Choosing an auto loan length is one of the biggest decisions in financing a car, and it is easy to focus only on the monthly payment. Stretching a loan from 36 to 60 or 72 months can make a car feel more affordable each month, but it usually means paying more interest overall and owing more than the car is worth for a longer stretch.
This guide compares 36-, 60- and 72-month terms using a hypothetical example, explains what the Consumer Financial Protection Bureau (CFPB) says about longer loans, and offers a simple checklist for picking a term that fits your budget without overpaying.
Why Loan Length Matters
Your loan term is the number of months you have to repay. The CFPB explains that a shorter loan generally lowers the total cost, while a longer loan lowers the monthly payment but increases the interest you pay. A longer loan can also keep you “upside down,” meaning you owe more than the vehicle is worth, for a longer period.
Longer terms have become common. In the Federal Reserve’s G.19 consumer credit release, the average maturity of new car loans from finance companies was 67 months in June 2026, with an average amount financed of $41,705. The same release reported an average rate of 7.14% on 60-month new car loans from commercial banks in May 2026.
36 vs. 60 vs. 72 Months: Total Cost Comparison (Hypothetical)
To isolate the effect of term length, the table below assumes a $30,000 amount financed at the same 7% APR for every term. In real life, lenders often charge higher rates on longer terms, which would widen the gap. All figures are hypothetical and rounded.
| Loan term | Monthly payment | Total paid | Total interest | Balance after 36 months |
|---|---|---|---|---|
| 36 months | $926.31 | $33,347 | $3,347 | $0 |
| 60 months | $594.04 | $35,642 | $5,642 | $13,268 |
| 72 months | $511.47 | $36,826 | $6,826 | $16,565 |
Moving from 36 to 72 months lowers the monthly payment by about $415 but more than doubles the total interest, from about $3,347 to about $6,826. After three years, the 36-month borrower owns the car outright, while the 72-month borrower still owes about $16,565.
If the longer loan also has a higher rate
Suppose the 72-month loan carried a 7.5% APR instead of 7%. The payment would be about $518.70, and total interest would rise to about $7,347. Even a half-point difference adds about $520 over the life of the loan in this example.
The Case for a 36-Month Loan
- Lowest total interest: Fewer months of interest means a lower overall cost.
- Faster equity: You pay down the balance quickly, reducing the risk of owing more than the car is worth.
- Freedom sooner: Once the loan is paid, that money is available for savings or other goals.
The trade-off is a much higher monthly payment. If a 36-month payment would strain your budget or leave no room for emergencies, it may not be the right fit, even though it is cheapest on paper.
The Case for a 60-Month Loan
A 60-month term is a middle ground. In the example above, it cuts the monthly payment by about $332 compared with 36 months while keeping total interest well below the 72-month option. It is also the standard term the Federal Reserve uses when reporting average commercial bank new car loan rates. For many buyers, a 60-month loan balances affordability with total cost, but it still leaves a meaningful balance after three years.
The Risks of a 72-Month (or Longer) Loan
A 72-month loan offers the lowest payment of the three, but it comes with real risks:
- More interest: You pay interest for twice as long as a 36-month loan.
- Longer negative equity: Cars lose value over time. If you need to sell or trade in early, or if the car is totaled, you may owe more than it is worth.
- Repairs while still paying: By years five and six, the car may need bigger repairs while you are still making loan payments.
- Higher default risk: A 2017 CFPB report found that loans of six years or longer had default rates above 8%, compared with closer to 4% for shorter loans. The report also found these borrowers tended to have lower credit scores and finance larger amounts.
The CFPB’s own illustration makes the point: on a $20,000 loan at 4.75%, a three-year term costs about $597 a month with roughly $1,498 in total interest, while a six-year term costs about $320 a month with roughly $3,024 in interest.
How to Choose the Right Loan Length
- Start with your budget, not the car. The CFPB suggests mapping out your monthly income and expenses first to see what you can comfortably afford.
- Count the full cost of ownership. Add insurance, fuel, maintenance, registration and taxes to the loan payment.
- Get preapproved. The CFPB recommends comparing quotes from several lenders and considering preapproval from a bank or credit union before visiting a dealer. Our guide on how to compare loan offers walks through the process.
- Compare total cost across terms. Ask each lender for the payment and total interest at 36, 48, 60 and 72 months.
- Consider a larger down payment. Putting more down reduces the amount financed and may let you choose a shorter term with a manageable payment.
- Check for prepayment penalties. If you choose a longer term for flexibility, make sure you can pay extra or pay off early without a fee.
- Watch optional add-ons. Extended warranties, GAP coverage and credit insurance are optional and negotiable. They increase the amount you borrow and your payment.
How Your Credit Affects the Rate and Term
Your credit history influences the interest rate lenders offer, and a higher rate makes every term more expensive. If your credit is limited or damaged, it may be worth improving it before buying, or choosing a less expensive car rather than stretching the term to make the payment fit. Our article on bad credit car loans explains how those loans typically work, and our guide to understanding loan interest rates covers how rates are set.
Frequently Asked Questions
Is a 72-month car loan always a bad idea?
Not always, but it usually costs more in interest and leaves you owing more than the car’s value for longer. If you choose one, try to make extra payments toward principal when you can and avoid rolling negative equity into a future loan.
Can I refinance to a shorter term later?
Refinancing may be possible if rates drop or your credit improves, but terms vary by lender and you may face fees. Compare the total cost of the new loan with what you would pay by keeping the current one.
Should I take a longer term and just pay extra each month?
This can provide flexibility if there is no prepayment penalty, but it relies on discipline. If you are confident you can pay extra, you may be better off choosing a shorter term with a slightly higher required payment.
What is a good rule for the payment amount?
There is no official rule. The CFPB recommends focusing on the total cost of the loan and what fits your overall budget rather than any single monthly target.
Bottom Line
A shorter auto loan length costs less overall and builds equity faster, while a longer term lowers the monthly payment at the price of more interest and more time owing more than the car is worth. In our hypothetical $30,000 example, a 72-month loan cost about $3,479 more in interest than a 36-month loan at the same rate. Choose the shortest term whose payment fits comfortably in your budget, and compare total cost, not just the monthly figure.
