Auto Loan Calculator
Estimate your monthly car payment, total interest, and payoff date in seconds. Adjust the vehicle price, down payment, trade-in, sales tax, term, and APR to see how each factor changes your loan.
Auto loan calculators turn vehicle price, down payment, trade-in equity, sales tax, and APR into a real monthly figure you can budget around. According to Experian's Q4 2025 State of the Automotive Finance Market, the average new car loan reached $43,582 at 6.37% APR — roughly $767 a month, up $21 year-over-year.
bolt Quick Answer
An auto loan calculator estimates your monthly car payment using six inputs: vehicle price, down payment, trade-in value, sales tax, loan term, and APR. The Q4 2025 US average is $767/month for a new car ($43,582 financed at 6.37% APR) and $537/month for a used car ($27,528 at 11.26%), per Experian's latest report.

How an Auto Loan Calculator Works
An auto loan calculator applies the same standard amortization formula that lenders use internally. It starts with your total loan amount — vehicle price plus sales tax and dealer fees, minus your down payment and trade-in equity — then divides that figure into equal monthly payments using your APR and loan term. Each payment is split between interest and principal.
Early payments are mostly interest because the outstanding balance is large. As you pay down principal, the interest portion shrinks and more of every dollar goes toward equity in the vehicle. Understanding this front-loaded structure is why financial planners recommend using a calculator before signing — small changes in term length or APR can swing total interest by thousands of dollars.
By the Numbers
In Q4 2025, the average new car payment hit $767/month (up $21 YoY) and used car $537/month, per Experian. Nearly 30% of new car buyers now stretch into 73–84 month loan terms, and the subprime market share rose from 5.74% to 6.61% year-over-year.
Average Auto Loan APR by Credit Score (Q4 2025)
Your credit score is the single biggest driver of your APR — and therefore your total interest paid. The table below shows average rates by FICO tier from Experian's Q4 2025 State of the Automotive Finance Market. The spread is dramatic: super-prime borrowers locked in 4.66% on new cars, while deep-subprime buyers paid 16.01% — a difference of more than $5,000 in interest on a $30,000 60-month loan.
| Credit Tier | New Car APR | Used Car APR |
|---|---|---|
| Super Prime (781–850) | 4.66% | 6.92% |
| Prime (661–780) | 6.20% | 9.10% |
| Near Prime (601–660) | 9.45% | 13.65% |
| Subprime (501–600) | 12.95% | 18.50% |
| Deep Subprime (300–500) | 16.01% | 21.58% |

Five Ways to Lower Your Monthly Car Payment
If your calculated payment feels too high, you don't have to give up the vehicle — you can adjust the variables that drive the math. Each lever has a different impact on total interest and time-to-payoff. Run the numbers in the calculator above to see which combination works for your budget.
These are the most effective strategies, ranked by impact for the average US borrower in 2026:
- chevron_right Increase your down payment — every extra $1,000 down typically lowers your monthly payment by $18–$22 on a 60-month loan.
- chevron_right Improve your credit score — moving from near-prime to prime can drop your APR 3+ points, saving $40–$60 per month on a $30K loan.
- chevron_right Choose a less expensive vehicle — dropping your target by $5,000 cuts the typical payment by about $90/month at 7% APR over 60 months.
- chevron_right Shop multiple lenders — banks, credit unions, and online lenders can vary by 2–4 points on the same application; pre-qualifying takes minutes.
Avoid the temptation to stretch the term beyond 72 months. While it lowers the monthly payment, you'll likely owe more than the car is worth for most of the loan — a position known as negative equity or being "underwater." As of Q4 2025, roughly 24.9% of trade-ins on new car purchases carry negative equity, averaging $6,754 owed beyond market value — a record high.
Auto Loan Calculator FAQs
How is my monthly car payment calculated? expand_more
Your monthly auto payment is based on the loan amount (vehicle price plus sales tax and fees, minus your down payment and trade-in equity), the annual percentage rate (APR), and the loan term in months. Lenders use the standard amortization formula, which front-loads interest in the early payments and shifts more toward principal as the loan matures.
What is a good APR for an auto loan in 2026? expand_more
According to Experian's Q4 2025 State of the Automotive Finance Market (released February 2026), the average APR for a new car loan was 6.37%, while used car loans averaged 11.26%. Borrowers with super-prime credit scores (781+) qualified for rates as low as 4.66% on new vehicles, while deep-subprime borrowers (300–500) paid an average of 16.01%.
How much should I put down on a car? expand_more
Most financial advisors recommend a down payment of at least 20% on a new car and 10% on a used car. A larger down payment reduces your loan amount, lowers your monthly payment, decreases total interest paid, and helps you avoid being upside-down on the loan if the vehicle depreciates faster than you pay it off.
Does trading in my old car lower the loan amount? expand_more
Yes. Your trade-in value is applied directly to the purchase price, reducing the amount you need to finance. In most states, the trade-in value also reduces the taxable amount, lowering your sales tax bill. If you still owe money on the trade-in, only the equity (trade value minus payoff balance) reduces your new loan amount.
Should I choose a 60-month or 72-month auto loan? expand_more
Shorter loan terms mean higher monthly payments but significantly less total interest. A 60-month loan typically saves $1,500 to $3,000 in interest compared to a 72-month loan on a $30,000 vehicle. Longer terms also increase the risk of negative equity. Choose the shortest term you can comfortably afford within your monthly budget.
