Debt-to-Income (DTI) Ratio
The percentage of your gross monthly income that goes toward paying monthly debt obligations.
Plain-English Explanation
Your Debt-to-Income (DTI) ratio is a metric lenders use to measure your financial health and capacity to handle additional loan debt. Front-End DTI calculates housing expenses relative to gross income, while Back-End DTI includes ALL recurring debts (housing, minimum credit cards, auto loans, student loans).
Gross monthly income is your pre-tax total monthly earnings from all sources.

Why Debt-to-Income (DTI) Ratio Matters for Your Finances
Lenders enforce strict DTI limits for mortgage approval. Most conventional home loans cap DTI at 36% to 43%, while FHA loans may allow up to 45%-50% with compensating factors.
Common Misconception
DTI does not include living expenses like groceries, utilities, health insurance, or gas—only contractually required minimum debt payments.
