How auto loan term length changes what you pay

When you finance a car, the term (how many months you take to repay) is one of the easiest numbers to change and one of the easiest to overlook. A longer term lowers the monthly payment. It also usually means paying more interest overall and owing more on the car for longer.

What the CFPB suggests comparing

The CFPB points out that it's common to focus on the monthly payment, but other factors have more impact on what you pay over the life of the loan. It suggests comparing offers on:

• the amount of the loan,
• the APR and interest rate (see APR vs. interest rate),
• the length of the loan, and
• the monthly payment.

In its own example of a $20,000 loan at 4.75%, the CFPB shows total interest of $1,498 over 36 months compared with $3,024 over 72 months, more than twice as much. Running those same inputs through the formula this site uses gives matching results ($1,498.32 and $3,024.48 total interest).

A worked example (illustration only)

These inputs are hypothetical and are not a current market rate: a $30,000 amount financed at 7% APR, with the same rate across every term. In real life, lenders may charge different rates for different terms, so compare actual quotes.

• 36 months: payment $926.31, total interest $3,347.26
• 48 months: payment $718.39, total interest $4,482.59
• 60 months: payment $594.04, total interest $5,642.16
• 72 months: payment $511.47, total interest $6,825.85
• 84 months: payment $452.78, total interest $8,033.55

Going from 60 to 84 months lowers the payment by $141.26 a month but adds $2,391.39 in interest, even at the same rate.

Longer terms and negative equity

Cars generally lose value over time, and a long loan pays down the balance slowly. The CFPB notes that longer loans are more likely to leave you owing more than the vehicle is worth, which is called negative equity. That matters if you want to sell or trade in the car, or if it is totaled and the insurance payout is less than what you owe.

Here are the remaining balances in the same hypothetical example (illustration only):

• After 24 payments: $19,238.72 on the 60-month loan, $21,359.10 on the 72-month loan, $22,866.31 on the 84-month loan
• After 36 payments: $13,267.85 on the 60-month loan, $16,564.71 on the 72-month loan, $18,908.20 on the 84-month loan

This site does not estimate what the car will be worth. How fast a car loses value depends on the vehicle, its mileage and condition, and the market. Compare these balances with a current resale or trade-in estimate for your specific car.

The CFPB also mentions that some financial experts recommend keeping an auto loan to five years or less. Whether that fits you depends on your budget and the car.

Get the amount financed right

Car loan payments are based on the amount financed, not the sticker price. That amount can include sales tax, title and registration fees, add-on products, and negative equity from a trade-in, and it goes down with your down payment and any trade-in credit. Take the amount financed from your buyer's order or retail installment contract and enter it as the loan amount in the auto loan calculator. If an add-on is optional, try the calculation with and without it to see its real monthly and total cost.

Tips for comparing terms

1. Decide on a monthly budget that includes insurance, fuel, and maintenance, not just the loan payment.
2. Compare the total interest and total paid for each term, not only the payment.
3. Get a rate quote from a bank or credit union before visiting the dealer so you have something to compare against.
4. Make sure the financing is final before you drive away. The CFPB warns about "spot delivery," where a dealer can come back later to renegotiate if the financing isn't finalized.
5. If you pick a longer term for the lower required payment, check whether you can pay extra toward principal without penalty. See extra principal payments.

FAQ

• What is the best auto loan term? There is no single answer. Shorter terms usually cost less in total; longer terms lower the payment. The CFPB notes that some experts suggest five years or less.
• Do longer auto loans have higher rates? They can, depending on the lender. Compare actual quotes for each term rather than assuming the rate stays the same.
• Should I put taxes and fees in the loan amount? If they are financed, yes. Use the amount financed from your contract so the payment estimate is accurate.
• Can I pay off a car loan early? Many loans allow it. Check your contract for any prepayment terms.
