interest rates.  Look at what really happens to two people who take advantage of the two offers, One person hands over $21,000.00 cash, and leaves with the new car. The second promises to make 24 payments of $1000.00, one a month, starting in one month's time, and also leaves with the same make and model new car. The two people have received exactly the same benefit, so the two payment schemes must have the same value. A mortgage program will tell you that paying off a $21,000.00 loan by making 24 monthly payments of $1000.00 requires an interest rate of 1.10% a month, or an effective annual rate of 14.03%."
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. "I cannot stress this enough, so I'll just repeat it:  Don't plan your finances around your credit score.  Don't even think about your credit score at all.  Plan a budget an stick to it.  Make sure you include short and long term savings in your budget.  Pay your bills on time.  Use credit responsibly.  Do all of these things, and your credit rating will take care of itself.  Don't try to plan your finances around raising it. On the subject of 0% financing specifically, my rule of thumb is to only ever use it when I have enough money saved up to buy the thing outright, and even then only if my budget will still balance with the added cost of repaying the loan.  Other people have other rules, including not taking such loans at all, and you should develop a rule that works for you (but you should have a rule).  One rule shouldn't have is ""do whatever will optimize your credit score"" because you shouldn't plan your finances around your credit score.   All things considered, I think the most important thing in your situation is to make sure that you don't let the teaser rate tempt you into making purchases you wouldn't otherwise make.  You're not really getting free money; you're just shifting around the time frame for payment, and only within a limited window at that.  Also, be sure to read the fine print in the credit agreement; they can be filled with gotchas and pitfalls.  In particular, if you don't clear the balance by the end of the introductory rate period, you can sometimes incur interest charges retroactively to the date of purchase.  Make sure you know your terms and conditions cold. It sounds like you're just getting started, so best of luck, and remember that Rome wasn't built in a day.  Patience can be the most effective tool in your personal finance arsenal. p.s. Don't plan your finances around your credit score." I haven't heard of these before!  (And I'm on the board of a Credit Union.) The 0.99% on loans is great.  It's especially great on a used car: the steep part of the depreciation curve was paid by the first owner. The network probably have a business relationship with the credit union.  Credit unions do indirect lending -- approval of loans that happens at the point of sale, which then the credit union gets as assets. Depending on the cost of that program, it probably won't hurt.  Your credit union wants to keep your business, because they know that you have a lot of options for where you bank and where you get loans. 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 could be mistaken on this, but after the GM bailout and others, weren't laws put in place to essentially force companies to maintain a certain level of liquidity? Also, that 0% is probably closer to .25~.50 through way of credit swaps, no? Or if we assume it's earning .1%, that's still $6,666,667/month ($80,000,000,000 x .001/12). "This is completely disgusting, utterly unethical, deeply objectionable, and yes, it is almost certainly illegal. The Federal Trade Commission has indeed filed suit, halted ads, etc in a number of cases - but these likely only represent a tiny percentage of all cases. This doesn't make what the car dealer's do ok, but don't expect the SWAT team to bust some heads any time soon - which is kind of sad, but let's deal with the details. Let's see what the Federal Trade Commission has to say in their article, Are Car Ads Taking You for a Ride? Deceptive Car Ads Here are some claims that may be deceptive — and   why: Vehicles are available at a specific low price or for a specific   discount What may be missing: The low price is after a downpayment, often   thousands of dollars, plus other fees, like taxes, licensing and   document fees, on approved credit. Other pitches: The discount is only   for a pricey, fully-loaded model; or the reduced price or discount   offered might depend on qualifications like the buyer being a recent   college graduate or having an account at a particular bank. “Only $99/Month” What may be missing: The advertised payments are temporary “teaser”   payments. Payments for the rest of the loan term are much higher. A   variation on this pitch: You will owe a balloon payment — usually   thousands of dollars — at the end of the term. So both of these are what the FTC explicitly says are deceptive practices. Has the FTC taken action in cases similar to this? Yes, they have: “If auto dealers make advertising claims in headlines, they can’t take   them away in fine print,” said Jessica Rich, Director of the FTC’s   Bureau of Consumer Protection. “These actions show there is a   financial cost for violating FTC orders.” In the case referenced above, the owners of a 20+ dealership chain was hit with about $250,000 in fines. If you think that's a tiny portion of the unethical gains they made from those ads in the time they were running, I'd say you were absolutely correct and that's little more than a ""cost of doing business"" for unscrupulous companies. But that's the state of the US nation at this time, and so we are left with ""caveat emptor"" as a guiding principle. What can you do about it? Competitors are technically allowed to file suit for deceptive business practices, so if you know any honest dealers in the area you can tip them off about it (try saying that out loud with a serious face).  But even better, you can contact the FTC and file a formal complaint online. I wouldn't expect the world to change for your complaint, but even if it just generates a letter it may be enough to let a company know someone is watching - and if they are a big business, they might actually get into a little bit of trouble." The bank depends on the laws of large numbers.  