Reviewed by Calculator Editorial Team

This auto loan calculator helps you estimate monthly payments, total interest costs, and loan affordability. Simply enter your loan amount, interest rate, and loan term to get an instant calculation.

How to Use This Calculator

Using this auto loan calculator is simple:

  1. Enter the loan amount you're considering (e.g., $25,000)
  2. Input the annual interest rate (e.g., 4.5%)
  3. Specify the loan term in years (e.g., 5 years)
  4. Click "Calculate" to see your estimated monthly payment

The calculator will show you the monthly payment amount, total interest paid over the life of the loan, and the total amount repaid.

Formula Used

The calculation uses the standard auto loan payment formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ] Where: M = Monthly payment P = Loan principal i = Monthly interest rate (annual rate / 12) n = Number of payments (loan term in years × 12)

This formula accounts for the fact that each payment includes both principal and interest, with the interest portion decreasing over time as the principal balance is reduced.

Worked Example

Let's calculate a $25,000 loan at 4.5% annual interest for 5 years:

  1. Convert annual rate to monthly: 4.5% ÷ 12 = 0.375% or 0.00375
  2. Calculate number of payments: 5 years × 12 = 60 payments
  3. Plug into formula: M = 25000 [ 0.00375(1 + 0.00375)^60 ] / [ (1 + 0.00375)^60 - 1 ] M ≈ $452.34 per month

Over 5 years, you would pay approximately $27,140.40 in total, with $2,140.40 going to interest.

Interpreting Results

When using this calculator, consider these factors:

  • Monthly payment: This is your fixed payment each month
  • Total interest: Shows how much extra you'll pay beyond the loan amount
  • Total repayment: The sum of principal and interest

Remember that these are estimates. Actual payments may vary based on your lender's specific terms and any additional fees.
