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 Alliant Energy Corporation (NASDAQ:LNT).
Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.
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 Alliant Energy is:
11% = US$680m ÷ US$6.1b (Based on the trailing twelve months to March 2022).
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 $0.11 in profit.
Does Alliant Energy Have A Good ROE?
Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. Pleasingly, Alliant Energy has a superior ROE than the average (9.2%) in the Electric Utilities industry.
That is a good sign. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. A higher proportion of debt in a company's capital structure may also result in a high ROE, where the high debt levels could be a huge risk .

How Does Debt Impact Return On Equity?
Companies usually need to invest money 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 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.
Alliant Energy's Debt And Its 11% ROE
Alliant Energy clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.32. 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 one way we can compare its business quality of different companies. In our books, the highest quality companies have high return on equity, despite low debt. If two companies have around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.
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. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
