What the Numbers Mean

  • 36% or less — healthy; most lenders approve comfortably.
  • 36% to 43% — borderline; you may qualify with a strong credit history.
  • Above 43% — high; most conventional and FHA loans won't approve without co-signers or debt reduction.

Formula

DTI = (Total monthly debt payments ÷ Gross monthly income) × 100

Worked Example

Gross income $6,000, housing $1,500, car $400, cards $100, other $0: DTI = ($2,000 ÷ $6,000) × 100 = 33.3% — a healthy ratio within most lender limits.

Frequently Asked Questions

What is a good debt-to-income ratio?
Most lenders prefer a total DTI ratio of 36% or less. Ratios between 36% and 43% are acceptable to many lenders, while anything above 43% usually makes it hard to qualify for a mortgage. For FHA loans, the typical cap is 43%.
What is the difference between front-end and back-end DTI?
Front-end DTI looks only at your housing costs (rent or mortgage, taxes, and insurance) divided by gross income. Back-end DTI includes all monthly debt payments: housing, car loans, student loans, and credit-card minimums. Lenders focus on back-end DTI.
Which payments count toward DTI?
Lenders count your housing payment, car and personal loans, student loans, credit-card minimums, alimony and child support, and other installment debt. Costs like utilities, groceries, and insurance that aren't part of your mortgage payment are usually excluded.
How can I lower my debt-to-income ratio?
Pay down balances, pay off or consolidate high-interest debts, avoid taking on new loans, or increase your income. Even raising your gross income with a side job lowers DTI without changing your debt.
Does DTI affect my credit score?
No. Your credit score and DTI are separate measures. DTI compares your income to your debt load and is used mainly for loan underwriting, while your score reflects your repayment history and credit usage.
Why do lenders use DTI instead of just my credit score?
A credit score measures how reliably you've repaid debt in the past. DTI measures whether you can realistically afford a new monthly payment today. Lenders use both to size the loan you qualify for.
