What is Debt-to-Income Ratio?
Debt-to-Income (DTI) ratio is a personal finance measure that compares your monthly debt payments to your monthly gross income. It's expressed as a percentage and helps lenders determine how much of your income is already committed to debt repayment. A lower DTI ratio indicates better financial health and greater borrowing capacity.

Total Monthly Debt Payments = Sum of all monthly debt obligations
Gross Monthly Income = Total income before taxes and deductions

Delay New Debt
Avoid taking on new debt before major loan applications. Postpone large purchases that require financing.
Debt Snowball/Avalanche
Use debt repayment strategies to systematically eliminate debts, starting with smallest balance or highest interest rate.

- Utilities, insurance, and living expenses are NOT included in DTI calculation
- Some lenders may exclude certain debts if they'll be paid off soon
- Debts with less than 10 payments remaining may be excluded
- Co-signed loans count toward your DTI if you're the primary payer
- Rental property expenses may be offset by rental income
Frequently Asked Questions
What is a good DTI ratio?
Generally, a DTI below 36% is considered good, with 20% or lower being excellent. Most lenders prefer a back-end DTI of 43% or lower for qualified mortgages.
Is DTI calculated before or after taxes?
DTI uses gross monthly income (before taxes and deductions). Debts are your minimum monthly payments, not total balances.
How can I lower my DTI ratio quickly?
Pay off small debts completely, increase your income with overtime or side work, or consolidate high-interest debts into a lower payment.
Do lenders look at front-end or back-end DTI?
Lenders typically focus on back-end DTI (all debts), but also consider front-end DTI (housing costs) especially for mortgage applications.
