The calculator will display your estimated monthly payment, total interest paid, and total amount paid over the life of the loan.

Formula Used

The monthly payment is calculated using the standard auto loan formula:

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

This formula accounts for the interest compounded monthly, which is standard for auto loans.

Worked Example

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

Monthly interest rate = 4.5% / 12 = 0.375% or 0.00375
Number of payments = 5 × 12 = 60
Using the formula: M = $25,000 [ 0.00375(1 + 0.00375)^60 ] / [ (1 + 0.00375)^60 - 1 ] ≈ $452.34 per month

Total interest paid would be $2,720.40, and total amount paid would be $27,720.40.

Note: Actual payments may vary slightly due to rounding and lender-specific calculations.
