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 Sensata Technologies Holding plc (NYSE:ST), by way of a worked example.
Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. Put another way, it reveals the company's success at turning shareholder investments into profits.

How To 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 Sensata Technologies Holding is:
4.4% = US$128m ÷ US$2.9b (Based on the trailing twelve months to December 2024).
The 'return' is the amount earned after tax over the last twelve months. One way to conceptualize this is that for each $1 of shareholders' capital it has, the company made $0.04 in profit.
Does Sensata Technologies Holding 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. If you look at the image below, you can see Sensata Technologies Holding has a lower ROE than the average (8.6%) in the Electrical industry classification.
That's not what we like to see. Although, we think that a lower ROE could still mean that a company has the opportunity to better its returns with the use of leverage, provided its existing debt levels are low. When a company has low ROE but high debt levels, we would be cautious as the risk involved is too high.

How Does Debt Impact ROE?
Companies usually need to invest money to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first two cases, the ROE will capture this use of capital to grow. 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.
Sensata Technologies Holding's Debt And Its 4.4% ROE
Sensata Technologies Holding clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.10. Its ROE is quite low, even with the use of significant debt; that's not a good result, in our opinion. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.
