Mortgage Calculator

Q: How is a monthly mortgage payment calculated?

The principal-and-interest payment uses the standard amortization formula on your loan amount (home price minus down payment), your interest rate, and the number of months in the term. This free calculator adds property tax, home insurance, and HOA to show your full monthly payment (PITI), plus the total interest over the life of the loan.

Q: Does it include taxes and insurance?

Yes. Open Advanced to add annual property tax, annual home insurance, and a monthly HOA fee, and the total monthly payment updates to include them.
