1. What is Backend Debt Ratio?

The Backend Debt-to-Income (DTI) ratio is a financial metric that compares your total monthly debt payments (including housing expenses) to your gross monthly income. It's used by lenders to assess your ability to manage monthly payments and repay debts.

2. How Does the Calculator Work?

The calculator uses the Backend DTI formula:

Where:

• \( Housing \) — Monthly housing expenses (mortgage/rent, insurance, taxes)
• \( Debt \) — Monthly debt payments (loans, credit cards, other obligations)
• \( Income \) — Gross monthly income (before taxes and deductions)

Explanation: The ratio shows what percentage of your income goes toward debt payments, helping lenders evaluate your financial health.

3. Importance of Backend DTI Calculation

Details: Lenders typically prefer a Backend DTI ratio of 36% or less, though some may accept up to 43%. A lower ratio indicates better financial stability and higher loan approval chances.

4. Using the Calculator

Tips: Enter all amounts in USD. Include all monthly housing costs and debt payments. Use gross monthly income (before deductions). All values must be positive numbers.
