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. By way of learning-by-doing, we'll look at ROE to gain a better understanding of CoStar Group, Inc. (NASDAQ:CSGP).
Our data shows CoStar Group has a return on equity of 8.7% for the last year. One way to conceptualize this, is that for each $1 of shareholders' equity it has, the company made $0.087 in profit.
How Do You Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for CoStar Group:
8.7% = US$271m ÷ US$3.1b (Based on the trailing twelve months to March 2019.)
It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. It is all the money paid into the company from shareholders, plus any earnings retained. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.
What Does ROE 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. The higher the ROE, the more profit the company is making. So, as a general rule, a high ROE is a good thing. That means ROE can be used to compare two businesses.
Does CoStar Group 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. 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, CoStar Group has a lower ROE than the average (11%) in the Professional Services industry.
That certainly isn't ideal. It is better when the ROE is above industry average, but a low one doesn't necessarily mean the business is overpriced. Nonetheless, it could be useful to double-check if insiders have sold shares recently.
Why You Should Consider Debt When Looking At 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
CoStar Group's Debt And Its 8.7% ROE
Although CoStar Group does use a little debt, its debt to equity ratio of just 0.046 is very low. Its ROE isn't particularly impressive, but the debt levels are quite modest, so the business probably has some real potential. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.
Return on equity is useful for comparing the quality of different businesses. In my book the highest quality companies have high return on equity, despite low debt. 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.
But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. 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.
