Strategy to pay off car loan before selling the car
As far as ease of sale transaction goes you'll want to pay off the loan and have the title in your name and in your hand at the time of sale.  Selling a car private party is difficult enough, the last thing you want is some administrivia clouding your deal.  How you go about paying the remaining balance on the car is really up to you.  If you can make that happen on a CC without paying an additional fee, that sounds like a good option.
The main benefit of paying off the loan early is that it's not on your mind, you don't have to worry about missing a payment and incurring the full interest due at that point. Your loan may not be set up that way, but most 0% interest loans are set up so that there is interest that's accruing, but you don't pay it so long as all your payments are on time, oftentimes they're structured so that one late payment causes all of that deferred interest to be due.  If you put the money in the bank you'd make a small amount of interest and also not have to worry about funds availability for your car payment. If you use the money for some other purpose, you're at greater risk of something going wrong in the next 21 months that causes you to miss a payment and being hit with a lot of interest (if applicable to your loan).  If you already have an emergency fund (at least 3-6 months of expenses) then I would pay the loan off now so you don't have to think about it.  If you don't have an emergency fund, then I'd bank the money and keep making payments, and pay it off entirely when you have funds in excess of your emergency fund to do so. "Having just gone through selling a car, I can tell you that CarMax will most likely not be the best solution. I recently sold my '09 Pontiac Vibe which had a KBB and Edmonds value (private party sale) of around $6k. Trade-in value was around $4,800. I took it to the local CarMax for a quote, and they came back with $3,500.  Refinancing is tricky. Banks have a set limit on how old a car they will finance. Many won't even offer financing if the vehicle has over 100k miles. We looked at refinancing our other car, and even getting the APR down over a point we would only have saved $15/mo or so. Banks typically offer much higher interest rates for used non-dealership cars and refinancing than they do for new cars, or even used cars purchased from a dealership. Assuming you have 2-3 years left on your loan, I don't think that refinancing would save you enough to be worth considering. CarMax sells cars in 1 of 2 ways. They are also up front with you about the process. They do not reference KBB or Edmonds or any other valuation tool other than their own internal system. They either take the car, spruce it up a bit, then resell it on their lot, or they sell it at auction. If they determine your car will be sold at auction, then they will offer you a rock bottom price. The determining factors that come into play include age of the car, mileage, and of course overall condition. If you Mini is still in good shape and doesn't have a lot of miles, then they may try to resell it on their lot, for which they could offer you closer to personal-sale price than trade-in. How many 2007's are for sale in your area? How much are they selling for? I did sell them a truck back in 2005 and received $200 more than KBB valued it for, but it was in great shape, only a couple of years old, relatively low mileage, and it was in high demand. God bless the South and their love for trucks! I ended up selling my Pontiac to another local car dealership. They offered me $5,300 (after negotiating, leaving the dealership, then negotiating more over the phone). It took me a day and a half and really very little effort. I have several friends that have gone through the same thing with selling cars, and all have had similar luck going to other dealerships, where prices can be negotiated, rather than CarMax.  CarMax has no incentive to ""settle"" or forgive your loan. If you really want to pay it off, save up what you believe the difference will be, then shop your car around the local dealerships and get prices for your Mini. Remember that dealers have to turn a profit, so be reasonable with your negotiation. If you can find comparable vehicles in your area listed for $X,000 then knock $1,500 off that price and tell the dealerships that's what you want." Assuming that partial payments are held (without interest) until enough money has accumulated to make at least a full payment, and assuming that overpayments are applied toward principal, a strategy of making three $ 96.00 payments per month will shorten your amortization period by less than one month.  These calculations assume that the interest rate is 12.5 percent APR, compounded monthly (with an APY of 13.2416 percent). Instead of 71 payments of $ 285.56 plus a final payment of $ 285.38, you would make the equivalent of 71 payments of $ 288.00 plus a final payment of $ 28.10. If you make one $ 96.00 payment every ten days, you will make an average of 36.5… partial payments per year, instead of 36 partial payments per year.  This will speed up your loan amortization by about another month-and-a-half over the course of the 72 month loan.  One month of shortening is due to the extra principal payments, and the other half-month is due to interest savings.   To a second approximation, this strategy is similar to paying $ 292.00 per month for 69 months plus a final payment of $ 195.38.  