What Is Debt-to-Income Ratio?
DTI = Monthly Debt Payments ÷ Gross Monthly Income
It tells lenders what percentage of your income goes toward debt. Lower is better.
Example
- Monthly income (gross): $6,000
- Mortgage payment: $1,500
- Car payment: $400
- Student loans: $300
- Credit card minimums: $100
- Total monthly debt: $2,300
- DTI = $2,300 ÷ $6,000 = 38%
Two Types of DTI
Front-End DTI (Housing Ratio)
Only includes housing costs (mortgage principal, interest, taxes, insurance).
Ideal: Under 28%
Back-End DTI (Total DTI)
Includes ALL monthly debt obligations.
Ideal: Under 36%
DTI Requirements by Loan Type
| Loan Type | Max DTI |
|---|---|
| Conventional | 45% (sometimes 50%) |
| FHA | 43% (sometimes 50%) |
| VA | 41% (flexible) |
| USDA | 41% |
While lenders may approve higher DTIs, a lower ratio gets you:
- Better interest rates
- Easier approval
- More loan options
DTI Benchmarks
| DTI Ratio | What It Means |
|---|---|
| Under 20% | Excellent — lots of financial flexibility |
| 20-35% | Good — manageable debt load |
| 36-43% | Acceptable — may qualify but stretched |
| 44-50% | Risky — limited options, higher rates |
| Over 50% | Dangerous — most lenders won't approve |
How to Lower Your DTI
Quick Wins

- Increase income — Side hustle, raise, second job
- Avoid new debt — Don't finance anything before applying for a mortgage
Longer-Term Strategies
- Pay down credit cards — Below 30% utilization

DTI Impact on Your Life
A high DTI doesn't just affect loan approval — it impacts your daily finances:
| DTI | Monthly Income $6,000 | Left After Debt |
|---|---|---|
| 20% | $1,200 debt | $4,800 remaining |
| 36% | $2,160 debt | $3,840 remaining |
| 43% | $2,580 debt | $3,420 remaining |
| 50% | $3,000 debt | $3,000 remaining |
At 50% DTI, half your income goes to debt before you've paid for food, gas, or utilities.
