Key takeaways
  • Return on equity (ROE) is designed to measure how much profit a company may earn for every dollar that their shareholders have invested in them.

  • There is a basic ROE calculation as well as a more advanced calculation option, which is often referred to as the DuPont formula or DuPont analysis.

  • ROE may provide different insights when compared to other measures of profitability, such as return on assets (ROA) or return on invested capital (ROIC).

What is return on equity (ROE)?

Return on equity (ROE) can be one way for investors to measure how much profit a company earns for every dollar their shareholders invested in the company’s stock.

While some investors may find it helpful to understand ROE, other investors may also find it helpful to find the most competitive rates for personal savings. If that fits with your financial goals, Raisin’s marketplace lets you instantly compare competitive rates across multiple savings options.

The return on equity formula

The basic ROE calculation

The following is typically used as the basic calculation for ROE:

Net income / shareholder equity = ROE

Advanced calculation: The 3-Step DuPont analysis

The DuPont formula or analysis may offer a more advanced calculation for ROE. It involves multiple calculations and steps, as detailed below: 

  1. Net income / revenue = Net profit margin
  2. Sales / average total assets = Asset turnover (AT)
  3. Average total assets / average shareholder equity = Equity multiplier (EM) 
  4. Net profit margin x asset turnover x equity multiplier = DuPont analysis

What is a "good" return on equity?

There may not be a specific ROE number that an investor would universally consider to be “good” for every company. However, it may often be helpful to look at various benchmarks in order to compare companies. The following benchmarks may be helpful for investors looking into ROE:

S&P 500 benchmarks

Companies on the S&P 500 may see approximately 13% ROE on average.

Industry-specific norms

ROE may also vary according to the industry that a company operates in. For instance, companies in the United States whose primary operations don’t center on financial services may see approximately 11% ROE on average. 

Relative vs. absolute ROE

Generally speaking, relative ROE refers to the total gain or total loss of a stock. Absolute ROE generally compares the stock’s gain or loss to the performance of a benchmark, such as the S&P 500.

Limitations and "red flags" in ROE

The impact of high debt

ROE typically does not account for any debts a company may have. Generally, increasing the amount of debt can also decrease total shareholder equity. If a company has high levels of debt, or if they take on debt for share buybacks, that may make their ROE calculation appear higher.

Stock buybacks

When a company buys back its own shares, that generally reduces the available equity. In calculating ROE, that reduced amount of equity can make a company’s ROE appear to be higher.

Negative ROE

Negative ROE may mean that a company is experiencing a net loss. While each situation varies, this could signal the company may be going through financial issues or challenges. 

ROE vs. other profitability metrics

ROE vs. ROA (Return on assets)

Return on assets (ROA) calculates a company’s profit generation based on its total assets, including debt and equity. ROE calculations, on the other hand, do not typically account for debt.

H3: ROE vs. ROIC (Return on invested capital)

Return on invested capital (ROIC) measures how a company earns profits based on its utilization of its debt and equity. ROIC also typically involves a company’s net operating profit after taxes (NOPAT) while ROE focuses on a company’s net income.

Bottom line

Calculating a company’s ROE may provide insights into how well that company can generate a profit based on the equity provided by its shareholders. It may be a helpful tool for investors comparing stock investment options across companies.

Frequently asked questions

A high ROE may not include other important considerations, such as a company’s debt load.

A stock buyback may reduce a company’s equity while also raising its ROE.

Equity may increase or decrease, so using year-end equity only when calculating ROE may not provide the most accurate insights. Average equity may provide a more accurate calculation when used within ROE calculations.
