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. To keep the lesson grounded in practicality, we'll use ROE to better understand CESC Limited (NSE:CESC).
Our data shows CESC has a return on equity of 13% for the last year. One way to conceptualize this, is that for each ₹1 of shareholders' equity it has, the company made ₹0.13 in profit.

How Do I Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for CESC:
13% = ₹12b ÷ ₹91b (Based on the trailing twelve months to June 2019.)
Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is all earnings retained by the company, plus any capital paid in by shareholders. You can calculate shareholders' equity by subtracting the company's total liabilities from its 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 profit over the last twelve months. The higher the ROE, the more profit the company is making. So, as a general rule, a high ROE is a good thing. Clearly, then, one can use ROE to compare different companies.
Does CESC Have A Good Return On Equity?
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. Pleasingly, CESC has a superior ROE than the average (11%) company in the Electric Utilities industry.
That's what I like to see. I usually take a closer look when a company has a better ROE than industry peers. For example you might check if insiders are buying shares.
How Does Debt Impact 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 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.
Combining CESC's Debt And Its 13% Return On Equity
It's worth noting the significant use of debt by CESC, leading to its debt to equity ratio of 1.60. While the ROE isn't too bad, it would probably be a lot lower if the company was forced to reduce debt. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.
