What is a Mortgage Calculator?
A Mortgage Calculator estimates your monthly home loan payment, including principal, interest, and optionally taxes, insurance, and other recurring costs.
Our free Mortgage Calculator helps you plan a home purchase with a realistic, comprehensive monthly payment estimate.
A mortgage payment estimate that only accounts for principal and interest can look significantly lower than what a homeowner will actually pay each month, since property taxes, homeowners insurance, private mortgage insurance, and HOA fees often add a substantial amount on top of the base loan payment, and many basic calculators leave these out unless specifically entered.
Our Mortgage Calculator lets you include taxes, insurance, and other recurring costs alongside principal and interest, aiming for a genuinely realistic monthly estimate rather than just the loan math in isolation. Private mortgage insurance specifically is usually required whenever a down payment is less than 20 percent of the home's price, and leaving it out of the calculation for a low-down-payment scenario will understate the real expected payment in a way that matters.
A 15-year mortgage and a 30-year mortgage on the identical loan amount produce very different monthly figures because the shorter term pays off the same total principal in fewer, larger installments, which in exchange typically results in significantly less total interest paid over the full life of the loan. It's worth treating any calculator's output as a solid starting estimate rather than a guaranteed number, since the actual rate a lender offers depends on your credit score, debt-to-income ratio, and current market conditions at the time you apply; a formal pre-approval from an actual lender gives a meaningfully more precise number than any calculator can.
