Mortgage Calculator

Estimate your monthly mortgage payment, total interest, and loan cost — built for U.S. home prices, rates, and terms.

Monthly payment (P&I) Enter your numbers above
This calculator gives an estimate only. Actual payments depend on your lender, credit, and local taxes/insurance — not financial advice.

How the mortgage calculator works

This tool uses the standard fixed-rate amortization formula that U.S. lenders use to calculate your monthly principal and interest (P&I) payment. Enter your home price, down payment, interest rate, and loan term, and the calculator instantly shows your estimated monthly payment, total interest paid over the life of the loan, and (optionally) an all-in monthly estimate including property tax and homeowners insurance.

What affects your mortgage payment?

  • Loan amount — home price minus your down payment.
  • Interest rate — even a 0.5% difference changes your payment significantly over 30 years.
  • Loan term — a 15-year loan has higher payments but far less total interest than a 30-year loan.
  • Property tax & insurance — often collected monthly through an escrow account.

Frequently asked questions

Does this include PMI?
No. If your down payment is under 20%, most U.S. lenders require private mortgage insurance (PMI), which isn't included in this estimate and should be added separately.
Is this the same as my lender's quote?
It's a close estimate using the standard amortization formula. Your lender's official Loan Estimate may include fees, PMI, and rate details that shift the final number slightly.
What's a good mortgage rate in 2026?
Rates vary by credit score, loan type, and lender. Compare Loan Estimates from at least three lenders to find your best rate.