In other words, this strategy will probably involve about 212 payments of $ 96.00 each, possibly with a small 213th payment. You have a good start (estimated max amount you will pay, estimated max down payment, and term) Now go to your bank/credit union and apply for the loan. Get a commitment. They will give you a letter, you may have to ask for it. The letter will say the maximum amount you can pay for the car. This max includes their money and your down payment. The dealer doesn't have to know how much is loan. You also know from the loan commitment exactly how much your monthly payment will be in the worst case. If you have a car you want to trade in, get an written estimate that is good for a week or so. This lets you know how much you can get from selling the car. Now visit the dealer and tell them you don't need a loan, and won't be trading in a car. Don't show them the letter. After all the details of the purchase are concluded, including any rebates and specials, then bring up financing and trade-in. If they can't beat  the deal from your bank and the written estimate for the car you are selling, then the deal is done. Now show them the letter and discuss how much down they need today. Then go to the bank for the rest of the money. If they do have a better loan deal or trade in then go with the dealer offer, and keep the letter in your pocket. If you go to the dealer first they will confuse you because they will see the price, interest rate, length of loan, and trade in as one big ball of mud. They will pick the settings that make you happy enough, yet still make them the most money. "It's not a bad strategy. I'd rather owe money at 4% interest than at 6-7%. However, there is something to consider.  Consolidating debt into a new loan can backfire. When you have money borrowed at 7%, you want to get that paid off as quickly as possible. Once you have that converted to 4%, if you think, ""Now I can take my time paying off this debt,"" then you aren't really better off. In fact, if you take too long paying off the new loan, you might end up paying more interest than if you had kept the high interest loan and paid it as soon as possible. Don't lose your drive to get out of debt after you refinance.  As far as how the student loans affect your debt-to-income ratio, I'm not sure; however, if they do count (I think they do), your ratio will not really be going up by taking out the new loan, since you are using the money to pay other debt. Make sure the new lender knows this, so they take that into consideration when making their decision.  Overall, I like your strategy: pay off what you can right away (the car loan and the highest interest student loans) and reduce the interest on the rest. Just make sure that you continue to pay down that debt as quick as you can." "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." I don't disagree with the current answers, but I feel like no one really answered your question directly.  Seems to me like what you were asking is when to trade in your car in relation to when/whether your loan is paid off? Assuming you are committed to trading your car in (and not selling it privately as has been suggested), whether the car is paid off should have no impact on what you get for a trade-in.  The car is worth what it's worth, and what you owe on it should not affect the transaction. Do you need the car? It depends on what your goals are. You're going to keep losing money on the car via means of the debt (which I assume you can't pay off without selling the car) and depreciation. If it was me, I would sell the car. But if you like it and you can afford it, then keep it. If the car loan has 0% interest for 5 years, then paying off the student loan is cheaper. No matter when you pay off the car, you will pay the exact same amount (as long as its within 5 years). You could spend $20,000 right now to pay off the car loan or slowly spend $20,000 over the next 5 years. The gross amount paid for the car loan does not change. On the contrary, the longer you wait to pay off the student loans, the more you will end up paying for them. So why not get the student loans out of the way before they rack up more interest and pay the car loan over time? Update: I forgot to add, as Ben Miller said, congratulations on paying off the $40,000! "Following up on @petebelford's answer: If you can find a less expensive loan, you can refinance the car and reduce the total interest you pay that way. Or, if your loan permits it (not all do; talk to the bank which holds the loan and,/or read the paperwork you didn't look at), you may be able to make additional payments to reduce the principal of the loan, which will reduce the amount and duration of the loan and could significantly reduce the total interest paid ... at the cost of requiring you pay more each month, or pay an additional sum up front. Returning the car is not an option. A new car loses a large portion of its value the moment you drive it off the dealer's lot and it ceases to be a ""new"" car. You can't return it. You can sell it as a recent model used car, but you will lose money on the deal so even if you use that to pay down the loan you will still owe the bank money. Given the pain involved that way, you might as well keep the car and just try to refinance or pay it off. Next time, read and understand all the paperwork before signing.  (If you had decided this was a mistake within 3 days of buying, you might have been able to take advantage of ""cooling down period"" laws to cancel the contract, if such laws exist in your area. A month later is much too late.)" Everybody on the car title will need to participate in the selling process. The person who is buying the car will need everybody to sign the paperwork so that nobody months later tries to say they never agreed to sell the car. The money will have to be sent to the lender to pay off the rest of the loan. If the money isn't enough to pay off the loan everybody will have to decide how the extra money will be sent to the lender. This will have to be done as part of the selling process because the lender doesn't want you to sell the car and keep the cash. Once the car is gone so is the collateral and they can't take it back if you miss payments.  