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 Nousbo Co., Ltd. (KOSDAQ:332290).
Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.
How Is ROE Calculated?
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Nousbo is:
5.8% = ₩1.5b ÷ ₩27b (Based on the trailing twelve months to June 2025).
The 'return' is the profit over the last twelve months. One way to conceptualize this is that for each ₩1 of shareholders' capital it has, the company made ₩0.06 in profit.

Does Nousbo Have A Good ROE?
By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. The image below shows that Nousbo has an ROE that is roughly in line with the Chemicals industry average (6.1%).
That's neither particularly good, nor bad. Even if the ROE is respectable when compared to the industry, its worth checking if the firm's ROE is being aided by high debt levels. If so, this increases its exposure to financial risk. You can see the 3 risks we have identified for Nousbo by visiting our risks dashboard for free on our platform here.
How Does Debt Impact Return On Equity?
Virtually all companies need money to invest in the business, to grow profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. 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.
Nousbo's Debt And Its 5.8% ROE
Nousbo does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.25. Its ROE is quite low, even with the use of significant debt; that's not a good result, in our opinion. 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. Companies that can achieve high returns on equity without too much debt are generally of good quality. If two companies have the same ROE, then I would generally prefer the one with less debt.
But when a business is high quality, the market often bids it up to a price that reflects this. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider. So I think it may be worth checking this free this detailed graph of past earnings, revenue and cash flow.
