About This Calculator

Our home affordability calculator uses the widely-accepted 28/36 rule that mortgage lenders use to determine how much house you can afford.

How It Works

The front-end ratio (28%) means your total housing costs — mortgage principal, interest, property tax, and insurance — shouldn't exceed 28% of your gross monthly income.

The back-end ratio (36%) means your total debt payments (housing + car loans + student loans + credit cards) shouldn't exceed 36% of your gross monthly income.

Our calculator finds the maximum home price that satisfies both constraints simultaneously, accounting for your down payment, interest rate, property taxes, insurance, and PMI when applicable.

Accuracy

This calculator provides estimates based on standard lending guidelines. Actual approval depends on your credit score, employment history, assets, and the specific lender's criteria. Always get pre-approved for the most accurate number.
