What this calculator does

Your debt-to-income (DTI) ratio compares how much you pay toward debt each month with how much you earn. This calculator divides your monthly debt payments by your gross monthly income and shows the result as a percentage, along with the risk band lenders typically use.

How to use it

  1. Enter your total monthly debt payments.
  2. Enter your gross monthly income.
  3. Read your debt-to-income ratio and its risk band below.

A worked example

If you pay 1,800 toward debt each month and earn 5,000, your DTI is 1,800 / 5,000 × 100 = 36%, which sits at the top of the healthy band.

What the bands mean

  • 36% or less: healthy. Lenders usually see this as comfortable.
  • 37–43%: caution. Manageable, but there is less room for new borrowing.
  • Above 43%: high. Many lenders treat this as a warning sign.

When it's useful

Checking your finances before applying for a loan or mortgage, planning a budget, or deciding whether to take on new debt.
