How To 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 Wooshin Systems is:

9.9% = ₩10b ÷ ₩104b (Based on the trailing twelve months to June 2024).

The 'return' refers to a company's earnings over the last year. One way to conceptualize this is that for each ₩1 of shareholders' capital it has, the company made ₩0.10 in profit.

Does Wooshin Systems Have A Good Return On Equity?

By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. You can see in the graphic below that Wooshin Systems has an ROE that is fairly close to the average for the Auto Components industry (8.5%).

That's neither particularly good, nor bad. Although the ROE is similar to the industry, we should still perform further checks to see if the company's ROE is being boosted by high debt levels. If a company takes on too much debt, it is at higher risk of defaulting on interest payments.

How Does Debt Impact Return On Equity?

Virtually all companies need money to invest in the business, to grow profits. That cash can come from retained earnings, issuing new shares (equity), 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.

Wooshin Systems' Debt And Its 9.9% ROE

Wooshin Systems clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.74. Its ROE is quite low, even with the use of significant debt; that's not a good result, in our opinion. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.

Summary

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 the same ROE, then I would generally prefer the one with less debt.

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. 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.
