Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). To keep the lesson grounded in practicality, we’ll use ROE to better understand Aqua America, Inc. (NYSE:WTR).
Over the last twelve months Aqua America has recorded a ROE of 12%. Another way to think of that is that for every $1 worth of equity in the company, it was able to earn $0.12.

How Do I Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for Aqua America:
12% = 249.118 ÷ US$2.0b (Based on the trailing twelve months to September 2018.)
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. Shareholders’ equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.
What Does Return On Equity Mean?
ROE measures a company’s profitability against the profit it retains, and any outside investments. The ‘return’ is the profit over the last twelve months. A higher profit will lead to a higher ROE. So, all else equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.
Does Aqua America Have A Good ROE?
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. As is clear from the image below, Aqua America has a better ROE than the average (9.2%) in the Water Utilities industry.
That’s what I like to see. We think a high ROE, alone, is usually enough to justify further research into a company. For example, I often check if insiders have been buying shares .
How Does Debt Impact Return On Equity?
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 and second cases, the ROE will reflect this use of cash for investment in the business. 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.
