What Is Return on Equity
Return on equity, commonly known as ROE, is one of the most important profitability ratios used to evaluate how well a company uses the money that shareholders have invested. At its core, ROE answers a simple question: for every dollar of equity in the business, how many cents of profit did the company generate? It is a direct measure of management's ability to create value from the capital trust by shareholders.
ROE is calculated by dividing net income by shareholders' equity and multiplying by 100 to express the result as a percentage. If a company earns $200,000 in net income and has $1,000,000 in average shareholders' equity, the ROE is 20%. This means the company generated 20 cents of profit for every dollar of equity. A higher ROE generally indicates more efficient management of equity capital.
ROE is particularly valuable because it measures the return on the capital that belongs to the owners — not the return on total assets (which includes debt-financed assets). This makes it a key metric for investors deciding whether a company is a good use of their capital. Warren Buffett, for example, has long favored companies that consistently achieve high ROE without excessive leverage.
However, ROE is not without limitations. A company can inflate its ROE by taking on more debt (which reduces equity), by buying back shares (which also reduces equity), or by retaining very little earnings. The DuPont analysis method decomposes ROE into three drivers — profit margin, asset turnover, and financial leverage — to reveal whether the high ROE is coming from operational excellence or financial risk. Always analyze ROE alongside other metrics and within industry context.
How to Use This Calculator
Enter your company's net income and shareholders' equity (either average equity or ending equity, depending on your preference). The calculator will instantly compute your return on equity as a percentage.
Entering Net Income
Use the net income figure from the income statement after all expenses, taxes, and preferred dividends have been deducted. If you are calculating ROE for common shareholders specifically, subtract preferred dividends from net income. For the most accurate annual ROE, use the full-year net income figure.
Entering Shareholders Equity
Shareholders' equity is found on the balance sheet. For the most accurate result, use average equity (beginning equity + ending equity divided by 2) because net income is earned over a period while equity is a point-in-time figure. If beginning equity is not available, ending equity is acceptable for a quick estimate.
Reading the Results
The calculator shows your ROE as a percentage. A result above 15% is generally considered good for established companies. Above 20% is excellent. Below 10% may indicate room for improvement, though capital-intensive industries often have lower ROEs by nature. Compare your result to your industry average and your company's historical performance.
Formula
Return on equity: ROE = Net Income / Average Shareholders' Equity × 100
DuPont decomposition: ROE = Profit Margin × Asset Turnover × Equity Multiplier
Profit margin: PM = Net Income / Revenue
Asset turnover: AT = Revenue / Total Assets
Equity multiplier: EM = Total Assets / Shareholders' Equity
Examples
Example 1: Profitable Consumer Goods Company
A consumer goods company reports net income of $500,000 and average shareholders' equity of $2,500,000. ROE = $500,000 / $2,500,000 × 100 = 20%. This is an excellent ROE, indicating the company generates 20 cents of profit for every dollar of equity. If the industry average is 15%, this company is outperforming peers and creating superior value for shareholders.
Example 2: Leveraged Company
A retail company has net income of $300,000 and average equity of $600,000 (low because of heavy debt financing). ROE = $300,000 / $600,000 × 100 = 50%. This looks spectacular, but the company has $4,000,000 in total liabilities against $600,000 in equity — a D/E ratio of 6.7. The high ROE is driven by leverage, not operational efficiency. The company is vulnerable to interest rate increases and revenue declines.
Example 3: Declining ROE Trend
A manufacturing company had ROE of 22% three years ago, 16% two years ago, and 11% last year. Net income has fallen from $440,000 to $320,000 to $220,000 while equity has remained around $2,000,000. The declining trend signals eroding profitability — perhaps due to rising costs, increased competition, or pricing pressure. An investor seeing this trend would investigate the root causes before making an investment decision.
Tips
Use the DuPont Analysis
A high ROE can come from three sources: high profit margins, high asset turnover, or high financial leverage. The DuPont analysis decomposes ROE into these three components, revealing whether the return is driven by pricing power (margin), operational efficiency (turnover), or debt (leverage). A company with high ROE from margins and turnover is fundamentally different from one relying on leverage.
Track ROE Over Multiple Years
A single year of high ROE is not enough. Look for consistency over at least five years. Companies that sustain high ROE have durable competitive advantages — strong brands, pricing power, network effects, or cost advantages. One-time spikes in ROE from asset sales or unusual items are not sustainable.
Compare to Industry Peers
Different industries have structurally different ROE levels. Utility companies typically earn 8–12% ROE due to regulated returns on large asset bases. Technology companies can earn 25%+ ROE because they require fewer tangible assets. Always compare your ROE to companies in the same industry and of similar size.
Watch for Share Buyback Effects
When a company buys back its own shares, equity decreases. If net income stays the same, ROE increases mechanically — not because the company is more profitable, but because the equity base shrank. This is not necessarily bad, but it can make ROE comparisons misleading if one company has been aggressively buying back shares while another has not.
FAQ
What is return on equity (ROE)?
Return on equity (ROE) measures how effectively a company uses shareholders' equity to generate profit. It is calculated by dividing net income by average shareholders' equity and expressing the result as a percentage. ROE tells investors and management how many cents of profit are generated for each dollar of equity invested. A higher ROE indicates more efficient use of equity capital.
What is a good ROE?
A good ROE varies by industry, but a general benchmark is 15% or higher for established companies. Many top-performing companies sustain ROE above 20% consistently. Below 10% may indicate inefficiency, though context matters — a utility with stable cash flows might have a lower but acceptable ROE compared to a tech company. Always compare ROE to industry peers and the company's own historical trend.
Can ROE be too high?
Yes. An extremely high ROE can be misleading. If a company has very low equity (due to accumulated losses, large dividends, or aggressive share buybacks), even modest net income produces a very high ROE. This is not a sign of efficiency — it is a sign of a depleted equity base. Always check the equity composition and the company's debt level when interpreting a high ROE.
How does debt affect ROE?
Debt can increase ROE through financial leverage. When a company borrows money at a lower interest rate than its return on assets, the excess return flows to shareholders, boosting ROE. However, this increases risk — the company must service the debt regardless of performance. A company with a high ROE driven by heavy debt is riskier than one with a high ROE driven by operational efficiency.
What is the DuPont analysis of ROE?
The DuPont analysis decomposes ROE into three components: profit margin (net income / revenue), asset turnover (revenue / total assets), and equity multiplier (total assets / equity). ROE = Profit Margin × Asset Turnover × Equity Multiplier. This breakdown reveals whether a high ROE is driven by profitability, operational efficiency, or financial leverage — each with different risk implications.
Should I use average equity or ending equity?
Using average equity (beginning equity + ending equity divided by 2) is more accurate because net income is earned over a period while equity is measured at a point in time. Using ending equity can distort ROE if equity changed significantly during the period (e.g., due to a large share issuance or buyback). For annual calculations, average equity is the standard approach.
How does ROE differ from ROA?
ROE measures profit relative to shareholders' equity, while ROA measures profit relative to total assets. The difference matters because assets can be financed by both equity and debt. A company with high debt will have a higher ROE than ROA because the equity base is smaller. ROA gives a broader view of how well all resources are used, while ROE focuses specifically on returns to shareholders.
How often should I calculate ROE?
Most analysts calculate ROE quarterly and annually, aligned with financial reporting. For internal management purposes, monthly tracking can provide earlier warnings of declining profitability. When comparing companies, use the same time period and the same calculation method (average equity vs. ending equity) to ensure a fair comparison.
