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 ExlService Holdings, Inc. (NASDAQ:EXLS), by way of a worked example.

Our data shows ExlService Holdings has a return on equity of 7.6% for the last year. That means that for every $1 worth of shareholders’ equity, it generated $0.076 in profit.

How Do You Calculate ROE?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for ExlService Holdings:

7.6% = 43.514 ÷ US$574m (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 ROE Mean?

ROE looks at the amount a company earns relative to the money it has kept within the business. The ‘return’ is the yearly profit. A higher profit will lead to a higher ROE. So, all else equal, investors should like a high ROE. Clearly, then, one can use ROE to compare different companies.

Does ExlService Holdings Have A Good ROE?

One simple way to determine if a company has a good return on equity is to compare it to the average for 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 ExlService Holdings has a lower ROE than the average (15%) in the IT industry classification.

That certainly isn’t ideal. It is better when the ROE is above industry average, but a low one doesn’t necessarily mean the business is overpriced. Nonetheless, it might be wise 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

ExlService Holdings’s Debt And Its 7.6% ROE

While ExlService Holdings does have some debt, with debt to equity of just 0.52, we wouldn’t say debt is excessive. Although the ROE isn’t overly impressive, the debt load is modest, suggesting the business has potential. 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 Bottom Line On ROE

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

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. It is important to consider other factors, such as future profit growth — and how much investment is required going forward.
