Return on equity (ROE): Definition, Formula, Analysis

Return on Equity

Return on equity (ROE) measures how effectively a business turns shareholders’ equity into profit, expressed as a percentage. For accountants, advisors, and finance executives, it’s one of the quickest ways to determine whether the company’s strategies are yielding sufficient returns in relation to the owners’ investments. While low or declining ROE may indicate margin pressure, poor asset utilisation, or an ineffective capital structure, high or improving ROE may indicate strong profitability, operational efficiency, or effective use of leverage.

This KPI glossary explains the return on equity formula, how to calculate it through a step-by-step example, its application in performance assessment, and how businesses can use ROE to identify opportunities for improvement or potential risks.

What is return on equity (ROE)?

Key takeaways

  • The return on equity ratio answers the question, "How efficiently is this business turning equity into profit?” and highlights profitability, leverage, and capital-structure risks in a single metric.
  • Return on equity analysis becomes far more powerful when paired with EBIT, operating profit margin, debt to total assets, ROA, ROIC, and DuPont analysis.
  • Financial reporting software can help automate ROE tracking, scenario modelling, and cash flow forecasting, making it easier for firms to standardise analysis.

How return on equity works

According to the Corporate Finance Institute, return on equity is used in corporate finance as a core measure of how effectively a company generates returns on shareholders’ capital.  

Several factors that influence the return on equity:  

  • Profitability - how much income the business generates
  • Operational efficiency - how well assets generate revenue
  • Financial leverage - the way the company uses debt in relation to equity
  • Capital structure - how the business is funded across equity and liabilities

A “good” or “bad” return on equity depends on industry standards, business maturity, and peer benchmarks (as noted by sources like Investopedia), which is why understanding what is return on equity ratio in context is important for accurate interpretation.

For example, a company with a high ROE may be generating strong earnings relative to its equity base. However, ROE can also be inflated by excessive leverage. This is why it’s important to examine metrics such as the debt-to-total-assets ratio when interpreting return on equity.

Why return on equity matters

The return on equity has multiple strategic purposes for businesses:

  • Evaluating performance results: Return on equity ties directly to management effectiveness and profitability trends.
  • Supporting advisory and forecasting work: Return on equity is used in growth forecasts, valuation analysis, and cash flow forecasting models.
  • Assessing long-term sustainability: A declining ROE may be a sign of failing operations, inadequate margins, or inefficiencies in the business.
  • Benchmarking and comparison: When comparing businesses in the same sector or operating environment, return on equity is crucial.
  • Capital allocation insight: A high ROE indicates that capital is being reinvested efficiently, promoting long-term, sustainable growth.

Return on equity formula and calculation

To find out how to calculate the return on equity, you use the formula below:

Return on equity = Annualised net income / Opening total equity x 100

This rate of return on equity formula focuses on the opening equity balance, which helps standardise period-to-period comparison.

Step-by-step return on equity calculation

To calculate return on equity, follow these steps:

  1. Identify annualised net income
  2. Determine opening total equity
  3. Apply the return on equity formula

As an example, you can apply the rate of return on equity formula like below:

Company A reports:

  • Annualised net income: $420,000
  • Opening total equity: $2,400,000

Using the rate on equity ratio formula:

Return on equity = (420,000 / 2,400,000) x 100 = 17.5%

The 17.5% ROE shows that the business generated 17.5 cents of profit for every $1 of equity invested at the start of the period.

Using return on equity for performance evaluation

Return on equity is widely used across financial analysis because it offers a simple but valuable connection between earnings and the capital base needed to generate those earnings.

When evaluating a business, the rate of return on equity formula helps provide answers to questions such as:

  • Given the risks taken, is management generating sufficient returns?
  • Is the company improving or weakening its long-term value creation?
  • Are profits growing efficiently, or are they being driven by excessive leverage?
  • How does performance stack up against industry peers or market expectations?

A consistently high ROE typically indicates that the business is competitively positioned, runs effectively, and makes wise capital allocations.  

