Formula Used

The monthly payment for a 15-year mortgage is calculated using the standard mortgage payment formula:

M = P [ r(1 + r)^n ] / [ (1 + r)^n - 1 ] Where: M = Monthly payment P = Principal loan amount r = Monthly interest rate (annual rate divided by 12) n = Number of payments (loan term in years × 12)

This formula accounts for the present value of the loan amount and the interest payments over the life of the loan.

Worked Example

Let's calculate a 15-year mortgage for $200,000 at a 4.5% annual interest rate:

Convert annual rate to monthly: 4.5% ÷ 12 = 0.375% or 0.00375
Calculate number of payments: 15 years × 12 = 180 payments
Apply the formula:
M = 200,000 [ 0.00375(1 + 0.00375)^180 ] / [ (1 + 0.00375)^180 - 1 ] M ≈ $1,204.56

Your estimated monthly payment would be $1,204.56, with a total interest payment of approximately $121,760 over 15 years.

Benefits of a 15-Year Mortgage

A 15-year mortgage offers several advantages:

Lower monthly payments compared to 30-year mortgages
Potential tax benefits from interest deductions
Faster payoff of the loan principal
Opportunity to build equity more quickly

Note: While 15-year mortgages offer lower payments, they typically have higher interest rates than 30-year mortgages. Always compare both options before making a decision.
