DHFL, IL&FS, Suzlon, Reliance Power, Jet Airways. Different sectors, same root cause — debt that the business couldn't service. The Debt-to-Equity (D/E) ratio is the single fastest red flag for balance-sheet stress. Master this one metric and you avoid 80% of value traps that look cheap on P/E but bleed to zero.
The formula
D/E = Total Debt / Shareholder Equity
Total Debt = short-term debt + long-term debt + current maturities of long-term debt. Shareholder Equity = paid-up capital + reserves & surplus. Both from the balance sheet.
Reading: D/E 0.5 means ₹0.50 of debt for every ₹1 of equity. D/E 2.0 means ₹2 of debt for every ₹1 of equity.
Sector-specific safe thresholds
| Sector | Safe D/E | Caution zone | Distress signal |
|---|---|---|---|
| IT services | < 0.1 | 0.1 - 0.3 | > 0.3 |
| FMCG / Consumer | < 0.3 | 0.3 - 0.6 | > 0.6 |
| Pharma | < 0.4 | 0.4 - 0.7 | > 0.7 |
| Auto / Manufacturing | < 0.6 | 0.6 - 1.0 | > 1.0 |
| Capital goods / Engineering | < 0.8 | 0.8 - 1.3 | > 1.3 |
| Real estate | < 0.7 | 0.7 - 1.5 | > 1.5 |
| NBFC | 3 - 5 (norm) | 5 - 7 | > 7 |
| Bank | 8 - 10 (norm) | 10 - 12 | > 12 or CRAR < 11 |
Banks and NBFCs have structurally high D/E because debt = customer deposits / borrowings used to lend. The right metric for them is CRAR (Capital Adequacy Ratio), not D/E. Anything below regulatory minimum (11% for banks, 15% for NBFCs) = distress.
Interest Coverage Ratio — the survival metric
D/E tells you how much debt. ICR tells you whether the company can pay the interest.
ICR = EBIT / Interest Expense
- ICR > 8: Strong. Plenty of room for earnings dips.
- ICR 5-8: Healthy. Standard for mid-cap businesses.
- ICR 3-5: Caution. One bad quarter and the company struggles to service debt.
- ICR 1-3: Distress zone. Most operating profit goes to lenders.
- ICR < 1: Bankruptcy risk. Operating profit insufficient to cover interest.
IL&FS had ICR of 1.4 in FY18 — should have flagged distress. Default came 6 months later.
The 4 red flags that signal stress
1. D/E rising YoY for 3+ years
Even healthy D/E (say 0.4) becomes a red flag if it's trending from 0.2 → 0.3 → 0.4 over 3 years. Means the business is funding growth via debt, not retained earnings — leverage spiral starting.
2. ICR declining while D/E rises
Worst combination. More debt, less ability to service it. Reliance Power 2015-2019 showed this pattern.
3. Short-term debt > 40% of total debt
Indicates the company is rolling over working capital with bank loans, not term debt. Refinancing risk if liquidity dries up (which happened to NBFCs in 2018 IL&FS crisis).
4. Promoter share pledge > 30%
Not directly D/E, but parallel signal. If promoters pledge their own shares for personal loans, they're leveraged at the personal level too. Force-sell of pledged shares during stock decline = death spiral.
BSE/NSE publishes promoter pledge disclosures quarterly. Many investors miss this. Above 30% pledge = serious caution. Above 60% = avoid regardless of other metrics.
D/E in DuPont — how leverage inflates ROE
Recall: ROE = Net Margin × Asset Turnover × Leverage. Leverage here = Assets / Equity = 1 + D/E.
A company with 8% net margin × 1.0× asset turnover × 3× leverage = 24% ROE. Looks elite. But that 3× leverage comes from D/E = 2 — distress zone for most sectors.
High ROE with high leverage isn't quality. It's engineered profit at higher risk. Use the DuPont breakdown to filter for businesses earning ROE via margin + asset turnover, NOT leverage.
The screening framework
- D/E ≤ sector safe threshold (see table above).
- ICR ≥ 5 for 3+ consecutive years.
- D/E trend stable or declining over 3-5 years.
- Short-term debt ≤ 40% of total debt.
- Promoter pledge < 15%.
Companies passing all 5 filters are the structurally sound ones. Combined with quality (ROE ≥ 15%) and reasonable valuation (P/E in line with sector), these are the long-term compounders worth holding through cycles.
Where to find the data
- screener.in: Balance Sheet → Borrowings, Reserves. Free, comprehensive.
- Company annual report: Notes to accounts → Borrowings schedule. Detailed maturity breakdown.
- BSE/NSE pledge disclosures: Filed quarterly. Search by company name.
- Tickertape: Quick visual D/E vs peer.
Don't trust headline financial-summary numbers alone. Always cross-check the balance sheet itself for the most recent quarter, not last-annual data which can be 6-12 months stale.
Use the DCF calculator with proper debt input to estimate intrinsic value with leverage-aware discount rates. Higher D/E = higher beta = higher WACC = lower intrinsic value.
