Check Your Debt-to-Income Ratio
Calculate your front-end and back-end DTI to understand your loan eligibility before applying with lenders.
Calculate My DTI NowKey Takeaways
- DTI under 36%: Excellent chance of loan approval
- 43% rule: Maximum for Qualified Mortgages
- Two types: Front-end (housing only) and back-end (all debts)
- Not on credit report: DTI doesn't affect your credit score
- Lower is better: Reduce debt or increase income to improve DTI
When you apply for a mortgage, personal loan, or auto loan, lenders look at two main numbers: your credit score and your Debt-to-Income (DTI) Ratio. Your DTI tells lenders how much of your monthly income is already eaten up by debts. If it's too high, you'll be rejected, even with perfect credit. Our free DTI calculator helps you check where you stand before you apply.
What Is DTI Ratio?
Your DTI is the percentage of your gross monthly income that goes toward paying debts. It is the primary way lenders measure your ability to repay a new loan.
What Counts as "Debt"?
- Rent or Mortgage payments
- Car loans
- Student loans
- Credit card minimum payments
- Personal loans
- Alimony or child support
What Does NOT Count?
Living expenses usually don't count toward DTI, such as:
- Groceries, utilities, gas
- Cell phone bills
- Entertainment/streaming services
Front-End vs. Back-End DTI
Mortgage lenders specifically look at two types of DTI:
1. Front-End Ratio (Housing Ratio)
The percentage of income that goes toward housing costs only (Mortgage principal, interest, taxes, insurance, HOA). Lenders typically want this below 28%.
2. Back-End Ratio (Total Debt)
The percentage of income that goes toward all debts (Housing + Cars + Credit Cards + Student Loans + Personal Loans). Lenders typically want this below 36%, though some loans allow up to 43% or even 50%.
How to Calculate Your DTI
Follow these steps to calculate your debt-to-income ratio:
- Add up monthly debts: Include rent/mortgage, car payments, minimum credit card payments, student loans, personal loans, alimony/child support
- Find gross monthly income: Your income before taxes and deductions
- Divide and multiply: Debts divided by income x 100 = DTI %
- Calculate both ratios: Front-end (housing costs only) and back-end (all debts)
- Compare to guidelines: Check your DTI against lender requirements
Example Calculation
Gross Monthly Income: $5,000
Debts:
- Rent: $1,200
- Car Loan: $400
- Student Loan: $200
- Credit Cards: $100
Total Debt: $1,900
DTI Calculation: ($1,900 / $5,000) x 100 = 38%
Result: This is slightly above 36% ideal, but under 43% limit.
The 43% Rule and DTI Ranges
According to CFPB, 43% is generally the maximum DTI ratio you can have and still get a "Qualified Mortgage." A Qualified Mortgage is a loan that meets certain standards for borrower protection.
| DTI Range | Rating | What It Means |
|---|---|---|
| Below 20% | Excellent | Great financial health, lenders love you |
| 20% - 36% | Good | Most lenders approve easily |
| 37% - 43% | Acceptable | May need compensating factors |
| 44% - 50% | High Risk | Difficult to get approved, higher rates |
| Above 50% | Dangerous | Financial distress, rarely approved |
How to Lower Your DTI
If your ratio is too high, you have two options:
- Increase Income: Pick up a side hustle, ask for a raise, or include a co-borrower's income.
- Decrease Debt: This is usually easier. Pay off small balances to eliminate monthly payments completely. For example, paying off a credit card eliminates its minimum payment from calculation.
Hidden Factor: Residual Income
For VA Loans, lenders care more about Residual Income (money left over for food/gas) than just DTI. A high DTI might be ignored if you have strong residual cash flow.
The "Self-Employed" Tax Trap
Self-employed? Lenders look at your Net Income (after expenses) on tax returns, not your gross revenue.
If you write off everything to save on taxes, you might accidentally disqualify yourself from a mortgage because your "paper income" looks too low.
Pro Strategy: Compensating Factors
DTI above 43%? You might still get approved if you have "Compensating Factors":
- Cash Reserves: 6+ months of mortgage payments in savings.
- Low Credit utilization: Using less than 10% of credit limits.
- Long Job History: 5+ years at the same employer.
Mortgage DTI Requirements
Different loan types have different DTI requirements:
| Loan Type | Typical DTI Limit | Requirements |
|---|---|---|
| Conventional Mortgage | 43% | Minimum 620 credit score, 20% down payment, 2 years employment history |
| FHA Loan | 50% | Minimum 580 credit score, 3.5% down payment, 2 years employment history |
| VA Loan | 41% | Military service or surviving spouse, no minimum credit score required |
| USDA Loan | 41% | Rural location, income limits apply, no minimum credit score |
| Personal Loan | 40-50% | Good to excellent credit preferred, steady income required |
| Auto Loan | 35-45% | Vehicle age and mileage requirements, stable employment preferred |
Common Mistakes to Avoid
- Forgetting to include all debts: Be sure to include every recurring monthly obligation in your calculation
- Using net income instead of gross: DTI is calculated on pre-tax income, not take-home pay
- Applying for new credit before a mortgage: New accounts increase DTI and create hard inquiries
- Miscounting minimum credit card payments: Use the minimum required payment shown on your statement, not your usual payment
- Ignoring upcoming debt changes: If a 0% promotional period ends soon, factor in the new payment
- Forgetting co-signed loans: If you co-signed someone else's loan, that payment counts toward your DTI
Improving Credit for Better DTI
Since DTI doesn't affect credit score directly, improving your credit can help you qualify for better loan rates:
- Pay all bills on time: Payment history is 35% of your credit score
- Keep credit utilization low: Use less than 30% of available credit
- Don't apply for too many loans: Multiple applications create hard inquiries that lower score
- Review credit reports annually: Correct errors that may be hurting your score
- Maintain older accounts: Length of credit history improves your score
- Limit new credit applications: Space applications by at least 14-30 days

DTI Requirements Around the World
Debt-to-income ratio standards and lending regulations vary significantly across countries. Here is how lenders in major markets assess borrower capacity:
