Mortgage Rate Calculator 15 Year Fixed

This mortgage rate calculator helps you determine your monthly payments for a 15-year fixed mortgage. By entering your loan amount, interest rate, and other details, you can quickly see how much you'll pay each month and the total interest over the life of the loan.

How the 15-Year Fixed Mortgage Calculator Works

A 15-year fixed mortgage is a home loan with a fixed interest rate for 15 years. This type of mortgage offers lower monthly payments compared to a 30-year mortgage, but the total interest paid over the life of the loan is higher.

The calculator uses the standard mortgage payment formula to determine your monthly payments. This formula takes into account your loan amount, interest rate, and loan term to calculate the fixed monthly payment.

Mortgage Payment Formula

The formula for calculating monthly mortgage payments is:

M = P [ i(1 + i)ⁿ ] / [ (1 + i)ⁿ - 1]

Where:

M = Monthly payment
P = Principal loan amount
i = Monthly interest rate (annual rate divided by 12)
n = Number of payments (loan term in years multiplied by 12)

For a 15-year fixed mortgage, the loan term is 180 months (15 years × 12 months). The calculator uses this fixed term to determine your monthly payments.

How to Use the Calculator

Using the mortgage rate calculator is simple. Follow these steps:

Enter the loan amount you're requesting.
Input the current interest rate for your mortgage.
Click the "Calculate" button to see your monthly payment and total interest.

The calculator will display your estimated monthly payment and the total interest you'll pay over the 15-year term.
