What Is a Good ROE? A Complete Guide to Return on Equity for Stock Investors
What Is ROE?
ROE (Return on Equity) is one of the most important profitability ratios used by investors to evaluate a company’s ability to generate profits from shareholders’ equity.
In simple terms, ROE answers this question:
How efficiently does a company use shareholders’ money to generate profits?
The basic formula is:
ROE = Net Income ÷ Average Shareholders’ Equity × 100
For example, if a company generates $20 million in net income and has $100 million in average shareholders’ equity:
ROE = $20 million ÷ $100 million × 100 = 20%
This means the company generated approximately $20 of profit for every $100 of shareholders’ equity.
Investor.gov defines ROE as a measure based on a company’s net income relative to shareholders’ equity.
ROE is widely used in fundamental stock analysis because it helps investors evaluate profitability and management effectiveness. Fidelity notes that ROE is generally calculated using annual earnings divided by average shareholders’ equity, although a higher ROE does not automatically mean better financial performance.
What Is Considered a Good ROE?
There is no single ROE number that is considered good for every company.
However, as a general starting point for analyzing profitable non-financial companies:
| ROE | General Interpretation |
|---|---|
| Below 5% | Weak |
| 5%–10% | Below average |
| 10%–15% | Moderate |
| 15%–20% | Good |
| 20%–30% | Very good |
| Above 30% | Excellent, but requires further investigation |
These ranges are general guidelines, not strict rules.
The most important question is not simply whether a company has an ROE of 20%, 30%, or 40%.
Instead, investors should ask:
Is the company’s ROE consistently high, and is it being generated without excessive financial leverage or accounting distortions?
Fidelity emphasizes that ROE should be used to compare a company with its historical performance and similar companies, because a “good” level can vary significantly by industry.
Why Is a High ROE Important?
A high ROE can indicate that a company is efficient at converting shareholders’ capital into profits.
Imagine two companies:
Company A
- Shareholders’ equity: $1 billion
- Net income: $100 million
- ROE: 10%
Company B
- Shareholders’ equity: $1 billion
- Net income: $250 million
- ROE: 25%
If the businesses have similar risk profiles and accounting characteristics, Company B is generating significantly more profit from the same amount of shareholders’ equity.
This can be an attractive characteristic for long-term investors.
Charles Schwab describes ROE as an important ratio for assessing how effectively management turns shareholders’ capital into profits and notes that comparing ROE with peers can help investors evaluate management effectiveness.
Is a 20% ROE Good?
Generally, yes.
A sustained ROE of around 20% can be considered strong for many profitable companies.
For example:
A company has:
- Net income: $2 billion
- Average shareholders’ equity: $10 billion
Its ROE is:
$2 billion ÷ $10 billion = 20%
This means the company generated $0.20 of annual profit for every $1 of average shareholders’ equity.
However, investors should not immediately conclude that a stock with a 20% ROE is a great investment.
You should also investigate:
- Debt levels
- Free cash flow
- Revenue growth
- Profit margins
- Competitive advantages
- Share buybacks
- Industry averages
- Historical ROE
A high ROE is more meaningful when it is consistent and supported by strong underlying economics.
Is a 30% ROE Good?
A 30% ROE is usually very strong, but it deserves closer analysis.
Companies capable of consistently generating 30% ROE can possess attractive characteristics such as:
- Strong brands
- High profit margins
- Capital-light business models
- Competitive advantages
- Pricing power
- Efficient capital allocation
However, there is an important warning:
A very high ROE can sometimes be caused by excessive debt rather than exceptional business quality.
For example, a company can increase its ROE by using more debt and reducing the amount of equity supporting its assets.
Therefore:
High ROE + low debt = potentially attractive
while:
High ROE + excessive debt = requires caution
Can a Company Have an ROE Above 50%?
Yes.
Some companies can report ROEs of:
- 40%
- 50%
- 70%
- 100% or more
But an extremely high ROE should immediately make investors ask:
Why is ROE so high?
There are several possible explanations.
1. Exceptional profitability
The company may genuinely have an excellent business model.
2. Low equity
If shareholders’ equity is relatively small, even moderate profits can produce a very high ROE.
3. Large share buybacks
Share repurchases reduce shareholders’ equity in many accounting situations, which can mechanically increase ROE.
4. High financial leverage
Debt can amplify returns to shareholders while also increasing risk.
5. Accounting effects
One-time gains, asset write-downs, or other accounting events can distort ROE.
Therefore, an extremely high ROE is not automatically better than a 20% ROE.
Why Should Investors Compare ROE With Industry Peers?
One of the biggest mistakes investors make is comparing ROE across completely different industries.
For example:
- A technology company
- A bank
- A retailer
- A utility company
can have very different capital structures and business models.
Therefore, an ROE of 15% may mean different things in different industries.
