The Math
How DTI Ratios Work
Front-End DTI (28% Rule)
Your total housing expense (principal, interest, taxes, insurance) should not exceed 28% of your gross monthly income. This is the primary guideline most lenders use for qualifying borrowers.
Back-End DTI (36% Rule)
Your total monthly debt payments (housing + car loans + student loans + credit cards + other debts) should not exceed 36% of your gross monthly income. Some loan programs allow up to 43% or even 50%.
