FHA Debt-to-Income (DTI) Limits, Explained

When you apply for an FHA loan, your lender looks closely at one number: your debt-to-income ratio, or DTI. It shows how much of your monthly income already goes to debt. The standard FHA limits are 31% and 43%, but many buyers are approved above that. This guide explains the limits, how they're calculated, and what you can do if your numbers are close.

What DTI is

Your debt-to-income ratio compares your monthly debt payments to your gross monthly income, which is your income before taxes. Lenders use it to judge whether you can afford a new mortgage payment on top of what you already owe.

FHA looks at two versions of the ratio:

• Front-end ratio (housing ratio): your new monthly housing payment divided by your gross monthly income
• Back-end ratio (total DTI): your new housing payment plus all your other monthly debts, divided by your gross monthly income

When you see FHA limits written as 31/43, the first number is the front-end limit and the second is the back-end limit.

The FHA DTI limits

FHA's rules are set by the U.S. Department of Housing and Urban Development in HUD Handbook 4000.1. The baseline is:

• 31% for your front-end (housing) ratio
• 43% for your back-end (total) ratio

Those numbers are a starting point, not a hard ceiling. How high your lender can go depends on how your loan is underwritten.

When you can go above 43%

Most FHA loans run through FHA's automated underwriting system, called TOTAL Scorecard. It weighs your whole application, including credit, savings, and income, and returns either “Accept” or “Refer.”

Automated approvals

If your file gets an “Accept,” the system can approve a DTI above 43%. FHA doesn't publish a fixed maximum for automated approvals, but loan officers commonly see approvals with a back-end ratio up to about 57% for borrowers with strong files. Your credit score, savings, and job history all affect how high the system will go.

If your credit score is below 620 and your DTI is above 43%, the system may send your file to manual underwriting instead.

Manual underwriting

When a file gets a “Refer,” an underwriter reviews it by hand. Manual underwriting has published DTI limits, and they depend on your credit score and your compensating factors:

‍

In the top two rows, an energy-efficient home can qualify for slightly higher “stretch” ratios of 33% / 45%. To count as energy efficient, a home needs documentation, such as an ENERGY STAR label for a manufactured home or a Home Energy Score of 6 or higher for an existing home. Your lender confirms whether a home qualifies.

What counts as a compensating factor

Compensating factors are strengths in your application that offset a higher DTI. FHA recognizes a short list:

• Cash reserves: verified savings left over after closing, generally at least three months of mortgage payments. Gifts and borrowed money don’t count.
• Minimal increase in housing payment: your new payment is no more than $100 or 5% higher than you current rent or mortgage payment (whichever is less) and you have a solid 12-month payment history.
• Significant additional income: steady income your lender didn't count in your qualifying income, such as overtime or a part-time job. It needs at least a one-year history and only counts when paired with a second compensating factor.
• Residual income: enough money left each month after paying all your bills and housing costs

One compensating factor (cash reserves, a minimal payment increase, or residual income) allows up to 37% / 47%. Two factors allow up to 40% / 50%.

“No discretionary debt” is a separate category. It applies when your housing payment is the only account you carry a balance on. You can still have credit cards, as long as you’ve paid them in full every month for the past six months.

Your lender's own limits

Some lenders set stricter limits than FHA requires. These are called overlays. If one lender can't approve your DTI, another lender might, so it can be worth asking more than one.

What counts as debt and income

Your housing payment (front-end)

Your housing payment is the full monthly amount for your new home:

• Principal and interest
• Property taxes
• Homeowners insurance
• FHA mortgage insurance premium (MIP)
• HOA dues, if any

Your other debts (back-end)

Your back-end ratio adds the monthly payments on debts that show up on your credit report or in your records:

• Car loans and leases
• Student loans
• Minimum payments on credit cards
• Personal loans
• Child support and alimony
• Payments on any other property you own

Everyday bills like utilities, phone plans, groceries, and car insurance are not part of your DTI. Installment loans that will be paid off within 10 months can be left out if their combined payments are 5% or less of your gross monthly income. You can't pay a loan down just to get under 10 months, and car lease payments always count.

Student loans

FHA counts student loans even if they’re deferred or in forbearance. Under Mortgagee Letter 2021-13, your lender uses the payment on your credit report or your documented payment. If the payment shows as $0, your lender counts 0.5% of the balance instead. On a $40,000 balance, that's $200 a month added to your DTI. Loans documented as forgiven, canceled, or discharged can be left out

Your income

Lenders use your gross monthly income, before taxes. It needs to be stable and likely to continue, such as salary, hourly wages, or self-employment income with a two-year history. One-time payments usually don't count as qualifying income.

