How Do I Calculate ROE?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for Zoom Video Communications:

1.7% = US$5.0m ÷ US$744m (Based on the trailing twelve months to July 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 all earnings retained by the company, plus any capital paid in by shareholders. 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?

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 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 it can be interesting to compare the ROE of different companies.

Does Zoom Video Communications Have A Good ROE?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As shown in the graphic below, Zoom Video Communications has a lower ROE than the average (9.1%) in the Software 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. Nonetheless, it could be useful to double-check if insiders have sold shares recently.

The Importance Of Debt To Return On Equity

Most companies need money -- from somewhere -- to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. 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 used for growth will improve returns, but won't affect the total equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Combining Zoom Video Communications's Debt And Its 1.7% Return On Equity

Zoom Video Communications is free of net debt, which is a positive for shareholders. It's hard to argue its ROE is much good, but the fact that no debt was used is some comfort. After all, when a company has a strong balance sheet, it can often find ways to invest in growth, even if it takes some time.

But It's Just One Metric

Return on equity is useful for comparing the quality of different businesses. Companies that can achieve high returns on equity without too much debt are generally of good quality. All else being equal, a higher ROE is better.

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. 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. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
