Debt-to-Income Ratio Calculator

Your debt-to-income ratio, or DTI, compares your total monthly debt obligations to your gross monthly income. Lenders use this metric to estimate how comfortably you can take on additional loan payments. A lower ratio usually signals stronger borrowing capacity and lower risk.

This calculator includes common recurring debts such as housing, auto loans, student debt, credit cards, and other required monthly payments. As you adjust each field, your DTI updates instantly so you can test scenarios before applying for financing.

In general, keeping DTI under 36% improves approval odds for many loan products, while lower is even better. If your ratio is high, consider reducing balances, refinancing expensive debt, or increasing income before submitting a mortgage or personal loan application. Exact thresholds differ by lender and loan type, but this tool gives you a practical benchmark for planning and financial readiness.

Tracking DTI over time can also support broader financial goals beyond loan approval. A lower ratio often improves monthly flexibility, making it easier to save for emergencies and long-term investments. Use the breakdown chart to identify which payment categories are driving the most pressure and where targeted debt reduction can produce the biggest improvement.
