Understand Mortgage Payments

Calculate your estimated monthly payment, including principal, interest, taxes, and home insurance (PITI) for purchasing a home.

Mortgage payment formula

For a fixed-rate loan with monthly payments, the principal-and-interest payment is calculated from the principal, monthly rate, and number of monthly payments. A longer term often lowers the monthly payment but can increase total interest.

This estimate may exclude property taxes, homeowners insurance, mortgage insurance, lender fees, escrow charges, and variable-rate changes. Confirm all costs and terms with the lender.
