What is a Debt-to-Income (DTI) Ratio?
Your Debt-to-Income (DTI) ratio is a personal finance measure that compares your total monthly debt payments to your gross monthly income (your income before taxes and deductions). Lenders use this ratio as a primary indicator of your ability to manage monthly payments and repay the money you plan to borrow.
Unlike your credit score, which measures your history of repaying debts, DTI measures your current capacity to take on new debt. It answers the lender's question: "Can they afford another monthly payment?"
Why Your DTI Ratio Matters
The DTI ratio is a critical factor in approvals for virtually all major types of credit, particularly mortgages and auto loans. A low DTI shows lenders that you have a good balance between debt and income. Conversely, a high DTI signals that you might be overleveraged and could struggle to make payments if your financial situation changes even slightly.
- Mortgage Approvals: Most conventional mortgage lenders prefer a DTI ratio no higher than 43%, though some government-backed loans (like FHA) may allow higher ratios with compensating factors.
- Interest Rates: A lower DTI can sometimes help you secure lower interest rates, saving you thousands of dollars over the life of a loan.
Understanding DTI Thresholds
While lender requirements vary, here are general guidelines for interpreting your DTI score:
- 35% or Less (Excellent): This is the ideal range. It indicates you have manageable debt and significant disposable income. Lenders view you as a low-risk borrower.
- 36% to 43% (Manageable): You likely still qualify for most loans, but you are approaching the upper limits of what many lenders prefer. You should be cautious about taking on new debt.
- 44% or Higher (High Risk): At this level, your debt obligations consume a large portion of your income. You may face difficulties getting approved for a mortgage or other significant loans, and you are more vulnerable to financial emergencies.
What Is Included in the DTI Calculation?
When calculating DTI, lenders look at your recurring monthly debts. The calculator above includes the standard categories used by financial institutions:
- Housing Costs: Your monthly rent or current mortgage payment (including principal, interest, taxes, and insurance).
- Installment Loans: Fixed monthly payments such as auto loans, student loans, and personal loans.
- Revolving Credit: The minimum required monthly payment on credit cards, lines of credit, or HELOCs (not the total balance).
- Other Obligations: Court-ordered payments like alimony or child support.
Note: Routine living expenses like groceries, utilities, gas, and entertainment are generally NOT included in the DTI calculation.
Tips to Lower Your Debt-to-Income Ratio
If your DTI is higher than you'd like, especially if you are planning to apply for a mortgage soon, take steps to lower it:
- Increase Your Income: Boosting your gross monthly income through a raise, a side hustle, or a higher-paying job will immediately lower your ratio, provided your debt remains the same.
- Pay Down High-Payment Debt: Focus on aggressively paying off debts with high monthly payments. Eliminating a $400 car payment has a bigger impact on DTI than paying down a large student loan balance with a low $150 monthly payment.
- Avoid New Debt: Do not open new credit cards or finance major purchases right before applying for a significant loan.
