Estimate your monthly mortgage payment — including principal, interest, property tax, and home insurance — and see exactly where your money goes.
This calculator uses the standard fixed-rate amortization formula to work out the principal and interest portion of your payment, then layers on property tax and home insurance for your real monthly cost.
Four factors drive the number above: the loan amount (home price minus down payment), the interest rate, the loan term, and your local property tax and insurance costs.
Interest rate has an outsized effect — even half a percentage point can shift your monthly payment by tens of dollars and your lifetime interest by thousands.
It's calculated from the loan amount, interest rate, and loan term using a standard amortization formula, then combined with property tax and insurance to show your full monthly housing cost.
20% is the traditional benchmark because it avoids private mortgage insurance (PMI), but many loan programs accept much less — sometimes as low as 3%.
Yes — enter your estimated annual figures and they're added automatically to your principal and interest payment above.
