How Do You Calculate Return On Equity?

Return on equity 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 Supreme Electronics is:

15% = NT$3.0b ÷ NT$19b (Based on the trailing twelve months to September 2024).

The 'return' refers to a company's earnings over the last year. That means that for every NT$1 worth of shareholders' equity, the company generated NT$0.15 in profit.

Does Supreme Electronics 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. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. Pleasingly, Supreme Electronics has a superior ROE than the average (8.9%) in the Electronic industry.

That's what we like to see. Bear in mind, a high ROE doesn't always mean superior financial performance. 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 .

Why You Should Consider Debt When Looking At ROE

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 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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Supreme Electronics' Debt And Its 15% ROE

Supreme Electronics clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.86. While its ROE is pretty respectable, the amount of debt the company is carrying currently is not ideal. 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 useful for comparing the quality of different businesses. Companies that can achieve high returns on equity without too much debt are generally of good quality. All else being equal, a higher ROE is better.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. 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.
