While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. We'll use ROE to examine Pennon Group Plc (LON:PNN), by way of a worked example.
ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. Put another way, it reveals the company's success at turning shareholder investments into profits.

How Is ROE Calculated?
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 Pennon Group is:
2.7% = UK£35m ÷ UK£1.3b (Based on the trailing twelve months to September 2021).
The 'return' is the amount earned after tax over the last twelve months. Another way to think of that is that for every £1 worth of equity, the company was able to earn £0.03 in profit.
Does Pennon Group 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. As is clear from the image below, Pennon Group has a lower ROE than the average (4.4%) in the Water Utilities industry.
Unfortunately, that's sub-optimal. That being said, a low ROE is not always a bad thing, especially if the company has low leverage as this still leaves room for improvement if the company were to take on more debt. A high debt company having a low ROE is a different story altogether and a risky investment in our books.

Why You Should Consider Debt When Looking At ROE
Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, or debt. 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 Pennon Group's Debt And Its 2.7% Return On Equity
Pennon Group does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.55. Its ROE is quite low, even with the use of significant debt; that's not a good result, in our opinion. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
