Companies rely on capital from many sources to grow, operate, and create value. For shareholders, the key question is whether that capital is being used effectively to generate profit.
Return on equity (ROE) helps answer that question. By comparing net income with shareholders’ equity, ROE shows how efficiently a company turns equity capital into earnings. Finance leaders can use the ratio to assess financial health and better understand how profitability and capital structure shape results.
Because ROE can rise or fall for different reasons, it’s most useful when viewed in context. Knowing how to calculate return on equity—and what drives the ratio—helps finance teams evaluate performance with greater clarity.

What Is Return on Equity?
Return on equity is a profitability ratio that measures how much net income a company generates relative to shareholders' equity. It is typically expressed as a percentage. As a general benchmark, an ROE of 15% to 20% is typically considered a good return on equity, though acceptable ranges vary significantly by industry.
The two main components for calculating ROE are:
Net income: The profit remaining after expenses, interest, and taxes have been deducted from revenue.
Shareholders' equity: The residual value belonging to shareholders after the company's liabilities are subtracted from its assets.
Together, these figures show how effectively a company is generating earnings from the capital shareholders have invested and retained in the business. A higher ROE generally indicates that a company is generating more profit for each dollar of equity.
However, a high ratio does not automatically indicate stronger financial performance. Debt levels, changes in equity, and one-time gains or losses can all influence the result.
How to Calculate Return on Equity
The standard return on equity formula is:
Return on Equity = Net Income ÷ Average Shareholders' Equity × 100
Net income can typically be found on the income statement, while shareholders' equity appears on the balance sheet. Because net income reflects performance over a period while equity is measured at a point in time, using average shareholders' equity can provide a more representative comparison.
Follow these four steps to calculate return on equity:
1. Determine Net Income
Locate the company's net income for the period being analyzed. Net income represents the profit remaining after operating expenses, interest, taxes, and other applicable costs have been deducted.
If the company issues preferred shares, adjust your calculation:
Net Income: Use Net Income minus Preferred Dividends.
Equity: Use Common Shareholders' Equity (exclude preferred stock).
2. Calculate Average Shareholders' Equity
Determine shareholders' equity at the beginning and end of the reporting period. Then calculate the average:
Average Shareholders' Equity =
(Beginning Shareholders' Equity + Ending Shareholders' Equity) ÷ 2
For example, if a company began the year with $8 million in shareholders' equity and ended with $12 million:
($8 million + $12 million) ÷ 2 = $10 million
The company's average shareholders' equity for the period is $10 million.
3. Divide Net Income by Average Shareholders' Equity
Apply the ROE formula using net income for the same reporting period.
Consider a company with:
$2 million in net income
$10 million in average shareholders' equity
The calculation would be:
$2 million ÷ $10 million = 0.20
The company generated 20 cents of net income for every dollar of average shareholders' equity.
4. Convert the Result to a Percentage
Multiply the result by 100 to express ROE as a percentage:
0.20 × 100 = 20%
The company's return on equity is 20%. This means it generated the equivalent of 20% of its average shareholders' equity in net income during the period.
Tracking the ratio across multiple reporting periods can help finance leaders determine whether the company's ability to generate returns from equity is strengthening or weakening.
Return on assets evaluates overall asset efficiency; return on equity measures returns specifically generated on shareholder capital.
Why Is Return on Equity Important?
ROE connects profitability with the capital used to generate it. A company may increase net income from one year to the next, but that increase provides only part of the picture if its equity base has also changed substantially.
Monitoring return on equity can help finance teams:
Evaluate how efficiently shareholder capital generates profit
Track changes in financial performance over time
Compare performance with relevant industry peers
Understand how capital structure affects shareholder returns
Assess the effects of retained earnings and shareholder distributions
Support capital allocation and investment decisions
ROE can also help leaders investigate the factors behind changes in performance. An improving ratio may reflect stronger profitability or more efficient use of capital, while a declining ratio may point to lower earnings or a growing equity base that has yet to generate proportional returns.
Like most financial ratios, ROE is most useful when evaluated alongside other measures and within the context of the company's industry, strategy, and capital structure.
Return on Equity vs. Return on Assets
Return on equity and return on assets (ROA) both measure how effectively a company generates profit, but they evaluate that performance against different parts of the balance sheet.
ROE measures net income relative to shareholders' equity:
ROE = Net Income ÷ Average Shareholders' Equity × 100
Return on assets, or ROA, measures net income relative to the company's assets:
ROA = Net Income ÷ Average Total Assets × 100
The distinction matters because companies can finance assets with both debt and equity. Return on assets provides a broader view of how efficiently the company uses its asset base, while return on equity focuses specifically on the return generated relative to shareholder capital.
Looking at both measures can also provide insight into the role leverage plays in financial performance. A company with significant debt may have a much higher ROE than ROA because its equity represents a smaller portion of the capital used to fund its assets.
How to Interpret Return on Equity
A higher ROE generally means a company is generating more profit from its equity base. But the percentage alone doesn’t tell leaders whether performance is strong or improving.
To interpret ROE, start with context. Compare it against companies with similar business models, capital needs, and financial structures. A software company and a manufacturer may have very different equity requirements, so their ROE figures are not always meaningful side by side.
Then look at the trend over time. Is ROE rising, falling, or staying consistent? A change in the ratio should prompt finance leaders to look beneath the headline number and understand what changed in the business.
That context helps determine whether ROE reflects stronger performance, a temporary fluctuation, or a change in how the company is financed.
What Factors Affect Return on Equity?
ROE reflects several aspects of financial performance at once. Breaking the ratio into its underlying drivers can provide a clearer picture of why it is changing.
One common approach is the DuPont analysis, which separates ROE into three components:
ROE = Net Profit Margin × Asset Turnover × Equity Multiplier
Each component in the DuPont formula represents a different driver of shareholder returns:
Net profit margin shows how much profit the company generates from its revenue.
Asset turnover measures how efficiently assets are used to generate revenue.
Equity multiplier reflects the extent to which assets are financed with equity versus debt.
This analysis can help finance leaders determine whether ROE is being driven primarily by profitability, operating efficiency, or financial leverage.
For example, two companies may report the same ROE even though one achieves it through stronger profit margins and the other relies more heavily on debt. Looking beneath the headline ratio provides a more complete picture of how those returns are being generated.
Return on equity should be treated as a starting point, not a final answer.
Use ROE to Understand Financial Performance
ROE is most valuable when it helps finance leaders ask better questions about performance. A rising ratio may point to stronger earnings, but it may also reflect changes in the equity base. A lower ratio may signal pressure on profitability, or it may reflect investment that has not yet produced returns.
That is why ROE should be treated as a starting point, not a final answer. When finance teams understand what is driving the ratio, they can better evaluate how efficiently the business is using shareholder capital and whether today’s decisions are creating stronger potential for future returns.
