What your DTI means

Your debt-to-income ratio is one of the first numbers a lender checks. It compares everything you owe each month against everything you earn before tax:

DTI = (total monthly debt payments ÷ gross monthly income) × 100

The lower it is, the more room you have to take on new borrowing safely. Lenders sort applicants into rough bands:

  • ≤ 36% — Good. Comfortable for most lenders.
  • 37–43% — Acceptable, but near the mortgage ceiling. 43% is often the maximum for a qualified mortgage.
  • 44–49% — High. Approval gets harder and you should expect extra scrutiny.
  • ≥ 50% — Very high risk. Focus on reducing debt before applying.

Use gross (pre-tax) income, not take-home pay, and include rent or mortgage, car payments, student and personal loans, and minimum credit-card payments. Utilities, groceries and insurance premiums are usually left out.
