Return on Equity (ROE) is a profitability ratio that measures how much net income a company generates for each dollar of shareholder equity. Calculated as net income divided by shareholder equity, ROE shows how efficiently a company uses investor capital to produce profits. An ROE of 15% means the company generated $0.15 in profit for every dollar of equity—a key metric for evaluating management effectiveness and comparing companies within the same industry.
Key Takeaways
- ROE measures net income relative to shareholder equity, typically expressed as a percentage showing profit generation efficiency
- The formula is straightforward: Net Income ÷ Shareholder Equity × 100, using data from income statements and balance sheets
- An ROE above 15-20% is generally considered strong for most industries, though sector norms vary significantly
- High ROE can signal efficiency or excessive debt leverage—context matters when interpreting this metric
- Compare ROE against industry peers and historical company trends rather than using absolute thresholds

What Is Return on Equity (ROE)?
Return on Equity (ROE) measures how effectively a company converts shareholder equity into net income. This profitability ratio tells you how many dollars of profit a company generates for each dollar that shareholders have invested. When you see an ROE of 18%, that means the company produced $0.18 in net income for every dollar of equity on its balance sheet.
Return on Equity (ROE): A financial ratio that divides net income by shareholder equity to measure profitability relative to the equity base. It indicates how efficiently management deploys shareholder capital to generate earnings.
ROE sits alongside other profitability ratios like Return on Assets (ROA) and Return on Invested Capital (ROIC) as a core metric for evaluating company financials. Unlike revenue or earnings growth, which show absolute expansion, ROE reveals efficiency—whether a company needs $1 billion or $10 billion in equity to generate the same profit level.
Investors use ROE to compare companies within the same sector and to track whether management is improving or deteriorating in capital efficiency over time. A rising ROE trend often signals strengthening competitive position, while declining ROE may indicate margin pressure or inefficient capital allocation.
How Do You Calculate ROE?
The basic ROE formula divides net income by shareholder equity, then multiplies by 100 to express the result as a percentage. Both numbers come from standard financial statements—net income from the income statement and shareholder equity from the balance sheet.
ROE Formula:
ROE = (Net Income ÷ Shareholder Equity) × 100
Here's a concrete example using real numbers. Suppose Company X reports net income of $500 million for the fiscal year and has shareholder equity of $2.5 billion on its balance sheet:
ROE = ($500 million ÷ $2,500 million) × 100 = 20%
This 20% ROE means Company X generated $0.20 in profit for every dollar of equity. When calculating ROE yourself, use the equity figure from the same period-end as the income statement. Some analysts prefer average equity (beginning equity plus ending equity divided by two) to smooth out fluctuations from equity changes during the year.
Shareholder Equity: The residual value belonging to shareholders after subtracting total liabilities from total assets. Also called stockholders' equity or book value, this represents the net worth attributable to owners.
You can pull these figures from SEC filings for public companies—net income appears on the income statement (often labeled "Net Income Attributable to Common Shareholders"), while shareholder equity sits in the equity section of the balance sheet. Tools like the AI Research Assistant can extract these values instantly from financial statements when you're researching specific stocks.
What Is a Good ROE Percentage?
An ROE above 15% is often considered solid for most industries, though "good" varies significantly by sector. Technology and consumer goods companies frequently post ROE figures of 20-30% or higher, while capital-intensive industries like utilities or manufacturing typically run closer to 8-12%.
Industry Sector Typical ROE Range Key Characteristics Technology 18-35% High margins, low capital requirements Consumer Goods 20-30% Brand power, efficient operations Financials (Banks) 10-15% Regulated leverage, cyclical earnings Utilities 8-12% Capital-intensive, regulated returns Retail 15-25% Varies widely by business model Energy 5-15% Commodity-driven, cyclical
Context matters more than absolute thresholds. Compare a company's current ROE to three benchmarks: its own 5-year average (is it improving or declining?), direct competitors in the same industry (who's most efficient?), and the broader sector average (is this company above or below par?).
