About Mortgage Calculator

Mortgage Calculator is a free tool that shows what a home will really cost you each month. Enter the home price, down payment, interest rate, and term, and it instantly estimates your full monthly payment: not just principal and interest, but property tax, home insurance, PMI, and HOA too.

The whole payment, not just part of it

Most quick calculators only show principal and interest, which understates what you'll actually pay. This tool adds the costs that show up in a real mortgage statement: property taxes, homeowners insurance, PMI (private mortgage insurance), and HOA dues. The result is a realistic monthly number you can budget around.

See where your money goes

A breakdown chart splits your payment into its parts so you can see how much is principal and interest versus taxes, insurance, and fees. You also get your loan amount, total interest over the life of the loan, and the total of all payments.

Full amortization schedule

Open the built-in amortization schedule to see every payment across the life of the loan: how much goes to principal, how much to interest, and the remaining balance each month. It's an easy way to see how equity builds over time.

Down payment and PMI

Enter your down payment as a dollar amount or a percentage; they stay in sync. When your down payment is under 20%, the tool reminds you that PMI is usually required, so your estimate stays realistic.
