In car sales, the term is the length of your auto loan, expressed in months. It’s the number of monthly payments you agree to make before the car is paid off and the lender releases its lien on the title. Most auto loans run between 36 and 84 months, and the average new-car loan currently sits around 69 months. The term you pick is one of the most consequential numbers in the whole deal because it sets your monthly payment and, together with the interest rate, decides how much the car will actually cost you by the end.
What the Term Governs on Your Contract
The term starts when you sign the financing agreement and ends when you make your final scheduled payment. Federal law requires the lender to disclose the number, amount, and timing of every payment before you sign, so the term should appear clearly on your paperwork.1Consumer Financial Protection Bureau. 12 CFR 1026.17 General Disclosure Requirements That same disclosure has to show the total finance charge, meaning the dollar cost of borrowing.2eCFR. 12 CFR Part 226 – Truth in Lending (Regulation Z) Those two numbers, side by side, are what you need to compare one loan offer against another.
Common Term Lengths
Lenders usually offer terms in 12-month increments. The typical options are 24, 36, 48, 60, 72, and 84 months, and some lenders now stretch as far as 96. Used-car loans tend to run a bit shorter, most often between 36 and 72 months. Some lenders won’t finance a used vehicle at all once it passes roughly 10 years old, and even when they will, they may cap the term below what they’d offer on a new car.
Average term lengths have crept upward with vehicle prices. New-car loans average about 69 months and used-car loans about 67. Longer terms lower the payment, which is why buyers reach for them, but the tradeoff shows up quickly once you look at total cost.
How the Term Changes Your Monthly Payment
Auto loans use amortization. Each payment splits between interest and principal, and the mix shifts as you go: early on, most of the payment covers interest, and only later does the balance start dropping meaningfully.3Consumer Financial Protection Bureau. What Is Amortization and How Could It Affect My Auto Loan?
The CFPB uses a $20,000 loan at 4.75% to show what stretching the term does to the payment:4Consumer Financial Protection Bureau. How Do I Compare Auto Loan Offers?
- 36 months: $597 per month
- 48 months: $458 per month
- 60 months: $375 per month
- 72 months: $320 per month
Doubling the term from 36 to 72 months roughly halves the payment. That’s the appeal. The problem is what the same numbers look like from the other direction.
What You Pay in Total Interest
Here’s the total interest cost on that same $20,000 loan at 4.75%:4Consumer Financial Protection Bureau. How Do I Compare Auto Loan Offers?
- 36 months: $1,498 in interest
- 48 months: $1,999 in interest
- 60 months: $2,508 in interest
- 72 months: $3,024 in interest
The 72-month borrower pays more than double the interest of the 36-month borrower at the same rate. And rates usually aren’t the same. Lenders treat longer loans as riskier and price them higher, so a real 72-month offer typically carries a rate above what you’d get at 48 or 60. Most auto loans use simple interest, meaning charges accrue daily on the remaining principal.5Federal Reserve. Vehicle Leasing: Daily Simple Interest Method A longer term keeps that balance higher for more months, giving interest more time to pile up.
The Negative Equity Problem
New cars lose roughly 50 to 60 percent of their value in the first five years. Because amortization keeps your loan balance high early on, a long term paired with a small down payment can easily leave you owing more than the car is worth for years. That gap is called negative equity.
CFPB data ties negative equity directly to term length. Borrowers who rolled negative equity into their next vehicle purchase averaged 73-month loans with a loan-to-value ratio around 119 percent, meaning they financed roughly 19 percent more than the car was worth at origination. Borrowers without a trade-in averaged 67-month terms and a 102 percent loan-to-value ratio.6Consumer Financial Protection Bureau. Negative Equity in Auto Lending
Being underwater doesn’t matter much until something forces the issue. If the car is totaled, your insurer pays market value, not what you owe. If you need to sell or trade before the loan ends, you cover the shortfall out of pocket. A common workaround is rolling the leftover balance into the next loan, which starts the next car already underwater.
Where GAP Insurance Fits
Guaranteed Asset Protection insurance is built for exactly this situation. It covers the difference between what standard auto insurance pays if the car is totaled or stolen and what you still owe on the loan.7Consumer Financial Protection Bureau. What Is Guaranteed Asset Protection (GAP) Insurance? Whether it’s worth buying depends on how far underwater you’re likely to be. Less than 20 percent down on a new car with a 60-month or longer term usually means a long stretch upside down, and GAP is a cheap hedge in that case. Twenty percent or more down on a shorter loan makes the math weaker, since you may never owe more than the car is worth. Dealers sell GAP at the finance desk, but it’s often less expensive through your own auto insurer.
Changing Your Term After You Sign
Because auto loans use simple interest, extra payments toward principal reduce your balance faster and cut the interest you’ll pay over the life of the loan.5Federal Reserve. Vehicle Leasing: Daily Simple Interest Method Small extra payments early on, when the balance is highest, do the most work.
Check your contract before you pay ahead, though. Some lenders charge a prepayment penalty to recover interest they’d otherwise miss. Whether they can enforce it depends on the contract and on state law, since some states prohibit prepayment penalties on auto loans.8Consumer Financial Protection Bureau. Can I Prepay My Loan at Any Time Without Penalty? Your Truth in Lending disclosure will show whether one applies.
Refinancing is the other lever. If rates have dropped or your credit has improved, refinancing into a shorter term at a lower rate can save on both sides. Refinancing into a longer term does the opposite: the monthly payment drops, but interest keeps accruing over more months, and the total cost usually climbs.
Picking a Term
The CFPB and most financial guides recommend keeping auto loans to five years or shorter. Terms past 60 months are more likely to leave you owing more than the car is worth, and the added interest builds up fast.4Consumer Financial Protection Bureau. How Do I Compare Auto Loan Offers?
The useful move is to shop by total cost rather than by monthly payment. A 72-month loan at a comfortable $320 sounds easy until you notice you’re paying $3,024 in interest instead of $1,498. A larger down payment or a less expensive car can often bring a shorter term into range without wrecking your monthly budget.
Match the term to how long you actually plan to keep the vehicle. An 84-month loan on a car that may need major repairs in year five puts you in the awkward position of making payments on something that’s already costing money to keep running. Line the term up with the years you expect to own the car and you avoid paying interest on a vehicle you no longer want.
