The FHA debt-to-income ratio, or DTI, is one metric used to determine if a borrower qualifies for a home loan backed by the Federal Housing Administration (FHA). Specifically, DTI measures what proportion of your gross monthly income is used for debt repayment each month. If you’re interested in applying for an FHA loan, a type of home loan that is especially popular with first-time homebuyers and those who have limited savings for a down payment, it’s important to take the time to understand how the DTI ratio works and what numbers you’ll need to qualify.

Key Points
• The FHA debt-to-income (DTI) ratio is a key metric for FHA loan qualification, measuring the proportion of gross monthly income allocated to debt repayment.
• FHA loans use two DTI ratios: a front-end limit of 31% for housing costs and a back-end limit of 43% for housing plus all other monthly debts.
• Borrowers can potentially qualify with a DTI up to 55% if they have strong compensating factors.
• To calculate your back-end DTI, you divide your total monthly debt payments by your gross monthly income and multiply by 100.
• Borrowers can improve their DTI ratio and increase their chances of approval by paying down existing debt, finding a less expensive home, or improving their credit score.
Front-End vs. Back-End DTI
The maximum DTI ratio for FHA loan eligibility is 31% on the front-end, and 43% on the back-end. A thorough understanding of what those numbers mean is essential if you plan to apply for an FHA home loan. The front-end FHA DTI measures the percentage of your gross income that’s allocated for housing costs each month. That includes your mortgage payment, homeowners insurance, mortgage insurance, and property taxes. On the back-end, the FHA debt-to-income ratio includes your housing costs and any other debts you pay, such as credit cards, student loans, and home loans.
Each DTI has a different upper limit, as noted, and the FHA distinguishes between the two to determine:
• Your ability to handle your estimated mortgage payment, based on your current income, loan size, and expected interest rate.
• Your capacity to manage all of your debt obligations, including the mortgage.
While lenders consider your debt-to-income ratio for FHA loan applications, it’s just one factor that influences your ability to qualify. FHA lenders also review your credit scores, employment history, assets, and the property that you plan to buy to determine whether to approve you for a loan.
FHA DTI Ratio Limits for 2025
As we’ve seen, the current FHA mortgage debt-to-income ratio limits are 31% on the front end and 43% on the back end. However, it’s possible to qualify for an FHA loan with a DTI ratio up to 57% if you’re approved through an automated underwriting system or have strong compensating factors.
FHA Compensating Factors That Allow Higher DTI Ratios
Compensating factors help to offset a higher debt-to-income ratio and minimize how risky a lender perceives a borrower to be. Some of the factors that could allow you to qualify if you’re above the max DTI for FHA loans include:
• Substantial cash reserves that you could fall back on to make mortgage payments if necessary
• Steady employment, and/or multiple streams of income that you can rely on
• Income that trends up year over year, based on what you have reported on your tax returns
• Higher credit scores (for example, 670 or better)
• Minimal debt, outside of the anticipated mortgage
• A larger down payment
Borrowers with a credit score of 580 or better can qualify for an FHA loan with a minimum down payment of 3.5%. Increasing your down payment to 10% or more could help you get approved if your DTI is above the 43% mark. Note that if your credit score is between 500 and 579, you must put down a minimum of 10%; that is a standard FHA loan requirement.

