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 Vertex, Inc. (NASDAQ:VERX), by way of a worked example.

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. Put another way, it reveals the company's success at turning shareholder investments into profits.

How Do You Calculate Return On Equity?

The formula for return on equity is:

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

So, based on the above formula, the ROE for Vertex is:

12% = US$30m ÷ US$259m (Based on the trailing twelve months to September 2024).

The 'return' is the profit over the last twelve months. So, this means that for every $1 of its shareholder's investments, the company generates a profit of $0.12.

Does Vertex 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. You can see in the graphic below that Vertex has an ROE that is fairly close to the average for the Software industry (12%).

That isn't amazing, but it is respectable. Even if the ROE is respectable when compared to the industry, its worth checking if the firm's ROE is being aided by high debt levels. If a company takes on too much debt, it is at higher risk of defaulting on interest payments.

Why You Should Consider Debt When Looking At 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 first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Vertex's Debt And Its 12% ROE

Vertex clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.29. The combination of a rather low ROE and significant use of debt is not particularly appealing. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.

Conclusion

Return on equity is one way we can compare its business quality of different companies. In our books, 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.

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.
