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 JSW Energy Limited (NSE:JSWENERGY), by way of a worked example.
Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. Put another way, it reveals the company's success at turning shareholder investments into profits.
How Is ROE Calculated?
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for JSW Energy is:
7.9% = ₹23b ÷ ₹291b (Based on the trailing twelve months to June 2025).
The 'return' is the income the business earned over the last year. Another way to think of that is that for every ₹1 worth of equity, the company was able to earn ₹0.08 in profit.

Does JSW Energy 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. If you look at the image below, you can see JSW Energy has a similar ROE to the average in the Renewable Energy industry classification (7.7%).
So while the ROE is not exceptional, at least its acceptable. Although the ROE is similar to the industry, we should still perform further checks to see if the company's ROE is being boosted by high debt levels. If a company takes on too much debt, it is at higher risk of defaulting on interest payments. To know the 2 risks we have identified for JSW Energy visit our risks dashboard for free.
How Does Debt Impact ROE?
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 case of the first and second options, the ROE will reflect this use of cash, for growth. 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.
JSW Energy's Debt And Its 7.9% ROE
It's worth noting the high use of debt by JSW Energy, leading to its debt to equity ratio of 1.73. With a fairly low ROE, and significant use of debt, it's hard to get excited about this business at the moment. 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.
Summary
Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have the same ROE, then I would generally prefer the one with less debt.
But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
