Understanding Debt-to-Income Ratios and Why They Matter

When you apply for a mortgage, lenders don’t just look at how much money you make—they also look at how much debt you already have. One of the most important ways they measure this is through your debt-to-income ratio, or DTI.

What Is Debt-to-Income Ratio?

Your debt-to-income ratio is a simple calculation that compares your monthly debt payments to your gross monthly income (that’s your income before taxes).

DTI Formula: Total Monthly Debt Payments ÷ Gross Monthly Income = DTI Percentage

For example, if you pay $2,000 a month toward debts (like credit cards, auto loans, student loans, and your projected mortgage) and your gross monthly income is $6,000, your DTI is 33%.

What Counts as Debt in DTI?

When calculating your DTI, lenders typically include:

• Proposed monthly mortgage payment (including property taxes, homeowners’ insurance, monthly mortgage insurance and any HOA dues)
• Car loans or leases
• Minimum credit card payments
• Student loan payments
• Personal loans
• Alimony or child support (if applicable)
• IRS repayment plans or other tax payment obligations

Debts such as utilities, cell phone bills, groceries, insurance premiums (outside of homeowners insurance), gas, and other day-to-day living expenses are not included in DTI.

While these regular expenses affect your overall budget, lenders focus strictly on fixed, recurring debt obligations when calculating your DTI.

Additionally, lenders will review your bank statements and other documentation to identify any undisclosed debts—these are obligations that might not appear on your credit report but can still impact your qualification and must be accounted for.

What Is a Good Debt-to-Income Ratio?

Every loan program has different DTI limits. Here’s a breakdown of common guidelines based on loan type:

• Conventional Loans: Typically require a DTI of 43% or lower, though some programs allow up to 50% with strong compensating factors.
• FHA Loans: Can go as high as 56.9% in certain cases, especially if the borrower has strong credit, significant reserves, or other positive factors.
• VA Loans: No official DTI cap, but 41% is the benchmark. Higher ratios are allowed with sufficient residual income.
• USDA Loans: Generally capped around 41%, though exceptions can be made for borrowers with strong credit profiles.
• Jumbo Loans: Typically capped around 43% to 45%, though this can vary by lender and the borrower’s overall financial strength.

These percentages aren’t hard limits but general guidelines. My team and I can help you understand what ratio applies to your situation and explore options if you’re on the higher end.

Why Does DTI Matter?

DTI matters because it gives lenders a sense of your ability to manage monthly payments alongside your existing debts. A lower DTI suggests you’re less likely to overextend yourself, making you a safer borrower.

Plus, knowing your DTI helps you personally assess what payment is comfortable versus what you might technically qualify for on paper. Just because a lender approves you for a certain amount doesn’t mean that payment will align with your lifestyle.

How to Improve Your DTI

If your DTI is higher than what your loan program allows, there are several strategies that might help reduce it:

• Pay off or reduce existing debts, especially credit cards. Always check with your lender before paying off any debts, as it could affect your credit profile or available reserves.
• Avoid taking on new debt before applying for a mortgage.
• Consider a lower home price to keep your mortgage payment manageable.
• Potentially refinance an auto loan to reduce your monthly payment amount.
• Consider adding a co-signer if the loan program allows for it.

Additionally, if you have any installment loans with fewer than 10 payments remaining, those payments may be excluded from your DTI calculation, potentially improving your ratio.

DTI isn’t static—it can shift quickly if your financial situation changes, like taking on new debt, switching jobs, or making large purchases. Keeping your finances steady while you’re preparing for or actively buying a home is crucial.
