Home Affordability Calculator

Estimate a home-price range from your income, debts, and down payment using standard lending guidelines.

Estimated price ceiling$377,583

Understanding this calculator

Lenders start from two guideline ratios: housing costs near 28% of gross monthly income (the front-end ratio) and all debt payments near 36% (the back-end ratio). Whichever is tighter sets your budget, and this calculator solves the largest price whose full payment — principal, interest, property taxes, and insurance — fits inside it.

Treat the result as a ceiling, not a target. The guidelines ignore your savings rate, childcare, healthcare, and how secure your income feels — and a house at the very top of the range leaves no room for any of them. Many comfortable homeowners deliberately buy below what lenders would approve.

Assumptions and methodology

  • Housing budget = the lesser of (front-end % × monthly income) and (back-end % × monthly income − existing monthly debts).
  • The price is solved so PITI (principal, interest, taxes at your rate, insurance, HOA) equals that budget, given your down payment, rate, and term.
  • 28/36 are adjustable general planning guidelines, not underwriting decisions; actual approval depends on credit, reserves, loan program, and lender overlays.
  • PMI, points, and closing costs are not included in the affordability solve.

Common questions

Why is my result lower than a lender's pre-approval?

Pre-approvals often stretch to the program maximum (some allow back-end ratios well above 36%). This tool defaults to the conservative guideline range because payments you can make and payments you can live with are different things.

Does a bigger down payment help?

Twice over: it shrinks the loan the payment must cover and can eliminate PMI once you reach 20%. Every $10,000 down adds roughly $10,000 of price at the same payment.
