How do you measure the gap between the top executive and a typical worker at a company? One of the most direct ways is the CEO pay ratio. This metric compares the total annual compensation of a company's chief executive officer to that of its median employee.

This isn't just a number companies calculate for fun. It's a legal requirement. Following the 2008 financial crisis, the U.S. government passed the Dodd-Frank Wall Street Reform and Consumer Protection Act. A small but significant part of this massive law mandated that publicly traded companies must disclose this ratio to the public.

The CEO pay ratio serves as a quick snapshot of a company's internal pay scale. It provides a single, easy-to-understand figure that shows the income disparity between the executive suite and the general workforce.

For investors, it can be a red flag. A ratio that's extremely high compared to industry peers might raise questions about the board of directors' decisions on executive pay. For employees, it offers context for their own compensation. It helps them understand how their pay stacks up against the very top of the organizational chart.

Of course, context is key. A massive tech company with thousands of software engineers will have a different median employee salary than a retail giant with a large part-time workforce. The ratio is most useful when comparing a company to its direct competitors or to its own history over time.

Now, let's check your understanding of these core concepts.

Understanding this ratio is the first step toward analyzing how companies value their leadership and their workforce.
