How does my DTI affect my mortgage application?
Your debt-to-income ratio compares your monthly debt obligations with your income. It shows the percentage of your income that must go toward bills each month, which helps lenders evaluate whether you can afford the monthly payments on a mortgage.
Al Murad, the executive vice president of consumer direct sales at the lender AmeriSave Mortgage, advised that you can be rejected for a new mortgage if lenders consider your DTI ratio "high-risk."
DTI requirements for conventional mortgages
According to the Legal Information Institute at Cornell Law School, most lenders of conventional mortgages like to see your housing debt come in under 28% of your income and your total DTI ratio under 36% of your total gross income. However, there are situations where you can still get approved for a home loan with a higher DTI ratio.
Aim for a DTI ratio of 36% or lower for the best chance of mortgage approval.
Murad, the vice president at AmeriSave Mortgage, pointed out that conventional loans may have a maximum DTI ratio of 45% to qualify, depending on the lender. And even then, there are situations where a higher percentage could work.
"Borrowers with a DTI ratio of 50% may still qualify for a conventional loan if they have a high credit score and large cash reserves," he said.
DTI requirements for other loan types
Some government-backed home loans — including Federal Housing Association (FHA) loans in some cases — have higher DTI maximums. Murad said FHA loans allow a DTI ratio of up to 31% for housing costs and a total DTI ratio of up to 50% with all types of debts and required monthly payments.
U.S. Department of Agriculture (USDA) loans, which are designed for eligible rural and suburban homebuyers, typically follow a 29% cap for housing costs and a 41% total DTI ratio. However, lenders may approve higher DTIs if the borrower has strong compensating factors, such as a higher credit score or cash reserves.
Department of Veterans Affairs (VA) loans for eligible veterans and active-duty military don't necessarily have a DTI maximum, he said. However, a DTI ratio above 41% could delay the approval process or lead to a higher mortgage interest rate.
"The VA doesn’t establish a maximum DTI ratio but uses it as a measure to help lenders," Murad said.
Ultimately, you may be denied a home loan if your DTI ratio is too high. You may have to consider other home loan products to find financing you can qualify for.
How does DTI affect my mortgage rate and loan terms?
Your DTI ratio doesn’t just affect whether you’re approved for a mortgage but can also influence the cost and terms of your loan. Lenders use DTI to judge how easily you can handle monthly payments, and higher DTIs usually mean higher risk.
- Mortgage interest rate: Borrowers with lower DTIs often qualify for better interest rates. A higher DTI can lead to a higher rate because the lender sees more risk of missed payments.
- Down payment requirements: If your DTI is on the higher end, a lender may require a larger down payment to reduce their risk.
- Private mortgage insurance (PMI): For conventional loans, a higher DTI can make PMI more expensive or harder to remove, since lenders rely on it to offset added risk.
- Loan fees and pricing adjustments: Some lenders charge higher upfront fees or apply pricing adjustments when a borrower’s DTI exceeds certain thresholds.
- Loan flexibility: A lower DTI may give you access to more loan options or flexible terms, while a higher DTI can limit your choices.
Front-end vs. back-end DTI ratios: What’s the difference?
When lenders look at your debt-to-income ratio, they often break it into two parts: front-end DTI and back-end DTI. Both help lenders understand how much of your income goes toward housing and other debts.
- Front-end DTI: This measures how much of your gross monthly income goes toward housing costs alone. These costs typically include your mortgage payment, property taxes, homeowners insurance and, if applicable, HOA fees.
- Back-end DTI: This looks at your total monthly debt payments, including housing costs plus things like auto loans, student loans, credit cards and personal loans.
In the mortgage process, lenders usually focus more on back-end DTI, since it shows your full debt picture. However, some loan programs also set limits on front-end DTI, especially for government-backed loans.
How do I calculate my DTI?
To calculate your back-end debt-to-income ratio, add up all your monthly debt payments, then divide the total by your gross monthly income.
