How Do You Calculate ROE?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for GMS:

8.9% = US$55m ÷ US$629m (Based on the trailing twelve months to April 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. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.

What Does ROE Signify?

Return on Equity measures a company's profitability against the profit it has kept for the business (plus any capital injections). 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, all else equal, investors should like a high ROE. That means ROE can be used to compare two businesses.

Does GMS 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. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. If you look at the image below, you can see GMS has a lower ROE than the average (11%) in the Trade Distributors industry classification.

Unfortunately, that's sub-optimal. We prefer it when the ROE of a company is above the industry average, but it's not the be-all and end-all if it is lower. Nonetheless, it could be useful to double-check if insiders have sold shares recently.

How Does Debt Impact Return On Equity?

Virtually all companies need money to invest in the business, to grow profits. That cash can come from issuing shares, retained earnings, 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 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.

Combining GMS's Debt And Its 8.9% Return On Equity

GMS does use a significant amount of debt to increase returns. It has a debt to equity ratio of 1.81. While the ROE isn't too bad, it would probably be a lot lower if the company was forced to reduce debt. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.

The Key Takeaway

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 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.
