How an FHA Loan Counts Monthly Debts Versus a Conventional Loan

The Quick Read: Both loan types add up your monthly obligations and compare them to your gross monthly income, but the rulebooks differ on the details. FHA publishes tiered ratio limits that stretch with documented strengths. It also counts every student loan, whatever its payment status. Conventional guidelines lean on automated findings, more flexible treatment of some debts, and a ten-month rule for short installment loans. Which one “counts less” depends on your specific debts.

The Honest Answer First

FHA tends to fit borrowers with a mid-range credit profile, a thinner down payment, or a debt load that looks heavy on paper but is well documented. Conventional tends to fit borrowers with stronger credit, more equity or cash to put in, and debts that the conventional rules treat gently, such as a documented zero-payment income-driven student loan.

Neither is looser across the board. The ratio ceiling is only one piece. How each debt gets counted, and what else the file shows, decides the outcome.

Side-by-Side

Every figure is subject to lender guidelines and full file review. Nothing here is a commitment to lend. County loan limits apply to FHA loans and change every year.

How Does an FHA Loan Count Monthly Debts?

An FHA lender calculates two ratios: housing payment to income, and total fixed payments to income. Both use your gross, pre-tax monthly income. The CFPB defines DTI as all monthly debt payments divided by gross monthly income, and notes that limits differ by product and lender.

Across the wholesale FHA programs we place files with, the base pair is 31/43. That means housing costs up to 31% of income and total debts up to 43%. Documented compensating factors can stretch the total higher, reaching 40/50 at the top tier. HUD’s published ratio tiers for manual underwriting show how this works:

• No compensating factors: 31/43.
• One compensating factor: a higher tier, with verified cash reserves, a minimal increase in housing payment, or residual income as the qualifying strengths.
• No discretionary debt: a separate tier with equal housing and total ratios.
• Two compensating factors: the 40/50 top tier.

A file with a score under 580, or no score, stays capped at 31/43, according to HUD Mortgagee Letter 2026-11. That letter also updates how the minimum decision credit score is determined, allowing alternative score models. It does not change the ratio tiers.

Most FHA files start with an automated finding. The finding governs most of them. A “Refer” result sends the file to manual underwriting, where those tiers apply directly.

Your housing payment includes the FHA mortgage insurance. The upfront premium is 1.75% of the base loan, usually financed. The annual premium runs between 0.15% and 0.75% of the balance, depending on term, loan amount and LTV. On a thirty-year loan above 90% LTV, the annual premium lasts the loan’s term. At or below 90%, it ends after eleven years. That premium sits inside your housing payment, so it pushes the ratio up.

How Does a Conventional Loan Count Them?

Conventional loans typically follow Fannie Mae’s Selling Guide, which also builds DTI from total monthly obligations and income. The guide allows lenders to be more conservative than its minimums, as long as they apply the approach consistently. So two conventional lenders can read the same file differently.

The exact conventional maximums depend on the automated finding and the manual-underwriting rules in that guide. We won’t quote a single number here, because it shifts with the file.

Obligations that count on a conventional file include:

• Revolving payments, such as credit card minimums.
• Lease payments, regardless of the expiration date.
• Alimony or child support with more than ten months remaining.
• Net rental loss, where it applies.
• Installment debt, including auto, personal and student loans, and timeshares.

Installment debt counts when more than ten monthly payments remain. A shorter debt can still count if it significantly affects your ability to meet your obligations. So “under ten months never counts” is a misconception.

Where the Two Rulebooks Part Ways on Specific Debts

Student loans. This is the biggest practical difference. HUD requires the lender to include all student loans in your liabilities, regardless of payment type or status. A deferred loan still adds an assumed monthly obligation. A documented actual payment is one path. When the credit report shows no payment, the lender uses a percentage of the balance.

Conventional rules offer a different menu. When the file documents a zero payment on an income-driven plan, the lender may qualify the loan using that zero payment. Which treatment helps you depends on your loan documents.

Short-term installment debts. Conventional has the explicit ten-month rule. FHA also looks at debts with short remaining terms, but the current HUD handbook text decides, so confirm it with your loan officer before counting on a payoff to help.

