What Is Return on Equity (ROE)?
Return on equity (ROE) measures how much profit a company generates for every dollar of shareholders' equity. It's calculated by dividing net income by shareholders' equity — and it's one of the most widely used signals for whether management is deploying capital effectively.
A company with $2.4B in net income and $12B in shareholders' equity has an ROE of 20%. That means for every $1 shareholders have invested in the business, the company returns $0.20 in annual profit.
ROE answers one fundamental question: Is this management team turning investor capital into actual profits?
TL;DR: ROE tells you how efficiently a company uses shareholder capital to generate profit. A consistently high ROE (above 15–20%) suggests a durable competitive advantage. Use the ROE filter on ScreenerHub to focus your screen on genuinely profitable businesses — not just large or fast-growing ones.
Why Return on Equity Matters for Investors
Size and revenue tell you what a company does. ROE tells you how well it does it.
Two companies can have identical revenues and identical profits — and completely different ROEs, depending on how much capital was required to generate those results. A company that earns $50M from $250M in equity (ROE: 20%) is far more efficient than one that earns $50M from $1B in equity (ROE: 5%).
Warren Buffett has long used ROE as a primary filter when evaluating businesses. His preference for companies with ROE consistently above 15% reflects a simple insight: businesses that don't need to reinvest large amounts of capital to grow tend to create far more shareholder value over time.
Here's why ROE belongs in your quality screens:
- Capital efficiency signal. A high, sustained ROE means the business generates strong returns without requiring ever-increasing capital injections.
- Management quality proxy. When ROE stays high across economic cycles, it usually means the management team allocates capital well — not just during boom years.
- Competitive moat indicator. Companies with durable competitive advantages — pricing power, switching costs, network effects — tend to post consistently high ROEs because competitors can't easily replicate their economics.
- Dividend sustainability check. Profitable companies with high ROEs are more likely to sustain and grow dividends over time. A high ROE is the foundation of many dividend investing strategies.
How ROE Is Calculated
The formula draws from two financial statements:
- Net income: The company's total profit after all expenses, interest, and taxes.
- Shareholders' equity: Total assets minus total liabilities — what remains for shareholders if the company settled all its debts.
Worked example:
| Input | Value |
|---|---|
| Net Income | $2.4B |
| Shareholders' Equity | $12B |
| ROE | 20% |
This company earns $2.40 in profit for every $10 shareholders have at stake in the business.
Note: Most screeners use average shareholders' equity over the year (beginning + end ÷ 2) rather than the end-of-year figure. This smooths out the effect of equity changes that occurred during the year. ScreenerHub uses trailing twelve-month net income and average equity to keep the calculation consistent.
How to Interpret ROE
A higher ROE is generally better — but context matters enormously. Sector, capital structure, and the source of a high ROE all affect whether a number is meaningful.
ROE benchmarks
| ROE Range | What It Typically Signals |
|---|---|
| Negative | Net loss or negative equity. ROE is meaningless here; use other profitability metrics instead. |
| Below 5% | Weak capital efficiency. Minimal profit relative to the equity base. |
| 5% – 10% | Below average. May reflect high capital intensity or a business model with limited pricing power. |
| 10% – 15% | Average. Common in regulated industries. Adequate, but not exceptional. |
| 15% – 25% | Above average. Typically signals a well-run business with a meaningful competitive advantage. |
| Above 25% | Strong. Usually indicates a durable moat — or, alternatively, high financial leverage inflating the number. |
⚠️ Context matters: A 30% ROE in the technology sector is outstanding. A 30% ROE in banking may simply reflect high leverage — not exceptional operations. Always compare ROE within the same sector.
ROE by sector (approximate U.S. market averages)
| Sector | Typical ROE Range | Notes |
|---|---|---|
| Technology / Software | 20% – 50%+ | Asset-light models; minimal equity required to scale |
| Consumer Staples | 15% – 35% | Strong brands with pricing power; often boosted by buybacks |
| Healthcare | 15% – 30% | Patent-protected margins; higher in pharma, lower in services |
| Industrials | 10% – 20% | Capital-intensive; moderate but stable returns |
| Financials (Banks) | 8% – 18% | ROE is the primary bank profitability metric; 10–15% is solid |
| Utilities | 8% – 14% | Regulated returns; stable but capped by rate-setting authorities |
| Energy | 5% – 20% | Highly cyclical; ROE fluctuates with commodity prices |
| Real Estate (REITs) | 5% – 15% | Better assessed via FFO yield; ROE is less relevant here |
ROE in a Stock Screener
ROE is one of the most versatile quality filters you can add to a screen. Here are three practical approaches:
Screener 1: Quality companies with consistent profitability
Filter for established businesses that generate strong, sustainable returns.
| Filter | Setting |
|---|---|
| ROE | > 15% |
| Net profit margin | > 10% |
| Market cap | > $1B |
| Debt-to-equity | < 1.0 |
The debt-to-equity filter is critical here. A high ROE combined with high debt suggests the business may be leveraging its way to strong returns — not earning them through operational excellence.