A better approach is:
Company ROE → Industry average → Competitors → Company’s historical ROE
Fidelity recommends comparing financial ratios against previous company results and similar companies because industry characteristics can significantly affect these measures.
Charles Schwab similarly notes that many investors use financial ratios to compare companies within the same industry group.
What Is a Good ROE for Banks?
ROE is particularly important when analyzing banks and other financial companies.
For a bank, shareholders’ equity represents an important part of the capital supporting its balance sheet.
A bank with a consistently strong ROE may be using its capital efficiently.
However, investors should not evaluate banks using ROE alone.
You should also examine:
- Return on assets (ROA)
- Net interest margin
- Loan growth
- Credit quality
- Nonperforming loans
- Capital ratios
- Provision for credit losses
- Book value growth
For financial companies, a high ROE can be attractive, but excessive leverage and poor credit quality can make that ROE less sustainable.
What Is a Good ROE for Technology Companies?
Technology companies can sometimes generate exceptionally high ROEs because many technology businesses are relatively capital-light.
For example, a software company may not need large amounts of physical assets to generate substantial profits.
A technology company with:
- ROE above 20%
- Strong revenue growth
- High margins
- Positive free cash flow
- Low debt
- Recurring revenue
could have an attractive financial profile.
However, investors should still investigate whether the ROE is being boosted by share repurchases or low book equity.
ROE vs. ROA: What’s the Difference?
ROE and ROA are related but measure different things.
ROE
ROE = Net Income ÷ Average Shareholders’ Equity
It measures the return generated on shareholders’ capital.
ROA
ROA = Net Income ÷ Average Total Assets
It measures how efficiently the company uses its assets to generate profit.
Fidelity defines ROA as a measure of profit generated relative to total assets and notes that comparisons are most useful against the company’s historical results or similar companies.
Consider a company with:
- Net income = $100 million
- Equity = $500 million
- Assets = $2 billion
ROE:
$100M ÷ $500M = 20%
ROA:
$100M ÷ $2B = 5%
The company has a 20% ROE but only a 5% ROA.
That difference can provide useful information about the company’s capital structure and leverage.
ROE vs. ROIC: Which Is Better?
Another important ratio is ROIC (Return on Invested Capital).
ROIC evaluates how effectively a company generates operating returns from the capital invested in the business.
ROE focuses specifically on shareholders’ equity.
ROIC considers a broader pool of capital, including debt and equity.
For this reason, investors often use:
ROE + ROIC
rather than relying on ROE alone.
If a company has:
- High ROE
- High ROIC
- Low debt
that can be a particularly encouraging combination.
But if a company has:
- Very high ROE
- Low ROIC
- High debt
investors should investigate whether leverage is artificially boosting returns to shareholders.
FINRA includes ROE, ROA, and ROIC among the key profitability metrics used in financial analysis.
The DuPont Analysis: Understanding Why ROE Is High
One of the best ways to analyze ROE is through the DuPont framework.
The basic three-part DuPont formula is:
ROE = Net Profit Margin × Asset Turnover × Financial Leverage
This breaks ROE into three components.
1. Net Profit Margin
Measures how much profit the company generates from its revenue.
2. Asset Turnover
Measures how efficiently the company uses its assets to generate revenue.
3. Financial Leverage
Measures how much assets are supported by shareholders’ equity.
This is extremely useful because two companies can have the same ROE for completely different reasons.
For example:
Company A
- High profit margins
- Efficient asset utilization
- Moderate debt
Company B
- Low profit margins
- Lower asset efficiency
- Very high leverage
Both could have a 25% ROE.
But Company A may have a much stronger underlying business.
High ROE vs. Sustainable ROE
This distinction is extremely important.
A company with a 40% ROE for one year is not necessarily better than a company with a 20% ROE maintained for 15 years.
Long-term investors should focus on:
Consistency + Sustainability + Quality
For example:
| Year | Company A ROE | Company B ROE |
|---|---|---|
| Year 1 | 40% | 19% |
| Year 2 | 18% | 21% |
| Year 3 | 12% | 22% |
| Year 4 | 8% | 20% |
| Year 5 | 5% | 21% |
Company A had the highest ROE initially.
But Company B demonstrated much greater consistency.
For a long-term investor, Company B may be more interesting because its profitability appears more durable.
What Causes ROE to Increase?
ROE can increase for several reasons.
Higher net income
If profits rise while equity remains relatively stable, ROE increases.
Better profit margins
A company that becomes more efficient can generate more profit from the same revenue.
More efficient use of assets
Higher asset turnover can increase ROE.
Share buybacks
Repurchasing shares can reduce shareholders’ equity and increase ROE mechanically.
More debt
Higher leverage can increase ROE, although it also increases financial risk.
This is why investors should always ask:
What caused the ROE to increase?
The answer is often more important than the ROE number itself.
