Worked Example

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

1. Principal = $25,000 - $5,000 = $20,000
2. Monthly interest rate = 4.5% / 12 = 0.375%
3. Number of payments = 5 × 12 = 60
4. Using the formula: M = $20,000 [ 0.00375(1 + 0.00375)^60 ] / [ (1 + 0.00375)^60 - 1 ]
5. Calculated monthly payment = $382.50
6. Total interest paid = $382.50 × 60 - $20,000 = $1,350

This example shows you would pay approximately $382.50 per month with $1,350 in total interest over the life of the loan.
