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. By way of learning-by-doing, we'll look at ROE to gain a better understanding of Experian plc (LON:EXPN).
ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. Put another way, it reveals the company's success at turning shareholder investments into profits.

How Is ROE Calculated?
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 Experian is:
27% = US$960m ÷ US$3.6b (Based on the trailing twelve months to September 2022).
The 'return' refers to a company's earnings over the last year. So, this means that for every £1 of its shareholder's investments, the company generates a profit of £0.27.
Does Experian Have A Good Return On Equity?
Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As you can see in the graphic below, Experian has a higher ROE than the average (21%) in the Professional Services industry.
That's clearly a positive. With that said, a high ROE doesn't always indicate high profitability. A higher proportion of debt in a company's capital structure may also result in a high ROE, where the high debt levels could be a huge risk .
How Does Debt Impact Return On Equity?
Most companies need money -- from somewhere -- 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 debt used for growth will improve returns, but won't affect the total equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Experian's Debt And Its 27% ROE
It's worth noting the high use of debt by Experian, leading to its debt to equity ratio of 1.06. While no doubt that its ROE is impressive, we would have been even more impressed had the company achieved this with lower debt. 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.
