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 Coherent, Inc. (NASDAQ:COHR).
Our data shows Coherent has a return on equity of 1.8% for the last year. One way to conceptualize this, is that for each $1 of shareholders’ equity it has, the company made $0.02 in profit.

How Do You Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders’ Equity
Or for Coherent:
1.8% = US$24m ÷ US$1.3b (Based on the trailing twelve months to December 2019.)
It’s easy to understand the ‘net profit’ part of that equation, but ‘shareholders’ equity’ requires further explanation. It is all earnings retained by the company, plus any capital paid in by shareholders. The easiest way to calculate shareholders’ equity is to subtract the company’s total liabilities from the 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 yearly profit. The higher the ROE, the more profit the company is making. So, all else equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.
Does Coherent Have A Good Return On Equity?
By comparing a company’s ROE with its industry average, we can get a quick measure of how good it is. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. If you look at the image below, you can see Coherent has a lower ROE than the average (12%) in the Electronic industry classification.

That’s not what we like to see. We prefer it when the ROE of a company is above the industry average, but it’s not the be-all and end-all if it is lower. Still, shareholders might want to check if insiders have been selling.
Why You Should Consider Debt When Looking At ROE
Companies usually need to invest money to grow their profits. That cash can come from issuing shares, retained earnings, 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 debt required for growth will boost returns, but will not impact the shareholders’ equity. That will make the ROE look better than if no debt was used.
Coherent’s Debt And Its 1.8% ROE
Although Coherent does use debt, its debt to equity ratio of 0.32 is still low. Its ROE is rather low, and it does use some debt, albeit not much. That’s not great to see. Conservative use of debt to boost returns is usually a good move for shareholders, though it does leave the company more exposed to interest rate rises.
The Bottom Line On ROE
Return on equity is useful for comparing the quality of different businesses. A company that can achieve a high return on equity without debt could be considered a high quality business. 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. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
