How Is ROE Calculated?

ROE 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 Woongjin is:

23% = ₩80b ÷ ₩353b (Based on the trailing twelve months to June 2025).

The 'return' is the profit over the last twelve months. Another way to think of that is that for every ₩1 worth of equity, the company was able to earn ₩0.23 in profit.

Does Woongjin Have A Good Return On Equity?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As you can see in the graphic below, Woongjin has a higher ROE than the average (6.5%) in the Industrials industry.

That's clearly a positive. With that said, a high ROE doesn't always indicate high profitability. A higher proportion of debt in a company's capital structure may also result in a high ROE, where the high debt levels could be a huge risk .

The Importance Of Debt To 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 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Combining Woongjin's Debt And Its 23% Return On Equity

It appears that Woongjin makes extensive use of debt to improve its returns, because it has an alarmingly high debt to equity ratio of 3.63. Its ROE is pretty good, but given the impact of the debt, we're less than enthused, overall.

Summary

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. All else being equal, a higher ROE is better.

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.
