ROE (Return on Equity) is a key profitability metric that measures how efficiently a company generates profit from shareholders’ equity. It tells you how much net income a company earns for every rupee of equity capital invested by shareholders. ROE is one of the most important ratios in fundamental analysis and a favorite metric of legendary investors like Warren Buffett for identifying high-quality businesses.
ROE Formula and Calculation
The formula is: ROE = Net Income ÷ Shareholders’ Equity × 100. Net income is the company’s profit after all expenses, taxes, and interest. Shareholders’ equity is total assets minus total liabilities — it represents what shareholders actually own in the company. Both figures are available on the company’s annual financial statements.
For example, if Infosys has net income of ₹22,000 crore and shareholders’ equity of ₹80,000 crore, the ROE is (22,000 ÷ 80,000) × 100 = 27.5%. This means for every ₹100 of equity, Infosys generates ₹27.50 in profit — an excellent return indicating a highly efficient, profitable business.
What Is a Good ROE?
In the Indian market context, an ROE above 15% is generally considered good, above 20% is excellent, and above 25% indicates an exceptional business. For reference, top Indian companies show these typical ROE ranges: IT services (TCS, Infosys) deliver 25-35% ROE, FMCG companies (HUL, Nestle) deliver 20-40% ROE, banks (HDFC Bank, Kotak) deliver 14-18% ROE, and capital-intensive sectors (steel, power) typically show 8-15% ROE.
Always compare ROE within the same industry. Banking ROE of 15% is excellent, but the same figure for an IT company would be below average. The key insight is that consistently high ROE over 5-10 years indicates a durable competitive advantage — the company has something special that allows it to earn exceptional returns on capital.
DuPont Analysis: Breaking Down ROE
The DuPont framework breaks ROE into three components to understand what drives it: ROE = Net Profit Margin × Asset Turnover × Equity Multiplier. Net Profit Margin measures how much profit the company keeps from each rupee of revenue. Asset Turnover measures how efficiently the company uses its assets to generate revenue. Equity Multiplier measures how much leverage (debt) the company uses.
This decomposition reveals important differences. Two companies might both have 20% ROE, but one achieves it through high margins (like TCS with 25%+ margins) while the other achieves it through high leverage (high debt-to-equity ratio). The first is sustainable quality; the second carries financial risk. Always investigate the source of high ROE, not just the headline number.
ROE vs Other Profitability Metrics
ROE vs ROA (Return on Assets): ROA measures return on total assets regardless of how they are funded. ROE measures return specifically on equity. When ROE is much higher than ROA, it means the company is using significant debt leverage. A healthy business should show both strong ROE and reasonable ROA.
ROE vs ROCE (Return on Capital Employed): ROCE considers both equity and debt capital, making it a more comprehensive measure for companies with significant debt. For debt-free companies, ROE and ROCE will be similar. For leveraged companies, always check ROCE alongside ROE to get the full picture.
ROE vs EPS: EPS shows profit per share in absolute terms while ROE shows return as a percentage of equity. A company can grow EPS by raising equity capital (issuing new shares), but if ROE declines in the process, shareholders are actually getting a worse deal despite higher absolute profits.
How to Use ROE for Stock Selection
Look for companies with ROE consistently above 15% for at least 5 years — consistency matters more than a single high year. Compare the company’s ROE to its industry average and to its own historical trend. Rising ROE suggests improving business quality; declining ROE despite growing revenues is a red flag. Pair ROE analysis with Price-to-Book ratio to identify quality companies available at reasonable valuations.
Frequently Asked Questions
Can ROE be negative?
Yes, ROE becomes negative when a company reports a net loss. A negative ROE means the company is destroying shareholder value — spending more than it earns. Occasional negative ROE during a cyclical downturn (like in commodities) may be acceptable, but consistently negative ROE indicates a fundamentally troubled business. Avoid investing in companies with negative ROE for more than 2 consecutive years unless you have a specific turnaround thesis.
Why do some companies have very high ROE above 50%?
Extremely high ROE can result from two very different situations. First, genuinely exceptional businesses with minimal capital needs — companies like ITC, HUL, or some IT firms earn massive profits relative to their small equity base because their business models don’t require heavy assets. Second, companies with very high debt — the equity multiplier inflates ROE even if the underlying business is mediocre. Use debt-to-equity ratio to distinguish between the two.
Is ROE useful for evaluating banks?
Yes, ROE is one of the most important metrics for bank analysis. Banks are leveraged businesses by nature, so the equity multiplier component is always high. For Indian banks, an ROE of 14-18% is considered very good (HDFC Bank has historically maintained 16-17% ROE). ROE below 10% for a bank suggests poor asset quality or weak profitability. Always look at ROE alongside NPAs (Non-Performing Assets) for a complete banking analysis.
