While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. To keep the lesson grounded in practicality, we'll use ROE to better understand Alarm.com Holdings, Inc. (NASDAQ:ALRM).

Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. Put another way, it reveals the company's success at turning shareholder investments into profits.

How Is ROE Calculated?

ROE 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:

16% = US$106m ÷ US$683m (Based on the trailing twelve months to June 2024).

The 'return' is the amount earned after tax over the last twelve months. That means that for every $1 worth of shareholders' equity, the company generated $0.16 in profit.

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

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. 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 Alarm.com Holdings has an ROE that is fairly close to the average for the Software industry (14%).

So while the ROE is not exceptional, at least its acceptable. Even if the ROE is respectable when compared to the industry, its worth checking if the firm's ROE is being aided by high debt levels. If so, this increases its exposure to financial risk.

Why You Should Consider Debt When Looking At 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 first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. That will make the ROE look better than if no debt was used.

Alarm.com Holdings' Debt And Its 16% ROE

Alarm.com Holdings does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.43. While its ROE is pretty respectable, the amount of debt the company is carrying currently is not ideal. 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.