FHA vs. Conventional Loan DTI Requirements
While FHA loans use the 31/43 rule for DTI requirements, with a 50% maximum allowed for compensating factors, conventional home loan lenders may use different figures. A conventional loan is one that’s guaranteed by a private lender or a government-sponsored enterprise, like Fannie Mae or Freddie Mac. In comparison to FHA loans, Fannie Mae and Freddie Mac use a 36% front-end DTI and a 45% back-end DTI to qualify borrowers.
This is by design and speaks to the core differences in FHA vs. conventional loans. The FHA loan program is geared toward borrowers who are perceived as being higher risk. That includes borrowers with lower credit scores or smaller down payments. Conventional loans, meanwhile, tend to favor borrowers who are financially stable with larger down payments and higher credit scores.
One caveat regarding FHA loans is that while you may be able to qualify with a higher DTI, you’re required to pay a mortgage insurance premium (MIP) for the life of the loan. These premiums act as an insurance policy for the lender if you default on the loan. Conventional loans typically don’t require private mortgage insurance if you can afford to make a down payment of 20% or more.
How to Calculate DTI for FHA Loan
To find your back-end DTI ratio for a FHA loan, you’ll need to add up all of your monthly housing payments (current mortgage or rent, insurance, property taxes if applicable) and then add to that your other debt payments, including student loans, credit cards, and auto loans. Alimony is also included in DTI if you are paying it.
Next, you’ll calculate your gross monthly income from all sources. Gross income is all the money you make each month before deductions for taxes, retirement account contributions, and other amounts your employer takes out of your paycheck. It isn’t your net pay, or what you get to keep each pay period. So, why use gross pay versus net pay? The FHA follows this rule to simplify calculations and make them more uniform for lenders.
Once you have both numbers, you’ll divide your total monthly debt by gross monthly pay, then multiply the result by 100. The final number is your FHA back-end DTI. (Your front-end DTI ratio is just your housing payments divided by your gross monthly income. When qualifying you for a loan, the lender will do a front-end DTI calculation that factors in the costs of your potential mortgage payment, property taxes, and MIP associated with the new home.)
Here’s an example of a basic DTI calculation for FHA loans:
$1,500 monthly debt payments / $5,000 gross monthly income = 0.3 x 100 = 30% DTI
How to Lower Your DTI to Qualify for an FHA Loan
There are several ways to improve your DTI to increase your chances of qualifying for an FHA loan. Paying down debt is an obvious solution, but you may also consider shopping around for a less expensive home or working on your credit score. Increasing your income could also help to bring your DTI into an acceptable range for an FHA lender.
Pay Down Debts
Paying down debt may be the fastest way to improve your DTI ratio. If you can eliminate one or two debt payments, that shrinks the amount of your gross pay that you have to commit to debt each month. “One go-to way to pay off debt is the snowball method,” says Brian Walsh, CFP® and Head of Advice & Planning at SoFi. “You pay off your smallest balance first, while keeping up with minimum payments on other debt. The benefit is seeing some of your debt paid off sooner.”
Here’s a little more detail about the snowball method: In this debt payoff method, you first rank your debts from lowest balance to highest. You pay as much as you can toward the smallest debt, while making minimum payments to everything else. Once you pay off the first debt, you roll its payment over to the next one on the list. You continue rolling over payments until your debts are gone.
You could also consider consolidating debts with a loan, though that has its pros and cons. When you consolidate, you can pay off all your debts in one go and have just one payment to make. If the new monthly payment is lower, that could help improve your DTI ratio. However, applying for a loan could knock a few points off your credit score, which could hurt when it’s time to apply for a mortgage.
Find a Lower Home Price
Shopping for a less expensive home could help to improve your front-end DTI if your monthly mortgage payment ends up being reduced. Just how much lower you’ll need to go can depend on your income, credit scores, and debts. This option may be less realistic if your local housing market is tight, however, and there are fewer reasonably priced homes to go around.
If you can’t find a less expensive home, you might think about increasing your down payment. The more you pay toward the home upfront, the less you need to borrow. You could also use a larger down payment as a compensating factor to help offset a higher FHA DTI.
Improve Your Credit Score
Improving your credit score could add a compensating factor into the mix and potentially allow you to qualify for an FHA loan with a DTI ratio that is on the higher side. Some of the most effective ways to improve credit scores include paying bills on time, reducing debt, leaving older credit accounts open, and limiting how often you apply for new credit.
You may consider strategically raising your credit limits to improve your credit scores. Raising your limits, without adding to your balances, can help your credit utilization ratio. This ratio, which is the second-most important factor in credit scoring, measures how much of your available credit you’re using at any given time.

The Takeaway
Understanding the importance of your debt-to-income ratio matters if you’d like to use an FHA loan to buy a home. You don’t want to receive a surprise denial because you have too much debt, relative to your income, in the eyes of the lender. Calculating your DTI and looking into ways to improve this ratio, either by paying down debt or shopping for a different home, can give you a better shot at getting approved for a loan. Remember to compare mortgage rates carefully to find the best loan for your needs.
SoFi offers a wide range of FHA loan options that are easier to qualify for and may have a lower interest rate than a conventional mortgage. You can down as little as 3.5%. Plus, the Biden-Harris Administration has reduced monthly mortgage insurance premiums for new homebuyers to help offset higher interest rates.

FAQ
What is the max DTI for FHA loans in 2025?
The max front-end DTI for FHA loan approvals in 2025 is 31%. The maximum DTI on the back-end for FHA loans is 43%. It’s possible to get approved with a DTI up to 50% if you have compensating factors, or up to 55% if you go through an automated underwriting system (AUS).
Can I get approved for an FHA loan with a 55% DTI?
It’s possible to get approved for an FHA loan with a 55% DTI if you have strong compensating factors and/or go through automated underwriting. Automated underwriting means that a software program, not a human, looks at your application to determine whether to approve you for a loan.
Does FHA count student loans in DTI?
Student loans count toward your FHA max DTI calculations. That includes payments you make to federal student loans and to private loans. Refinancing student loans could result in a lower payment and leave you with fewer overall loans to repay, though it could result in a temporary drop in your credit scores.
How do lenders verify income for DTI?
Lenders can verify income for DTI using your tax returns and pay stubs. If you’re self-employed, you may be asked for a copy of your most recent profit-and-loss statement or cash flow statement. Lenders can also use bank statements to review direct deposits.
Can I include rental income or side income in my DTI for an FHA loan?
Rental income and money you earn through a second job or side hustle can be included in your total income when calculating DTI for FHA loans. You’ll need to provide documentation of each type of income you have to show to the lender so they can verify it for their records. If you make money doing gig work, for example, then you can share copies of 1099s to document your earnings.
