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 OHB SE (ETR:OHB), by way of a worked example.
OHB has a ROE of 14%, based on the last twelve months. One way to conceptualize this, is that for each €1 of shareholders' equity it has, the company made €0.14 in profit.

How Do I Calculate Return On Equity?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for OHB:
14% = €25m ÷ €200m (Based on the trailing twelve months to December 2018.)
Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is the capital paid in by shareholders, plus any retained earnings. 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. The higher the ROE, the more profit the company is making. So, all else being equal, a high ROE is better than a low one. That means it can be interesting to compare the ROE of different companies.
Does OHB 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. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As you can see in the graphic below, OHB has a higher ROE than the average (11%) in the Aerospace & Defense industry.
That's clearly a positive. In my book, a high ROE almost always warrants a closer look. One data point to check is if insiders have bought shares recently.
How Does Debt Impact ROE?
Virtually all companies need money to invest in the business, to grow profits. That cash can come from retained earnings, issuing new shares (equity), 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.
