What is the average HR to employee ratio?

Bloomberg/SHRM data: 1.4 HR FTE per 100 employees on average. Small companies (<250 employees): 3–4 per 100. Large (1,000+): 0.5–1 per 100.

How is the ratio changing?

HR tech automation is reducing ratios. Companies with strong HRIS, ATS, and payroll automation need fewer HR FTEs per employee.

When do I need to add HR headcount?

At 150–200 employees, specialist HR roles (HRBP, compensation, talent acquisition) typically become necessary.
