How to Use This Car Payment Calculator

Using the Car Payment Calculator is straightforward. Begin by entering the vehicle price, which is the total cost of the car you wish to purchase. Next, input your down payment and any trade-in value you may have. Then, specify the sales tax rate, the interest rate on your loan, and the loan term in months. Once all fields are filled, click the calculate button to see your estimated monthly payment and other financial details.

The Car Payment Formula

Monthly Payment = [P * r(1 + r)^n] / [(1 + r)^n - 1]

Where:

  • P = Loan amount (vehicle price - down payment - trade-in value)
  • r = Monthly interest rate (annual interest rate / 12)
  • n = Total number of payments (loan term in months)

Example Calculation

Let’s say you want to buy a car priced at $30,000. You plan to make a down payment of $5,000 and have a trade-in worth $2,000. The sales tax rate is 7%, the interest rate on your loan is 5%, and the loan term is 60 months.

First, calculate the financed amount:

  • Financed Amount = Vehicle Price - Down Payment - Trade-in Value
  • Financed Amount = $30,000 - $5,000 - $2,000 = $23,000

Next, calculate the monthly interest rate:

  • Monthly Interest Rate = Annual Interest Rate / 12 = 5% / 12 = 0.004167

Now, plug the values into the formula:

  • Monthly Payment = [23000 * 0.004167(1 + 0.004167)^60] / [(1 + 0.004167)^60 - 1]
  • Monthly Payment ≈ $432.25

After calculating, you will also see the total interest paid and the overall cost of the loan.
