Reviewed by Calculator Editorial Team

Use this auto loan payment calculator to estimate your monthly car loan payment. Simply enter your loan amount, interest rate, and loan term to see your estimated payment, total interest paid, and loan breakdown.

How to Use This Calculator

To calculate your auto loan payment:

  1. Enter the loan amount (the total price of the car).
  2. Enter the annual interest rate (APR).
  3. Select the loan term in years.
  4. Click "Calculate" to see your estimated monthly payment.

The calculator will display your monthly payment, total interest paid over the life of the loan, and a breakdown of principal and interest payments.

Formula Explained

The auto loan payment is calculated using the standard loan payment formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ] Where: M = Monthly payment P = Principal loan amount i = Monthly interest rate (APR/12/100) n = Number of payments (loan term in years × 12)

This formula calculates the fixed monthly payment required to pay off a loan with a fixed interest rate over a specified term.

Worked Example

Let's calculate the monthly payment for a $25,000 car loan with a 5% APR over 5 years:

  1. Principal (P) = $25,000
  2. Annual interest rate = 5% → Monthly interest rate (i) = 5%/12 = 0.4167%
  3. Loan term = 5 years → Number of payments (n) = 5 × 12 = 60

Plugging these values into the formula:

M = 25000 [ 0.004167(1 + 0.004167)^60 ] / [ (1 + 0.004167)^60 - 1 ] M ≈ $456.23

So, the estimated monthly payment would be $456.23.

Frequently Asked Questions

What is an APR?

APR stands for Annual Percentage Rate. It's the annual interest rate charged on your loan, expressed as a percentage.

How does a longer loan term affect my payment?

A longer loan term means more monthly payments, but each payment will be smaller. However, you'll pay more in total interest over the life of the loan.

Can I pay extra toward my loan?

Yes, paying extra toward your loan can help you pay it off faster and save on interest. Many lenders allow extra payments without penalty.
