Use our free mortgage calculator to estimate your monthly mortgage payment, including principal, interest, property tax, and insurance. Whether you're buying your first home or refinancing an existing loan, this tool helps you understand exactly what you'll owe each month, so you can budget with confidence before you commit.

How the Mortgage Calculator Works

Your monthly mortgage payment is calculated using the loan amount, interest rate, and loan term. The core formula used 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 ÷ 12), and n = total number of monthly payments (loan term in years × 12). Many homeowners also add estimated property taxes, homeowners insurance, and PMI to get a complete monthly cost.

Frequently Asked Questions

What's included in my mortgage payment?

A typical mortgage payment includes principal, interest, property taxes, and homeowners insurance (often referred to as PITI). If your down payment is under 20%, PMI may also be added.

How does my down payment affect my monthly payment?

A larger down payment reduces your loan principal, which lowers both your monthly payment and the total interest paid over the life of the loan.

Should I choose a 15-year or 30-year mortgage?

A 15-year mortgage typically has a lower interest rate and builds equity faster, but comes with a higher monthly payment. A 30-year mortgage offers lower monthly payments but costs more in total interest over time.

Does this calculator account for property tax and insurance?

Yes, if you input estimated annual property tax and insurance costs, the calculator factors them into your total monthly payment.
