While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. To keep the lesson grounded in practicality, we’ll use ROE to better understand Prudential Financial, Inc. (NYSE:PRU).
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.
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders’ Equity
So, based on the above formula, the ROE for Prudential Financial is:
8.2% = US$2.9b ÷ US$35b (Based on the trailing twelve months to September 2025).
The ‘return’ is the profit over the last twelve months. That means that for every $1 worth of shareholders’ equity, the company generated $0.08 in profit.

By comparing a company’s ROE with its industry average, we can get a quick measure of how good it is. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. If you look at the image below, you can see Prudential Financial has a lower ROE than the average (13%) in the Insurance industry classification.
That’s not what we like to see. That being said, a low ROE is not always a bad thing, especially if the company has low leverage as this still leaves room for improvement if the company were to take on more debt. When a company has low ROE but high debt levels, we would be cautious as the risk involved is too high.
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 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. That will make the ROE look better than if no debt was used.
Prudential Financial clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.49. 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.
