Reviewed by Calculator Editorial Team

This free 6 year auto loan calculator helps you estimate your monthly payments, total interest, and loan affordability. Simply enter your loan amount, interest rate, and down payment to get instant results.

How to Use This Calculator

Using our 6 year auto loan calculator is simple:

  1. Enter the loan amount you're considering (e.g., $25,000)
  2. Input your annual interest rate (e.g., 5.5%)
  3. Specify your down payment amount (if any)
  4. Click "Calculate" to see your estimated monthly payment

The calculator will display your monthly payment, total interest paid over 6 years, and the total amount repaid. You can also view a payment breakdown chart.

Formula Explained

The calculator uses the standard auto loan payment formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ] Where: M = Monthly payment P = Principal loan amount (after down payment) i = Monthly interest rate (annual rate / 12) n = Number of payments (6 years × 12 = 72)

This formula accounts for the interest you'll pay over the life of the loan. The calculator automatically converts your annual interest rate to a monthly rate and calculates the total number of payments.

Worked Example

Let's calculate a $25,000 loan at 5.5% APR with a $5,000 down payment:

  1. Principal after down payment: $25,000 - $5,000 = $20,000
  2. Monthly interest rate: 5.5% ÷ 12 = 0.4583%
  3. Number of payments: 6 × 12 = 72
  4. Using the formula: M = $20,000 [ 0.004583(1.004583)^72 ] / [ (1.004583)^72 - 1 ]
  5. Monthly payment ≈ $342.50
  6. Total interest paid ≈ $2,700
  7. Total amount repaid ≈ $22,700

This example shows you'll pay approximately $342.50 per month with about $2,700 in interest over 6 years.