A declining or inconsistent ROE, on the other hand, might be a sign of more serious problems like margin pressure, bad investment choices, a weakening balance sheet, or declining asset productivity.

Sustainable growth rate

The sustainable growth rate (SGR) is closely tied to return on equity because it gauges how quickly a business can expand using internally generated funds without needing additional external equity.  

The traditional model is:

SGR = Return on equity x Retention ratio

The retention ratio represents the proportion of profits reinvested back into the business.

For accounting professionals and advisors, SGR is valuable because it:

  • Indicates whether current growth levels are financially sustainable
  • Assists in forecasting future capital needs
  • Provides early warning of over-expansion
  • Strengthens advisory conversations around dividend policy and reinvestment strategies

A business with high ROE and a high retention ratio may be capable of growing rapidly without putting strain on its balance sheet. However, a company with modest ROE but high reinvestment may be destroying value if returns fail to exceed the cost of capital.

Future growth rate

Return on equity also plays a central role in estimating future growth potential.

Return on equity is used to connect profitability with growth assumptions in valuation work, particularly in discounted cash flow, dividend discount models, and residual income models. If the company's capital structure and margin performance stay constant, a steady and well-supported ROE suggests that earnings growth may continue at a consistent rate.

When using return on equity as a growth predictor, it’s important to consider:

  • Whether ROE improvements come from stronger operations or higher leverage
  • The sustainability of current margins
  • The volatility of income streams
  • Macroeconomic factors influencing revenue or asset productivity
  • How ROE compares to historical trends and industry standards

Even though the return on equity metric is a reliable predictor of future growth, it shouldn't be used alone. When ROE is combined with cash flow performance, ROA, ROIC, and operating profit margin, it allows a more holistic understanding of long-term earnings capacity.

Comparing return on equity across companies and industries

Return on equity becomes significantly more insightful when used for benchmarking. Because industries vary in capital intensity, cost structure, and profitability models, ROE norms differ widely.

For example:

  • Asset-heavy industries (such as manufacturing, energy, transport) often see lower ROE, because they require more capital investment.
  • Asset-light industries (such as technology, consulting, and professional services) tend to report higher ROE due to low fixed asset requirements and higher margins.

Hence, when comparing ROE across businesses, you should consider:

  • Business model differences
  • Regulatory and economic context
  • Stage of business growth
  • Capital structure impact
  • Multi-year trend analysis

Interpreting return on equity results

Context is necessary when interpreting the return on equity ratio, especially because ROE norms differ across industries. Generally:

  • Strong ROE (typically 15–25%) could suggest solid profitability and effective use of equity capital.
  • Very high ROE (30% or more) could signal exceptional performance in high-margin industries.
  • Low or declining ROE could be the result of falling margins, operational inefficiencies, or capital misallocation.

Nevertheless, return on equity should be reviewed further alongside EBIT margins, cash flow quality, and other asset efficiency ratios for a well-rounded assessment.

Risk identification through return on equity

Other than being a performance metric, return on equity also acts as a lens to flag any emerging risk areas and uncover other structural issues.  

  1. Inconsistent or declining profits

    Volatile or deteriorating return on equity often points to:

    • Unpredictable earnings
    • Margin compression
    • Weak operating performance
      Poor expense management
  2. Excessive leverage inflating ROE

    Return on equity may increase due to falling equity, rather than because the company is doing better. This is because excessive leverage can conceal operational flaws and make a company more susceptible to downturns.

    Signs of risk include:

    • Rising debt to total assets
    • ROE is increasing faster than EBIT or operating profit margin
    • Diminishing equity base
    • Reduced interest coverage
  3. Declining asset efficiency

    When assets don't produce enough income or return, ROE may decrease. This risk often becomes more visible when comparing ROE with ROA or the asset turnover component.

