How the mortgage calculator works

Estimate a monthly mortgage payment including principal, interest, property tax, and insurance.

Formula

Principal and interest use the fixed-rate amortization formula. Estimated monthly tax and insurance are added separately.

Example

A $400,000 home with 20% down creates a $320,000 principal balance before estimated taxes and insurance.

What affects the result

  • The down payment changes the loan principal.
  • Small rate differences can materially affect long-term interest.
  • Taxes, insurance, HOA dues, and mortgage insurance may change the full housing cost.

Frequently asked questions

Does this include PMI?

Not currently. Add expected mortgage insurance to your budget separately when your loan requires it.

Are property taxes exact?

No. They are an estimate based on the annual amount you enter.
