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 South Jersey Industries, Inc. (NYSE:SJI), 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 Is ROE Calculated?
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 South Jersey Industries is:
4.8% = US$91m ÷ US$1.9b (Based on the trailing twelve months to June 2021).
The 'return' is the income the business earned over the last year. That means that for every $1 worth of shareholders' equity, the company generated $0.05 in profit.
Does South Jersey Industries 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. If you look at the image below, you can see South Jersey Industries has a lower ROE than the average (9.5%) in the Gas Utilities industry classification.
Unfortunately, that's sub-optimal. However, a low ROE is not always bad. If the company's debt levels are moderate to low, then there's still a chance that returns can be improved via the use of financial leverage. A high debt company having a low ROE is a different story altogether and a risky investment in our books.

Why You Should Consider Debt When Looking At ROE
Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, 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.
Combining South Jersey Industries' Debt And Its 4.8% Return On Equity
It's worth noting the high use of debt by South Jersey Industries, leading to its debt to equity ratio of 1.74. 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.
Return on equity is useful for comparing the quality of different businesses. 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 when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
