Mortgage Calculator

Estimate your full monthly mortgage payment — principal, interest, property tax, insurance, and PMI if your down payment is under 20%.

Estimated total monthly payment
-

Property tax and insurance defaults are rough national-average placeholders — replace them with your actual local rates for an accurate estimate.

What's included in this mortgage payment estimate

This mortgage calculator estimates your full monthly payment using the standard "PITI" breakdown lenders use: Principal & Interest, property Taxes, home Insurance, and — if your down payment is under 20% of the home price — Private Mortgage Insurance (PMI). PMI is not charged once you've put down 20% or more, matching standard US lending practice.

Frequently asked questions

Why do I have a PMI charge?

PMI applies automatically whenever your down payment is under 20% of the home price — this protects the lender and is standard practice, not a fee this calculator invented.

Are the property tax and insurance numbers accurate for my area?

They start as rough placeholders. Replace them with your local property tax rate and actual insurance quote for a realistic number — these vary a lot by location.

Does the interest rate here need to be an APR?

Use the note rate (the rate on your loan estimate), not the APR, since APR bakes in fees this calculator doesn't model.
