How to Calculate Your Debt-to-Income Ratio
DTI = Total Monthly Debt Payments ÷ Gross Monthly Income × 100. Include: mortgage or rent, car payments, student loan payments, minimum credit card payments, and any other installment debt. Do not include utilities, insurance, groceries, or other living expenses. Gross income is before taxes — not take-home pay.
Sample DTI calculation
| Monthly Debt Payment | Amount |
|---|---|
| Rent / Mortgage | $1,500 |
| Car Payment | $350 |
| Student Loan | $280 |
| Credit Card Minimums | $120 |
| Other Loan | $0 |
| Total Monthly Debt | $2,250 |
| Gross Monthly Income | $6,500 |
| DTI | 34.6% |
Under 36% DTI: typically approved at competitive rates. 36-43% DTI: approved at most lenders with restrictions. 43-50% DTI: limited lender options; higher rates likely. Above 50% DTI: approval very difficult; address debt before borrowing.
How to Improve Your DTI Before Applying
- Pay off small debts entirely — eliminating a $150/month car payment reduces DTI by $150 (a significant improvement)
- Increase income: a side job, part-time work, or documented raise can move DTI into the approval zone
- Pay down credit card balances — this reduces the minimum monthly payment requirement
- Do not take on new debt in the 2-3 months before applying for a personal loan
- Consider a co-borrower with income — their income is added to yours in DTI calculation
- Ask about lender exceptions: some lenders make DTI exceptions for high credit scores or strong assets
Front-End vs. Back-End DTI
Mortgage lenders use two DTI figures: front-end (housing costs only as % of income) and back-end (all debt as % of income). Personal loan lenders typically use only the back-end DTI. Keeping your back-end DTI below 36% before applying for a personal loan is the cleanest path to approval and competitive rates.
