How Is ROE Calculated?

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 United Airlines Holdings is:

29% = US$3.7b ÷ US$13b (Based on the trailing twelve months to March 2025).

The 'return' is the yearly profit. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.29 in profit.

Does United Airlines Holdings 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. 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, United Airlines Holdings has a higher ROE than the average (12%) in the Airlines industry.

That's what we like to see. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. 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. That cash can come from issuing shares, retained earnings, or debt. In the case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. That will make the ROE look better than if no debt was used.

United Airlines Holdings' Debt And Its 29% ROE

It's worth noting the high use of debt by United Airlines Holdings, leading to its debt to equity ratio of 2.19. Its ROE is pretty impressive but, it would have probably been lower without the use of debt. 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 a useful indicator of the ability of a business to generate profits and return them to shareholders. 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. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
