One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. To keep the lesson grounded in practicality, we'll use ROE to better understand SkyWest, Inc. (NASDAQ:SKYW).

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 To 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 SkyWest is:

7.9% = US$177m ÷ US$2.2b (Based on the trailing twelve months to June 2024).

The 'return' is the income the business earned over the last year. That means that for every $1 worth of shareholders' equity, the company generated $0.08 in profit.

Does SkyWest 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. You can see in the graphic below that SkyWest has an ROE that is fairly close to the average for the Airlines industry (9.2%).

So while the ROE is not exceptional, at least its acceptable. 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 true, then it is more an indication of risk than the potential.

How Does Debt Impact ROE?

Most companies need money -- from somewhere -- to grow their profits. That cash can come from retained earnings, issuing new shares (equity), 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

SkyWest's Debt And Its 7.9% ROE

SkyWest does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.25. With a fairly low ROE, and significant use of debt, it's hard to get excited about this business at the moment. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.

Conclusion

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. 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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
