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. To keep the lesson grounded in practicality, we'll use ROE to better understand Energiekontor AG (ETR:EKT).

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. 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 Energiekontor is:

45% = €83m ÷ €186m (Based on the trailing twelve months to December 2023).

The 'return' is the profit over the last twelve months. One way to conceptualize this is that for each €1 of shareholders' capital it has, the company made €0.45 in profit.

Does Energiekontor Have A Good Return On Equity?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As you can see in the graphic below, Energiekontor has a higher ROE than the average (14%) in the Electrical industry.

That is a good sign. 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 .

The Importance Of Debt To Return On Equity

Companies usually need to invest money to grow their profits. That cash can come from retained earnings, issuing new shares (equity), 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. That will make the ROE look better than if no debt was used.

Energiekontor's Debt And Its 45% ROE

Energiekontor clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.67. Its ROE is pretty impressive but, it would have probably been lower without the use of debt. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.

Conclusion

Return on equity is one way we can compare its business quality of different companies. Companies that can achieve high returns on equity without too much debt are generally of good quality. If two companies have around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.