An ROE above 20% sustained over multiple years suggests either genuine competitive advantages—strong brands, network effects, operational excellence—or financial engineering through debt leverage. That distinction makes all the difference, which is why you shouldn't evaluate ROE in isolation.
Why ROE Matters to Investors
ROE tells you whether management is putting your capital to work effectively. When you buy stock, you're effectively handing money to company executives and trusting them to deploy it better than you could yourself. ROE quantifies how well they're executing on that responsibility.
Companies with consistently high ROE can compound shareholder value faster because they generate more earnings from the same equity base. If a company earns a 25% ROE and retains all profits, shareholder equity grows by 25% that year, setting up potentially higher earnings next year. This compounding effect explains why investors often pay premium valuations for high-ROE businesses.
Warren Buffett has famously highlighted ROE as a critical metric, particularly favoring companies that maintain above-average ROE with minimal debt. Berkshire Hathaway's annual letters frequently analyze portfolio companies through the lens of return on equity, emphasizing sustained performance over time rather than single-year spikes.
Advantages of Using ROE
- Simple calculation using widely available financial data
- Directly measures management effectiveness at deploying capital
- Enables quick comparison across companies and time periods
- Highlights compounding potential for reinvested earnings
Limitations of ROE
- Can be artificially inflated by high debt levels
- Doesn't work for companies with negative equity
- Varies significantly across industries
- Can mislead when equity base shrinks from buybacks or losses
Understanding ROE Through DuPont Analysis
The DuPont formula breaks ROE into three components to reveal what's actually driving returns. This decomposition, developed by the DuPont Corporation in the 1920s, helps you understand whether high ROE comes from operational excellence, asset efficiency, or financial leverage.
DuPont Formula:
ROE = (Net Profit Margin) × (Asset Turnover) × (Equity Multiplier)
Or expressed in accounting terms:
ROE = (Net Income ÷ Revenue) × (Revenue ÷ Assets) × (Assets ÷ Equity)
DuPont Analysis: A framework that decomposes return on equity into profit margin, asset turnover, and financial leverage components. It helps identify the specific drivers behind ROE performance.
Each component tells a different story. Net profit margin measures operational efficiency—how much of each revenue dollar reaches the bottom line. Asset turnover indicates how efficiently the company uses its asset base to generate sales. The equity multiplier reflects financial leverage—how much assets the company controls relative to its equity base.
Consider two companies, both with 20% ROE:
Company A: 10% margin × 2.0 asset turnover × 1.0 equity multiplier = 20% ROE
Company B: 5% margin × 1.0 asset turnover × 4.0 equity multiplier = 20% ROE
Company A achieves its ROE through strong margins and efficient asset use with no debt. Company B reaches the same ROE through heavy leverage (equity multiplier of 4.0 means debt-to-equity is roughly 3:1). Company A's ROE is more sustainable and less risky, even though the headline numbers match.
You can explore these underlying metrics more deeply in our complete guide to financial ratios explained, which covers margin analysis, efficiency ratios, and leverage metrics in detail.
Limitations and Context for ROE
ROE has blind spots that can mislead if you don't account for them. The metric breaks down or produces misleading signals in several common scenarios worth understanding before you rely on it for investment decisions.
Leverage Distortion: Companies can boost ROE simply by taking on more debt, which reduces the equity denominator without necessarily improving operations. A company that borrows heavily to buy back shares will show rising ROE even if actual business performance stays flat. This is why you should always examine ROE alongside debt ratios and interest coverage.
Negative Equity Problems: Companies with negative shareholder equity (liabilities exceed assets) produce negative or nonsensical ROE figures. This often happens after years of losses or massive share buybacks that exceed retained earnings. When equity approaches zero, ROE becomes mathematically extreme and loses practical meaning.
