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. We'll use ROE to examine Endesa, S.A. (BME:ELE), by way of a worked example.
Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.
How Is ROE Calculated?
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Endesa is:
23% = €2.2b ÷ €9.2b (Based on the trailing twelve months to June 2025).
The 'return' is the amount earned after tax over the last twelve months. One way to conceptualize this is that for each €1 of shareholders' capital it has, the company made €0.23 in profit.

Does Endesa Have A Good ROE?
Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As you can see in the graphic below, Endesa has a higher ROE than the average (9.9%) in the Electric Utilities 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
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 case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the use of debt will improve the returns, but will not change the equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Endesa's Debt And Its 23% ROE
It's worth noting the high use of debt by Endesa, leading to its debt to equity ratio of 1.05. There's no doubt the ROE is impressive, but it's worth keeping in mind that the metric could have been lower if the company were to reduce its debt. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.
Summary
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. 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.
But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
