Return on Equity (ROE) measures how efficiently a company generates profit from shareholders’ equity—the money invested by owners plus retained earnings. An ROE of 20% means the company generates ₹20 profit for every ₹100 of shareholder capital. It’s one of the most important metrics for evaluating management efficiency and comparing companies across industries.
- Net income divided by shareholders’ equity
- Shows profit generated per rupee of shareholder capital
- Higher ROE indicates more efficient capital use
How ROE Works
The formula measures capital efficiency:
ROE = (Net Income ÷ Shareholders' Equity) × 100
Example:
Net Income: ₹150 crore
Shareholders' Equity: ₹600 crore
ROE = (150 ÷ 600) × 100 = 25%
Meaning:
Company generates ₹25 profit for every ₹100 of equity
Very efficient use of shareholder capital
Competitive businesses typically need 15%+ ROE
Quick Reference: ROE Interpretation
| ROE Range | Rating | Typical Industries |
|---|---|---|
| < 10% | Weak | Commodity, cyclical |
| 10-15% | Average | Manufacturing, utilities |
| 15-20% | Good | Most quality companies |
| 20-30% | Excellent | Consumer, pharma, IT |
| > 30% | Exceptional | Check for debt leverage |
Example: Comparing Company ROEs
IT Sector Comparison:
| Company | Net Income (₹Cr) | Equity (₹Cr) | ROE |
|---|---|---|---|
| TCS | 42,000 | 110,000 | 38% |
| Infosys | 24,000 | 78,000 | 31% |
| Wipro | 10,500 | 65,000 | 16% |
| Tech Mahindra | 5,500 | 42,000 | 13% |
Analysis:
- TCS has highest ROE—most efficient capital use
- Infosys close behind with 31%
- Wipro and Tech Mahindra lag significantly
- Higher ROE typically commands higher P/B ratio
ROE measures profit generated per rupee of shareholder equity. Calculate as net income divided by equity. Above 15% is good, above 20% is excellent. Compare within industries and check for consistency over multiple years.
DuPont Analysis: Breaking Down ROE
The DuPont formula decomposes ROE into three drivers:
ROE = Profit Margin × Asset Turnover × Equity Multiplier
Where:
Profit Margin = Net Income ÷ Revenue (profitability)
Asset Turnover = Revenue ÷ Total Assets (efficiency)
Equity Multiplier = Total Assets ÷ Equity (leverage)
Example:
ROE = 8% × 1.5 × 2.0 = 24%
This shows:
- 8% profit on every rupee of sales
- Assets generate 1.5x revenue
- 2x leverage (half equity, half debt)
Why ROE Matters
Stock Returns
Historically, high ROE companies deliver better long-term returns. Warren Buffett prioritizes consistent 15%+ ROE.
Management Quality
ROE reflects how well management deploys capital. Consistent high ROE signals competitive advantage.
P/B Justification
High P/B ratios are justified for high ROE companies. A company earning 30% ROE deserves to trade above book value.
Compounding Power
High ROE companies can reinvest profits at high rates, compounding value faster.
ROE Limitations
-
Debt distortion – High debt reduces equity, artificially boosting ROE. A company with ₹100 profit and ₹200 equity has 50% ROE; add ₹800 debt and equity drops but ROE spikes.
-
One-time items – Non-recurring gains or losses distort ROE. Use normalized earnings.
-
Negative equity – If equity is negative (losses > capital), ROE is meaningless.
-
Industry differences – Capital-intensive businesses naturally have lower ROE than asset-light businesses.
Common Mistakes
-
Ignoring leverage – Very high ROE from excessive debt is risky. Check debt-to-equity ratio.
-
One-year focus – Look at 5-year average ROE, not just latest year.
-
Comparing across industries – Banks have different ROE profiles than tech companies. Compare peers.
-
Ignoring sustainability – Check if high ROE comes from durable competitive advantage or temporary factors.
