While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. We'll use ROE to examine GIEAG Immobilien AG (MUN:2GI), by way of a worked example.

Over the last twelve months GIEAG Immobilien has recorded a ROE of 53%. One way to conceptualize this, is that for each â‚¬1 of shareholders' equity it has, the company made â‚¬0.53 in profit.

### How Do I Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit Ã· Shareholders' Equity

Or for GIEAG Immobilien:

53% = â‚¬27m Ã· â‚¬51m (Based on the trailing twelve months to December 2018.)

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 the money paid into the company from shareholders, plus any earnings retained. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.

### What Does Return On Equity Mean?

ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the yearly profit. A higher profit will lead to a higher ROE. So, all else equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.

### Does GIEAG Immobilien 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. 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, GIEAG Immobilien has a higher ROE than the average (12%) in the Real Estate industry.

That's clearly a positive. In my book, a high ROE almost always warrants a closer look. For example you might check if insiders are buying shares.

### How Does Debt Impact ROE?

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 first two cases, the ROE will capture this use of capital to grow. In the latter case, the use of debt will improve the returns, but will not change the equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

### GIEAG Immobilien's Debt And Its 53% ROE

It seems that GIEAG Immobilien uses a lot of debt to fund the business, since it has a high debt to equity ratio of 3.77. Its ROE is no doubt quite impressive, but it would probably be a lot lower without the use of significant leverage.

### But It's Just One Metric

Return on equity is useful for comparing the quality of different businesses. Companies that can achieve high returns on equity without too much debt are generally of good quality. 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.

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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
