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 ReNew Energy Global Plc (NASDAQ:RNW).

ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. Put another way, it reveals the company's success at turning shareholder investments into profits.

How To 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:

3.0% = ₹3.6b ÷ ₹120b (Based on the trailing twelve months to December 2023).

The 'return' is the yearly profit. That means that for every $1 worth of shareholders' equity, the company generated $0.03 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. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As shown in the graphic below, ReNew Energy Global has a lower ROE than the average (5.4%) in the Renewable Energy industry classification.

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.

Why You Should Consider Debt When Looking At 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 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. That will make the ROE look better than if no debt was used.

Combining ReNew Energy Global's Debt And Its 3.0% Return On Equity

It appears that ReNew Energy Global makes extensive use of debt to improve its returns, because it has an alarmingly high debt to equity ratio of 5.41. We consider it to be a negative sign when a company has a rather low ROE despite a rather high debt to equity.

Conclusion

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. All else being equal, a higher ROE is better.

Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. 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.