For example, let's say you have the following bills each month:
- Monthly rent payment: $1,600
- Auto loan: $450
- Credit card minimum payments: $350
- Total: $2,400
If your gross monthly income is $6,000, you would divide 2,400 by 6,000 to get 0.40. To convert that number to a percentage, multiply it by 100. Your DTI ratio in this scenario is 40%.
If you want to calculate your front-end DTI ratio, perform the same calculations using only your monthly housing costs. In this example, your front-end DTI would be approximately 27%.
How can I lower my DTI?
If you applied for a mortgage but found out your DTI is too high, or you worry it will be, there are steps you can take to lower it or get approved for a mortgage through other means.
- Pay down credit cards and other revolving debt. Paying off credit cards and other debt is a solid way to lower your DTI ratio. By paying more than the minimum payment on credit card balances, you can reduce your minimum payment amount in subsequent months and lower your DTI ratio that way.
- Pay off any existing loans. Paying off outstanding loans also lowers your DTI ratio. For example, paying off an auto loan with a $450 monthly payment can lower your DTI in one fell swoop.
- Increase your down payment amount. Saving up more money for a home purchase can lower the amount you need to borrow, reducing your monthly housing payment and making it easier to qualify.
- Increase your income. If you can earn more money without increasing your monthly debt payments, this will lower your DTI ratio.
- Choose a less expensive home. Shopping for homes in a lower price range can help you get a lower monthly housing payment, dropping your DTI ratio for the new loan amount and payment.
- Stop adding new debt. Finally, quit adding to the pile while you're trying to lower your DTI ratio. "Don’t take out any new debt until more of the existing debt has been paid down," Murad advised.
What to do if your DTI is still too high for a mortgage
If your DTI ratio is still too high, but you need a mortgage soon, you can explore a few different strategies. For example, you may qualify for an FHA loan with a higher DTI ratio if you can get a co-signer.
Alternatives like an FHA loan might be a good choice if your DTI is too high.
You can also consider restructuring some of your debts to get a lower monthly payment that helps with your DTI ratio. For example, say you have credit card debt with high interest rates and a big payment each month. Transferring that debt to a new balance transfer credit card with 0% APR for a limited time could help you lower your monthly debt payments and your DTI ratio.
Finally, you could consider "paying points" on your mortgage. With this strategy, you pay an upfront fee to get a lower mortgage rate, thus lowering your new housing payment and your DTI ratio.
You can also improve your financial situation before applying for a mortgage. This typically means paying off debt and saving up a larger down payment until you're in a position to qualify for a home loan with the best rates and terms.

FAQ
What monthly payments are not included in my DTI?
Generally speaking, monthly payments that don’t count toward your DTI include monthly utility bills, car insurance and health insurance expenses, cable bills, cellphone bills, groceries and entertainment expenses.
What sources of income are considered when applying for a mortgage?
Income considered when you apply for a mortgage can include your paycheck (hourly or salaried), self-employment income, military income, Social Security income, rental or property income and other gains you receive regularly.
Do I list my credit card minimum payments or the amount I typically pay?
When calculating your DTI ratio, you only need to include the required minimum payments on the credit cards you have.
Does a mortgage count against debt-to-income ratio?
Yes, your expected monthly mortgage payment, including principal, interest, property taxes, homeowners insurance and any HOA fees, is included in your DTI calculation. For buyers, this amount is added to your other monthly debts to determine whether you qualify for the loan.
How much is too much debt for a mortgage?
It depends on the loan type, but many lenders prefer a total DTI of 36% or lower for conventional loans. Some government-backed loans allow higher DTIs, often up to 41% to 50% in certain cases. Even when higher DTIs are allowed, having less debt usually leads to better rates and more loan options.
Why do DTI calculations use gross income and not net income?
DTI calculations use gross income (your income before taxes and other deductions) rather than net income because lenders want a consistent and standardized measure of a borrower’s ability to repay a loan. Gross income is predictable and verifiable through pay stubs or tax returns, whereas net income can vary widely due to taxes, retirement contributions and other deductions.
