Return on Equity (ROE) Calculation and What It Means


In the world of finance, one metric stands out as a powerful indicator of a company's financial prowess - Return on Equity (ROE). This article dives into the depths of ROE, explaining its definition, calculation, significance, and limitations.

What Is Return on Equity (ROE)?

Return on Equity (ROE) is a crucial financial performance metric. It gauges a company's efficiency in generating profits by comparing its net income to shareholders' equity. Shareholders' equity, the difference between a company's assets and debts, represents the net assets of the company. ROE, expressed as a percentage, provides valuable insights into a corporation's profitability and management efficiency.

Key Takeaways

1. ROE Calculation: ROE is calculated by dividing net income by shareholders' equity.

2. Profitability Gauge: It measures a company's profitability and efficiency in converting equity financing into profits.

3. Industry Variability: ROE can vary significantly depending on the industry or sector in which the company operates.

Calculating Return on Equity

The formula to calculate ROE is straightforward:

ROE = Net Income / Shareholders' Equity

However, the nuance lies in ensuring that this calculation is based on average equity over a specific period. This practice is essential due to the discrepancy between income statement and balance sheet timelines.

What ROE Reveals

The interpretation of ROE varies across industries. For example, utilities may have lower ROE figures, around 10% or less, due to their substantial assets and debt compared to net income. Conversely, technology or retail firms with smaller balance sheets relative to net income may exhibit ROE levels of 18% or more.

In general, it's advisable for a company to aim for an ROE that matches or surpasses its industry average. This suggests efficient utilization of assets to generate profits. An ROE near the S&P 500 long-term average (around 13.29% as of Q4 2022) is considered acceptable, while anything below 10% is usually seen as poor.

ROE and Stock Performance

ROE isn't just a financial metric; it's also a tool for estimating sustainable growth rates and dividend growth rates. Assuming ROE aligns with peer group averages, it can be used to predict a company's future growth rate and dividend prospects. The retention ratio, the percentage of net income reinvested in the company, plays a key role in these calculations.

Identifying Problems with ROE

While a high ROE is often seen as positive, it's not without caveats. Extraordinary ROE figures can signal underlying issues, such as inconsistent profits, excess debt, or even negative net income.

Inconsistent Profits

A high ROE might be misleading if a company has faced consecutive years of losses. This scenario can result in a temporarily inflated ROE due to the reduced denominator (shareholders' equity) after years of losses.

Excess Debt

Excessive borrowing can also boost ROE, but this may not reflect genuine performance or growth. Companies taking on significant debt to buy back their own stock can inflate earnings per share (EPS) without improving operational performance.

Negative Net Income

When net income and shareholders' equity turn negative, calculating ROE becomes inappropriate. This situation usually indicates excessive debt or inconsistent profitability.

Limitations of ROE

ROE has its limitations, particularly when comparing companies in different industries. Variations in operating margins and financing structures can make cross-sector ROE comparisons less meaningful. Therefore, it's crucial to complement ROE analysis with other financial metrics for a comprehensive evaluation of a company's financial health.


While ROE assesses profit generation relative to shareholders' equity, Return on Invested Capital (ROIC) goes further by considering all sources of capital, including debt. ROIC offers a more holistic view of a company's ability to make money.

Example of ROE

To illustrate the concept, let's compare the ROE figures for Alphabet, Amazon, and Apple based on their fiscal year 2022 results:

  • Alphabet: 23.62%
  • Amazon: -1.91%
  • Apple: 175.46%

These figures demonstrate how ROE can vary dramatically among industry leaders, reflecting differences in financial structures and performance.

Calculating ROE Using Excel

To calculate ROE in Excel, follow these steps:

  1. Set appropriate column widths for clarity.
  2. Enter the company names in cells B1 and C1.
  3. Label cells A2 and A3 as "Net Income" and "Shareholders' Equity," respectively.
  4. In cells B4 and C4, enter the formula for "Return on Equity": =B2/B3 and =C2/C3.
  5. Fill in the corresponding values for "Net Income" and "Shareholders' Equity" in cells B2, B3, C2, and C3.

ROE and DuPont Analysis

DuPont analysis breaks down ROE into its components, providing deeper insights into a company's performance. It considers net profit margin, asset turnover, and equity multiplier, offering a comprehensive view of what drives a company's ROE.

What Is a Good ROE?

A "good" ROE depends on the industry and competitors. Industries with high competition and substantial asset requirements tend to have lower ROE averages. Conversely, sectors with fewer players and lower asset demands may exhibit higher ROE averages.
