About Mortgage Calculator
The Mortgage Calculator estimates your monthly home loan payment from four simple inputs: home price, down payment, annual interest rate, and loan term in years. It subtracts your down payment to find the loan amount, then applies standard amortization to show your monthly payment, total interest, and total amount paid over the life of the loan.
It's completely free and runs entirely in your browser. Numbers update live as you type, nothing is uploaded to a server, and no sign-up is required.

- Is this mortgage calculator free to use?
- Yes, it is 100% free with no sign-up, account, or hidden fees. Use it as many times as you like.
