Mortgage calculators
Free mortgage calculators: monthly payment with taxes and PMI, affordability by DTI, refinance break-even, rent vs buy, HELOC and closing costs by state.
How the calculators work
Every calculator runs the same amortization engine in your browser, so results update as you move a slider, and the same maths runs on the server so the page still works with JavaScript switched off. Defaults come from the facts table: the interest rate is Freddie Mac’s latest weekly 30-year average, property tax rates come from the US Census Bureau’s American Community Survey, and insurance and PMI defaults use Freddie Mac’s published averages. Each default shows its source and date next to the field.
Change any input and the page address changes with it, so you can bookmark a scenario or send it to a co-borrower, a loan officer or an agent. Nothing you type is stored on our server.
