Mortgage Affordability Calculator 2026 (USA) | How Much House Can I Afford?

A Mortgage Affordability Calculator estimates how much home price you may be able to afford based on your income, debts, and basic financial details. It provides an indicative borrowing and price range rather than a guaranteed approval amount. The results are meant for planning and general understanding.

The calculator uses your income, monthly expenses, existing debts, deposit amount, interest rate, and loan term to estimate an affordable mortgage. It applies commonly used affordability principles in the United States. Outputs are indicative and may vary from lender assessments.

You typically enter household income, monthly debts, down payment, interest rate, and loan term. Providing realistic figures improves the usefulness of the estimates. All amounts should be entered in U.S. Dollars.

FHA loans allow up to 50% under compensating factors. VA loans up to 60%. The calculator applies 43% as standard; verify with your lender.

PITI (Principal, Interest, Taxes, Insurance) should all be included in your affordability calculation. Front-end DTI (housing costs ÷ income) is typically capped at 28%. On $5,000 income, max PITI is ~$1,400/month. Add HOA, PMI, title, and property taxes to your real monthly cost. This calculator estimates these; verify with your lender.
