Return on Equity (ROE) is one of the most important profitability ratios in investing. It tells you how effectively a company uses the money shareholders have invested to generate profit.
The Formula
ROE = Net Income / Shareholders' Equity
If a company earns $50 million in net income and has $200 million in shareholders' equity, the ROE is 25%. That means the company generated $0.25 of profit for every $1 of equity.
What It Tells You
ROE measures management's ability to generate returns on the capital entrusted to them by shareholders. A higher ROE generally indicates a more efficient, well-managed company.
General benchmarks:
- Above 20%: Excellent
- 15% to 20%: Very good
- 10% to 15%: Good
- Below 10%: May be underperforming
But benchmarks vary significantly by industry. Utility companies often have ROE of 8-12%. Technology companies might have ROE of 25-40%.
Why It Matters
Compounding machine. A company with consistently high ROE is effectively compounding shareholder wealth. Warren Buffett has famously said he looks for companies with high, sustainable returns on equity.
Quality signal. Consistently high ROE over many years suggests a durable competitive advantage. If a company can earn 20%+ on equity year after year, it likely has something competitors cannot easily replicate.
Comparison tool. ROE lets you compare profitability across companies of different sizes. A $10 billion company and a $100 billion company might both have 18% ROE, telling you they are equally efficient at using equity.
Watch Out For
Debt inflates ROE. If a company takes on a lot of debt, equity decreases relative to total assets, which makes ROE look higher. Always check the debt-to-equity ratio alongside ROE.
One-time gains. A large asset sale or tax benefit can temporarily spike net income, making ROE look artificially high. Check whether the ROE is sustainable across multiple years.
Negative equity. If a company has negative shareholders' equity (liabilities exceed assets), ROE becomes meaningless or misleading.
How to Use It
Look for companies with:
- ROE consistently above 15% over 5+ years
- ROE that is stable or improving (not declining)
- ROE that is high relative to peers in the same industry
- ROE that is achieved without excessive leverage
