Can CarMax, Inc. (NYSE:KMX) Improve Its Returns?

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. By way of learning-by-doing, we'll look at ROE to gain a better understanding of CarMax, Inc. (NYSE:KMX).

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. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How Is ROE Calculated?

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 CarMax is:

6.5% = US$403m ÷ US$6.2b (Based on the trailing twelve months to May 2024).

The 'return' is the amount earned after tax over the last twelve months. That means that for every $1 worth of shareholders' equity, the company generated $0.07 in profit.

Does CarMax Have A Good Return On Equity?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As is clear from the image below, CarMax has a lower ROE than the average (20%) in the Specialty Retail industry.

That certainly isn't ideal. 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. A high debt company having a low ROE is a different story altogether and a risky investment in our books.

Why You Should Consider Debt When Looking At ROE

Most companies need money -- from somewhere -- 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 use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.

CarMax's Debt And Its 6.5% ROE

It appears that CarMax makes extensive use of debt to improve its returns, because it has an alarmingly high debt to equity ratio of 3.04. Most investors would need a low share price to be interested in a company with low ROE and high debt to equity.

Summary

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. A company that can achieve a high return on equity without debt could be considered a high quality business. 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.
