What Is a 15-Year Fixed Mortgage?

A 15-year fixed mortgage is a home loan that:

  • Has a fixed interest rate for the entire 15-year term.
  • Requires monthly payments that remain consistent over the life of the loan.
  • Typically has lower interest rates than a 30-year mortgage.
  • Allows borrowers to pay off their home faster and reduce overall interest costs.

Unlike adjustable-rate mortgages (ARMs), fixed-rate mortgages provide stability and predictability. This makes budgeting simpler and protects homeowners from interest rate fluctuations.

How the Mortgage Calculator Works

Our mortgage calculator uses the standard formula for calculating monthly payments on a fixed-rate mortgage:M=P×r(1+r)n(1+r)n−1M = P \times \frac{r(1+r)^n}{(1+r)^n - 1}M=P×(1+r)n−1r(1+r)n​

Where:

  • M = monthly payment
  • P = principal loan amount
  • r = monthly interest rate (annual rate ÷ 12)
  • n = total number of monthly payments (15 years × 12 months = 180 payments)

The calculator also provides the total payment over the loan term, helping you understand the full financial commitment.

How to Use the Mortgage Calculator

Using the calculator is quick and simple:

Step 1: Enter Loan Amount

Input the total mortgage amount you plan to borrow.

Example: $250,000

Step 2: Enter Annual Interest Rate

Example Calculation

Suppose you want to borrow $200,000 at an annual interest rate of 5%.

  • Monthly interest rate = 5 ÷ 12 ÷ 100 = 0.004167
  • Number of payments = 15 × 12 = 180

MonthlyPayment=200,000×0.004167×(1+0.004167)180(1+0.004167)180−1≈1,581.59Monthly Payment = \frac{200,000 \times 0.004167 \times (1 + 0.004167)^{180}}{(1 + 0.004167)^{180} - 1} \approx 1,581.59MonthlyPayment=(1+0.004167)180−1200,000×0.004167×(1+0.004167)180​≈1,581.59 TotalPayment=1,581.59×180=284,686.20Total Payment = 1,581.59 \times 180 = 284,686.20TotalPayment=1,581.59×180=284,686.20

This means you will pay approximately $1,582 per month and $284,686 in total over 15 years.
