Quick Answer
Debt-to-income ratio (DTI) is the percentage of your gross monthly income that goes toward debt payments. Lenders use DTI to assess your ability to take on additional debt. A lower DTI means you have more income available to handle new debt payments.
| DTI Range | Rating | What It Means |
|---|---|---|
| Under 20% | Excellent | Qualify for best rates on all products |
| 20%–35% | Good | Qualify for most products at competitive rates |
| 36%–43% | Acceptable | Qualify for most products; higher rates possible |
| 44%–50% | High | Difficult to qualify; limited options |
| Over 50% | Very High | Most lenders will deny. Focus on paying down debt first. |
What is a good debt-to-income ratio?
A DTI under 36% is generally considered good by most lenders. For mortgages, the maximum DTI is typically 43% (conventional) or 50% (FHA with compensating factors). For personal loans, most lenders prefer under 40%. The lower your DTI, the better your approval odds and rates.
Does DTI affect your credit score?
No. Your debt-to-income ratio does not directly affect your credit score. Credit scores don't include your income — they only measure how you manage debt. However, a high DTI can prevent loan approval even with a good credit score, because lenders use DTI to assess repayment ability.
What DTI do you need for a mortgage?
For a conventional mortgage, most lenders require a DTI under 43%. FHA loans allow up to 50% DTI with compensating factors (large down payment, high credit score). For the best mortgage rates, aim for a DTI under 36%. VA loans don't have a strict DTI limit but prefer under 41%.
How do I calculate my front-end vs back-end DTI?
Front-end DTI (housing ratio) = housing costs ÷ gross income. Includes mortgage/rent, property taxes, insurance, HOA. Most lenders want this under 28%. Back-end DTI (total DTI) = all debt payments ÷ gross income. Includes housing plus all other debts. Most lenders want this under 43%.