    A decline in asset efficiency may indicate:

    • Inadequate use of assets
    • Inefficient capital investments
    • Underperforming subsidiaries or product lines
    • Poor management of working capital
  4. Weak cash flow quality

    A company may report high return on equity despite weak cash flow. This issue becomes clear when the return on equity is analysed alongside cash flow forecasting and EBITDA trends.

    The warning signs that point to this include:

    • ROE increases while operating cash flow declines
    • Heavy reliance on funding to cover operations
    • Earnings boosted by accruals or accounting adjustments
    • Inconsistency or misalignment between profit and cash generation
  5. Capital allocation risk

    The way a company distributes shareholder capital has a significant impact on the return on equity. If management makes investments in low-return projects, even profitable businesses may experience declining ROE.

    Common indicators include:
    • Investing in long-payback or low-yield projects
    • Acquisitions that reduce earnings
    • Excessive cash is invested in underperforming assets
    • Capital expenditures increase without margin or revenue gains

Return on equity variations and related metrics

ROE vs. Return on assets (ROA)

ROA measures profitability relative to total assets, whereas ROE focuses on equity only.  

ROA formula = Annualised earnings before interest and tax / Total assets x 100

ROA is less affected by leverage and reflects operational efficiency regardless of capital structure. Comparing ROA and ROE can reveal how heavily a firm depends on debt.

ROE vs. Return on invested capital (ROIC)

ROIC measures returns generated from all long-term capital (debt and equity).

ROIC is useful because it reflects total investment efficiency and removes distortions caused by capital structure. For instance, a company with high ROE but low ROIC often relies too heavily on debt.

These comparisons provide context for interpreting the return on equity ratio formula in a broader performance framework.

Return on equity and DuPont analysis

DuPont analysis expands the return on equity into three key drivers, offering a deeper look at the underlying performance factors.

The DuPont formula is as follows:

Return on equity = Net profit margin x Asset turnover x Equity multiplier

Where:

  • Net profit margin = Net income / revenue
  • Asset turnover = Annualised revenue / Total assets
  • Equity multiplier (financial leverage) = Total assets / equity

This helps you identify whether the return on equity improvements come from:

  • Higher profitability
  • Operational efficiency
  • Increased leverage

Limitations of return on equity

Return on equity is a powerful metric, but it has limitations that you must consider when interpreting results.

  • Industry comparisons: Return on equity varies significantly between industries.
  • Effect of leverage: Leverage can inflate ROE without improving operational performance. Always compare ROE with leverage ratios such as debt to total assets.
  • Short-term distortions: Changes in equity or one-off gains can change ROE results. Analysing with EBIT, ROA, ROIC, and margin metrics can help provide balance.
  • Negative or near-zero equity: When equity is very low or negative, ROE becomes unreliable because the denominator skews the calculation, making the ratio difficult to interpret.

Final thoughts

Return on equity is an important metric in financial analysis, helping accountants, advisors, and investors evaluate performance, capital efficiency, and long-term sustainability. Although return on equity provides insight into how well a company turns equity into profit, it must be viewed alongside complementary metrics such as ROA, ROIC, leverage ratios, and industry benchmarks.  

As part of a larger performance-measurement framework, return on equity can truly be a useful tool for assessing the financial health of a business, identifying risks, and driving strategic decision-making.

Frequently asked questions (FAQs)

What is considered a good return on equity (ROE)?

A “good” return on equity depends heavily on the industry. Generally, 10%–20% is considered healthy for many sectors. High-growth service businesses may exceed 25% or more.

What happens if ROE is negative?

Negative ROE occurs when net income is negative or opening equity is negative. It generally indicates poor profitability or financial stress.

What causes ROE to increase?

ROE can rise due to higher net income, improved operating efficiency, better margins, and share buy backs that reduce equity.

What’s the difference between ROE and ROA?

ROE measures return to shareholders. ROA measures the return generated by total assets. ROA is less influenced by leverage and gives a clearer view of operational efficiency.

How do investors use ROE?

Investors use ROE to assess management effectiveness, evaluate long-term value creation, benchmark companies, and estimate sustainable growth potential.
