Mortgage Calculators
Run the numbers on home loans — payments, refinancing, points, ARMs and the rent-versus-buy question.
A mortgage is built from a handful of moving parts — price, down payment, rate, term and the taxes and insurance folded into the payment. These calculators let you change one at a time and watch the monthly cost and lifetime interest respond, so a "should I?" question becomes a number you can compare.
Start by sizing the payment and what you can afford, then use the focused tools — refinance break-even, 15- vs 30-year, points, PMI, extra payments — to pressure-test the specific decision in front of you.

Some do. The basic mortgage calculator shows principal and interest only; the calculator with taxes and insurance (and the PMI version) adds property tax, homeowners insurance and mortgage insurance for the full monthly payment. Pick the one that matches what you want to see.
How accurate are these mortgage calculators?
They use the same standard amortization math lenders use, so the payment and total-interest figures are reliable planning estimates. Your exact rate, taxes and insurance come from a lender quote, so treat the results as a close estimate, not a final number.
Which mortgage calculator should I start with?
Start with the mortgage calculator for your monthly payment, then the mortgage qualifier to see how much house you can afford. From there, use the focused tools — refinance, points or extra payments — for the specific decision in front of you.
