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 CMS Energy Corporation (NYSE:CMS).
Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.
How Do You Calculate Return On Equity?
ROE 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 CMS Energy is:
11% = US$979m ÷ US$8.9b (Based on the trailing twelve months to March 2025).
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 CMS Energy 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 you can see in the graphic below, CMS Energy has a higher ROE than the average (8.9%) in the Integrated Utilities industry.
That's what we like to see. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk.

The Importance Of Debt To Return On Equity
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 debt required for growth will boost returns, but will not impact the shareholders' equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
Combining CMS Energy's Debt And Its 11% Return On Equity
CMS Energy does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.89. The combination of a rather low ROE and significant use of debt is not particularly appealing. 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.
Summary
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. All else being equal, a higher ROE is better.
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 I think it may be worth checking this free report on analyst forecasts for the company.