What Causes ROE to Decline?
ROE can decline because of:
- Falling profits
- Lower profit margins
- Excess equity accumulation
- Weak asset utilization
- Higher expenses
- Business deterioration
- Industry downturn
- Poor capital allocation
A declining ROE over several years can be an early warning sign that a company’s competitive position or profitability is weakening.
Is a High ROE Always Good?
No.
This is perhaps the most important lesson when using ROE.
Fidelity explicitly warns that although higher ROE values are generally favorable, a higher ROE does not necessarily mean better overall financial performance.
Consider two companies:
Company A
- ROE: 35%
- Debt-to-equity: 0.3
- Strong free cash flow
- Stable margins
Company B
- ROE: 45%
- Debt-to-equity: 3.0
- Weak cash flow
- High interest expenses
Company B has the higher ROE.
But Company A may have the stronger financial profile because its return is generated with substantially less leverage.
How Investors Should Use ROE When Analyzing Stocks
A practical ROE checklist can look like this:
Step 1: Check the current ROE
Is it above or below the industry average?
Step 2: Check the historical ROE
Has the company maintained a strong ROE over 5–10 years?
Step 3: Compare competitors
Does the company have a higher ROE than similar businesses?
Step 4: Check debt
Is the high ROE being supported by excessive leverage?
Step 5: Check ROA
A large difference between ROE and ROA may indicate significant leverage.
Step 6: Check ROIC
Does the company generate attractive returns on the total capital invested in the business?
Step 7: Check free cash flow
Are reported profits translating into actual cash generation?
Step 8: Investigate the reason for the ROE
Is it driven by:
- Strong margins?
- Competitive advantages?
- Efficient operations?
- Share buybacks?
- Debt?
This final question is crucial.
What ROE Should Value Investors Look For?
Value investors often look for companies that combine:
Reasonable valuation + High-quality ROE + Sustainable growth
For example, a company with:
- ROE: 25%
- ROIC: 18%
- P/E: 15
- Strong free cash flow
- Low debt
- Stable earnings
may deserve further research.
By contrast, a company with:
- ROE: 40%
- P/E: 60
- High debt
- Declining revenue
may not be attractive despite its high ROE.
Therefore:
ROE tells you something about business quality, but it does not tell you whether the stock is cheap.
For valuation, investors should combine ROE with metrics such as:
- P/E
- P/B
- PEG
- Free cash flow yield
- EV/EBITDA
What Is More Important: ROE or P/E?
They answer different questions.
ROE asks:
How efficiently does the company generate profits from shareholders’ equity?
P/E asks:
How much is the market willing to pay for those earnings?
A company can have:
High ROE + Low P/E
which can be an interesting combination for value investors.
It can also have:
Low ROE + High P/E
which may indicate that investors are paying a premium for weak current profitability because they expect future improvement.
This is why combining profitability and valuation metrics can produce a more complete picture.
ROE and Warren Buffett’s Investment Philosophy
ROE is often associated with quality investing because it can help investors identify businesses capable of generating strong returns on shareholders’ capital.
However, investors should not assume that a high ROE alone makes a company attractive.
A high-quality business typically combines:
- High returns on capital
- Strong competitive advantages
- Sustainable earnings
- Strong cash generation
- Sensible debt levels
- Capable management
- Attractive reinvestment opportunities
Charles Schwab notes that ROE can help investors assess how effectively management turns shareholder capital into profits.
The key is sustainable high returns, not simply a high number in one particular year.
A Simple Rule for Evaluating ROE
If you want a simple framework, you can start with:
ROE below 10%
Investigate carefully.
The business may have low profitability or operate in a structurally low-return industry.
ROE of 10%–15%
Moderate.
Compare it with competitors and historical performance.
ROE of 15%–20%
Generally good.
This can indicate attractive profitability for many businesses.
ROE of 20%–30%
Very good.
Investigate whether the company can sustain this level.
ROE above 30%
Excellent but investigate carefully.
Determine whether the high ROE comes from exceptional business economics or excessive leverage, buybacks, or unusually low equity.
Final Thoughts: What Is a Good ROE?
So, what is a good ROE?
As a general rule, an ROE of 15% or higher can be considered attractive for many profitable non-financial companies, while 20%+ is often viewed as strong.
But the number alone is not enough.
The best ROE is not necessarily the highest ROE.
What investors should look for is:
High + Consistent + Sustainable + Low-Leverage ROE
A company that consistently generates a 20% ROE with strong free cash flow, manageable debt, and a durable competitive advantage may be much more attractive than a company reporting a temporary 50% ROE because of leverage or accounting effects.
When analyzing a stock, consider ROE together with:
ROE + ROIC + ROA + Debt + Free Cash Flow + Revenue Growth + P/E + Competitive Advantage
This combination can give investors a much clearer picture of both business quality and investment potential.
