Payment Details
What Is a 15-Year Fixed Mortgage?
A 15-year fixed mortgage is a home loan where the interest rate remains constant for the full term of 15 years. Unlike adjustable-rate mortgages (ARMs), your monthly payments remain stable, making it easier to budget.
Key advantages:
- Faster payoff compared to 30-year loans
- Lower total interest payments
- Predictable monthly payments
- Builds equity faster
The main trade-off is higher monthly payments compared to longer-term mortgages, but the long-term savings and security often outweigh this.
How the Mortgage Calculator Works
The calculator uses the standard fixed-rate mortgage formula: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 payments (15 × 12 = 180 months)
This formula accounts for compound interest, ensuring you get an accurate monthly payment and total payment over 15 years.

Example Calculation
Suppose you want to calculate payments for:
- Loan Amount: $300,000
- Interest Rate: 6%
Calculation:
- Convert annual interest to monthly: 6% ÷ 12 = 0.005
- Total payments: 15 × 12 = 180 months
- Monthly payment:
M=300,000(1+0.005)180−10.005(1+0.005)180≈2,531.65
Total payment: 2,531.65 × 180 = $455,697
This means over 15 years, you will pay $455,697 for a $300,000 loan at 6% interest.
