This mortgage calculator helps you estimate your monthly payments for a 15-year fixed-rate mortgage. A 15-year fixed mortgage offers lower interest rates and shorter repayment terms compared to 30-year mortgages, but requires larger monthly payments.
How the 15-Year Fixed Mortgage Calculator Works
A 15-year fixed mortgage calculator estimates your monthly payments based on the loan amount, interest rate, and term length. The calculator uses the standard mortgage formula:
Monthly Payment = P × (r(1+r)^n) / ((1+r)^n - 1)
Where:
- P = Principal loan amount
- r = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in years × 12)
The calculator also provides the total interest paid over the life of the loan and the total amount paid (principal + interest).
Note: This calculator provides estimates only. Your actual mortgage payments may vary based on additional fees, taxes, and lender-specific terms.
How to Use This Calculator
- Enter the loan amount you're seeking (e.g., $200,000)
- Input your current interest rate (e.g., 3.5%)
- Select the loan term (15 years for this calculator)

Example Calculation
Let's calculate a $200,000 mortgage at 3.5% interest for 15 years:
| Loan Amount | $200,000 |
|---|---|
| Interest Rate | 3.5% |
| Loan Term | 15 years |
| Monthly Payment | $1,428.65 |
| Total Interest Paid | $10,855.40 |
| Total Amount Paid | $210,855.40 |
In this example, you would pay $1,428.65 per month, with a total of $10,855.40 in interest over 15 years.
