Overview
Debt-to-Income Ratio (DTI) is a key financial metric that lenders use to assess a borrower's ability to manage monthly debt payments. It is calculated as the percentage of a borrower's monthly gross income that goes toward paying debts, including mortgage payments, credit card payments, auto loans, student loans, and other recurring debt obligations.
How DTI is Calculated
DTI = (Total Monthly Debt Payments / Monthly Gross Income) × 100%
To illustrate, if your monthly gross income is $5,000 and your total monthly debt payments are $1,500, your DTI would be 30%.
Front-End vs Back-End DTI
- Front-End DTI: Only includes housing-related expenses (mortgage principal, interest, taxes, insurance, HOA fees). Typically limited to 28%.
- Back-End DTI: Includes all monthly debt payments. Typically limited to 36% for conventional loans.
DTI Requirements for Mortgages
- Conventional loans: 28% front-end, 36% back-end
- FHA loans: Up to 31% front-end, 43% back-end
- VA loans: Up to 41% back-end
- USDA loans: Up to 29% front-end, 41% back-end
