What Is a Good Debt-to-Income Ratio?
The single number lenders look at most closely — and one worth knowing even if you're not applying for anything right now.
What it actually measures
Debt-to-income (DTI) ratio compares your total monthly debt payments (mortgage or rent, car loans, student loans, minimum credit card payments) to your gross monthly income, expressed as a percentage. It measures how much of your income is already committed to debt obligations before anything else.
Common benchmark ranges
| DTI Range | Generally considered |
|---|---|
| Under 36% | Healthy, most lenders view favorably |
| 36–43% | Manageable, but getting tighter |
| 43–50% | Many lenders' upper limit for approval |
| Above 50% | Financially stretched, limited borrowing room |
These are common reference points, not universal rules — specific lenders and loan types set their own actual cutoffs.
Two versions of DTI worth knowing
Front-end DTI: just housing costs (mortgage/rent, taxes, insurance) divided by income.
Back-end DTI: all debt payments combined divided by income — this is the number most lenders weigh most heavily for approval decisions.
How to actually improve it
- Pay down existing debt balances, particularly anything with a required minimum payment
- Avoid taking on new debt payments before a major application (like a mortgage)
- Increase income — since DTI is a ratio, growing the denominator helps just as much as shrinking the numerator
- Refinance existing debt to a lower monthly payment, if the terms genuinely improve your situation

Does DTI affect my credit score directly?
Not directly — DTI is a separate calculation lenders use during underwriting, though high credit utilization (a related but distinct concept) can affect your credit score.
Is rent included in DTI if I don't own a home?
Yes, for renters, monthly rent typically counts in place of a mortgage payment when a lender calculates front-end DTI.
