Quick answer: Your debt-to-income ratio (DTI) is your total monthly debt payments divided by your gross monthly income. As rules of thumb in 2026: conventional loans commonly work up to the mid-40s (as high as 50% on strong automated approvals), FHA flexes higher with compensating factors, and VA has no hard cap — it leans on residual income instead. DTI is calculated on pre-tax income.
DTI is the number that actually decides how much house you can buy — more than your credit score, more than the rate. Here's exactly what counts as debt, what doesn't, the realistic limits by loan type, and the fastest ways to buy yourself more room.
Key takeaways
- DTI = monthly debt payments ÷ gross monthly income. Lenders care most about the "back-end" number, which includes your full proposed housing payment.
- What counts: minimum credit-card payments, car loans/leases, student loans, personal loans, support obligations, and the new PITI + HOA. What doesn't: utilities, groceries, phone, subscriptions.
- Room by program: conventional to ~50% with strong AUS files, FHA often higher with compensating factors, VA guided by residual income (41% is a guideline, not a wall).
- Fastest fix: eliminate a monthly payment, not a balance — paying off a $300/mo car loan frees more buying power than parking $10,000 in a card balance.
What is a debt-to-income ratio and how is it calculated?
DTI is your monthly debt load as a percentage of your gross (pre-tax) monthly income. Lenders look at two versions:
- Front-end DTI: just the proposed housing payment — principal, interest, taxes, insurance, and HOA (PITI) — divided by income.
- Back-end DTI: the housing payment plus every other monthly debt obligation. This is the number that drives approvals.
Gross income $8,000/mo. Proposed PITI $2,300. Car $450, student loans $250, card minimums $150.
Back-end DTI: ($2,300 + $450 + $250 + $150) ÷ $8,000 = 39.4%
Front-end DTI: $2,300 ÷ $8,000 = 28.8%
At 39.4%, this file has room in every program. Your actual qualifying math is confirmed in underwriting.
What counts as debt — and what doesn't
| Counts | Doesn't count |
|---|---|
| Proposed housing payment (PITI + HOA) | Utilities, phone, internet |
| Minimum credit-card payments | Groceries, gas, living expenses |
| Car loans and leases | Insurance not tied to the home |
| Student loans (program-specific calculation) | Subscriptions and memberships |
| Personal loans, other mortgages | Debts with fewer than ~10 payments left (often excludable) |
| Child support / alimony | 401(k) loans (repaid to yourself) |
Two details buyers constantly get wrong: it's the minimum card payment that counts (not your balance or what you actually pay), and it's gross income in the denominator — the pre-tax number, which works in your favor.
DTI limits by loan type in 2026
| Program | Typical comfort zone | Upper range with strong file |
|---|---|---|
| Conventional | Up to ~45% | ~50% with strong AUS approval |
| FHA | Up to ~43–45% | Higher with compensating factors (reserves, credit, residual income) |
| VA | ~41% guideline | No hard cap — residual income is the real test |
Valley West takeDTI limits aren't cliffs, they're negotiations with the automated underwriter — and the levers are reserves, credit score, and documented income. The file we see denied at 47% and approved at 47% is usually the same buyer, before and after we documented a bonus history or moved a car payment. If a pre-qual elsewhere told you "your DTI is too high," that's the beginning of the conversation, not the end. As a lender with a deep program bench, we can also re-run the same file under different overlay sets.
How can you lower your DTI fast?
- Kill payments, not balances: paying off a $450/mo car loan frees ~$450 of monthly debt; the same cash against a credit card only cuts the minimum payment slightly.
- Don't finance anything before closing: a new car or furniture plan mid-escrow can sink an approval overnight.
- Document all income: overtime, bonuses, a second job with a 2-year history, or a co-borrower's income all grow the denominator.
- Check the near-payoff rule: debts with roughly 10 or fewer payments remaining can often be excluded entirely.
- Buy the payment down: a temporary buydown doesn't change qualifying DTI (you qualify at the note rate), but permanent points lower the payment that goes into the ratio.

What is a debt-to-income ratio?
Your total monthly debt payments divided by your gross monthly income, as a percentage. It measures how much of your income is already spoken for before the mortgage is added.
What DTI do I need to buy a house in 2026?
Conventional commonly works to the mid-40s (up to ~50% with strong automated approval), FHA can flex higher with compensating factors, and VA uses residual income with 41% as a guideline rather than a cap. For what those compensating factors look like in practice, see our guide to FHA loans in Las Vegas.
Is DTI based on gross or net income?
Gross — pre-tax. The bigger denominator works in your favor.
Do utilities and subscriptions count in DTI?
No. Only credit obligations count: cards (minimum payments), auto loans, student loans, personal loans, support obligations, and the new housing payment.
What's the fastest way to lower DTI?
Eliminate an entire monthly payment — like paying off a car loan — and avoid financing anything new before closing. Documenting additional income helps just as much.
The bottom line
Your debt-to-income ratio is arithmetic, and arithmetic can be managed: know your back-end number, know your program's real range, and pull the two or three levers that move it before you shop. Most "denied for DTI" stories we hear were really "nobody structured the file" stories. Bring us the numbers and we'll show you the room you actually have.
