How to calculate your auto loan payment

Use this auto loan calculator to estimate your monthly car payment before visiting a dealership. Enter your vehicle price, down payment, trade-in value, interest rate, loan term, taxes, and fees to see your estimated monthly payment, total loan cost, and payoff date instantly.

How an auto loan payment is calculated

Your monthly auto loan payment depends on three main factors: the amount financed, your interest rate, and your loan term. The amount financed is your vehicle price plus taxes and fees, minus your down payment and trade-in value. Higher interest rates and longer loan terms usually increase the total amount you pay over time.

What is included in your auto loan estimate

This calculator includes more than just the vehicle sticker price. It factors in sales tax, dealer fees, and other costs, then subtracts your down payment and trade-in value so you can see a more realistic estimate of what you may actually finance.

How to lower your monthly auto loan payment

  • Increase your down payment to reduce the amount financed.
  • Improve your credit score to qualify for a lower APR.
  • Compare lenders before financing through a dealership.
  • Choose a shorter term if you want to pay less interest overall.
  • Negotiate the vehicle price before discussing financing.

Auto loan term: how long should you finance a car

Many borrowers choose loan terms between 36 and 60 months. Longer terms can reduce your monthly payment, but they usually increase total interest and can leave you owing more than the car is worth for longer. Use the term options in the calculator above to compare the monthly payment difference.

New vs. used car loan rates

New car loans often come with lower interest rates because lenders see them as less risky. Used car loans may have slightly higher APRs, but the lower purchase price can still make them the better overall option. This calculator helps you compare both scenarios by adjusting price, rate, and loan term.

Use this auto loan calculator before you finance

Auto loan calculator FAQ

Enter your vehicle price, down payment, trade-in value, interest rate, loan term, sales tax, and dealer fees into the auto loan calculator above. It instantly estimates your monthly car payment, total interest, total loan cost, and payoff date so you can see the real cost of financing before you buy.
A good car loan interest rate depends on your credit score, the lender, and whether the vehicle is new or used. Buyers with strong credit usually qualify for lower APRs, while borrowers with lower credit scores often pay more. Use this calculator to compare how different interest rates affect your monthly payment and total interest paid.
Many buyers choose auto loan terms between 36 and 60 months. A longer loan term can lower your monthly payment, but it usually increases total interest and may keep you upside down on the loan for longer. This calculator lets you compare 24, 36, 48, 60, and 72 month terms side by side.
A larger down payment lowers the amount you need to finance, which can reduce your monthly car payment and total interest. Many buyers aim for 10% to 20% down, but even a smaller amount can help. Use the down payment field above to see how your estimated payment changes instantly.
Yes. Your credit score can have a major impact on the APR you qualify for, and that directly affects both your monthly payment and total loan cost. Even a small difference in interest rate can add up over the life of the loan, which is why it helps to compare financing scenarios before applying.
It is smart to compare both. Dealer financing can be convenient, but banks and credit unions may offer lower auto loan rates. Getting pre-approved before visiting the dealership can also give you more negotiating power. This calculator helps you compare payment estimates before choosing a lender.
Yes. This auto loan calculator includes fields for sales tax and dealer fees so you can estimate a more realistic monthly payment. Adding these costs helps you avoid underestimating how much you may actually finance compared with looking at the vehicle price alone.
A 72 month car loan is not always bad, but it usually means lower monthly payments and higher total interest. Longer terms can also increase the chance of owing more than the car is worth for a longer period. Use the loan term options above to compare whether the lower payment is worth the added cost.
Yes, a trade-in value can reduce the amount you need to finance, which may lower your monthly car payment and total interest. Enter your trade-in value in the calculator above to see how much it changes your estimated loan amount and monthly payment.
The total interest you pay depends on your loan amount, APR, and loan term. Higher interest rates and longer repayment periods usually increase the total borrowing cost. This calculator shows your estimated total interest automatically so you can compare different financing options before committing.
