What is Debt-to-Income Ratio?
Debt-to-Income Ratio (DTI) measures what percentage of your monthly income goes toward debt payments — a critical metric lenders use to assess your financial health. It is calculated by dividing your total monthly debt payments by your gross monthly income. The lower your DTI, the more creditworthy you appear as a borrower.
Debt-to-Income Ratio (DTI) = total monthly debt payments ÷ gross monthly income × 100. A lower DTI indicates better financial health and increases chances of loan approval.

Step-by-step worked examples
Monthly gross income $4,000, total monthly debt payments $800. Calculate DTI.
DTI = ($800 ÷ $4,000) × 100 DTI = 0.20 × 100 DTI = 20%
Income $5,500, credit card $300 + student loan $450 + mortgage $1,200. Find DTI.
Total debt = $300 + $450 + $1,200 = $1,950 DTI = ($1,950 ÷ $5,500) × 100 DTI = 35.5%
Income $2,800, debt $336 per month. Calculate DTI.
DTI = ($336 ÷ $2,800) × 100 DTI = 0.12 × 100 DTI = 12%
