How long should your car loan be? 36 to 84-month terms compared
A longer auto loan lowers your monthly payment but usually raises the total interest you pay, and it can keep you owing more than the car is worth (negative equity) for longer. The CFPB suggests looking at the total cost and APR, not just the monthly payment. Choose the shortest term whose payment fits comfortably in your budget.

Why longer terms carry more risk
- More interest. You pay interest for more months, and longer terms often have higher rates.
- Negative equity. Cars lose value. With a long term you pay down the balance more slowly, so you can owe more than the car is worth. That's a problem if the car is totaled or you trade it in (the CFPB warns against rolling negative equity into a new loan).
- Repairs during the loan. On a long loan you may still be making payments when bigger maintenance bills arrive.
How to choose
Start with a budget for the total monthly cost of owning the car (payment, insurance, fuel, maintenance). Then compare total cost across terms in the auto loan calculator. If only a very long term makes the payment work, consider a less expensive car or a bigger down payment.
Frequently asked questions
Is a 72-month car loan a bad idea?
Not always, but it usually costs more in total interest and raises the risk of negative equity. Compare total cost with shorter terms first.
Does a longer loan have a higher rate?
Often. Lenders commonly price longer terms higher. Ask for quotes at several terms.
What is negative equity?
Owing more on the loan than the car is worth. The CFPB warns that rolling it into a new loan makes the new loan bigger and more expensive.
