ROE (Return on Equity) measures how efficiently a company generates profit using the equity capital provided by its shareholders.
ROE (%) = Net Income ÷ Shareholders' Equity × 100
What it measures
ROE shows how well a company turns its equity capital into profit. For the same amount of profit, a company using less equity capital will show a higher ROE.
How to read it
Increasing debt relative to equity can raise ROE even if underlying profitability has not changed, so it is worth checking financial leverage as well.
ROE can also spike due to one-off extraordinary gains, so looking at the trend over several years can be more informative than a single year's figure.
What counts as an appropriate ROE level varies by industry.

Frequently Asked Questions
Is a higher ROE always better?
A high ROE is often seen as efficient use of shareholders' equity, but ROE also rises when a company takes on more debt, so a high ROE alone does not indicate financial soundness. It is worth checking alongside metrics such as the equity ratio.
What is a typical ROE level?
Appropriate levels vary by industry, but a figure around 8% is sometimes cited as a rough benchmark for the Japanese market. This is only a general reference and does not guarantee anything about any individual company.
Does a 15% ROE mean a company is excellent?
A 15% ROE is above the commonly cited benchmark of roughly 8%, but that alone does not make a company "excellent." It is also worth checking debt levels, the sustainability of profits, and industry characteristics. Companies with high ROE are sometimes characterized by capital-efficient management (such as share buybacks) or business models that generate large profits with relatively little capital.
