ROE – Return on Equity
Return on Equity (ROE) measures how efficiently a company uses capital invested by shareholders to generate profit. It's one of the most watched profitability indicators.
How ROE is Calculated
Basic formula:
- Net Income is profit after taxes (bottom line from the Income Statement)
- Shareholders' Equity is the difference between assets and liabilities (found in the Balance Sheet)
For more accurate results, average equity is often used:
How to Interpret the Result
The value indicates how many dollars of profit the company earns for every 100 dollars of equity.
| ROE | Interpretation |
|---|---|
| < 5% | Low return, problematic |
| 5–10% | Below-average return |
| 10–15% | Average return |
| 15–20% | Above-average return |
| > 20% | High return (verify the cause) |
Example: A company has net income of $80 million and equity of $400 million. ROE is 20%. This means shareholders earned $20 for every $100 of invested capital.
Beware of Leverage Effect
ROE has an important limitation – it increases with rising leverage. A company may have high ROE simply because it has lots of debt and little equity.
Example of leverage effect:
| Company | Net Income | Equity | Debt | ROE |
|---|---|---|---|---|
| A | $100 mil. | $500 mil. | $0 | 20% |
| B | $100 mil. | $200 mil. | $300 mil. | 50% |
Company B has higher ROE, but it's due to Financial Leverage, not better efficiency.
Always combine ROE with leverage indicators like Debt-to-Equity.
DuPont Analysis – ROE Decomposition
For deeper understanding, ROE can be decomposed into three components:
This decomposition shows whether high ROE comes from:
- Profit margin – company has high margins
- Asset turnover – company efficiently uses assets (see Asset Turnover)
- Financial leverage – company uses a lot of debt
ROE vs. ROIC
| Indicator | What it Measures | Leverage Effect |
|---|---|---|
| ROE | Return for shareholders | Yes, increases ROE |
| ROIC | Efficiency of total capital | No |
For evaluating business quality, ROIC is often more reliable because it's not distorted by capital structure.
Industry Differences
Typical ROE values vary by industry:
- Technology – 15–30% (low capital requirements)
- Banks – 10–15% (regulatory capital requirements)
- Utilities – 8–12% (stable but regulated)
- Retail – 10–20% (depends on model)
When to Be Cautious
High ROE may be a warning signal if:
- High leverage – verify Debt-to-Equity ratio
- Declining equity – may be caused by losses or share buybacks
- One-time items – unusual gains distort results
- Negative equity – ROE doesn't make sense
How to Use the Indicator in Practice
For comprehensive profitability assessment, combine ROE with:
- ROIC – profitability without leverage effect
- ROA – return on total assets
- Debt-to-Equity – leverage level
Track the trend over time. Consistently high ROE (15–20%) with low leverage is a sign of quality company. High ROE with high debt requires caution.
Practical Tip
If a company has ROE above 20%, always check Debt-to-Equity. If D/E is above 2.0, high ROE is likely a result of financial leverage, not exceptional efficiency. Compare with ROIC for a more objective view.
