How It Works
The home affordability calculator uses two standard lending guidelines: the 28% front-end rule (housing costs should not exceed 28% of gross monthly income) and the 43% back-end DTI rule (total debt payments should not exceed 43%).
The calculator takes the lower of these two limits as your maximum monthly housing payment, then reverse-engineers the maximum loan amount from your interest rate and term.
Maximum home price = Maximum loan + Down payment. This is a conservative estimate — actual lender decisions also depend on credit score, employment history, and other factors.
