Edmunds Auto Payment Calculator

Reviewed by Calculator Editorial Team

Use our Edmunds Auto Payment Calculator to estimate your monthly car payments based on loan amount, interest rate, and loan term. This tool helps you understand your financing options before purchasing a vehicle.

How to Use This Calculator

To calculate your Edmunds auto payment, follow these simple steps:

  1. Enter the vehicle price (the total cost of the car).
  2. Input your down payment (the amount you'll pay upfront).
  3. Specify the loan term (how many years you'll finance the car).
  4. Enter the interest rate (the annual percentage rate for your loan).
  5. Click the Calculate button to see your estimated monthly payment.

The calculator will display your monthly payment, total interest paid, and total amount paid over the life of the loan.

Formula Used

The auto payment calculator uses the standard auto loan payment formula:

Monthly Payment = P * (r(1 + r)^n) / ((1 + r)^n - 1) Where: P = Principal loan amount (Vehicle Price - Down Payment) r = Monthly interest rate (Annual Rate / 12 / 100) n = Number of payments (Loan Term in Years * 12)

This formula calculates the fixed monthly payment for a loan with a fixed interest rate.

Worked Example

Let's calculate the monthly payment for a $30,000 car with a $3,000 down payment, 5-year loan term, and 4.5% annual interest rate.

  1. Principal (P) = $30,000 - $3,000 = $27,000
  2. Monthly interest rate (r) = 4.5% / 12 / 100 = 0.00375
  3. Number of payments (n) = 5 * 12 = 60
  4. Monthly Payment = $27,000 * (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1)
  5. Monthly Payment ≈ $478.50

Using this example, your estimated monthly payment would be $478.50.
