How Do You Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for Quest Diagnostics:

14% = US$707m ÷ US$5.6b (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. You can calculate shareholders’ equity by subtracting the company’s total liabilities from its total assets.

What Does Return On Equity Mean?

ROE looks at the amount a company earns relative to the money it has kept within the business. The ‘return’ is the profit over the last twelve months. The higher the ROE, the more profit the company is making. So, all else being equal, a high ROE is better than a low one. Clearly, then, one can use ROE to compare different companies.

Does Quest Diagnostics Have A Good ROE?

Arguably the easiest way to assess company’s ROE is to compare it with the average in its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. If you look at the image below, you can see Quest Diagnostics has a similar ROE to the average in the Healthcare industry classification (13%).

That’s neither particularly good, nor bad. ROE can give us a view about company quality, but many investors also look to other factors, such as whether there are insiders buying shares. If you are like me, then you will not want to miss this free list of growing companies that insiders are buying.

Why You Should Consider Debt When Looking At ROE

Virtually all companies need money to invest in the business, to grow profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first two cases, the ROE will capture this use of capital to grow. 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.

Quest Diagnostics’s Debt And Its 14% ROE

While Quest Diagnostics does have some debt, with debt to equity of just 0.72, we wouldn’t say debt is excessive. Its very respectable ROE, combined with only modest debt, suggests the business is in good shape. 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 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. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
