Professional Services Industry Benchmarks
Calculation Methodology
Current Cost Calculation: We sum all direct HR costs (staff compensation, payroll processing, workers' comp, health benefits, compliance, EPLI, recruiting) plus the opportunity cost of owner time spent on HR activities (valued at $75/hour).
PEO Cost Calculation: PEO admin fee x employees x 12 months, plus adjusted health benefits cost (reduced by 11% through PEO group purchasing), plus adjusted workers' comp (reduced by 15% through PEO pooled programs).
Hidden Savings: We calculate additional PEO value from: (1) Turnover reduction — PEO clients average 10-14% lower turnover (NAPEO data), valued at the industry-specific replacement cost; (2) Compliance penalty avoidance — estimated at $3,500/year average for the professional services industry; (3) EPLI coverage value — typically $3,000-$8,000/year when purchased separately.
Limitations: Actual PEO costs vary by provider, location, and specific services included. This calculator provides estimates based on industry averages. Request actual PEO quotes for accurate pricing.

Why Professional Services Businesses Use PEOs
Professional services firms — including accounting, consulting, engineering, and architecture practices — compete intensely for talent. With average salaries of $78,000 and replacement costs of 125% of salary, retention through competitive benefits is essential.
Workers' compensation costs are low ($0.65 per $100 of payroll) since the work is primarily office-based, but the benefits and HR complexity is where professional services firms need help. PEOs enable mid-size professional firms to offer benefits packages comparable to Big Four accounting firms or national consulting companies.
Professional licensing tracking, continuing education requirements, and state-specific practice regulations add compliance complexity. PEOs can integrate licensing tracking into their HR platform, ensuring professionals maintain required credentials.
Many professional services firms are growing through remote and hybrid work models, creating multi-state compliance obligations. PEOs handle state registrations, withholding, and employment law compliance across all states where team members are located.
What a PEO costs a professional services firm
Small and mid-size professional services firms compete for talent against larger employers with richer benefits. A PEO levels that field by pooling the firm into a large group for benefits, while handling payroll, compliance, and HR so partners can focus on client work.
PEOs price as a percentage of payroll or a flat per-employee-per-month fee. This calculator estimates the cost against your headcount and payroll so you can compare it to in-house administration and standalone benefits.
What this calculator accounts for:
- Large-group benefits to compete for talent
- Payroll and HR compliance off the partners' plate
- Onboarding and employee administration
- Access to retirement and ancillary benefits
For broader context, see NAPEO, the national PEO industry association.
