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. We'll use ROE to examine Alarm.com Holdings, Inc. (NASDAQ:ALRM), by way of a worked example.

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

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 Alarm.com Holdings is:

17% = US$124m ÷ US$731m (Based on the trailing twelve months to September 2024).

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 $0.17 in profit.

Does Alarm.com Holdings Have A Good Return On Equity?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As is clear from the image below, Alarm.com Holdings has a better ROE than the average (12%) in the Software industry.

That is a good sign. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk.

How Does Debt Impact 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 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.

Alarm.com Holdings' Debt And Its 17% ROE

It's worth noting the high use of debt by Alarm.com Holdings, leading to its debt to equity ratio of 1.34. While its ROE is respectable, it is worth keeping in mind that there is usually a limit as to how much debt a company can use. 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 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 ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. 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. So I think it may be worth checking this free report on analyst forecasts for the company.
