FHA's standard debt-to-income guideline is 31% for housing costs and 43% for total monthly debts, measured against gross monthly income. Automated underwriting may approve higher ratios when the file shows strengths such as reserves, strong credit, or minimal payment increase, and manually underwritten files can exceed the benchmarks with documented compensating factors — generally, and subject to lender overlays.
The two ratios
Front-end (housing) ratio
Your new total house payment — principal, interest, property taxes, homeowners insurance, MIP, and any HOA dues — divided by gross monthly income.
Back-end (total) ratio
The house payment plus every recurring debt on your credit report or in court orders — cards, auto, student loans, support — divided by gross monthly income.
Gross income means before taxes and deductions. Everyday living expenses like groceries, utilities, and phone bills aren't part of DTI, which is why it's worth building your own budget alongside the lender's math.
The 31/43 guideline and when it bends
The 31% / 43% pair is FHA's standard benchmark for manually underwritten loans. Most FHA files, though, are first run through an automated underwriting system (AUS), specifically FHA's TOTAL Scorecard. It weighs the whole file — credit, reserves, down payment, ratios — and can return an approval with ratios above 43% when the rest of the file is strong.
If the AUS refers the loan to a human underwriter, manual underwriting applies, and ratio limits then depend on your credit and the compensating factors you can document. Lenders can also add overlays that cap DTI below what FHA allows.

Talk with MatthewCompensating factors
- Cash reserves left over after closing, measured in months of house payments.
- Minimal increase in housing payment compared with your current rent or mortgage.
- Residual income — meaningful money left each month after debts and living costs.
- Significant additional income not used to qualify, such as documented part-time or overtime income without enough history.
- A strong credit history with no late payments and conservative use of credit.
- An energy-efficient home that lowers expected utility costs.
How common debts are counted
| Debt | How it generally counts |
|---|---|
| Credit cards | The minimum payment on your credit report, even if you pay in full |
| Car loans and leases | The monthly payment; installment debts ending within about 10 months may be excluded if the payment isn't large (leases always count) |
| Student loans | The actual documented payment; if the reported payment is zero (deferred, or an income-driven plan reporting nothing due), FHA uses a calculated figure based on the balance |
| Child support and alimony | The court-ordered amount; alimony may be deducted from income instead in some cases |
| Co-signed loans | Counted unless you document that the other person has made the payments |
| Collections | Larger non-medical collection balances may add a calculated amount unless paid or on a plan |
The student loan rule surprises people most. A deferment that shows a zero payment on your report doesn't mean zero in the FHA calculation. Matthew can show you exactly how your loans will be counted before you house-hunt.
Ways to improve your DTI
- Pay down revolving balances to lower minimum payments — even small reductions add up.
- Pay off small installment debts that are near the end of their term.
- Get a documented income-driven student loan payment if your report shows zero or an outdated amount.
- Add a co-borrower, including an eligible non-occupant relative, when their income outweighs their debts.
- Adjust the target price, look for lower property taxes or HOA dues, or increase the down payment.
- Hold off on new debt — no new car or furniture financing until after closing.
A simple example
Say a borrower earns a steady salary and has a car payment, two credit cards, and student loans in an income-driven plan. The lender adds the projected house payment (including taxes, insurance, and MIP) to get the front-end ratio. Then it adds the car payment, the card minimums, and the documented student loan payment to get the back-end ratio.
If the back-end ratio lands a bit above 43%, the file isn't dead. The AUS may still approve it because the borrower has solid credit and a few months of reserves. If it's referred, the underwriter will look for documented compensating factors. And if it's well above what FHA allows, the fix may be as simple as paying off a small card balance or choosing a slightly lower price range.
Approval isn't the same as comfortable
DTI tells a lender whether a loan fits guidelines. It doesn't account for childcare, commuting, saving for retirement, or the repairs that come with owning a home. Before you settle on a price range, build a budget you can actually live with. Matthew will give you the lender's view and an honest one. HUD updates its handbook regularly and lenders can add their own overlays, so Matthew will confirm the current guidelines for your file.
Frequently asked questions
What is the maximum DTI for an FHA loan?
The standard benchmark is 31% housing and 43% total. Automated underwriting can approve higher ratios for strong files, and manual underwriting allows higher ratios with compensating factors. Lenders may cap lower.
Does rent count in my DTI?
Your current rent doesn't, because the new house payment replaces it. If you'll keep paying rent elsewhere, that may count.
Do utilities and phone bills count?
No. DTI covers housing costs and debts that appear on your credit report or in court orders, not ordinary living expenses.
Can rental income help with DTI on a duplex?
Often, yes. Projected rent from the other units of a 2–4 unit property may be partly counted, subject to FHA rules and appraisal support.
Should I pay off a car loan before applying?
Sometimes. It depends on the balance, the payment, and how much cash you'd have left. Ask Matthew to compare scenarios before spending savings.
