Car Loan Calculator

Calculate Your Car Loan Payments Instantly

How This Calculation Works

This calculator estimates your monthly car payment using a widely accepted loan amortization method. It considers the total financed amount (vehicle price after down payment and trade-in, plus taxes), the interest rate, and the loan duration.


Monthly Payment Formula

M = P × [r(1 + r)ⁿ] ÷ [(1 + r)ⁿ – 1]

Where:

  • M = Monthly payment
  • P = Total loan amount (amount financed)
  • r = Monthly interest rate (APR ÷ 12 ÷ 100)
  • n = Loan term in months

How the Result Is Calculated

  • Sales tax is calculated and added to the vehicle price
  • Down payment and trade-in value are subtracted to determine the loan amount
  • The annual interest rate is converted into a monthly rate
  • The formula is applied to estimate your monthly payment
  • Total payment is calculated over the full loan term
  • Total interest is determined by subtracting the principal from total payments
