Rough planning ceiling from income, debts, credit tier and down payment — income-multiple and DTI caps compared side by side. Not an approval.
Rough planning ceiling from income, debts, credit tier and down payment — income-multiple and DTI caps compared side by side. Not an approval.
Enter values above and click Calculate — results will appear here with the formula explained.
Eligibility triangulates three caps: income multiple (roughly 4.5× gross annual income as a ceiling), debt-to-income (housing plus debts under 36% ideal, 43–45% maximum for qualified mortgages), and credit-tier adjustment (750+ full amount, low-700s ~90%, mid-600s ~80%). The binding constraint — whichever yields the smallest loan — is your realistic max, which is why this calculator shows all three instead of one headline.
DTI is where most applications live or die: front-end (housing only) ideally ≤28%, back-end (all debts) ≤36% for best terms and ≤43–45% for qualified-mortgage approval. A $5,000 monthly income with $800 debts supports about $1,000 in housing at 36% back-end — every $100 of car or student-loan minimum erases roughly $15,000–$20,000 of borrowing power at current rates.
Credit score moves both access and price: 760+ unlocks best rates and full multiples, 700–759 pays measurably more, 660–699 faces higher rates plus PMI pain on low down payments, and below 660 conventional options thin toward FHA (580+ with 3.5% down) or manual underwriting. A 40-point score gain can save a quarter point of rate — tens of thousands over 30 years.
Down payment interacts with everything: 20% avoids PMI and unlocks best pricing, 10–15% adds moderate PMI, 3–5% (conventional HomeReady, FHA) maximizes access at higher monthly cost. Gift funds, grants and employer assistance count differently per program — document the source, because undocumented deposits trigger underwriting holds.
Employment and reserves complete the picture lenders actually use: 2-year history (W-2 stability beats job-hopping), 2–6 months of reserves post-closing, and no new debt between pre-approval and closing — the classic denial trigger is a financed car the week before settlement. Self-employed borrowers face income averaging with add-backs; prepare two tax years plus YTD profit-and-loss.
This is a planning estimate — real underwriting adds appraisals, title, flood certs, condo reviews, overlays above agency minimums, and automated findings (DU/LP) that no calculator replicates. Use the max here as a shopping ceiling, then get pre-approved (verified) rather than pre-qualified (stated) before writing offers.
Rough planning ceiling from income, debts, credit tier and down payment — income-multiple and DTI caps compared side by side. Not an approval. Formula: Rough planning ceiling = min(4.5 × gross annual income, affordable-mo × ~165).

With $5,000 monthly income, $800 debts, 720 score and 20% down: income cap = 4.5 × $60,000 = $270,000; affordable monthly = 36% × $5,000 − $800 = $1,000, so DTI cap ≈ $1,000 × 165 = $165,000 — DTI binds, rough max ~$165,000 with ~$33,000 cash needed at 20% down. Clearing the $800 debts lifts affordable monthly to $1,800 and the DTI cap to ~$297,000, past the income cap — the highest-leverage move before applying.
