What is Return on Equity (ROE)?
ROE is important in evaluating a company’s financial performance because it gives investors and analysts an indication of how well the company is using its capital and whether or not it is generating enough returns to justify its investors’ investments.
ROE also plays an important role in financial ratio analysis. A comparison of a company's ROE to those of other companies within its industry can provide insight into how well that company is performing in terms of generating profits from its investments.
How to Calculate ROE?
There are two ways to calculate ROE: the basic formula and the extended formula.The basic formula
The basic formula for ROE is:ROE = Net Income / Shareholders' Equity
Net income is the amount of income that a company earns after deducting all expenses, taxes, and dividends. It can be found on the income statement of a company.
Shareholders' equity is the amount of money that belongs to the shareholders after subtracting all liabilities from all assets. It can be found on the balance sheet of a company.
For example, suppose Company A has a net income of $10 million and a shareholders' equity of $50 million. Then, its ROE is:
ROE = 10 / 50 = 0.2 or 20%
This means that Company A earns $0.2 of net income for every dollar of shareholders' equity.
The extended formula
The extended formula for ROE is:ROE = Net Profit Margin x Asset Turnover x Equity Multiplier
where:
- Net profit margin is the ratio of net income to revenue. It measures how much of each dollar of revenue is left as net income after paying all expenses.
- Asset turnover is the ratio of revenue to total assets. It measures how efficiently a company uses its assets to generate revenue.
- Equity multiplier is the ratio of total assets to shareholders' equity. It measures how much leverage a company uses to finance its assets.
The extended formula breaks down ROE into three components that reflect different aspects of a company's performance: operating efficiency, asset use efficiency, and financial leverage.
For example, suppose Company B has a net income of $15 million, revenue of $100 million, total assets of $200 million, and shareholders' equity of $100 million. Then, its ROE can be calculated as:
Net profit margin = 15 / 100 = 0.15 or 15%
Asset turnover = 100 / 200 = 0.5 or 50%
Equity multiplier = 200 / 100 = 2
ROE = 0.15 x 0.5 x 2 = 0.15 or 15%
This means that Company B earns $0.15 of net income for every dollar of shareholders' equity.
Comparing ROE Across Companies
Case Study: Comparing ROE Across Companies in the Same Industry
ROE of Walmart, Target, and Costco
- Walmart: 20.5%
- Target: 29.8%
- Costco: 22.4%
Factors that Affect ROE
- Net profit margin: It analyzes how much of every dollar of revenue remains as a profit after all costs have been paid. This ratio is known as net income to revenue. When all else is equal, a larger net profit margin results in a higher ROE.
- Asset turnover: This measure of how effectively a business uses its assets to create income is the ratio of revenue to total assets. If everything else is equal, a higher asset turnover will result in a higher ROE.
- Equity multiplier: It gauges how much leverage a company employs to fund its assets and is expressed as the ratio of total assets to shareholders' equity. If all else is equal, a greater equity multiplier will result in a higher ROE.
- Walmart: 20.5% = 3.1% x 2.2 x 3.0
- Target: 29.8% = 6.3% x 1.9 x 2.5
- Costco: 22.4% = 2.4% x 3.6 x 2.6
Analysis of ROE Components
- Net profit margin: Target has the strongest operating efficiency and cost control among the three businesses, as seen by its largest net profit margin. Costco has the lowest net profit margin, meaning that the business runs on very narrow margins and depends heavily on high sales volume to make money.
- Asset turnover: Costco has the best asset usage and inventory management among the three businesses since it has the biggest asset turnover. Walmart has the lowest asset turnover, which indicates that a lot of its assets are lying around or being used inefficiently.
- Equity multiplier: Walmart employs more debt than equity to finance its assets since it has the biggest equity multiplier of the three businesses. Its financial risk rises as a result, but its returns on equity are also amplified. Costco has the lowest equity multiplier, which indicates that it finances its assets mostly through stock rather than debt. Although this decreases its financial risk, it also results in poorer returns on equity.
Best Practices for Using ROE to Compare Companies
So how can you use ROE effectively to compare companies? Here are some best practices to keep in mind:- Combine ROE with other metrics and ratios. ROE is not a reliable predictor of a company's worth or quality on its own. It must be combined with other metrics like debt-to-equity ratio, valuation multiples, profit margin, revenue growth, and growth in earnings, revenues, and profit margin. These measurements can give a clearer view of the financial health and growth prospects of a company.
- Compare ROE across the same sector or industry. Capital intensity and profitability vary across various industries and sectors. For instance, because they have fewer capital requirements and larger profit margins than utility businesses, technology companies typically have higher ROEs. As a result, comparing ROE between businesses in the same industry or sector is more insightful than doing so between different ones.
- Compare ROE over time. Changes in net income, shareholders' equity, or both might affect ROE year over year. The ROE for a single year could not be indicative of a company's long-term success or trend. In order to find consistency or growth over time, it is, therefore, preferable to compare ROE over a number of years or quarters. A business that can sustain or grow its ROE over time may have a solid growth strategy or a lasting competitive advantage.
- Adjust ROE for non-recurring items. Sometimes one-time or irregular factors, such as asset sales, write-offs, restructuring costs, tax advantages, or litigation settlements, can have an impact on a company's net income or shareholders' equity. Several factors might skew a company's real profitability or capital structure, making its ROE inaccurate or unrelatable. As a result, it is wise to adjust ROE for these one-time expenses and utilize the adjusted ROE for comparison.
- Understand the drivers of ROE. Three elements can be separated out of ROE: profit margin, asset turnover, and financial leverage. The amount of each dollar of revenue that is transformed into net income is known as the profit margin. Asset turnover gauges how effectively a business generates revenue from its assets. Financial leverage quantifies the ratio of a company's debt to equity. You can calculate a company's ROE by adding these three elements together.
FAQ
Return on Equity, or ROE, is a metric that expresses how well a business turns a company's equity into profits. Net income is divided by shareholders' equity to arrive at this figure. A greater ROE indicates more profitability and efficiency in the company's use of equity capital.
ROE can be broken down into three components using the DuPont analysis, which multiplies the net profit margin, the asset turnover, and the equity multiplier. The asset turnover metric gauges how well the business uses its assets to create sales, the equity multiplier indicates how much leverage the business employs to finance its assets, and the net profit margin indicates how much of each dollar of sales is left as net income.
The business cycle, the capital structure, the dividend policy, the industry or sector in which the firm works, and the accounting practices are a few variables that can impact ROE. ROE may vary among companies or sectors due to variations in profitability, risk, and growth potential. The business cycle can also have an impact on ROE since, depending on the state of the economy, companies may see increases in or decreases in earnings.
The capital structure can also impact return on equity (ROE); utilizing more debt raises the equity multiplier but also raises interest costs and financial risk. In the same way that various techniques of depreciation, inventory value, or revenue recognition can affect net income and shareholders' equity, so too can accounting policies impact return on equity.

Checklist for applying ROE: The Key to Comparing Company Performance

Another limitation is comparability. Two situations may use the same term while relying on different assumptions. Before comparing them, check whether the time period, measurement method, legal setting, or business model is similar enough for the comparison to be meaningful.
