Debt-to-Income Ratio Calculator

What Is a Debt-to-Income (DTI) Ratio?

Your debt-to-income ratio (DTI) is a key financial metric that compares your total monthly debt payments to your gross monthly income. It is expressed as a percentage and is used by lenders to assess your ability to manage monthly payments and repay debts. A lower DTI indicates a healthier balance between debt and income.

This calculator quickly computes your DTI, shows you where you stand, and provides guidance on what the numbers mean for your financial goals, such as getting a mortgage or a personal loan.

How to Use This DTI Calculator

1. Enter your Monthly Gross Income — your total earnings before taxes and deductions.
2. Enter your Total Monthly Debt Payments — include credit cards, auto loans, student loans, personal loans, and any other recurring debt obligations.
3. Click Calculate to see your DTI percentage, a visual gauge, and a detailed breakdown.

You can adjust the numbers to see how paying off debt or increasing income can improve your DTI.

How the Calculation Works

• DTI Formula: (Total Monthly Debt Payments / Gross Monthly Income) × 100
• Interpretation:
  • ≤ 36% — Excellent: You have a healthy balance and are likely to qualify for favourable loan terms.
  • 37% – 42% — Fair: You may be able to manage, but consider reducing debt before applying for large loans.
  • ≥ 43% — Poor: Lenders may see you as high-risk; work on paying down debt.
• The calculator also shows your remaining income after debt payments, helping you see how much you have left for other expenses and savings.
