How affordability is estimated
This tool applies two common debt-to-income (DTI) guidelines: your housing payment should stay at or below 28% of gross monthly income (front-end ratio), and your total debt — including housing — should stay at or below 36% (back-end ratio).
Your maximum loan is then reverse-calculated from that affordable monthly payment using the standard amortization formula, and the maximum home price is the loan amount divided by one minus your down-payment percentage.
