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 Automatic Data Processing, Inc. (NASDAQ:ADP).

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 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 Automatic Data Processing is:

72% = US$3.8b ÷ US$5.3b (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 $1 worth of shareholders' equity, the company generated $0.72 in profit.

Does Automatic Data Processing 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, Automatic Data Processing has a higher ROE than the average (20%) in the Professional Services industry.

That is a good sign. With that said, a high ROE doesn't always indicate high profitability. Aside from changes in net income, a high ROE can also be the outcome of high debt relative to equity, which indicates risk.

The Importance Of Debt To Return On Equity

Companies usually need to invest money to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the first two cases, the ROE will capture this use of capital to grow. 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.

Automatic Data Processing's Debt And Its 72% ROE

It's worth noting the high use of debt by Automatic Data Processing, leading to its debt to equity ratio of 1.69. There's no doubt the ROE is impressive, but it's worth keeping in mind that the metric could have been lower if the company were to reduce its debt. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.
