Advanced DTI Ratio Calculator

Calculate front-end and back-end debt-to-income ratios, analyze financial health, and visualize debt distribution for loan approval readiness.

How It Works

  • - Converts income into monthly value (if annual)
  • - Sums all monthly debt payments
  • - Identifies housing-related debt automatically
  • - Calculates front-end and back-end DTI ratios

Core Formulas

  • - Monthly Income = Annual Income / 12
  • - Front-End DTI = Housing Debt / Monthly Income × 100
  • - Back-End DTI = Total Debt / Monthly Income × 100
  • - Total Debt = Sum of all monthly payments

DTI Types

  • - Front-End DTI: Only housing expenses (mortgage, rent)
  • - Back-End DTI: All debts including loans, cards, etc.
  • - Lenders focus more on back-end ratio
  • - Both ratios help determine borrowing capacity

DTI Interpretation

  • - Below 36% → Healthy financial profile
  • - 36% – 43% → Moderate risk
  • - Above 43% → High risk (loan approval difficult)
  • - Lower DTI improves loan eligibility
