Formula Used

This 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
i = Monthly interest rate (annual rate divided by 12)
n = Number of payments (loan term in years × 12)

This formula calculates the fixed monthly payment for a loan with a fixed interest rate.

Worked Example

Let's calculate a $25,000 auto loan with a 4.5% APR over 5 years:

  1. Monthly interest rate = 4.5% ÷ 12 = 0.375% or 0.00375
  2. Number of payments = 5 × 12 = 60
  3. Using the formula: M = 25000 [ 0.00375(1.00375)^60 ] / [ (1.00375)^60 - 1 ]
  4. Calculating the numerator: 0.00375 × (1.00375)^60 ≈ 0.2713
  5. Calculating the denominator: (1.00375)^60 ≈ 2.0071
  6. Final calculation: M = 25000 × (0.2713 / 1.0071) ≈ $478.50

Your monthly payment would be approximately $478.50, with a total interest of about $3,500 over the loan term.
