Estimate the real monthly cost of a mortgage.
Start with the home price, down payment, rate and term, then add property tax, homeowners insurance, HOA dues and estimated PMI to see a more complete monthly housing payment.
PMI is included only when the down payment is below 20%. Property tax, insurance, HOA dues and PMI are estimates you control. This calculator does not include closing costs, mortgage points, utilities, maintenance, tax deductions or future changes in taxes and insurance.
Calculator logic reviewed September 9, 2026. The default interest rate is illustrative and is not a current mortgage offer.
Principal and interest
The loan payment uses the standard fixed-rate amortization formula. A 0% rate is handled as equal principal payments over the term.
Housing costs beyond the loan
Taxes, insurance and HOA dues can materially change the monthly cost, so they are included separately instead of being hidden inside one number.
PMI is an estimate
The calculator applies the PMI rate only when the down payment is below 20%. Actual mortgage-insurance rules and cancellation timing depend on the loan.
