How Long Should a Car Loan Be? 48 vs. 60 vs. 72 Months

Car loans now commonly stretch to 72 or even 84 months. A longer term makes the monthly payment look smaller, but it changes how much the car really costs and how long you're tied to the loan. Here's how to think about the trade-off.

How term affects your payment

Here is the same $35,000 loan at 7% APR over three different terms (rounded):

Going from 60 to 84 months lowers the payment by about $165 a month, but adds roughly $2,800 in interest — and in real life, longer loans often come with higher interest rates too, which widens the gap further.

The negative equity problem

Cars lose value quickly, often 20% or more in the first year. With a long loan, your balance falls slowly, so for a long stretch you can owe more than the car is worth. That's called being "upside down" or having negative equity. If the car is totaled or you need to sell it, you may have to cover the difference out of pocket, and trading it in often rolls the leftover debt into your next loan.

So what term should you choose?

• 48 months or less is ideal if the payment fits your budget — you'll pay the least interest and build equity fast.
• 60 months is a reasonable middle ground for most buyers.
• 72–84 months should be a last resort. If you need that long to afford the payment, consider a less expensive car.

A popular rule of thumb is the 20/4/10 rule: put at least 20% down, finance for no more than 4 years, and keep total car costs (payment, insurance, fuel) under 10% of your gross income.

How to get a lower payment without a longer loan

• Increase your down payment or wait to save more.
• Get pre-approved by a credit union to compare rates.
• Negotiate the vehicle price, not the monthly payment.
• Skip or pay cash for dealer add-ons instead of financing them.
• Consider a certified pre-owned vehicle.
