Car loan term and total cost: 48, 60 and 72 months on the same car

The rate anchor and how we ran the numbers

We used the Federal Reserve's G.19 consumer credit release dated October 7, 2026. Its terms-of-credit table reports commercial bank interest rates on new car loans of 7.54 percent for 60-month loans and 7.17 percent for 72-month loans in August 2026, both preliminary figures. For comparison, the 2025 annual figures were 7.65 percent and 7.80 percent. [1] G.19 does not publish a 48-month series, so we ran all three terms at 7.54 percent to isolate the effect of the term, then added a row at the published 72-month rate.

Each scenario is a $30,000 amount financed with level monthly payments, interest charged monthly on the remaining balance, and no fees or add-ons. Figures are rounded to the nearest dollar. Your quote will differ: the CFPB notes that the lower your credit score, the more likely you are to receive a higher interest rate, which costs more over the life of the loan. [5]

Payment and total interest by term

Stretching from 48 to 72 months lowers the payment by about $207 a month, and costs about $2,544 more in interest. The CFPB frames the trade-off the same way: a shorter term, with fewer monthly payments, reduces the overall cost; a longer loan can reduce your monthly payment, but you will pay more interest over the life of the loan. [2] The CFPB also warns that many people think about a loan in terms of the monthly payment when the total cost of the loan is what matters. [2]

In this August 2026 data the published 72-month rate was lower than the 60-month rate. [1] Even at that lower rate, the 72-month loan still costs about $900 more in interest than the 60-month loan at 7.54 percent, because you borrow the money for an extra year.

What you still owe, year by year

The cost that catches people is not only the extra interest; it is the balance. The CFPB explains that at the beginning of an amortizing loan, more of each payment generally goes to interest rather than principal, and that the longer the term, the lower the payment but the more interest you pay. [3] A lower payment also means the principal falls more slowly.

Compare the balance with what the car would fetch as a trade-in or private sale at each point. Get a current valuation quote for your specific car rather than assuming a depreciation rate. Whenever the balance is above that value, you have negative equity.

Why the balance gap matters: negative equity

The CFPB describes negative equity as owing more than your trade-in value, and says a dealer or lender may offer to roll that balance into a new auto loan, which will make the new loan more expensive and increase the interest you pay over its life. [4] If a dealer promises to pay off negative equity, the CFPB says to make sure it is not included in your new financing or final contract, and to check with the old lender about a week later that the previous loan was actually paid off. [4]

Worked example: three years into the 72-month loan above you owe about $16,684. If the best trade-in offer is $14,000, about $2,684 of old debt has to go somewhere: paid in cash, or added to the next loan, where it collects interest again. On the 48-month loan the balance at the same point would be about $8,365, so the same $14,000 offer would leave you with equity rather than debt. A longer term does not cause depreciation, but it widens the window in which the loan can outrun the car's value.

Who a longer term fits, and who should skip it

A longer term can make sense if you plan to keep the car past the payoff date, the rate on the longer term is no higher than the shorter one, and you have checked that paying extra principal is allowed without penalty, so you can pay it down faster when money allows. It is also a reasonable bridge when the payment on a shorter term would crowd out an emergency fund.

Skip it if you tend to trade cars every two or three years, if the longer term is only making room for a more expensive car or for add-ons, or if the 72-month quote carries a higher rate. The CFPB says add-on products are optional and that financing them increases both the monthly payment and the total amount you borrow and repay. [2] It also lists saving for a larger down payment and buying a less expensive vehicle as ways to reduce costs. [5]

Checklist before you pick a term

For how the APR differs from the interest rate on a loan quote, see our APR guide; for the mechanics of why early payments are mostly interest, see our amortization guide.

• Ask for the same loan priced at 48, 60 and 72 months, and compare total of payments, not just the monthly payment. [2]
• Compare the APR on each term; a lower rate and APR means you pay less to borrow. [2]
• Shop lenders within a short window: the CFPB says to keep credit inquiries within 14 to 45 days of each other so they count as one. [5]
• Get a trade-in or private-sale value for your current car before you visit the dealer, and know your payoff amount. [4]
• Decline or price separately any add-ons you do not want; they are optional. [2]
• If you roll negative equity into the deal, confirm the old loan is paid off about a week later. [4]
• Write down the balance you will owe at the end of years two and three, using a schedule like the one above, and compare it with what you expect to keep the car for.
