How Do I Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for China Primary Energy Holdings:

0.1% = HK$2.8m ÷ HK$417m (Based on the trailing twelve months to June 2019.)

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 the capital paid in by shareholders, plus any retained earnings. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.

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 profit over the last twelve months. That means that the higher the ROE, the more profitable the company is. So, as a general rule, a high ROE is a good thing. That means ROE can be used to compare two businesses.

Does China Primary Energy Holdings Have A Good ROE?

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 China Primary Energy Holdings has a lower ROE than the average (11%) in the Gas Utilities industry classification.

Unfortunately, that's sub-optimal. 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.

The Importance Of Debt To Return On Equity

Most companies need money -- from somewhere -- to grow their 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 required for growth will boost returns, but will not impact the shareholders' equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Combining China Primary Energy Holdings's Debt And Its 0.1% Return On Equity

China Primary Energy Holdings has a debt to equity ratio of 0.13, 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. Conservative use of debt to boost returns is usually a good move for shareholders, though it does leave the company more exposed to interest rate rises.

The Key Takeaway

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. If two companies have the same ROE, then I would generally prefer the one with less debt.

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.
