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 CMS Energy Corporation (NYSE:CMS), by way of a worked example.
Our data shows CMS Energy has a return on equity of 12% for the last year. One way to conceptualize this, is that for each $1 of shareholders’ equity it has, the company made $0.12 in profit.

How Do You Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for CMS Energy:
12% = US$583m ÷ US$4.9b (Based on the trailing twelve months to June 2019.)
Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is the capital paid in by shareholders, plus any retained earnings. You can calculate shareholders’ equity by subtracting the company’s total liabilities from its total assets.
What Does ROE Signify?
ROE looks at the amount a company earns relative to the money it has kept within the business. The ‘return’ is the amount earned after tax over the last twelve months. That means that the higher the ROE, the more profitable the company is. So, as a general rule, a high ROE is a good thing. That means it can be interesting to compare the ROE of different companies.
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. You can see in the graphic below that CMS Energy has an ROE that is fairly close to the average for the Integrated Utilities industry (10%).
That isn’t amazing, but it is respectable. ROE can give us a view about company quality, but many investors also look to other factors, such as whether there are insiders buying shares.

How Does Debt Impact ROE?
Companies usually need to invest money to grow their 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 use of debt will improve the returns, but will not change the equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
CMS Energy’s Debt And Its 12% ROE
CMS Energy does use a significant amount of debt to increase returns. It has a debt to equity ratio of 2.52. while its ROE is respectable, it is worth keeping in mind that there is usually a limit to how much debt a company can use. 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.
In Summary
Return on equity is one way we can compare the business quality of different companies. In my book 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.
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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider. So I think it may be worth checking this free report on analyst forecasts for the company.
