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 Acciona, S.A. (BME:ANA), by way of a worked example.
Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. Simply put, it is used to assess the profitability of a company in relation to its equity capital.
How Is ROE Calculated?
The formula for return on equity is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Acciona is:
18% = €1.1b ÷ €6.0b (Based on the trailing twelve months to June 2025).
The 'return' refers to a company's earnings over the last year. Another way to think of that is that for every €1 worth of equity, the company was able to earn €0.18 in profit.

Does Acciona Have A Good ROE?
One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. Pleasingly, Acciona has a superior ROE than the average (9.4%) in the Electric Utilities industry.
That's what we like to see. With that said, a high ROE doesn't always indicate high profitability. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk.

How Does Debt Impact ROE?
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 use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.
Combining Acciona's Debt And Its 18% Return On Equity
It's worth noting the high use of debt by Acciona, leading to its debt to equity ratio of 2.05. There's no doubt its ROE is decent, but the very high debt the company carries is not too exciting to see. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
Conclusion
Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. 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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
