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 Severn Trent PLC (LON:SVT).
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 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 Severn Trent is:
13% = UK£230m ÷ UK£1.8b (Based on the trailing twelve months to September 2024).
The 'return' is the amount earned after tax over the last twelve months. That means that for every £1 worth of shareholders' equity, the company generated £0.13 in profit.

Does Severn Trent Have A Good ROE?
Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As you can see in the graphic below, Severn Trent has a higher ROE than the average (3.9%) in the Water Utilities industry.
That's clearly a positive. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. A higher proportion of debt in a company's capital structure may also result in a high ROE, where the high debt levels could be a huge risk . Our risks dashboardshould have the 2 risks we have identified for Severn Trent.
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 required for growth will boost returns, but will not impact the shareholders' equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Combining Severn Trent's Debt And Its 13% Return On Equity
It appears that Severn Trent makes extensive use of debt to improve its returns, because it has an alarmingly high debt to equity ratio of 4.78. Its ROE is decent, but once I consider all the debt, I'm not really impressed.
Conclusion
Return on equity is useful for comparing the quality of different businesses. A company that can achieve a high return on equity without debt could be considered a high quality business. All else being equal, a higher ROE is better.
Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
