Worked Example

Let's calculate a $25,000 auto loan with a 4.5% annual interest rate 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 = $25,000 [ 0.00375(1 + 0.00375)^60 ] / [ (1 + 0.00375)^60 - 1 ] ≈ $25,000 [ 0.00375 × 1.2456 ] / [ 1.2456 - 1 ] ≈ $25,000 × 0.00464 / 0.2456 ≈ $464.00
4. Total paid = $464 × 60 = $27,840
5. Total interest = $27,840 - $25,000 = $2,840

This example shows you would pay approximately $464 per month with a total interest cost of $2,840 over the loan term.
