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. We'll use ROE to examine Open House Group Co., Ltd. (TSE:3288), by way of a worked example.
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. Put another way, it reveals the company's success at turning shareholder investments into profits.
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Open House Group is:
19% = JP¥104b ÷ JP¥539b (Based on the trailing twelve months to September 2025).
The 'return' is the yearly profit. One way to conceptualize this is that for each ¥1 of shareholders' capital it has, the company made ¥0.19 in profit.

By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As is clear from the image below, Open House Group has a better ROE than the average (8.3%) in the Consumer Durables industry.
That's clearly a positive. 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.
Companies usually need to invest money to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. That will make the ROE look better than if no debt was used.
Open House Group does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.34. While its ROE is respectable, it is worth keeping in mind that there is usually a limit as to how much debt a company can use. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.
Return on equity is useful for comparing the quality of different businesses. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have the same ROE, then I would generally prefer the one with less debt.
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.
