Worked Example

Let's calculate a monthly payment for a $25,000 loan with a 4.5% annual interest rate over 5 years:

1. Convert annual rate to monthly: 4.5% ÷ 12 = 0.375% or 0.00375 in decimal
2. Calculate number of payments: 5 years × 12 = 60 payments
3. Plug values into formula: M = $25,000 [ 0.00375(1 + 0.00375)^60 ] / [ (1 + 0.00375)^60 - 1 ]
4. Calculate the result: $25,000 × 0.00567 ≈ $459.25 per month

This example shows that with these terms, your monthly payment would be approximately $459.25, with a total interest cost of about $1,725 over the life of the loan.
