Nerdwallet Loan Calculator Auto

This auto loan calculator helps you estimate monthly payments, total interest, and loan costs. Compare different loan terms and interest rates to find the best financing option for your vehicle purchase.

How to Use This Calculator

Enter the loan amount, interest rate, and loan term in years to calculate your estimated monthly payment. The calculator will show you the total interest paid over the life of the loan and the total cost of the loan.

You can adjust the inputs to see how changes in interest rates or loan terms affect your monthly payments. This helps you make informed decisions when comparing different auto loan offers.

Formula Used

The calculator uses the standard auto loan payment formula:

Monthly Payment = P * (r(1 + r)^n) / ((1 + r)^n - 1) Where: P = Principal loan amount r = Monthly interest rate (annual rate / 12) n = Number of payments (loan term in years * 12)

This formula calculates the fixed monthly payment required to pay off the loan in the specified term.

Worked Example

Let's calculate a monthly payment for a $25,000 loan with a 4.5% annual interest rate over 5 years:

Monthly Payment = $25,000 * (0.045/12 * (1 + 0.045/12)^60) / ((1 + 0.045/12)^60 - 1) Monthly Payment ≈ $472.84

This means you would pay approximately $472.84 per month for 60 months, with a total interest of $3,570.40.