Collections. FHA does not automatically require you to pay a collection. A cumulative balance above a set threshold can trigger a payoff, a payment arrangement, or a calculated monthly payment. The handbook sets the threshold and method.

Debts paid by someone else. Conventional guidelines can exclude a debt that another party pays, with documented payment history. FHA has its own documentation rules here as well. Ask before assuming a co-signed or family-paid debt drops out.

Rental housing liability. On conventional loans, a non-occupant co-borrower, second home or investment property can bring a rental housing payment into the ratio. An FHA purchase is for a principal residence, so occupancy decides the leverage.

Federal backdrop. The 43% figure is an FHA and industry benchmark, not a federal legal cap. The CFPB’s General QM rule replaced the old 43% limit with a limit based on loan pricing.

One Borrower, Two Readings

Picture a buyer with a car loan that has twelve payments left, a credit card with a modest minimum, and a student loan in deferment. On a conventional file, the car loan counts because more than ten payments remain. The student loan might count at a documented amount or a balance percentage. On an FHA file, the student loan counts no matter its status, and the lender may use a balance percentage if the report shows no payment.

Same debts, different counting. The same buyer might look better on one side and worse on the other once mortgage insurance, down payment and credit score enter the picture. That is why a side-by-side file review beats a rule of thumb.

When an FHA Loan Is the Better Fit

An FHA loan tends to fit when:

• Your credit score sits in the mid-range. The wholesale programs we place with start at a 580 decision score, with 3.5% minimum investment.
• Your debt load is heavy but well documented. Reserves, a small housing payment increase, or residual income can lift the ratio ceiling.
• Your down payment is small. Financing reaches 96.5%, and seller or interested-party contributions can go to 6% of the price.
• A non-occupant co-borrower strengthens the file. That is allowed.
• You have a past credit event. HUD’s waiting periods are two years from a Chapter 7 discharge and three years from a foreclosure. Those are HUD rules, not a promise from any lender.

The flip side: FHA mortgage insurance is a permanent-feeling cost on high-leverage loans. If you borrow above 90% LTV on a thirty-year term, the annual premium lasts the full term. A borrower who expects to hold the loan long term should weigh that. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.

When a Conventional Loan Is the Better Fit

Conventional tends to fit when:

• Your credit is strong. Better scores usually mean more flexibility in how the file is read.
• Your student loan is on an income-driven plan with a documented zero payment. Conventional guidelines can count that zero.
• A debt is within the ten-month window. Paying it down toward that mark can change how it counts.
• You want a second home or other occupancy. FHA purchases are for a principal residence only.
• You can put more down. Lower leverage can reduce or remove private mortgage insurance, depending on the program.

The flip side: if your ratios are tight and you have no documented strengths, a conventional lender may have less room to stretch than FHA’s tiers allow, and some lenders add overlays stricter than the agency minimum. Both loan types allow overlays, so a file one lender declines may look different to another.

Practical Moves Before You Apply

Lowering the counted number usually means lowering the monthly payment, not just the balance. A few cautions:

1. Pull your credit report first. Errors and old accounts can add payments you don’t owe.

2. Talk to a loan officer before paying debts off. Draining cash can hurt reserves, which are themselves a compensating factor on FHA files.

3. Gather student loan paperwork. The actual payment, plan type and servicer statement can change the counted amount.

4. Expect a re-check. New debts found before closing can send the file back through underwriting, so avoid new credit.

5. Remember the appraisal. It affects value and property eligibility. It does not change how debts are counted, though FHA appraisals also check safety and condition.

Key Terms Defined

Debt-to-income ratio (DTI): Your monthly debt payments divided by your gross monthly income.

Front-end ratio: The share of gross income that goes to the housing payment, including mortgage insurance.

Back-end ratio: The share of gross income that goes to housing plus all other monthly debts.

Compensating factor: A documented strength, such as cash reserves, that lets a file exceed the base ratio.

Installment debt: A loan with fixed periodic payments, such as an auto or personal loan.

Overlay: A lender rule stricter than the agency’s minimum.

Balanced Verdict

Neither loan counts debts “more kindly” in every case. FHA offers published tiers and strong stretch potential for documented files, but it counts every student loan. Conventional offers more flexibility on some debts and occupancy types, but its limits move with the automated finding and each lender’s overlays. Compare both on your actual numbers before choosing.
