36, 48, 60, or 72 Months: How to Choose a Car Loan Term

May 20, 2026

When you finance a car, the loan term — how many months you have to repay — has a bigger effect on your monthly payment than almost any other choice except the loan amount itself. US auto loans commonly run 36, 48, 60, 72, or even 84 months. Picking the right one is a balance between an affordable payment and the total cost of borrowing.

The core trade-off

Stretching a loan over more months lowers the monthly payment because you are spreading the same principal across more installments. But a longer term also means you pay interest for longer, so the total interest rises — sometimes substantially.

Consider a $30,000 loan at a 6.5% APR:

• 48 months: higher monthly payment, but you clear the debt in four years and pay the least total interest.
• 60 months: a noticeably lower payment, with moderately more interest.
• 72 months: the lowest payment of the three, but the most total interest and the longest exposure.

The exact figures depend on your APR, so the most useful thing you can do is compare terms side by side in the auto loan calculator — change only the term and watch how the monthly payment and total interest move in opposite directions.

Why longer terms carry hidden risk

Beyond the extra interest, long terms create a practical problem: being underwater, meaning you owe more than the car is worth. Vehicles depreciate fastest in the first few years, while a long loan pays down principal slowly at the start. With a 72- or 84-month loan, you can spend years owing more than you could sell the car for. That becomes a real problem if the car is totaled, or if you want to trade it in early — you would have to cover the gap out of pocket.

A larger down payment shortens the time you spend underwater. Our guide on how much to put down on a car covers this in more detail.

A simple framework

1. Start with the shortest term you can comfortably afford. Shorter terms save interest and build equity faster.
2. Use the monthly payment as a guardrail, not a target. If a longer term is the only way to fit the payment into your budget, that may be a sign the car is more than you should finance.
3. Avoid 84-month loans unless you have a specific reason. The interest cost and underwater risk are highest, and lenders often charge higher APRs on the longest terms.
4. Match the term to how long you will keep the car. Try not to still be paying for a car you no longer want to own.

What about the APR?

Loan term and APR interact. Lenders sometimes offer slightly higher rates on longer terms because the loan is riskier for them. Your credit also matters — see how your credit score affects your auto loan rate for the typical ranges at each credit tier.

The bottom line

A longer term buys you a lower monthly payment at the cost of more total interest and a longer stretch of owing more than the car is worth. The sensible default is the shortest term that keeps the payment comfortable. Run a few term lengths through the calculator before you sign — seeing the total-interest difference in dollars usually makes the right choice obvious.
