Frequently asked questions

Is Mortgage Calculator free to use?

Yes. Mortgage Calculator is completely free, with no sign-up, no daily limit, and no watermark on what you download.

How is the monthly mortgage payment calculated?

Principal and interest use the standard amortization formula M = P × r(1+r)^n / ((1+r)^n − 1), where P is the loan amount, r is the monthly interest rate and n is the number of payments. Yearly property tax and home insurance are divided by 12 and added to the monthly total.

Does the calculator include property taxes and insurance?

Yes — enter your yearly property tax and home insurance and they are added to the monthly payment. PMI, HOA dues and maintenance are not included, so treat the result as an estimate and confirm exact figures with your lender.
