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. To keep the lesson grounded in practicality, we'll use ROE to better understand Sterlite Technologies Limited (NSE:STRTECH).
Over the last twelve months Sterlite Technologies has recorded a ROE of 39%. Another way to think of that is that for every ₹1 worth of equity in the company, it was able to earn ₹0.39.

How Do I Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Sterlite Technologies:
39% = ₹5.2b ÷ ₹14b (Based on the trailing twelve months to December 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. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.
What Does Return On Equity 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 yearly profit. A higher profit will lead to a higher ROE. So, all else being equal, a high ROE is better than a low one. That means ROE can be used to compare two businesses.
Does Sterlite Technologies 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 is clear from the image below, Sterlite Technologies has a better ROE than the average (13%) in the Communications industry.
That's clearly a positive. We think a high ROE, alone, is usually enough to justify further research into a company. One data point to check is if insiders have bought shares recently.
The Importance Of Debt To Return On Equity
Virtually all companies need money to invest in the business, to grow profits. That cash can come from issuing shares, retained earnings, or debt. In the first and second cases, the ROE will reflect this use of cash for investment in the business. 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.
