While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. To keep the lesson grounded in practicality, we'll use ROE to better understand Kawasaki Heavy Industries, Ltd. (TSE:7012).
Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.
Return on equity can be calculated by using the formula:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Kawasaki Heavy Industries is:
12% = JP¥100b ÷ JP¥824b (Based on the trailing twelve months to September 2025).
The 'return' is the income the business earned over the last year. Another way to think of that is that for every ¥1 worth of equity, the company was able to earn ¥0.12 in profit.

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. Pleasingly, Kawasaki Heavy Industries has a superior ROE than the average (7.7%) in the Machinery industry.
That is a good sign. Bear in mind, a high ROE doesn't always mean superior financial performance. Aside from changes in net income, a high ROE can also be the outcome of high debt relative to equity, which indicates risk.

Virtually all companies need money to invest in the business, to grow profits. That cash can come from issuing shares, retained earnings, or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.
Kawasaki Heavy Industries clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.07. There's no doubt its ROE is decent, but the very high debt the company carries is not too exciting to see. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
Return on equity is useful for comparing the quality of different businesses. In our books, the highest quality companies have high return on equity, despite low debt. If two companies have around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.
But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