Screener 2: Quality at a reasonable price
Combine ROE with a valuation filter to find companies that are both high-quality and reasonably priced.
| Filter | Setting |
|---|---|
| ROE | > 15% |
| P/E ratio | < 25 |
| Earnings growth (1Y) | > 5% |
| Market cap | > $500M |
This hybrid quality-value screen is the foundation of many "quality at a reasonable price" (QARP) strategies. High ROE confirms operational strength; a moderate P/E ensures you're not overpaying for it.
Screener 3: Quality income stocks
Use ROE as a quality gate when screening for dividend payers.
| Filter | Setting |
|---|---|
| ROE | > 15% |
| Dividend yield | > 2% |
| Payout ratio | < 60% |
| Revenue growth (1Y) | > 3% |
Companies that sustain a high ROE while paying and growing a dividend are compounding machines. The payout ratio filter ensures dividends are covered by earnings — not funded by debt.

When ROE Misleads
ROE is powerful, but three situations can make a high ROE look better than it actually is:
1. High financial leverage artificially inflates ROE
ROE = Net Income ÷ Equity. When a company funds its assets heavily with debt, shareholders' equity shrinks — making ROE look inflated even when the underlying business isn't generating exceptional returns.
Example: A company with $1B in assets, $900M in debt, and $100M in equity earning $20M in net income has an ROE of 20%. But its return on invested capital (ROIC) — which includes debt in the denominator — is only 2%. ROE and ROIC are telling completely different stories.
Mitigation: Always pair ROE with ROIC and debt-to-equity. When ROE is high but ROIC is low, debt is the driver — not operational quality.
2. Share buybacks can shrink equity and boost ROE mechanically
Aggressive share repurchase programs reduce shareholders' equity (buybacks are recorded as negative equity). This mechanically boosts ROE without any change in the underlying business's earnings power.
Mitigation: Check whether equity has been declining steadily over time. Consumer brands and technology companies with long-running buyback programs frequently show ROEs that are elevated by this effect.
3. One-time income items spike net income
An asset sale, tax benefit, or insurance settlement can inflate net income — and therefore ROE — in a single year without reflecting sustainable earnings.
Mitigation: Use a 3- or 5-year average ROE rather than a single year. ScreenerHub displays trailing twelve-month ROE; check the historical trend to spot one-time spikes.
ROE vs. Related Profitability Metrics
ROE doesn't tell the whole story on its own. These metrics used together paint a complete picture:
| Metric | What It Measures | When to Use It |
|---|---|---|
| ROE | Profit relative to shareholders' equity | Primary quality filter; starting point for fundamental screens |
| ROIC | Profit relative to all invested capital | When you need to see through leverage; especially for M&A-heavy firms |
| Net Profit Margin | Profit as a share of revenue | Pricing power analysis; comparison within the same sector |
| ROA | Profit relative to total assets | Asset-heavy industries; useful for banks and real estate |
Rule of thumb: Start with ROE for a quick quality check. If ROE is high, validate with ROIC. If both are high, the business is generating genuine returns — not just leveraging its balance sheet.
Frequently Asked Questions
What is a good ROE for a stock?
There is no single "good" ROE — it depends on the sector. As a general benchmark, an ROE above 15% suggests solid capital efficiency in most industries. In high-margin sectors like software or consumer brands, the bar is typically higher (20–30%+). In capital-intensive sectors like utilities or banking, 10–15% is considered strong. Always compare within the same sector, not against the broad market average.
How does ROE differ from ROIC?
ROE measures profit relative to shareholders' equity only. ROIC measures profit relative to all invested capital — both equity and debt. A company with heavy debt loads can show a high ROE while generating poor returns on the total capital deployed. ROIC removes that distortion, making it a more reliable measure of true capital efficiency for leveraged businesses.
Can ROE be negative? What does it mean?
Yes. A negative ROE means either net income is negative (the company is losing money) or shareholders' equity has turned negative (often from accumulated losses or aggressive buybacks exceeding retained earnings). In both cases, ROE loses its meaning as a profitability signal and should be replaced by other metrics like net profit margin or cash flow measures.
Why do value investors pay so much attention to ROE?
ROE is a proxy for a durable competitive advantage. A business that consistently earns high returns on equity year after year — without needing to raise ever-larger amounts of capital — is compounding shareholder wealth efficiently. This pattern is the hallmark of businesses with genuine moats: brands, switching costs, or network effects that prevent competitors from eroding their returns.
