One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. To keep the lesson grounded in practicality, we'll use ROE to better understand J Frontier Co.,Ltd. (TSE:2934).
Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. Put another way, it reveals the company's success at turning shareholder investments into profits.
How Do You Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for J FrontierLtd is:
5.4% = JP¥107m ÷ JP¥2.0b (Based on the trailing twelve months to August 2025).
The 'return' is the income the business earned over the last year. That means that for every ¥1 worth of shareholders' equity, the company generated ¥0.05 in profit.

Does J FrontierLtd Have A Good ROE?
One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As shown in the graphic below, J FrontierLtd has a lower ROE than the average (10%) in the Healthcare industry classification.
Unfortunately, that's sub-optimal. Although, we think that a lower ROE could still mean that a company has the opportunity to better its returns with the use of leverage, provided its existing debt levels are low. When a company has low ROE but high debt levels, we would be cautious as the risk involved is too high.

The Importance Of Debt To Return On Equity
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 case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the use of debt will improve the returns, but will not change the equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
J FrontierLtd's Debt And Its 5.4% ROE
J FrontierLtd does use a high amount of debt to increase returns. It has a debt to equity ratio of 2.03. The combination of a rather low ROE and significant use of debt is not particularly appealing. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
Conclusion
Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. 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.
Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
