Front-end DTI
Housing payments (PITI for owners, rent for renters) divided by gross monthly income. Conventional underwriters generally want this under 28% for the strongest rates.
Actually. · DTI calculator
Debt-to-income is the single number that decides whether your loan gets approved and at what rate. This calculator gives you both the front-end (housing only) and back-end (all debts) DTI, plus the bands lenders use. Runs in your browser — nothing stored, nothing sent.
Back-end DTI (all debts)
39%
Acceptable · lenders may still qualify you, often at higher rates.
Lenders price loans in 5-point DTI steps. The U.S. median household sits around 35% back-end DTI; below 36% tends to get the cleanest pricing on mortgages and auto loans. Each 1-point drop widens what a lender will offer.
Bands sourced from Fannie Mae Selling Guide §B3-6 and FHA Handbook 4000.1 §II.A.5.d.
Two ways DTI gets better: pay off debt or earn more. The fastest single move is usually clearing one revolving balance — even closing a single $200/mo credit card minimum can drop a borderline DTI into the next band. The Actually. app shows which debt does the most for your DTI per dollar paid.
How lenders read DTI
Housing payments (PITI for owners, rent for renters) divided by gross monthly income. Conventional underwriters generally want this under 28% for the strongest rates.
All monthly debt payments — housing plus auto, student, cards, alimony, child support — divided by gross monthly income. Conventional mortgages typically cap this at 43% (sometimes higher with compensating factors).
Higher DTI rarely disqualifies you outright at the modern caps; it nudges your rate offer up. Even a 2-point reduction in DTI can change what a lender quotes you.
