ROE (Return on Equity)
Quick Definition
ROE measures how much profit a company produces for every dollar that shareholders have invested. The formula is net income divided by average shareholder equity, expressed as a percentage. A company with $10 million in net income and $50 million in equity has an ROE of 20%, meaning it generates 20 cents of profit per dollar of owner capital.
What It Means
ROE is the single most widely used profitability ratio in equity investing. It tells you whether a company is putting shareholder money to work effectively or letting it sit idle. A business that earns 25% ROE is compounding owner capital far faster than one earning 8%, and over a decade that difference creates an enormous gap in value.
The S&P 500 aggregate ROE reached approximately 20.8% in the first quarter of 2026, an all-time record according to History of Market. The long-run average going back to 1960 is about 13.8%, which means current profitability is running roughly 50% above the historical norm. However, Goldman Sachs research from mid-2026 found that seven mega-cap technology companies hold a combined ROE of about 44%, nearly double the index average. The record is concentrated in a handful of stocks rather than reflecting broad corporate health.
Industry context changes the interpretation dramatically. NYU professor Aswath Damodaran's ROE data, updated January 2026, shows the total market across 5,994 firms at 17.21% unadjusted ROE. Aerospace and defense averages 15.27%. Apparel runs 10.42%. Auto manufacturers sit at just 3.16%. Comparing a software company's 40% ROE to a steel company's 8% without accounting for industry differences leads to poor investment decisions.
How It Works
The Formula
ROE = Net Income / Average Shareholder Equity
Average equity is used because net income accumulates over the full year, not on the final day. Calculate it as (beginning equity + ending equity) / 2.
Worked Example
A company reports $80 million in net income for the year. Shareholder equity was $400 million at the start and $480 million at the end. Average equity is $440 million.
ROE = $80M / $440M = 18.2%
The DuPont Breakdown
ROE alone tells you the result but not the cause. The DuPont formula splits ROE into three drivers:
ROE = Net Profit Margin x Asset Turnover x Equity Multiplier
- Net Profit Margin: Net Income / Revenue. How much of each sales dollar becomes profit.
- Asset Turnover: Revenue / Total Assets. How efficiently assets generate sales.
- Equity Multiplier: Total Assets / Total Equity. How much the company relies on debt.
Two companies with identical 20% ROE can have very different risk profiles. One might get there through high margins and zero debt. The other might use thin margins and heavy borrowing. The first is a higher-quality business. The second carries more risk because debt amplifies losses during downturns.
Real-World Examples
Top ROE Stocks in August 2026
Billiver's ROE rankings show several S&P 500 companies with extreme ROE figures:
| Company | Sector | ROE |
|---|---|---|
| Choice Hotels (CHH) | Consumer Discretionary | 255.1% |
| Fortinet (FTNT) | Information Technology | 254.9% |
| Mastercard (MA) | Financials | 180.3% |
| Home Depot (HD) | Consumer Discretionary | 120.3% |
| Nvidia (NVDA) | Information Technology | 83.4% |
ROE above 100% has two common explanations. First, asset-light businesses like Mastercard need little equity because they lack factories and inventory. Their high ROE reflects genuine capital efficiency. Second, aggressive share buybacks shrink equity on the balance sheet, inflating ROE even if net income is flat. Both can be legitimate, but the second is an accounting effect rather than operational improvement.
The Leverage Trap
| Metric | Company A | Company B |
|---|---|---|
| Net Income | $50M | $50M |
| Shareholder Equity | $400M | $100M |
| Total Debt | $0 | $500M |
| ROE | 12.5% | 50% |
Company B has four times the ROE of Company A, but it carries $500 million in debt. If operating income drops 20%, Company A loses some profit but keeps its equity intact. Company B faces interest payments that can wipe out equity entirely. The high ROE is real, but it comes with substantially more risk.
ROE and the Cost of Equity
ROE only creates value when it exceeds the company's cost of equity capital. If a company earns 10% ROE but its shareholders expect a 12% return given the risk profile, the business is destroying value. The spread between ROE and cost of equity determines whether a company is creating or destroying shareholder wealth.
This is why two companies with identical 15% ROE can have different valuations. A stable consumer staples company with a 7% cost of equity and 15% ROE is creating 8 percentage points of excess return. A volatile biotech with a 16% cost of equity and 15% ROE is destroying 1 percentage point. The ROE number alone does not tell you whether value is being created. You need to compare it to what investors demand for bearing the risk.
