Actual Mortgage Cost Calculator

Know what you'll ACTUALLY pay before buying a home — principal, interest, taxes, insurance, PMI, HOA, utilities, and maintenance, right on the listing page.

How it works

No account, no setup. Click it on a listing you're already looking at.

1

Browse a listing

Shop like normal on Zillow, Realtor.com, Redfin, Homes.com, or Trulia.

2

Click the extension

It reads the price, address, beds/baths, HOA, tax, and insurance off the page — you fill in your loan terms.

3

See the real cost

Full monthly breakdown, cash needed at closing, affordability check — instantly.

What it shows you

Not just the listing price. What it actually costs you every month to own it.

Full monthly cost breakdown

Principal, interest, property tax, homeowners insurance, PMI, HOA, utilities, and maintenance — all in one number, not scattered across a closing disclosure.

Move-in cash calculator

Down payment, closing costs, inspection, appraisal, earnest money, moving costs, and immediate repairs — totaled before you offer.

Affordability check

Enter your income and it scores the home honestly against standard debt-to-income guidelines, so you know before you offer whether it's a stretch.

Smart insights

Flags PMI you could avoid, high tax/insurance areas, and costs that run over what a lender would typically approve.

Extra payment & ownership timeline

See how an extra $50–$500/month changes your interest paid and payoff date, plus a year-by-year equity timeline.

Rent vs. buy comparison

Compare against a comparable rental nearby — monthly, annual, and five-year difference, cash required included.

History & side-by-side compare

Every home you've looked up is saved locally, so you can pull up two and compare them directly.

Downloadable mortgage cost report

A clean summary you can save or share, so the numbers don't just live in a browser tab.
