ROE % measures the rate of return on the ownership interest (shareholder's equity) of the common stock owners. It measures a firm's efficiency at generating profits from every unit of shareholders' equity (also known as net assets or assets minus liabilities). ROE % shows how well a company uses investment funds to generate earnings growth. ROE %s between 15% and 20% are considered desirable.
The factors that affect a company's ROE % can be illustrated with the three-step DuPont Analysis:
Note:
The net income data used here is four times the quarterly (Mar. 2026) net income data. The Revenue data used here is four times the quarterly (Mar. 2026) revenue data. The same rule applies to Pre-Tax Income and Operating Income.
* In the five-step DuPont Analysis, Operating Income is only available for non-financial companies. Thus, for Insurance companies, we use EBIT as a substitution of Operating Income. For Banks, both Operating Income and EBIT is unavailable. Thus we combined Interest Burden and Operating Margin % into Pretax Margin %, and the DuPont Analysis is divided into four components instead.

Like ROA %, ROE % is calculated with only 12 months data. Fluctuations in company's earnings or business cycles can affect the ratio drastically. It is important to look at the ratio from a long term perspective.
Asset light businesses require very few assets to generate very high earnings. Their ROE %s can be extremely high.
