Calculate monthly car payment
Use the full option form below to estimate financed amount, monthly payment, interest, payoff time, and total ownership cash outlay.
Formula used
The standard installment loan payment formula estimates the base monthly payment for a fixed-rate auto loan.
Where:
- M = monthly payment
- P = amount financed
- r = monthly interest rate = APR ÷ 12
- n = total number of monthly payments
This page also adjusts the financed balance using down payment, trade-in value, rebate, taxes, and fees.
If APR is zero, the calculator divides the financed amount evenly across the selected term.

Frequently asked questions
1. What is a monthly car payment?
A monthly car payment is the fixed amount you pay each month toward an auto loan. It usually includes principal and interest, and sometimes financed taxes or fees.
2. How does a down payment affect my payment?
A larger down payment lowers the amount financed. That usually reduces your monthly payment, total interest paid, and overall loan cost.
3. Does a longer loan term lower the payment?
Yes. Spreading the balance over more months usually lowers the payment. However, longer terms often increase total interest and keep you in debt longer.
4. Should I finance taxes and fees?
Financing taxes and fees reduces upfront cash needed, but it increases the loan balance. That can raise both monthly payment and total interest.
5. What does APR mean?
APR means annual percentage rate. It reflects the yearly borrowing cost and is used to calculate the monthly interest portion of each payment.
6. Can extra monthly payments help?
Yes. Extra payments usually reduce the principal faster, shorten the payoff period, and lower total interest over the life of the loan.
7. How does trade-in value change financing?
A trade-in lowers the amount you need to borrow. In many cases it may also reduce the taxable amount, depending on local rules.
8. Are these results exact lender quotes?
No. This calculator provides estimates. Actual offers depend on credit profile, lender policies, location, taxes, fees, and any promotional financing terms.
