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. By way of learning-by-doing, we'll look at ROE to gain a better understanding of Deutsche Grundstücksauktionen AG (ETR:DGR).

ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. Put another way, it reveals the company's success at turning shareholder investments into profits.

How Do You Calculate Return On Equity?

Return on equity can be calculated by using the formula:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Deutsche Grundstücksauktionen is:

18% = €2.0m ÷ €11m (Based on the trailing twelve months to June 2022).

The 'return' is the amount earned after tax over the last twelve months. 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 Deutsche Grundstücksauktionen 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, Deutsche Grundstücksauktionen has a higher ROE than the average (8.2%) in the Real Estate industry.

That's what we like to see. 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

Most companies need money -- from somewhere -- to grow their 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Deutsche Grundstücksauktionen's Debt And Its 18% ROE

Deutsche Grundstücksauktionen is free of net debt, which is a positive for shareholders. Its ROE already suggests it is a good business, but the fact it has achieved this -- and doesn't borrowings -- makes it worthy of further consideration, in our view. After all, with cash on the balance sheet, a company has a lot more optionality in good times and bad.

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. All else being equal, a higher ROE is better.

But when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward. So I think it may be worth checking this free report on analyst forecasts for the company.
