Debt-to-Income Ratio (DTI)

Quick Answer

The percentage of monthly gross income that goes toward debt payments.

Definition

The percentage of monthly gross income that goes toward debt payments.

Explanation

DTI = (Total Monthly Debt Γ· Gross Monthly Income) Γ— 100. Lenders use DTI to determine mortgage affordability. A DTI under 36% is preferred. Includes: proposed mortgage, car loans, student loans, credit cards. Excludes: utilities, groceries, insurance.

Lower DTI means more income available for housing. Paying down debts before buying a home can significantly improve your budget.

Example

$7,000 income, $1,700 existing debts = 24.3% DTI. Adding $1,960 mortgage = total $3,660, DTI = 52.3% (too high for most lenders).
