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 Waste Management, Inc. (NYSE:WM), by way of a worked example.
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. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How To Calculate Return On Equity?
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 Waste Management is:
34% = US$2.7b ÷ US$8.0b (Based on the trailing twelve months to December 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 $0.34 in profit.
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. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. Pleasingly, Waste Management has a superior ROE than the average (13%) in the Commercial Services industry.
That's what we like to see. 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.

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 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.
Waste Management's Debt And Its 34% ROE
It's worth noting the high use of debt by Waste Management, leading to its debt to equity ratio of 2.09. 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. 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.
