To keep the lesson grounded in practicality, we'll use ROE to better understand MercadoLibre, Inc. (NASDAQ:MELI).

Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

How To Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for MercadoLibre is:

34% = US$757m ÷ US$2.3b (Based on the trailing twelve months to June 2023).

The 'return' is the income the business earned over the last year. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.34 in profit.

Does MercadoLibre 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. Pleasingly, MercadoLibre has a superior ROE than the average (18%) in the Multiline Retail industry.

That is a good sign. With that said, a high ROE doesn't always indicate high profitability. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk.

The Importance Of Debt To Return On Equity

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 case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the use of debt will improve the returns, but will not change the equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Combining MercadoLibre's Debt And Its 34% Return On Equity

MercadoLibre clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 2.09. 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.

Summary

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. All else being equal, a higher ROE is better.

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.
