If Warren Buffett, Peter Lynch, and every quality investor on the planet agree on one metric, it's Return on Equity (ROE). Combined with Return on Capital Employed (ROCE), these two numbers tell you more about a business than any other ratio. This guide explains both, decomposes ROE via the DuPont framework, sets Indian sector benchmarks, and exposes the traps that make ROE misleading.
The formulas
ROE = Net Profit / Shareholder Equity. How efficiently the company converts shareholder money into profit.
ROCE = EBIT / (Total Equity + Total Debt − Current Liabilities). How efficiently the company uses all capital (equity + debt) to generate operating profit.
ROE looks at returns from the equity holder's view. ROCE looks at returns from the operating-business view, before financing decisions skew the picture.
The DuPont decomposition — where ROE comes from
ROE doesn't tell you HOW the company achieves its return. DuPont splits it into three drivers:
ROE = Net Margin × Asset Turnover × Leverage
Translation: profitability per rupee of sales × sales per rupee of assets × assets per rupee of equity.
| Business type | Net Margin | Asset Turnover | Leverage | Resulting ROE |
|---|---|---|---|---|
| FMCG (HUL) | ~15% | 1.5x | 1.5x | ~33% |
| IT services (TCS) | ~20% | 1.3x | 1.4x | ~36% |
| Cement (UltraTech) | ~12% | 0.6x | 2.0x | ~14% |
| Bank (HDFC) | ~25% | 0.08x | 9.0x | ~18% |
Two companies with same 18% ROE can be wildly different. A bank achieves 18% via massive leverage (9x). A cement company achieves 14% via moderate leverage and asset-heavy operations. The risk profiles are completely different — DuPont reveals this.
Indian sector ROE benchmarks (5-yr trailing average)
| Sector | Median ROE | Top quartile threshold | Bottom quartile flag |
|---|---|---|---|
| IT services | ~22% | > 28% | < 15% |
| FMCG | ~28% | > 50% (HUL/Nestle elite) | < 18% |
| Pharma | ~16% | > 22% | < 10% |
| Banks (private) | ~16% | > 18% | < 10% |
| NBFC | ~14% | > 20% | < 8% |
| Auto | ~14% | > 22% | < 8% |
| Cement | ~12% | > 18% | < 7% |
| Steel / Metals | ~10% | > 18% | < 5% |
| Power / Utilities | ~12% | > 16% | < 6% |
Rule: Filter for top quartile ROE within sector, not absolute number. A 14% ROE in cement is elite; the same 14% in IT services is mediocre.
The 5 traps that distort ROE
Trap 1: Buybacks artificially boost ROE
Companies that buy back shares reduce equity. With unchanged profit, ROE rises. This isn't operational improvement — it's financial engineering.
Fix: Look at ROCE alongside ROE. Buybacks don't affect ROCE significantly. If ROE jumped from 18% to 26% over 3 years but ROCE stayed flat, it's a buyback artifact.
Trap 2: One-time gains inflate ROE
Sale of a subsidiary, deferred tax credit reversal, or exceptional gain pumps net profit. ROE for that year looks spectacular and then falls back next year.
Fix: Use 3-year average ROE, not single-year. Read the “exceptional items” line in P&L.
Trap 3: Leverage inflates ROE
A heavily debt-funded company shows high ROE because equity is small. The same company would show modest ROCE because total capital employed is large.
Fix: Always check Debt-to-Equity alongside ROE. ROE > 25% with D/E > 2 = leveraged compounder. ROE > 25% with D/E < 0.3 = quality compounder.
Trap 4: Negative equity makes ROE meaningless
Companies with accumulated losses can have negative shareholder equity. ROE math breaks down (negative denominator). Stay away from these regardless of headline number.
Trap 5: Asset-light models inflate ROE for IT/services
Software services companies need minimal physical assets. ROE shoots above 30% naturally. Doesn't mean the business is “better” than capital-intensive sectors — just different.
Fix: Use sector-relative ranking, not absolute. Compare TCS ROE against Infosys ROE (both IT), not against UltraTech ROE (cement).
The compounding magic of high ROE
A business compounding at sustained 20% ROE doubles intrinsic value every 3.6 years. At 25% ROE, every 2.9 years. At 15%, every 4.8 years.
Compounded over 20 years:
- 20% ROE business: ~38x book value growth
- 25% ROE business: ~86x book value growth
- 15% ROE business: ~16x book value growth
This is why quality investors obsess over the 25%+ club. Asian Paints, HDFC Bank, Nestle India, Pidilite, Bajaj Finance all spent 15+ years above 20% ROE — and delivered 20-30x returns to shareholders in that window.
The screening framework
For quality-tilt long-term investing:
- ROE ≥ 15% for 5+ consecutive years. Consistency, not single-year spike.
- ROCE ≥ 15% for 5+ consecutive years. Operating efficiency, not financing tricks.
- ROCE within 4 percentage points of ROE. If ROCE is 12% but ROE is 25%, leverage is doing the heavy lifting — red flag.
- Top quartile within sector. Sector-relative, not absolute.
- ROE trend = stable or rising. Falling ROE = pricing power deteriorating or competition eating margins.
Stocks passing all five filters are the small universe of quality compounders. Combined with reasonable P/E (use the P/E Fair Value calculator) and low debt, this is the framework behind most successful long-term Indian investing programmes.
