What is Debt-to-Income Ratio?
Understanding the key metric lenders use to evaluate your loan applications
Your debt-to-income (DTI) ratio is a percentage that shows how much of your monthly gross income goes toward paying debts. Lenders use this number to assess your ability to manage monthly payments and repay borrowed money.
The Formula
DTI Ratio = (Total Monthly Debt Payments ÷ Gross Monthly Income) × 100
Example: If you earn $5,000/month and pay $2,000/month in debts, your DTI is 40% ($2,000 ÷ $5,000 × 100).
Two Types of DTI Ratios
Front-End Ratio
Measures only housing-related expenses (mortgage/rent, property taxes, insurance, HOA fees) as a percentage of income.
Ideal Range: Below 28%
Back-End Ratio
Includes all monthly debt obligations: housing, auto loans, student loans, credit cards, and other debts.
Ideal Range: Below 36%
Why Your DTI Matters for Loans
Loan Approval
Most lenders have maximum DTI requirements. Conventional mortgages typically require DTI below 36%, while FHA loans allow up to 43%.
Interest Rates
Lower DTI ratios often qualify for better interest rates, potentially saving you thousands over the life of a loan.
Loan Amount
Your DTI directly affects how much you can borrow. Lower ratios mean you may qualify for larger loan amounts.
Financial Health
Even beyond loans, DTI is an excellent indicator of your overall financial health and sustainability.

|---|---|---|---|
| Conventional Mortgage | 28% | 36% | Most strict requirements |
| FHA Loan | 31% | 43% | First-time homebuyers |
| VA Loan | 41% | 41% | Military/veterans only |
| USDA Loan | 29% | 41% | Rural properties |
