The Long-Term Trajectory

Average CEO compensation at S&P 500 companies has grown from approximately $1.5 million in 1978 to over $16 million today, a roughly 1,000% increase after adjusting for inflation. Over the same period, typical worker compensation has grown approximately 12%. This divergence has made CEO-to-worker pay ratios one of the most debated topics in corporate governance.

The acceleration began in the 1990s with the widespread adoption of stock options. The Omnibus Budget Reconciliation Act of 1993 capped the tax deductibility of executive cash compensation at $1 million, ironically accelerating the shift to stock-based pay, which was not subject to the cap. This structural change transformed CEO compensation from primarily cash-based to primarily equity-based.

The Pay Ratio Disclosure Era (2018-Present)

The SEC's pay ratio disclosure rule, mandated by the Dodd-Frank Act, required companies to report CEO-to-median-worker pay ratios starting in 2018. This created the first standardized, comparable dataset on pay inequality within public companies, the data that PlainCEOPay aggregates.

Early data showed median ratios around 130:1 across the S&P 500, with wide variation by industry. Retail and fast food companies routinely exceeded 500:1 due to their large low-wage workforces. Technology companies, despite having the highest-paid CEOs in absolute terms, reported more moderate ratios because their median employees, often software engineers, earned $150,000 or more.

The Stock Compensation Shift

The composition of CEO pay has changed as dramatically as the level. In the 1990s, stock options were the dominant equity vehicle. After accounting scandals and new expensing rules in the mid-2000s, companies shifted toward restricted stock units (RSUs) and performance share units (PSUs). Today, the typical S&P 500 CEO receives 55-65% of total compensation in equity awards, 15-20% in cash bonuses, and only 10-15% as base salary.

Performance-based equity (PSUs) has been growing as a share of the mix, driven by shareholder activism and proxy advisory firms like ISS and Glass Lewis. These awards vest only if the company meets specific performance targets, often total shareholder return (TSR) relative to peers, or revenue and earnings growth. Our stock compensation guide explains how each vehicle works.

What This Means for Researchers and Investors

For investors evaluating corporate governance, the trend data matters. A company whose CEO pay is growing faster than revenue, earnings, or stock price may have a compensation committee that is not effectively linking pay to performance. Conversely, a company whose CEO pay correlates closely with shareholder returns suggests stronger alignment.