They don't need to make money on every customer -- just on average. There are several ways that zero interest makes sense to them: You asked about banks, and I don't think you see this last scheme in use very much by a bank.  Here's why.   First, customers absolutely hate it - and when you drop the interest bomb, they will warn their friends away, blow you up on social media, call the TV news consumer protectors, and never, ever, ever do business with you again.  Which defeats your efforts in customer acquisition.  Second, it only works on that narrow range of people who default just a little bit, i.e. who have an auto-pay malfunction.  If someone really defaults, not only will they not pay the punishment interest, they won't pay the principal either!  This only makes sense for secured loans like furniture or cars, where you can repo that stuff - with unsecured loans, you don't really have any power to force them to pay, short of burning their credit.  You can sue them, but you can't get blood from a stone. "The question is about the dealer, right?  The dealer isn't providing this financing to you, Alfa is, and they're paying the dealer that same ""On the Road"" price when you finance the purchase.  So the dealer gets the same amount either way. The financing, through Alfa, means your payments go to Alfa.  And they're willing to give you 3,000 towards purchase of the car at the dealer in order to motivate those who can afford payments but not full cash for the car.  They end up selling more cars this way, keeping the factories busy and employees and stockholders happy along the way.  At least, that's how it's supposed to work out." First of all, congratulations on paying off $40k in debt in one year. Mathematically, you'd be better off making the standard car loan payments and putting your extra money toward the student loan. However, there are a few other things that you might want to consider. Over the last year, you've knocked out a whole bunch of different debts.  Feels pretty good, doesn't it?  At your current rate, you could knock out your new car loan in 6 months.  Then you'd only have one debt left.  If it sounds to you like it would be nice to only have one debt left, then it might be worth the mathematical disadvantage you would get by paying off the car early instead of putting the money toward the last student loan. The car loan is 0%, but if you are late on a single payment, they will take that opportunity to raise your interest rate to something probably higher than the interest rate of your student loan.  For this reason, you may decide it is not worth the hassle, and you'd rather just eliminate the car loan as quickly as possible. Either choice is fine, in my opinion, as long as you have a purpose behind the choice and you are committed to eliminating both debts as quickly as possible. As an aside, it is important to remember that even a 0% loan is not really free money, and needs to be paid back.  You know this, of course, but sometimes you see a 0% loan advertized and it feels like free money.  It's not.  You have probably already paid for the loan by forfeiting a rebate.  So although, at this point having already taken this loan and paying for it, you will come out ahead by dragging out your car loan for the full term, in the future do not think that you can make money by buying something at 0% interest. That interest rate (13%) is steep, and the balloon payment will have him paying more interest longer. Investing the difference is a risky proposition because past performance of an investment is no guarantee of future performance. Is taking that risk worth netting 2%? Not for me, but you must answer that last question for yourself. To your edit: How disruptive would losing the car and/or getting negative marks on your credit be? If you can quantify that in dollars then you have your answer. "As reported by ZeroHedge in January 2016:   ""While the media claims that this record has been reached because of drastic improvements to the US economy, they are once again failing to account for the central factor: credit expansion.""   ""In order to generate more vehicle purchases, these companies have incentivized consumers with hot, hard-to-resist offers, similar to the infamous “liar loans” and “no-money down” loans of the 2008 recession.""   http://www.zerohedge.com/news/2016-01-11/auto-loan-bubble-ready-pop.   Pro tip: Get your news over 1 year in advance by reading ZeroHedge and not shitty Bloomberg or other lamestream media." "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." "You are correct to be wary. Car dealerships make money selling cars, and use many tactics and advertisements to entice you to come into their showroom. ""We are in desperate need of [insert your make, model, year and color]! We have several people who want that exact car you have! Come in and sell it to us and buy a new car at a great price! We'll give you so much money on your trade in!"" In reality, they play a shell game and have you focus on your monthly payment. By extending the loan to 4 or 5 years (or longer), they can make your monthly payment lower, sure, but the total amount paid is much higher. You're right: it's not in your best interest. Buy a car and drive it into the ground. Being free of car payments is a luxury!" "as a used dealer in subprime sales, finance has to be higher than cash because every finance deal has a lender that takes a percentage ""discount"" on every deal financed. if you notice a dealer is hesitant to give a price before knowing if cash or finance, because every bit of a cash deal's profit will be taken by a finance company in order to finance the deal and then there's no deal. you might be approved but if you're not willing to pay more for a finance deal, the deal isn't happening if I have $5000 in a car, you want to buy it for $6000 and the finance lender wants to take $1200 as a ""buy-fee"" leaving me $4800 in the end." Most 0% interest loans have quite high interest rates that are deferred. If you are late on a payment you are hit with all the deferred interest. They're banking on a percentage of customers missing a payment.  Also, this is popular in furniture/car sales because it's a way to get people to buy who otherwise wouldn't, they made money on the item sale, so the loan doesn't have to earn them money (even though some will). Traditional banks/lenders do make money from interest and rely on that, they would have to rely on fees if interest were not permitted.
