Front-End DTI = Housing Payment ÷ Gross Monthly Income
Back-End DTI = All Monthly Debts ÷ Gross Monthly Income

Lenders use two DTI thresholds: Front-end ≤ 28% (housing costs only) and back-end ≤ 36% for conventional loans (up to 43% for FHA). Your back-end DTI is the more critical number — it includes every recurring debt obligation including minimums on credit cards.
