华尔街日报What Tata Power Company Limited's (NSE:TATAPOWER) ROE Can Tell Us
Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). We'll use ROE to examine Tata Power Company Limited (NSE:TATAPOWER), by way of a worked example.
Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. Simply put, it is used to assess the profitability of a company in relation to its equity capital.
How Do You Calculate Return On Equity?
Return on equity can be calculated by using the formula:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Tata Power is:
11% = ₹50b ÷ ₹449b (Based on the trailing twelve months to September 2025).
The 'return' is the yearly profit. One way to conceptualize this is that for each ₹1 of shareholders' capital it has, the company made ₹0.11 in profit.

Does Tata Power 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. You can see in the graphic below that Tata Power has an ROE that is fairly close to the average for the Electric Utilities industry (11%).
That's neither particularly good, nor bad. While at least the ROE is not lower than the industry, its still worth checking what role the company's debt plays as high debt levels relative to equity may also make the ROE appear high. 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 Tata Power visit our risks dashboard for free.
How Does Debt Impact ROE?
Virtually all companies need money to invest in the business, to grow 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 debt used for growth will improve returns, but won't affect the total equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
Tata Power's Debt And Its 11% ROE
Tata Power does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.45. Its ROE is quite low, even with the use of significant debt; that's not a good result, in our opinion. 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.
Conclusion
Return on equity is one way we can compare its business quality of different companies. Companies that can achieve high returns on equity without too much debt are generally of good quality. All else being equal, a higher ROE is better.
But when a business is high quality, the market often bids it up to a price that reflects this. 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.
