What Is Return on Equity (ROE)?
Return on Equity measures how efficiently a company generates profits from shareholders' investment. It's one of the most important metrics for evaluating management effectiveness.

1. The ROE Formula
Formula
Net Income is the company's profit after all expenses, taxes, and interest. Find it at the bottom of the income statement (often called "bottom line").
Shareholders' Equity is what remains after subtracting total liabilities from total assets. It represents the book value of the company owned by shareholders.
ROE is expressed as a percentage. A 20% ROE means the company generates $0.20 of profit for every $1.00 of shareholders' equity.
2. Calculation Example
Let's calculate Apple's ROE using FY2024 data:
- Net Income: $93.7 billion
- Shareholders' Equity: $57.0 billion
- ROE: $93.7B / $57.0B = 164%
Apple's ROE is exceptionally high because the company has been aggressively buying back shares, reducing equity while maintaining strong profits. This shows why ROE alone doesn't tell the whole story.
3. What Is a Good ROE?
| ROE Range | Interpretation |
|---|---|
| <10% | Below average, may struggle to grow |
| 10-15% | Average, acceptable for stable industries |
| 15-20% | Good, indicates efficient management |
| >20% | Excellent, strong competitive advantage |
| >50% | Investigate further (may be due to high debt or low equity) |
Warren Buffett looks for companies with ROE consistently above 15%. However, always compare ROE within the same industry, as capital requirements vary significantly by sector.
4. ROE by Sector
Typical ROE ranges vary by industry:
| Sector | Typical ROE | Why |
|---|---|---|
| Technology | 15-30% | Low capital needs, high margins |
| Consumer Staples | 15-25% | Strong brands, pricing power |
| Healthcare | 10-20% | R&D intensive, variable by sub-sector |
| Financials | 10-15% | Regulated, capital requirements |
| Utilities | 8-12% | Capital intensive, regulated returns |
| REITs | 5-10% | Required dividend payouts reduce equity |
5. ROE Limitations
High Debt Distortion
Companies with high debt have lower equity, artificially inflating ROE. A company with 80% debt-to-equity might show 30% ROE but be riskier than a competitor with 20% debt and 15% ROE.
Negative Equity
Some profitable companies like McDonald's and Boeing have negative equity due to share buybacks. ROE becomes meaningless (or misleading) in these cases.
One-Time Items
Large one-time gains or losses can temporarily spike or crash ROE. Always look at 5+ year trends, not single-year numbers.
6. DuPont Analysis
Break down ROE into three components to understand why ROE is high or low:
ROE = Profit Margin x Asset Turnover x Financial Leverage
- Profit Margin = Net Income / Revenue (how much profit per dollar of sales)
- Asset Turnover = Revenue / Assets (how efficiently assets generate sales)
- Financial Leverage = Assets / Equity (how much debt is used)
Two companies with 20% ROE might get there differently: one through high margins (Apple), another through high turnover (Walmart), and another through leverage (banks). Understanding the source helps assess sustainability.
