What is Return On Capital Employed (ROCE)?

ROCE is a metric for evaluating how much pre-tax income (in percentage terms) a company earns on the capital invested in its business. In general, businesses with a higher ROCE are usually better quality. In brief, it is a useful tool, but it is not without drawbacks. Author Edwin Whiting says to be careful when comparing the ROCE of different businesses, since 'No two businesses are exactly alike.

So, How Do We Calculate ROCE?

Analysts use this formula to calculate return on capital employed:

Return on Capital Employed = Earnings Before Interest and Tax (EBIT) ÷ (Total Assets - Current Liabilities)

Or for AutoZone:

0.33 = US$2.2b ÷ (US$13b - US$5.9b) (Based on the trailing twelve months to November 2019.)

So, AutoZone has an ROCE of 33%.

Remember that this metric is backwards looking - it shows what has happened in the past, and does not accurately predict the future. ROCE can be misleading for companies in cyclical industries, with returns looking impressive during the boom times, but very weak during the busts. ROCE is only a point-in-time measure.

Do AutoZone's Current Liabilities Skew Its ROCE?

Liabilities, such as supplier bills and bank overdrafts, are referred to as current liabilities if they need to be paid within 12 months. Due to the way the ROCE equation works, having large bills due in the near term can make it look as though a company has less capital employed, and thus a higher ROCE than usual. To counter this, investors can check if a company has high current liabilities relative to total assets.

AutoZone has current liabilities of US$5.9b and total assets of US$13b. As a result, its current liabilities are equal to approximately 46% of its total assets. A medium level of current liabilities boosts AutoZone's ROCE somewhat.
