Mortgage 15 Year Calculator

Use our mortgage 15 year calculator to determine your monthly payments, total interest, and principal repayment for a 15-year mortgage. This tool helps you understand the financial commitment of a 15-year loan compared to longer-term mortgages.

How the 15-Year Mortgage Calculator Works

A 15-year mortgage is a home loan that is repaid over 15 years with fixed monthly payments. The calculator uses the standard mortgage formula to determine your payments based on the loan amount, interest rate, and term.

Mortgage Formula

The monthly payment (P) is calculated using the formula:

P = L × [r(1 + r)^n] / [(1 + r)^n - 1]

Where:

L = Loan amount
r = Monthly interest rate (annual rate ÷ 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 repaid, which includes both principal and interest.

How to Use the Mortgage Calculator

Enter the loan amount you're considering.
Input the annual interest rate (APR).
Select the loan term (15 years for this calculator).
Click "Calculate" to see your monthly payment, total interest, and total repayment.
Review the amortization chart to see how your loan is paid off over time.

Note: This calculator assumes a fixed interest rate and does not account for prepayment penalties or other fees that might apply to your specific mortgage.

Example Calculation

Let's say you're considering a $200,000 mortgage with a 4% annual interest rate over 15 years.

Example Inputs

Loan amount: $200,000
Annual interest rate: 4%
Loan term: 15 years

The calculator would determine:

Monthly payment: $1,374.56
Total interest paid: $102,186.80
Total repayment: $302,186.80

This means you would pay $1,374.56 each month for 15 years, with $102,186.80 going toward interest and $200,000 going toward the principal.