If the cousin is too far away to participate in the selling of the car, you may need the buyer and the lender to tell you how to proceeded. If you are selling at a dealership they will know what documents and signatures will be needed, the bank will also know what to do. If the loan is almost paid off it may be easier to pay the loan first, and then get the title without the lenders name before trying to sell it. 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. The optimal down payment is 0% IF your interest rate is also 0%. As the interest rate increases, so does the likelihood of the better option being to pay for the car outright. Note that this is probably a binary choice. In other words, depending on the rate you will pay, you should either put 0% down, or 100% down. The interesting question is what formula should you use to determine which way to go? Obviously if you can invest at a higher return than the rate you pay on the car, you would still want to put 0% down. The same goes for inflation, and you can add these two numbers together. For example, if you estimate 2% inflation plus 1% guaranteed investment, then as long as the rate on your car is less than 3%, you would want to minimize the amount you put down. The key here is you must actually invest it. Other possible reasons to minimize the down payment would be if you have other loans with higher rates- then obviously use that money to pay down those loans before the car loan. All that being said, some dealers will give you cash back if you pay for the car outright. If you have this option, do the math and see where it lands. Most likely taking the cash back is going to be more attractive so you don't even have to hedge inflation at all. Tip: Make sure to negotiate the price of the car before you tell them how you are going to pay for it. (And during this process you can hint that you'll pay cash for it.) "Wow, you guys get really cheap finance. here a mortage is 5.5 - 9% and car loans about 15 - 20%. Anyway back to the question. The rule is reduce the largest interest rate first (""the most expensive money""). For 0% loans, you should try to never pay it off, it's literally ""free money"" so just pay only the absolute minimum on 0% loans.  Pass it to your estate, and try to get your kids to do the same.  In fact if you have 11,000 and a $20,000 @ 0% loan and you have the option, you're better to put the 11,000 into a safe investment system that returns > 0% and just use the interest to pay off the $20k. The method of paying off the numerically smallest debt first, called ""snowballing"", is generally aimed at the general public, and for when you can't make much progress wekk to week.  Thus it is best to get the lowest hanging fruit that shows progress, than to try and have years worth of hard discipline just to make a tiny progress.  It's called snowballing, because after paying off that first debt, you keep your lifestyle the same and put the freed up money on as extra payments to the next target.  Generally this is only worth while if (1) you have poor discipline, (2) the interest gap isn't too disparate (eg 5% and 25%, it is far better to pay off the 25%, (3) you don't go out and immediately renew the lower debt.  Also as mentioned, snowballing is aimed at small regular payments.  You can do it with a lump sum, but honestly for a lump sum you can get better return taking it off the most expensive interest rate first (as the discipline issue doesn't apply). Another consideration is put it off the most renewable finance.  Paying off your car... so your car's paid off.  If you have an emergency, redrawing on that asset means a new loan.  But if you put it off the house (conditional on interest rates not being to dissimilar) it means you can often redraw some or all of the money if you have an emergency.  This can often be better than paying down the car, and then having to pay application fees to get a new unsecured loan.   Many modern banks actually use ""mortgage offsetting"" which allows them to do this - you can keep your lump sum in a standard (or even fixed term) and the value of it is deducted ""as if"" you'd paid it off your mortgage.  So you get the benefit without the commitment.  The bank is contracted for the length of the mortgage to a third party financier, so they really don't want you to change your end of the arrangement.  And there is the hope you might spend it to ;) giving them a few more dollars.  But this can be very helpful arragement, especially if you're financing stuff, because it keeps the mortgage costs down, but makes you look liquid for your investment borrowing." The other answers have offered some great advice, but here is an alternative that hasn't been mentioned yet. I'm assuming that you have an adequately-sized emergency fund in savings, and that your cars are your only non-mortgage debt. Since you still have car debt, you probably don't have anything saved for buying a new car when your current cars are at the end-of-life. Consider paying off your car loans early, then begin saving for your next car. Having cash in the bank for a car is very freeing, and it changes your mindset when it comes time to purchase a car, as it is easy to waste a lot of money on something that depreciates rapidly when you aren't paying for it immediately.  This approach might be counterintuitive if your car loan interest rate is less than your mortgage rate, but you will probably need another car before you need another house, and paying cash for a car is worth doing.