Share Buyback Effects: Aggressive buyback programs reduce shareholder equity, which mechanically inflates ROE even if earnings remain constant. A company repurchasing 10% of shares outstanding will see ROE rise roughly 11% (all else equal) without any operational improvement. Some investors view this as legitimate value creation; others see it as financial engineering.
Industry Context: Comparing ROE across different sectors is like comparing fish to bicycles. Capital-intensive businesses (utilities, railroads, manufacturers) naturally run lower ROE than asset-light businesses (software, consulting, brands). A utility with 9% ROE might be exceptional; a software company with the same figure might be struggling.
Cyclical Variation: ROE fluctuates with business cycles, particularly in commodity-linked or economically sensitive industries. Energy companies might show 25% ROE at peak cycle and 5% ROE in downturns. Looking at 5-7 year averages smooths out these swings and reveals more about sustainable earning power.
Red Flags When Analyzing ROE
- ☐ ROE rising while profit margins are declining (leverage-driven)
- ☐ ROE significantly above industry peers without clear competitive advantage
- ☐ Volatile ROE swinging widely year-to-year (cyclical or operational instability)
- ☐ High ROE paired with high debt-to-equity ratios above 2.0
- ☐ Shrinking equity base from buybacks masking flat or declining earnings
How ROE Compares to Other Profitability Ratios
ROE works best alongside other profitability ratios that measure different aspects of company performance. Each metric answers a slightly different question about how efficiently the company generates returns.
Metric Formula What It Measures When to Use It ROE Net Income ÷ Equity Returns to shareholders specifically Comparing equity efficiency, evaluating management ROA Net Income ÷ Total Assets Returns on all assets regardless of funding Comparing asset-heavy businesses, isolating operations from capital structure ROIC NOPAT ÷ Invested Capital Returns on all invested capital (debt + equity) Evaluating total capital efficiency, comparing across capital structures Net Margin Net Income ÷ Revenue Profit efficiency per dollar of sales Assessing pricing power and cost control Return on Assets (ROA): Net income divided by total assets, measuring how efficiently a company uses all its assets to generate profit regardless of how those assets are financed. Lower than ROE for levered companies.
ROA strips out capital structure effects by measuring returns against all assets rather than just equity. This makes it better for comparing companies with different debt levels. A company with 15% ROE and 8% ROA is using leverage to boost equity returns; one with 15% ROE and 14% ROA is achieving returns primarily through operations.
Return on Invested Capital (ROIC) measures returns on all capital invested in the business—both debt and equity. Many professional investors prefer ROIC to ROE because it focuses on how well the company deploys all available capital rather than just the equity slice. ROIC above the company's cost of capital indicates value creation.

Using ROE in Stock Analysis
Incorporating ROE into your research process requires looking at trends, peer comparisons, and supporting metrics rather than treating any single number as definitive. Here's how to actually use this ratio when evaluating potential investments.
Step 1: Establish the Trend
Pull 5-7 years of ROE data to see the trajectory. Consistently rising ROE suggests improving efficiency or competitive position. Declining ROE might signal margin pressure, capital misallocation, or intensifying competition. Flat ROE indicates steady-state operations—not necessarily bad if the absolute level is strong.
Step 2: Compare to Industry Peers
Identify 3-5 direct competitors and compare their ROE figures. Who's most efficient? Who's declining? If your target company shows ROE significantly above peers, dig into why—is it operational superiority, accounting differences, or leverage? Natural language stock screeners like the Vibe Screener let you filter for companies with ROE above specific thresholds within sectors.
Step 3: Check the Components
Run a quick DuPont breakdown to understand what's driving ROE. Look at net profit margin trends (expanding or contracting?), asset turnover (improving efficiency or not?), and the equity multiplier (is debt load growing?). This reveals whether ROE comes from sustainable advantages or financial engineering.
Step 4: Consider the Context
Factor in industry norms, business model characteristics, and company life stage. A mature company in a stable industry with 18% ROE might be exceptional; a high-growth tech company with the same figure might be underperforming. Young companies investing heavily in growth often show lower ROE that improves over time as investments pay off.
