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 ReNew Energy Global Plc (NASDAQ:RNW), 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. Put another way, it reveals the company's success at turning shareholder investments into profits.

How Do You Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for ReNew Energy Global is:

2.3% = ₹2.8b ÷ ₹124b (Based on the trailing twelve months to September 2023).

The 'return' is the profit over the last twelve months. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.02 in profit.

Does ReNew Energy Global 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. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As is clear from the image below, ReNew Energy Global has a lower ROE than the average (4.5%) in the Renewable Energy industry.

That certainly isn't ideal. Although, we think that a lower ROE could still mean that a company has the opportunity to better its returns with the use of leverage, provided its existing debt levels are low. A company with high debt levels and low ROE is a combination we like to avoid given the risk involved.

How Does Debt Impact ROE?

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 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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

ReNew Energy Global's Debt And Its 2.3% ROE

We think ReNew Energy Global uses a significant amount of debt to maximize its returns, as it has a significantly higher debt to equity ratio of 4.74. The combination of a rather low ROE and high debt to equity is a negative, in our book.

Summary

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. In our books, the highest quality companies have high return on equity, despite low debt. 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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider. So I think it may be worth checking this free report on analyst forecasts for the company.
