Formula Used

The calculation uses the standard auto loan payment formula:

This formula accounts for the interest on the unpaid balance each month, which is why the monthly payment increases over time.

Worked Example

Let's calculate a $20,000 loan at 4.5% annual interest for 4 years (48 months):

1. Convert annual rate to monthly: 4.5% ÷ 12 = 0.375% or 0.00375
2. Plug values into formula: M = $20,000 [ 0.00375(1 + 0.00375)^48 ] / [ (1 + 0.00375)^48 - 1 ]
3. Calculate numerator: 0.00375 × 1.00375^48 ≈ 0.2166
4. Calculate denominator: 1.00375^48 - 1 ≈ 0.2166
5. Final calculation: $20,000 × (0.2166 / 0.2166) ≈ $433.33

Your monthly payment would be approximately $433.33, with a total interest of $1,933.33 over 4 years.
