How Do You Calculate ROE?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for Solaria Energía y Medio Ambiente:

13% = €23m ÷ €176m (Based on the trailing twelve months to March 2019.)

Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is all the money paid into the company from shareholders, plus any earnings retained. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.

What Does ROE Mean?

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, as a general rule, a high ROE is a good thing. That means ROE can be used to compare two businesses.

Does Solaria Energía y Medio Ambiente 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 is clear from the image below, Solaria Energía y Medio Ambiente has a better ROE than the average (9.1%) in the Renewable Energy industry.

That's what I like to see. We think a high ROE, alone, is usually enough to justify further research into a company. One data point to check is if insiders have bought shares recently.

The Importance Of Debt To Return On Equity

Virtually all companies need money to invest in the business, to grow profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. 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. That will make the ROE look better than if no debt was used.

Solaria Energía y Medio Ambiente's Debt And Its 13% ROE

It's worth noting the significant use of debt by Solaria Energía y Medio Ambiente, leading to its debt to equity ratio of 1.15. Its ROE is quite good but, it would have probably been lower without the use of 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.

The Bottom Line On ROE

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. Companies that can achieve high returns on equity without too much debt are generally of good quality. If two companies have the same ROE, then I would generally prefer the one with less debt.

Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. 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.
