Russell 3000 CEO Compensation: The Universe You Actually Belong To

Your comp committee is benchmarking against the wrong index

Your compensation committee's outside counsel just circulated a peer group memo, and every company on it trades north of $50 billion in market capitalization. You run a company with $1.4 billion in revenue, and your public float barely clears the line between small-cap and mid-cap. The memo tells your board what a mega-cap CEO earns. It tells you almost nothing about what your own board should pay you.

This is the most common benchmarking error in small- and mid-cap executive pay: pulling headline compensation figures built for the S&P 500 and applying them to a company that competes in a different labor market entirely. The S&P 500 covers 500 companies. The broader universe most public-company CEOs actually belong to — for peer comparison, for labor-market competition, and for comp-committee credibility — is the Russell 3000. By the end of this article, you will know why that index is the correct starting point for your benchmark, how CEO pay and CEO profile shift as you move down the size spectrum inside it, and how to size a peer group your board can defend.

Why the S&P 500 headline number is not your number

Median S&P 500 CEO total compensation reached $17.1 million in 2024, up 9.7% year over year, per the Equilar / Associated Press CEO Pay Study for 2025 covering fiscal year 2024. Average S&P 500 CEO pay was higher still, at $18.9 million in 2024, with an average CEO-to-worker pay ratio of 285:1, according to the AFL-CIO Executive Paywatch report for 2025. Those numbers describe the 500 largest publicly traded US companies by market capitalization — a group selected specifically because of its size, not its representativeness of the broader public-company market.

The Russell 3000 is a different instrument. It measures roughly 3,000 US companies and represents approximately 98% of investable US equity market capitalization, according to LSEG / FTSE Russell index documentation for 2025. That means well over 2,500 of its constituents sit outside the S&P 500 entirely — companies with revenue, headcount, and governance structures that look nothing like a mega-cap's. If your company is one of them, an S&P 500 median is not a benchmark. It is a number from a different labor market.

What the Russell 3000 actually measures

The Russell 3000 is a market-capitalization-weighted index spanning nearly the entire investable US equity market — large-cap, mid-cap, and small-cap companies together, per LSEG / FTSE Russell (2025). That breadth is exactly what makes it useful for russell 3000 ceo compensation benchmarking: it is the closest single index to "the full population of US public companies your board can plausibly compare you against," rather than a curated slice of the largest names.

Within that universe, compensation practice is not uniform. CEO pay in the Russell 3000 compresses and expands with company size, sector, and ownership structure in ways a single median obscures. That is the case for treating the Russell 3000 as a starting universe to be segmented, not a single number to be quoted at the board table.

How pay structure shifts by company size inside the index

Two data points illustrate how differently the Russell 3000 behaves compared with its S&P 500 subset.

First, pay compression between the CEO and the rest of the executive team is tighter outside the largest companies. All non-CEO named executive officers' total compensation combined equaled 38% of CEO pay in the Russell 3000, versus 31% in the S&P 500, for fiscal year 2024, according to the Harvard Law School Forum on Corporate Governance (2025). In plainer terms: as company size shrinks, the gap between the CEO's pay and the rest of the leadership team narrows. A comp committee benchmarking a $1 billion-revenue CEO against S&P 500 pay ratios is implicitly assuming a wider internal pay spread than actually exists at that scale.

Second, succession patterns differ by index segment. Internal CEO hires accounted for 59% of Russell 3000 successions in 2024, compared with 77% in the S&P 500 the same year, per The Conference Board (2024). A year later, Russell 3000 successions were 65% internal in 2025, up from 62% in 2024, per The Conference Board (2025). Smaller and mid-cap boards go outside for CEO talent more often than the largest companies do — which matters directly for negotiation, since externally hired CEOs are paid differently than internally promoted ones. Among S&P 500 companies, externally hired CEOs' median total pay was $10.99 million versus $7.76 million for internal hires — roughly a 41.6% gap — according to Equilar (2015). That specific gap is an S&P 500 figure, not a Russell 3000 one, but the underlying dynamic — external hires command a premium — is directly relevant if your own path to the corner office ran through a search firm rather than an internal succession plan.

For the specific median figure inside the broader Russell 3000 itself, see our companion breakdown at median CEO total compensation in the Russell 3000 — it is worth pulling as a standalone reference rather than treating a Russell 3000 number and an S&P 500 number as interchangeable.

Building a peer group you can actually defend

The Russell 3000 is a universe, not a peer group. Turning it into one requires the same segmentation logic any credible compensation analysis uses:

• Sector classification. SIC and NAICS codes are the standard systems for identifying companies in your competitive and labor-market sector — a necessary filter before comparing pay at all.
• Revenue band. CEO pay scales with company size far more reliably than with any other single variable; a peer set spanning three orders of magnitude in revenue produces a meaningless median. See CEO pay by company size for how that scaling works in practice, and small-cap CEO compensation if your company sits at the smaller end of the Russell 3000.
• Ownership type and region. A controlled company, a recently public company, and a widely held company set pay differently even at similar revenue; region affects both cost of labor and disclosure norms.
• A minimum peer-group size. A peer set of four or five companies is too thin to defend against a comp committee holding a structured survey with dozens of data points behind it.

A benchmark built from the wrong index answers a question nobody asked; a benchmark built from an unsegmented index answers the right question badly.

Where these numbers actually come from

Every figure cited above traces back to public company disclosures. Proxy statements generally disclose compensation for the top five most highly paid executive officers — the named executive officers, including the CEO and CFO — in the Summary Compensation Table, per Meridian Compensation Partners (2025). CEO Pay Ratio disclosure, under Item 402(u) of Regulation S-K, was adopted August 5, 2015, under Section 953(b) of Dodd-Frank, and requires companies to disclose CEO total compensation against median-employee total compensation annually, per the Harvard Law School Forum on Corporate Governance (2015). Pay Versus Performance disclosure, under Item 402(v), was adopted August 25, 2022, and became effective for 2023 proxy statements, mandating Inline XBRL tagging, per Mintz (2022) — Inline XBRL being a structured data format that produces a single filing readable by both humans and machines, per SEC.gov (2024). That machine-readable pay data lives in the proxy or information statement, not in the annual report on Form 10-K, per Greenberg Traurig (2023). All of it is available free through SEC EDGAR, per SEC.gov (2025).

That also means director compensation — disclosed in the same proxy, in its own table — is a separate benchmarking question from CEO compensation, with its own peer-group logic; this article does not attempt to state a Russell 3000 director-pay figure, and you should confirm current director compensation benchmarks directly against the filings for your chosen peer set.

The studies cited throughout this piece aggregate figures across many individual DEF 14A filings rather than quoting a single company's proxy. If you want the underlying number for a specific peer, EDGAR is the source document — the aggregate studies tell you where the market sits; the individual filing tells you where one company sits within it.

Turning the index into your number

A correctly segmented Russell 3000 peer set — by sector, revenue band, ownership type, and region, filtered against a minimum group size — gives your comp committee a defensible position instead of a borrowed S&P 500 headline. Our Sector Benchmark Report builds that peer set from DEF 14A Summary Compensation Table data, cross-validated against XBRL-tagged Pay Versus Performance and CEO Pay Ratio disclosures, and positions you by percentile — 25th, 50th, 75th, and 90th — with every figure cited to its source filing.
