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. To keep the lesson grounded in practicality, we'll use ROE to better understand Waste Management, Inc. (NYSE:WM).
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?
The formula for return on equity is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Waste Management is:
33% = US$2.7b ÷ US$8.3b (Based on the trailing twelve months to December 2024).
The 'return' is the profit over the last twelve months. One way to conceptualize this is that for each $1 of shareholders' capital it has, the company made $0.33 in profit.

Does Waste Management 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. Pleasingly, Waste Management has a superior ROE than the average (12%) 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. Our risks dashboard should have the 2 risks we have identified for Waste Management.
Why You Should Consider Debt When Looking At ROE
Virtually all companies need money to invest in the business, to grow profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. 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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
Combining Waste Management's Debt And Its 33% Return On Equity
It's worth noting the high use of debt by Waste Management, leading to its debt to equity ratio of 2.84. Its ROE is pretty impressive but, it would have probably been lower without the use of debt. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.
