Mortgage Calculator

Estimate mortgage payments with tax, insurance, and PMI. See principal, interest, and a yearly amortization breakdown. Private, in-browser, and free.

The Mortgage Calculator estimates a fixed-rate monthly principal-and-interest payment from home price, down payment, rate, and term. Optional extras (taxes, insurance, HOA) help you sketch a fuller monthly housing cost. Soften the numbers until the payment fits your budget — then confirm with a lender. What this calculator estimates A mortgage payment has two core pieces: principal (loan balance) and interest. Many homeowners also pay property tax, homeowners insurance, and sometimes mortgage insurance or HOA dues in the same monthly draft. Simple Calculators focuses on clear inputs: price, down payment (amount or percent), interest rate, and loan term. Advanced fields let you layer taxes and insurance when you want a fuller “all-in” view. How the payment is computed Loan amount = price − down payment. For a fixed-rate fully amortizing loan, the monthly principal-and-interest payment uses the standard annuity formula based on monthly rate and number of months. A lower rate, larger down payment, or shorter term reduces interest paid over the life of the loan — but a shorter term raises the monthly payment.
