Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). We’ll use ROE to examine Superior Drilling Products, Inc. (NYSEMKT:SDPI), by way of a worked example.

Superior Drilling Products has a ROE of 3.2%, based on the last twelve months. Another way to think of that is that for every \$1 worth of equity in the company, it was able to earn \$0.032.

### How Do I Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for Superior Drilling Products:

3.2% = 0.512958 ÷ US\$16m (Based on the trailing twelve months to September 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 measures a company’s profitability against the profit it retains, and any outside investments. The ‘return’ is the yearly profit. 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 Superior Drilling Products 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. If you look at the image below, you can see Superior Drilling Products has a lower ROE than the average (7.7%) in the Energy Services industry classification.

That’s not what we like to see. We’d prefer see an ROE above the industry average, but it might not matter if the company is undervalued. Still, shareholders might want to check if insiders have been selling.

### How Does Debt Impact Return On Equity?

Companies usually need to invest money to grow their 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 debt required for growth will boost returns, but will not impact the shareholders’ equity. That will make the ROE look better than if no debt was used.

### Combining Superior Drilling Products’s Debt And Its 3.2% Return On Equity

Superior Drilling Products has a debt to equity ratio of 0.69, which is far from excessive. Its ROE is certainly on the low side, and since it already uses debt, we’re not too excited about the company. Careful use of debt to boost returns is often very good for shareholders. However, it could reduce the company’s ability to take advantage of future opportunities.

### But It’s Just One Metric

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. A company that can achieve a high return on equity without debt could be considered a high quality business. All else being equal, a higher ROE is better.

But when a business is high quality, the market often bids it up to a price that reflects this. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
