Your debt-to-income (DTI) ratio compares your monthly debt payments to your earnings. Learn what debt-to-income ratio you need for a mortgage.
At-A-Glance
- Your debt-to-income (DTI) ratio includes front-end DTI (how much of your income goes to housing costs) and back-end DTI (how much of your income goes to all other debts).
- DTI is a crucial factor in mortgage applications, and lenders set different DTI thresholds for approval.
- Depending on the lender, you may be approved with a front-end DTI ratio between 28%-36% and a back-end ratio between 36%-50% or higher.¹
When you apply for a mortgage, lenders zoom in on your finances — and your debt-to-income (DTI) is often under the spotlight. DTI compares your monthly debt payments to your gross monthly income and helps lenders assess whether adding a home payment seems realistic or risky. Knowing your DTI is also helpful for understanding how much space you have for a mortgage payment alongside everyday bills like student loans, car loans, and credit card payments.
The good news is that you can lower your DTI with responsible borrowing and budgeting habits. Let’s cover which DTI ratio lenders usually want to see and simple ways to bring yours down.
How to Calculate Your Debt-to-Income (DTI) Ratio
To find your front-end DTI, add up all your current monthly housing payments. For your back-end ratio, add up all other monthly debt payments (credit cards, car loans, student loans, etc.) plus your housing payments. These are your ongoing, predictable bills that lenders focus on across different types of mortgage loans, so you can skip everyday spending like groceries, gas, and subscriptions when calculating DTI.
Next, divide each total by your gross monthly income before taxes. This step gives you a decimal, so you’ll need to multiply by 100 to convert it into a percentage. That final percentage is your DTI.
(Monthly debt payments / gross monthly income) X 100 = DTI Ratio
| A real-life DTI calculation | ||||
| Gross monthly income | Rent/projected mortgage payment | Car loan payment | Student loan payment | Minimum credit card payment |
|---|---|---|---|---|
| $6,000 | $1,600 | $220 | $150 | $175 |
| Front-end DTI (housing only) | Back-end DTI (all debt) |
|---|---|
| $1,600 ÷ $6,000 = 0.266 | $2,145÷ $6,000 = .3575 |
| 26.6% | 35.75% |
A back-end DTI around 36% fits super well with most conventional loans, while a ratio as high as 45% (with savings or great credit) may still work for many conventional options.2 Seeing the percentage spelled out can help you tell which loan types line up with your real-life numbers — and whether a little debt cleanup could make a big difference.

What Is a Good Debt-to-Income Ratio For Mortgages?
Most conventional mortgage lenders prefer a back-end DTI ratio around 36%, so if your DTI is below this, you are in relatively good shape.3 However, some loans, such as those that Federal Housing Administration (FHA) backs, may allow back-end ratios up to 50% and, in some VA-loan cases, even higher for well-qualified borrowers.4
Still, you don’t have to say goodbye to your dream of owning a home if your DTI isn’t ideal, because lenders also consider other factors like credit score, how much you have in savings, and down payment size when assessing your eligibility as well.
To position yourself for higher approval odds, you can take these steps:
- Calculate Your DTI
Compare your total monthly debt payments to your gross monthly income before applying.
- Explore All Loan Options
Different loan types have varying DTI requirements, and a little research can help you narrow down the best fit for your current financial situation. - Consider a Co-Signer
If your DTI is high, you may want to consider having a financially stable, trustworthy friend or family member co-sign your application. Lenders will evaluate the co-signer’s DTI, potentially increasing your borrowing power or lowering your interest rate. Just remember that your co-signer is almost always on the hook if you can’t make payments.
How to Lower Your DTI Ratio for Mortgage Applications
Improving your DTI ratio can help up your mortgage approval odds and the chance of receiving better mortgage terms.
Here are some tips to help you lower your DTI:
- Pay Down High-Interest Debts
Focus on paying down debts with the highest interest rates first, as they cost you the most money over time.
For example, if you had credit card debt, auto loan debt, and student loan payments, you could prioritize your debts as follows, paying off the highest-interest debt first:
| Type of Debt | Interest |
|---|---|
| Credit card | 22% |
| Auto loan | 10% |
| Student loan | 6% |
- Make Additional Principal Payments
Whenever possible, make extra payments toward the principal balance of your loans. This decreases the total interest accrued and shortens the loan term.
- Consider Debt Consolidation
If you have multiple debts, consolidating them into a single loan with a lower interest rate might cut down your monthly payments, helping to lower your DTI.
Remember, reducing your expenses is just one side of the equation.
Here are some short and long-term options to think about for increasing your income:
- Consider Your Employment
If you’ve been excelling at your job, it might be time to negotiate a higher salary. Alternatively, explore the job market for positions that offer better compensation.
- Take on a Part-Time Job or Freelance Work
Diversifying your income sources could improve your income and DTI. Look for opportunities that fit your availability and skillset.
- Invest in Your Education or Professional Development
Acquiring new skills or certifications might lead to promotions or open doors to higher-paying roles.
By striking a balance between earning more and reducing debt, you’ll be on the right track to lowering your DTI and getting approved for a mortgage that works for your needs.
Frequently Asked Questions
Your debt-to-income ratio is a separate metric that does not directly influence your credit score range. Rather, your debt-to-credit ratio, or credit utilization ratio, influences your scores. However, lenders evaluate your DTI as part of their overall criteria for extending new credit or loan products.5
When it comes to DTI, lower is better. However, lenders may set their own requirements. As an example, if your DTI ratio is closer to 45% than 35%, other factors, such as a substantial down payment or a high credit score, may help improve your eligibility, depending on the loan in question.6
Before applying for a mortgage, assess your credit score, debt-to-income ratio, and how much you can afford for a down payment to get an idea about your eligibility. Any supplemental income, savings, or potential co-signers are also important to consider.
The Takeaway
Understanding what debt-to-income ratio you need for a mortgage can give you a good idea about your approval odds. However, different lenders have different requirements, so be sure to shop around to find an option that works for you.