Sustainable Growth Rate
ROE also determines how fast a company can grow without raising external capital. The sustainable growth rate formula is:
Sustainable Growth Rate = ROE x (1 - Dividend Payout Ratio)
A company with 20% ROE and a 30% payout ratio can grow earnings at 14% per year using only retained earnings. If it wants to grow faster, it must issue new shares or take on debt. Investors who buy growth stocks should check whether the growth rate is sustainable given the ROE and payout ratio, or whether the company will need to dilute shareholders or increase leverage to maintain its trajectory.
Key Points to Remember
- The S&P 500 average ROE of 20.8% in Q1 2026 is a record, driven by mega-cap tech concentration. The long-run average is about 14%.
- Always compare ROE within the same industry. A 12% ROE is strong for a bank but weak for a software company.
- Use the DuPont decomposition to check whether ROE comes from margins, efficiency, or debt. ROE driven by leverage is riskier than ROE driven by operations.
- ROE above 100% often signals heavy share buybacks that have shrunk the equity base. Investigate whether the ratio reflects business quality or financial engineering.
- Track ROE over 5 to 10 years. Consistency through economic cycles signals a durable competitive advantage.
- Negative shareholder equity makes ROE meaningless. Use alternative metrics like ROIC in those cases.
Common Mistakes to Avoid
Comparing ROE across industries. A 20% ROE might be average in retail but exceptional in utilities. Damodaran's 2026 data shows sector ROE ranging from 3% in autos to 36% in advertising. Always benchmark against industry peers, not the market average.
Ignoring debt. The equity multiplier in the DuPont formula reveals how much of ROE comes from leverage. A company with a 5x equity multiplier is taking on significant risk to achieve its ROE. Check the debt to equity ratio alongside ROE to understand the risk profile.
Mistaking buyback-driven ROE for operational improvement. When a company repurchases shares, equity shrinks and ROE rises without any change in profitability. If net income is flat but ROE is climbing, buybacks are likely the cause. This is not necessarily bad, but it is not the same as the business getting better.
Relying on a single year. One year of high ROE can come from a one-time tax benefit, an asset sale, or a temporary margin spike. Look at multi-year averages to separate consistent performers from lucky streaks.
Using ROE when equity is negative. If accumulated losses exceed paid-in capital, equity goes negative. Dividing positive net income by negative equity produces a negative ROE that is mathematically correct but economically meaningless. Switch to return on invested capital or return on assets instead.
Related Concepts
ROE connects to several other metrics that provide a fuller picture of business quality. For the complete treatment of this concept, see the Return on Equity guide. ROIC measures returns on all capital (debt plus equity) and is harder to manipulate through leverage. Earnings per share is the per-share profit figure that ROE ultimately drives. The debt to equity ratio shows how much of the equity multiplier comes from borrowing versus organic equity. Asset turnover is one of the three DuPont components. Book value represents the equity denominator in the ROE formula. The dividend payout ratio shows how much of ROE-generated profit returns to shareholders. For evaluating whether a stock's ROE justifies its price, valuation methods provide the pricing context. You can also use our investment return calculator to model how returns compound over time. The SEC's EDGAR database provides the filings needed to calculate ROE from primary sources.
Frequently Asked Questions
Q: What is a good ROE?
A: Above 15% is generally considered solid, but it depends on the industry. The S&P 500 average in 2026 is about 20.8%, though that is inflated by mega-cap tech. For banks, 10% to 12% is typical. For software, 20% to 30% is common. Always compare to the industry average.
Q: Can ROE be too high?
A: Yes. ROE above 50% or 100% often means shareholder equity has been reduced to a very small number through buybacks or accumulated losses. The business may be profitable, but the extreme ratio can be misleading and may signal undercapitalization or excessive debt.
Q: How is ROE different from ROIC?
A: ROE measures returns on equity only, while ROIC measures returns on all invested capital (debt plus equity). ROIC is harder to manipulate through capital structure changes and is generally considered the better single metric for evaluating business quality. Many analysts use both together.
Q: Why do some companies have negative ROE?
A: Negative ROE happens when net income is negative (the company is losing money) or when shareholder equity is negative (liabilities exceed assets). If equity is negative, the ratio becomes meaningless and should not be used. Switch to ROIC or return on assets instead.
Q: Should I use ROE or ROA?
A: ROA measures profit relative to total assets, while ROE measures profit relative to equity only. The difference is leverage. If a company has no debt, ROA and ROE are identical. As debt increases, ROE rises above ROA. ROA gives a cleaner view of operational efficiency, while ROE shows the return to shareholders after accounting for the capital structure.
