Methodology
What this mortgage calculator includes
The principal-and-interest amount uses the standard fixed-rate amortization formula. The estimated total adds one-twelfth of annual property taxes and homeowners insurance, plus monthly HOA fees and an editable mortgage-insurance estimate when the loan-to-value ratio is above 80%.
The Consumer Financial Protection Bureau explains that a total monthly mortgage payment commonly includes principal, interest, taxes, homeowners insurance, and mortgage insurance when applicable. HOA or condo fees are often paid separately, but they still affect the monthly housing budget.
