15 Year Mortgage Rates Payment Calculator

This 15-year mortgage payment calculator helps you estimate your monthly payments for a 15-year home loan. Simply enter your loan amount, interest rate, and down payment to see your estimated monthly payment, total interest paid, and amortization schedule.

How the 15-Year Mortgage Calculator Works

A 15-year mortgage is a home loan that's repaid over 15 years instead of the more common 30-year term. This shorter repayment period typically results in lower monthly payments but higher total interest costs compared to a 30-year mortgage.

The calculator uses the standard mortgage payment formula to determine your monthly payment based on:

Loan amount (principal)
Annual interest rate
Loan term (15 years)

Key features of a 15-year mortgage include:

Lower monthly payments than 30-year mortgages
Higher total interest paid over the life of the loan
Faster payoff of the principal balance
Potential tax benefits in some jurisdictions

Note: The calculator provides estimates only. Actual payments may vary based on your lender's specific terms and conditions.

Formula Used

The monthly mortgage payment is calculated using the following formula:

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 × 12)

For a 15-year mortgage, n = 15 × 12 = 180 payments.

Worked Example

Let's calculate a monthly payment for a $200,000 loan with a 4% annual interest rate over 15 years.

Convert annual interest rate to monthly: 4% ÷ 12 = 0.333% or 0.00333
Calculate the number of payments: 15 × 12 = 180
Plug values into the formula:

M = $200,000 [0.00333(1 + 0.00333)¹⁸⁰] / [(1 + 0.00333)¹⁸⁰ - 1]
Calculate the monthly payment: $200,000 × [0.00333 × (1.00333)¹⁸⁰] / [(1.00333)¹⁸⁰ - 1] ≈ $1,382.42

For this example, the monthly payment would be approximately $1,382.42.