Step 5: Validate with Supporting Metrics
Cross-check ROE against free cash flow, debt levels, and capital allocation patterns. A company with strong ROE but weak cash flow might have accounting earnings that don't translate to actual cash. High ROE paired with rising debt-to-equity deserves scrutiny.
When researching specific companies, you can ask questions like "What's the 5-year ROE trend for [ticker]?" using AI-powered research tools that pull data directly from financial statements rather than requiring manual calculation.
Frequently Asked Questions
1. What is the difference between ROE and ROA?
ROE (Return on Equity) measures net income relative to shareholder equity, while ROA (Return on Assets) measures net income relative to total assets. ROE focuses specifically on returns to equity holders and is influenced by leverage, whereas ROA measures overall asset efficiency regardless of capital structure. Companies with significant debt will show higher ROE than ROA because they're generating returns on a smaller equity base.
2. Can ROE be too high?
Yes, extremely high ROE above 30-40% can signal red flags depending on the industry. It might indicate unsustainable leverage, accounting irregularities, or a temporarily depressed equity base from losses or buybacks. Technology companies with asset-light models can legitimately sustain high ROE, but in capital-intensive industries, ROE above 25% often warrants investigation into the underlying drivers.
3. How does share buyback affect ROE?
Share buybacks reduce shareholder equity by removing cash from the balance sheet and often retiring shares. This smaller equity denominator mechanically increases ROE even if net income stays constant. A company buying back 10% of shares will see ROE rise roughly 11% (all else equal). Some investors view this as value creation; others consider it financial engineering that masks operational performance.
4. What ROE did Warren Buffett target for investments?
Warren Buffett has historically looked for companies with ROE above 15% sustained over time, particularly when achieved with minimal debt. In Berkshire Hathaway annual letters, he emphasizes consistent ROE performance over multiple years rather than single-year spikes, and he prefers companies that achieve high ROE through operational excellence rather than leverage.
5. Why might a company have negative ROE?
Negative ROE occurs when a company reports net losses (negative net income) or has negative shareholder equity. Negative equity happens when accumulated losses exceed contributed capital, or when aggressive buybacks reduce equity below zero. Startups and turnaround situations often show negative ROE during periods of heavy investment or restructuring before returning to profitability.
6. How often should you review ROE when tracking stocks?
Review ROE quarterly when companies report earnings to track trends, but focus on annual figures for meaningful analysis since quarterly data can be noisy. Look at 3-5 year trends to filter out one-time events and business cycle effects. Sustained changes in ROE over multiple quarters deserve investigation into underlying causes.
7. What's the relationship between ROE and stock price?
Companies with higher sustained ROE often trade at premium valuations because they generate more earnings from the same equity base, creating compounding potential. However, the relationship isn't linear—markets price in expected future ROE, not just current figures. A company with 25% ROE might trade at a lower multiple than one with 20% ROE if the market expects the first company's returns to decline and the second company's to improve.
8. Should you exclude one-time items when calculating ROE?
For analyzing sustainable earning power, consider calculating ROE using normalized net income that excludes major one-time items like asset sales, restructuring charges, or litigation settlements. This gives a clearer picture of ongoing operational returns. However, also review reported ROE including all items, since management's capital allocation decisions (which create some "one-time" items) affect shareholder returns.
Conclusion
Return on Equity measures how efficiently a company converts shareholder capital into net income—a fundamental gauge of management effectiveness and competitive advantage. While an ROE above 15-20% generally indicates strong performance, context matters: compare against industry peers, examine 5-year trends, and use DuPont analysis to understand whether returns come from operational excellence or financial leverage.
ROE works best as part of a broader analysis that includes other profitability ratios, balance sheet metrics, and cash flow data. Look for companies that sustain above-average ROE through competitive moats rather than increasing debt, and always consider industry norms when interpreting what constitutes a "good" figure.
