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. We'll use ROE to examine IPG Photonics Corporation (NASDAQ:IPGP), by way of a worked example.
IPG Photonics has a ROE of 11%, based on the last twelve months. Another way to think of that is that for every $1 worth of equity in the company, it was able to earn $0.11.
How Do I Calculate Return On Equity?
The formula for return on equity is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
Or for IPG Photonics:
11% = US$260m ÷ US$2.4b (Based on the trailing twelve months to September 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. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.
What Does ROE Mean?
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. A higher profit will lead to a higher ROE. 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 IPG Photonics 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. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. The image below shows that IPG Photonics has an ROE that is roughly in line with the Electronic industry average (12%).
That's neither particularly good, nor bad. ROE doesn't tell us if the share price is low, but it can inform us to the nature of the business. For those looking for a bargain, other factors may be more important. If you like to buy stocks alongside management, then you might just love this free list of companies.

How Does Debt Impact 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 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. That will make the ROE look better than if no debt was used.
IPG Photonics's Debt And Its 11% ROE
Although IPG Photonics does use a little debt, its debt to equity ratio of just 0.018 is very low. Its very respectable ROE, combined with only modest debt, suggests the business is in good shape. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.
The Key Takeaway
Return on equity is useful for comparing the quality of different businesses. Companies that can achieve high returns on equity without too much debt are generally of good quality. 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. So I think it may be worth checking this free report on analyst forecasts for the company.
