How Home Affordability Is Calculated
Lenders use two key debt-to-income (DTI) ratios to determine how much mortgage you qualify for:
- Front-end DTI (28%): Your monthly housing costs (principal, interest, taxes, insurance) should not exceed 28% of your gross monthly income.
- Back-end DTI (36%): All monthly debt payments combined (housing + car + student loans + credit cards) should not exceed 36% of gross monthly income.
- PMI: If your down payment is less than 20%, most lenders require Private Mortgage Insurance — typically 0.5–1.5% of the loan per year.
- FHA loans allow higher DTI ratios (31/43) with as little as 3.5% down, but require mortgage insurance premiums.
Results are estimates for planning purposes. Your actual loan offer will depend on your credit score, employment history, and the lender’s criteria. Always get pre-approved before making an offer.
