How To Calculate Return On Equity?

Return on equity 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 United Utilities Group is:

3.9% = UK£110m ÷ UK£2.8b (Based on the trailing twelve months to September 2020).

The 'return' is the income the business earned over the last year. That means that for every £1 worth of shareholders' equity, the company generated £0.04 in profit.

Does United Utilities Group Have A Good ROE?

By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As shown in the graphic below, United Utilities Group has a lower ROE than the average (6.2%) in the Water Utilities industry classification.

Unfortunately, that's sub-optimal. Although, we think that a lower ROE could still mean that a company has the opportunity to better its returns with the use of leverage, provided its existing debt levels are low. When a company has low ROE but high debt levels, we would be cautious as the risk involved is too high.

Why You Should Consider Debt When Looking At ROE

Virtually all companies need money to invest in the business, to grow 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Combining United Utilities Group's Debt And Its 3.9% Return On Equity

It seems that United Utilities Group uses a huge volume of debt to fund the business, since it has an extremely high debt to equity ratio of 3.14. We consider it to be a negative sign when a company has a rather low ROE despite a rather high debt to equity.

Summary

Return on equity is useful for comparing the quality of different businesses. In our books, the highest quality companies have high return on equity, despite low debt. All else being equal, a higher ROE is better.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. 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.
