How Do I Calculate ROE?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for Buzzi Unicem:

12% = €394m ÷ €3.4b (Based on the trailing twelve months to June 2019.)

Most know that net profit is the total earnings after all expenses, but the concept of shareholders' equity is a little more complicated. It is all earnings retained by the company, plus any capital paid in by shareholders. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.

What Does Return On Equity Signify?

ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the amount earned after tax over the last twelve months. That means that the higher the ROE, the more profitable the company is. So, all else equal, investors should like a high ROE. Clearly, then, one can use ROE to compare different companies.

Does Buzzi Unicem Have A Good Return On Equity?

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. If you look at the image below, you can see Buzzi Unicem has a similar ROE to the average in the Basic Materials industry classification (10%).

That's neither particularly good, nor bad. ROE doesn't tell us if the share price is low, but it can inform us to the nature of the business. For those looking for a bargain, other factors may be more important. I will like Buzzi Unicem better if I see some big insider buys.

Why You Should Consider Debt When Looking At ROE

Companies usually need to invest money 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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Buzzi Unicem's Debt And Its 12% ROE

Buzzi Unicem has a debt to equity ratio of 0.39, which is far from excessive. Its very respectable ROE, combined with only modest debt, suggests the business is in good shape. Conservative use of debt to boost returns is usually a good move for shareholders, though it does leave the company more exposed to interest rate rises.

In Summary

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. In my book 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.
