The Debt-to-Income (DTI) ratio is one of the most important metrics in personal finance — and one of the least known. Lenders use it to assess whether you can afford new debt. You can use it to know when to borrow and when to hold back.
What Is DTI?
DTI is the percentage of your gross monthly income that goes toward debt repayments. Formula: DTI = (Total Monthly Debt Payments ÷ Gross Monthly Income) × 100. Debt payments include all EMIs (personal loans, car loans, home loans), credit card minimum payments, and any other recurring financial obligations.
DTI Thresholds
Most Indian lenders use the following benchmarks: Below 30% — low risk, strong eligibility for new credit. 30–40% — acceptable, most lenders will approve with standard terms. 40–50% — borderline, lenders may apply higher interest rates or require additional income proof. Above 50% — high risk, most mainstream lenders will decline. At this level, taking on additional debt is genuinely dangerous for your financial health.
Why This Matters More Than Your CIBIL Score Alone
A borrower with a CIBIL score of 780 and a DTI of 55% is, in practical terms, a higher risk than a borrower with a score of 720 and a DTI of 25%. Credit scores measure past behaviour; DTI measures current capacity. Both matter, but DTI is the better predictor of near-term default risk.
Improving Your DTI Before Applying
The two levers are: reduce debt payments (prepay high-EMI loans, close credit card balances) or increase income (variable pay, rental income, freelance income that can be documented). Most people focus only on the credit score before a loan application — a DTI check should happen at the same time. A 3–6 month DTI reduction plan before a large loan application can materially improve your terms.