How to calculate your DTI

Here's an example for a buyer earning $72,000 a year, or $6,000 a month before taxes.

• Front-end ratio: $1,800 ÷ $6,000 = 30%
• Back-end ratio: $2,550 ÷ $6,000 = 42.5%

This buyer is within the standard 31/43 limits. If their student loan payment showed as $0 on a $40,000 balance, the lender would count $200 instead of $250, and the back-end ratio would drop to 41.7%.

How to lower your DTI

If your ratio is close to the limit, small changes can make a difference:

• Pay down revolving debt. Lowering a credit card balance lowers its minimum payment.
• Pay off a small loan. Clearing a loan with only a few payments left removes it from your back-end ratio.
• Avoid new debt before closing. A new car loan or credit card can push your ratio over the limit late in the process.
• Look at a lower price range. A smaller loan means a smaller housing payment.
• Add a co-borrower. A spouse or family member's income can be counted alongside yours, along with their debts.
• Document all your income. Overtime, bonuses, or part-time work with a steady history may count if you have the paperwork.
• Build your savings. Cash reserves won't change the ratio itself, but they're one of FHA's compensating factors.

Your loan officer can run your numbers and tell you which of these would help most.

A HUD-approved housing counselor can also review your budget and debts for free or at low cost. You can find one through the CFPB's housing counselor search.

Where Hoper fits

Qualifying for a payment and comfortably affording it aren't the same thing. The first few years after closing are when an unexpected expense is most likely to cause trouble, and that's what Hoper is built for.

The Hoper program is run by Attainable Housing Advocates, a social innovation company that develops programs to help homeowners succeed over the long term. Hoper stands for Home Ownership Promotion, Education, and Research. Hoper is not a lender and doesn't change your rate or loan type. Your lender still reviews your DTI and decides whether you qualify.

Here's how Hoper relates to the numbers in this guide:

• No new monthly debt. Eligible participants earn up to 5% of the purchase price, capped at $16,000, as 1099 income. It isn't a loan and there's no second lien, so it doesn't add a payment to your back-end ratio. Some down payment assistance is a second loan with its own monthly payment. See how Hoper compares to down payment assistance.
• Cash reserves. The earnings can go toward closing costs or cash reserves, as your lender's guidelines allow. Ask your loan officer how they treat those funds in your file. Whether those funds count toward FHA's cash reserves compensating factor is up to your lender, so ask your loan officer how they treat them in your file.
• The solar system is part of your mortgage. Every participant includes a fully owned solar system in their mortgage, so your loan officer includes it when calculating your housing payment. The system is designed to help control your energy costs over time. Those costs aren't part of your DTI, but they're part of your real monthly budget.
• Education before closing. The pre-closing course covers what lenders look at and how to strengthen your profile, including your debts.

The earnings are a one-time payment, so they generally aren't counted as qualifying monthly income. They're also taxable, and a tax professional can explain how they affect you.

Common questions about FHA DTI limits

What is the maximum DTI for an FHA loan? The standard FHA limits are 31% for your housing payment and 43% for total debt. Manual underwriting allows up to 40% / 50% with compensating factors. Automated approvals can go higher. FHA doesn't publish a maximum, but lenders report approvals up to about 57% total DTI for strong files. 

What's the difference between front-end and back-end DTI? Front-end DTI is your housing payment divided by your gross monthly income. Back-end DTI adds all your other monthly debts, like car loans, student loans, and credit card minimums.

Does FHA count student loans in deferment? Yes. FHA counts every student loan. If your credit report shows a $0 payment, your lender uses 0.5% of the balance as the monthly payment.

What are FHA compensating factors? They're strengths that let a manual underwriter approve a higher DTI: verified cash reserves, a small increase over your current housing payment, steady income that wasn't counted, and strong residual income. Significant additional income only counts when paired with a second factor. 

Does credit score affect FHA DTI limits? Yes. With manual underwriting, a score below 580 limits you to 31% / 43%. With a score below 620 and a DTI above 43%, your file may need manual underwriting.

Does Hoper affect my DTI? Hoper earnings aren't a loan and don't add a monthly payment. The owned solar system is included in your mortgage, so your loan officer counts it in your housing payment. Your lender reviews your DTI as part of the normal mortgage process. See the Hoper FAQ for more.
