How 15-Year Fixed Mortgages Work

A 15-year fixed mortgage is a home loan with a fixed interest rate for 15 years. This type of mortgage offers several advantages:

Lower monthly payments compared to 30-year mortgages
Potential for lower total interest paid
Faster payoff of your mortgage

The loan amount is calculated by subtracting your down payment from the home's purchase price. The monthly payment is determined by the loan amount, interest rate, and loan term.

Mortgage Payment Formula

Monthly Payment = P * (r(1+r)^n) / ((1+r)^n - 1)

Where:

P = Principal loan amount (loan amount - down payment)
r = Monthly interest rate (annual rate / 12)
n = Number of payments (loan term in years * 12)

With a 15-year fixed mortgage, you'll pay off your loan faster than with a 30-year mortgage, which can help you build equity more quickly and potentially save on interest costs.

Example Calculation

Let's say you're looking to buy a home priced at $300,000 with a 15-year fixed mortgage. You put down 20% ($60,000) and get a 4.5% interest rate.

Your loan amount would be $240,000. Using the formula:

Monthly Payment = $240,000 * (0.00375(1+0.00375)^180) / ((1+0.00375)^180 - 1)

This calculates to approximately $1,820 per month.

Over 15 years, you would pay about $331,200 in total payments, with $91,200 going toward interest.
