How to Use This Calculator

To use the car loan calculator:

  1. Enter the total loan amount you're borrowing (e.g., $25,000)
  2. Input the annual percentage rate (APR) offered by the lender (e.g., 5.5%)
  3. Select the loan term in years (e.g., 5 years)
  4. Click "Calculate" to see your monthly payment, total interest, and total cost

The calculator uses the standard amortization formula to determine your monthly payments. You can also view a breakdown of your loan payments in the chart below.

Formula Explained

The monthly payment for a car loan is calculated using the following formula:

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

Where:

  • P = Principal loan amount
  • r = Monthly interest rate (APR/12/100)
  • n = Number of payments (Loan Term × 12)

This formula accounts for the interest you'll pay over the life of the loan. The calculator also shows the total interest paid and the total cost of the loan, which includes both the principal and interest.

Worked Example

Let's calculate a car loan with these parameters:

  • Loan Amount: $25,000
  • APR: 5.5%
  • Loan Term: 5 years

Using the formula:

Monthly Payment = $25,000 × [0.004583(1 + 0.004583)60] / [(1 + 0.004583)60 - 1]

Monthly Payment ≈ $452.34

Over 5 years, you would pay approximately $27,140 in total, with $2,140 going to interest.
