Your debt-to-income ratio (DTI) is the percentage of your gross monthly income that goes toward paying debts. Lenders use it to evaluate whether you can handle additional loan payments.
DTI = Total Monthly Debt Payments ÷ Gross Monthly Income × 100
Example: $1,500 in monthly debts ÷ $5,000 gross income = 30% DTI
| DTI Range | Rating | What It Means |
|---|---|---|
| Below 20% | Excellent | Excellent financial health, best loan rates |
| 20% – 35% | Good | Manageable debt, easy loan approval |
| 36% – 43% | Acceptable | May qualify for mortgage but harder to approve |
| 44% – 50% | High | Difficult to get approved, high risk |
| Above 50% | Too High | Most lenders will deny application |
| Loan Type | Maximum DTI | Ideal DTI |
|---|---|---|
| Conventional Mortgage | 45-50% | Below 36% |
| FHA Loan | 57% | Below 43% |
| VA Loan | 41% (guideline) | Below 36% |
| Personal Loan | 40-50% | Below 35% |
| Auto Loan | 50% | Below 40% |
Mortgage lenders actually look at two DTI ratios:
Gross monthly income: $6,000
| Action | Monthly Debt Reduction | DTI Impact (on $5k income) |
|---|---|---|
| Pay off $5,000 credit card | -$150/month min payment | -3% DTI |
| Pay off car loan ($10k) | -$350/month | -7% DTI |
| Side job ($800/month more) | Income increase | -5% DTI |
| Refinance student loans | -$150/month | -3% DTI |
Once you know your DTI, see what mortgage payment fits your budget.

Add up all your monthly debt payments (mortgage/rent, car loans, student loans, credit card minimums, personal loans). Divide by your gross monthly income (before taxes). Multiply by 100 to get the percentage. Use our calculator above for instant results.
DTI does not directly affect your credit score — credit bureaus don't track your income. However, high debt levels do affect your credit utilization ratio (30% of your score), and the high payments that come with high DTI make it harder to pay bills on time, which affects payment history (35% of your score).
Include all monthly debt payments: mortgage or rent, car loans, student loans, credit card minimum payments, personal loans, child support, and alimony. Do NOT include utility bills, groceries, insurance premiums, or other living expenses — these are not debts.
It's difficult but possible. FHA loans allow DTI up to 57% in some cases. However, lenders may require compensating factors like a high credit score (740+), large down payment (20%+), or significant cash reserves. A 50% DTI means half your income goes to debt — most financial experts recommend getting it below 43% before buying.
