How Do You Calculate Return On Equity?

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 Aeroports de Paris is:

19% = €1.0b ÷ €5.4b (Based on the trailing twelve months to June 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 €0.19 in profit.

Does Aeroports de Paris 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. 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, Aeroports de Paris has a higher ROE than the average (14%) in the Infrastructure industry.

That's clearly a positive. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. Aside from changes in net income, a high ROE can also be the outcome of high debt relative to equity, which indicates risk. Our risks dashboardshould have the 2 risks we have identified for Aeroports de Paris.

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 case of the first and second options, the ROE will reflect this use of cash, for growth. 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 Aeroports de Paris' Debt And Its 19% Return On Equity

Aeroports de Paris clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.93. There's no doubt its ROE is decent, but the very high debt the company carries is not too exciting to see. 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 one way we can compare its business quality of different companies. In our books, the highest quality companies have high return on equity, despite low debt. 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. 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.
