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). We'll use ROE to examine The York Water Company (NASDAQ:YORW), by way of a worked example.
Over the last twelve months York Water has recorded a ROE of 11%. One way to conceptualize this, is that for each $1 of shareholders' equity it has, the company made $0.11 in profit.

How Do You Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for York Water:
11% = US$14m ÷ US$127m (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 the capital paid in by shareholders, plus any retained earnings. 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 Signify?
ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the amount earned after tax over the last twelve months. The higher the ROE, the more profit the company is making. So, all else being equal, a high ROE is better than a low one. Clearly, then, one can use ROE to compare different companies.
Does York Water 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. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. Pleasingly, York Water has a superior ROE than the average (8.3%) company in the Water Utilities industry.
That's clearly a positive. We think a high ROE, alone, is usually enough to justify further research into a company. For example you might check if insiders are buying shares.
The Importance Of Debt To Return On Equity
Companies usually need to invest money to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. 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 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.
