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. By way of learning-by-doing, we'll look at ROE to gain a better understanding of Waste Management, Inc. (NYSE:WM).

Waste Management has a ROE of 29%, based on the last twelve months. One way to conceptualize this, is that for each $1 of shareholders' equity it has, the company made $0.29 in profit.

How Do I Calculate ROE?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for Waste Management:

29% = US$1.9b ÷ US$6.4b (Based on the trailing twelve months to March 2019.)

It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. It is all the money paid into the company from shareholders, plus any earnings retained. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.

What Does Return On Equity Signify?

ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the yearly profit. That means that the higher the ROE, the more profitable the company is. So, as a general rule, a high ROE is a good thing. Clearly, then, one can use ROE to compare different companies.

Does Waste Management Have A Good ROE?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. 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, Waste Management has a higher ROE than the average (13%) in the Commercial Services industry.

That's what I like to see. In my book, a high ROE almost always warrants a closer look. For example, I often check if insiders have been buying shares .

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 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.

Combining Waste Management's Debt And Its 29% Return On Equity

It's worth noting the significant use of debt by Waste Management, leading to its debt to equity ratio of 1.68. While the ROE is impressive, that metric has clearly benefited from the company's use of debt. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.

In Summary

Return on equity is useful for comparing the quality of different businesses. 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.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward. So I think it may be worth checking this free report on analyst forecasts for the company.
