Debt-to-Income Ratio — Definition and What It Means for Your Income

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

Debt-to-income (DTI) ratio is calculated by dividing total monthly debt payments (student loans, car payments, credit cards, mortgage/rent) by gross monthly income. Lenders use DTI to assess loan eligibility.

Why it matters

DTI is a key factor in mortgage approval and reveals how much of your income is already committed before discretionary spending and savings.

Example

Someone with $6,000/month gross income and $1,800/month in total debt payments (including rent) has a DTI of 30% — generally considered healthy for most lending purposes.
