Real-World Examples

$2,400 in monthly debts, $6,000 income

Your DTI is 40%, which falls in an elevated range where some lenders start to hesitate.

What the ratio means

DTI = total monthly debt payments ÷ gross monthly income × 100. Lower is generally better. A ratio above 43% can make getting a mortgage harder, though every lender's rules differ.

Frequently Asked Questions

Does this include utilities or groceries?

No. DTI counts debt payments — rent or mortgage, car loans, student loans, credit cards, and similar obligations — not living expenses.

Is this the same ratio a lender uses?

It's a close approximation. Lenders may calculate two versions (front-end and back-end) and use your verified income and debts, which can differ from your estimates.

What's a good DTI?

Many lenders prefer a back-end ratio below 36%, with no more than about 28% going to housing. Lower is generally better, but requirements vary.
