What is Debt‑to‑Income Ratio?
The DTI ratio compares your total monthly debt payments to your gross monthly income. Lenders use it to evaluate your ability to manage new debt, especially mortgages.
💡 Key insight: A DTI below 36% is considered excellent, while above 50% signals high risk.
Why lenders use DTI
Lenders want to ensure you can afford additional monthly payments. A lower DTI means more disposable income and lower default risk.
How to improve your DTI
- Pay down credit card balances
- Refinance high‑interest loans
- Avoid new debt before mortgage application
- Increase income (side work, raises)
Mortgage approval tips
- Keep DTI ≤ 43% for most loans
- Save for a larger down payment
- Check your credit report
Example
| Item | Amount |
|---|---|
| Gross monthly income | $6,000 |
| Total monthly debt | $2,100 |
| DTI | 35% (Excellent) |
