While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. We'll use ROE to examine Wipro Limited (NSE:WIPRO), by way of a worked example.
Over the last twelve months Wipro has recorded a ROE of 16%. That means that for every ₹1 worth of shareholders' equity, it generated ₹0.16 in profit.

How Do I Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Wipro:
16% = ₹90b ÷ ₹571b (Based on the trailing twelve months to March 2019.)
It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. 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?
ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the amount earned after tax over the last twelve months. A higher profit will lead to a higher ROE. So, as a general rule, a high ROE is a good thing. That means ROE can be used to compare two businesses.
Does Wipro 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. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As you can see in the graphic below, Wipro has a higher ROE than the average (11%) in the IT industry.
That's clearly a positive. In my book, a high ROE almost always warrants a closer look. For example, I often check if insiders have been buying shares .
Why You Should Consider Debt When Looking At ROE
Companies usually need to invest money to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.
Wipro's Debt And Its 16% ROE
Although Wipro does use debt, its debt to equity ratio of 0.17 is still low. The combination of modest debt and a very respectable ROE suggests this is a business worth watching. 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.
