Executive Support Headcount Benchmarks 2026

EA-to-Executive Ratios by Company Size

In 2026, the median ratio of executive assistants to executives supported varies significantly by organization size. At companies with fewer than 100 employees, the ratio is 1 EA per 3.4 executives: a shared-support model driven by budget constraints and lower individual executive task volume. Companies between 100 and 500 employees average 1 EA per 2.1 executives. Mid-market companies (500-5,000 employees) average 1 EA per 1.6 executives. Enterprise companies above 5,000 employees average 1 EA per 1.2 executives, with dedicated one-to-one support becoming the norm at the C-suite level.

The trend line is toward lower ratios (more dedicated support) as company size increases, reflecting both the higher task volume generated by senior executives at larger organizations and the greater institutional cost of executive inefficiency at scale. C-suite EAs supporting a CEO, CFO, or COO on a one-to-one basis represent 61% of premium EA placements in 2026.

Staffing Ratios by Revenue Tier

Revenue is a stronger predictor of EA staffing ratios than employee count in several industries. Companies below $25M in revenue average 1 EA per 4.1 executives, reflecting startup and early-growth staffing patterns. The $25M-$100M tier averages 1 EA per 2.3 executives. The $100M-$500M tier averages 1 EA per 1.7 executives. Above $500M, one-to-one support for all C-suite principals is the standard at 78% of organizations surveyed.

The $25M-$100M revenue band shows the most variability: some companies in this tier maintain shared-EA models from earlier stages, while others have moved to dedicated support as executive workloads have grown. Companies in this band that transitioned from shared to dedicated EA support reported an average 22% increase in executive-reported productivity satisfaction within six months of the change.

Specialist Roles and Support Layering

Beyond the base EA-to-executive ratio, 2026 data shows growing adoption of layered support models. Thirty-one percent of companies with more than 500 employees now employ at least one specialist role alongside generalist EAs: most commonly a board coordinator, a travel and logistics specialist, or a communications manager. These specialist roles handle high-complexity, high-volume subtasks that would otherwise pull a generalist EA away from principal-facing work.

The ROI case for specialist layering is strongest in organizations with active board programs. Companies with a dedicated board coordinator separate from the CEO's EA reduced board preparation burden on the CEO's EA by 41%, enabling that EA to expand support into strategic communications and stakeholder management. Our board meeting coordination service provides this specialist layer on an outsourced basis.

Implications for Headcount Planning

Under-staffed executive support is a common and measurable problem. Companies operating at ratios above 1 EA per 2.5 executives at the C-suite level show 34% higher principal-reported administrative burden scores than those at or below 1:1.5. The burden manifests as executives absorbing tasks that EAs should own, reducing the time available for strategic work.

Right-sizing begins with an honest audit of current task load by executive. Organizations that have conducted formal task-load audits (typically a two-week time-logging exercise) have identified an average of 11.2 additional weekly EA hours needed per C-suite principal. The audit makes the staffing case in financial terms.

Key Takeaways

The 2026 benchmark data shows that most organizations, particularly in the $25M-$500M revenue range, are under-invested in executive administrative support relative to best-practice ratios. The productivity cost of under-staffing is measurable and material. Right-sizing executive support staffing is one of the highest-ROI organizational design decisions available to leadership teams.
