"How much does a PEO cost?" is the first question most business owners ask. The short answer: most businesses pay $40 to $160 per employee per month in admin fees. Some PEOs charge a percentage of your total payroll instead, usually between 2% and 6%.

But admin fees are only part of the picture. Health insurance, workers' comp, and taxes are billed on top. This guide breaks down how PEO pricing actually works, what drives your cost up or down, and how to compare quotes so you know exactly what you're paying for. You can also estimate your PEO costs to see the numbers for your team.

The Short Answer: What Most Businesses Pay in 2026

A PEO (Professional Employer Organization) is a company that partners with your business to handle HR, payroll, and benefits. PEO pricing comes in two forms.

Flat fee (per employee per month): You pay a fixed dollar amount for each employee, every month. The typical range is $40 to $160 per employee per month. Most mid-market businesses land between $100 and $150.

Percentage of payroll: You pay a percentage of your total gross payroll each pay period. The typical range is 2% to 6%, with most PEOs quoting between 3% and 5%.

According to NAPEO's analysis (2019), the average PEO administrative cost across the industry was $1,395 per employee per year, or about $116 per month. That figure is a few years old, and costs have likely risen with inflation. But it gives you a reliable baseline from the industry's own data.

Setup fees are also common. Expect a one-time onboarding charge of $500 to $2,500, though some PEOs waive this for larger clients.

Flat Fee vs. Percentage of Payroll: How Much Does a PEO Cost Under Each Model?

The pricing model your PEO uses can make a big difference in what you pay. Here's how the two models compare:

When salaries riseYour PEO cost stays flatYour PEO cost rises too
Example: 25 employees, $55K avg~$36,000/year (at $120/month)~$55,000/year (at 4%)

Key takeaway: Flat-fee pricing rewards companies with higher salaries. Percentage pricing costs less for lower-paid workforces. Before you compare PEO quotes, ask each provider which model they use.

Note: Some PEOs fold workers' comp and unemployment taxes into their percentage-of-payroll quote. This makes the admin fee look larger than it is. Always ask for a line-by-line breakdown so you can compare apples to apples.

What's Included in the PEO Fee (and What Costs Extra)

Your PEO admin fee typically covers the core services a PEO provides:

  • Payroll processing and tax filing
  • HR support and compliance guidance
  • Employee onboarding paperwork
  • Access to an HR technology platform
  • Basic reporting and analytics

These are the services that make a PEO different from just hiring a payroll company. A PEO handles the administrative side of employment so you can focus on running your business.

Billed separately (pass-through costs):

  • Health insurance premiums. The PEO pools your employees into a larger group to negotiate better rates. But you still pay the premiums. The average employer pays $9,325 per year for a single employee's health coverage, or $26,993 for family coverage (KFF, 2025).
  • Workers' compensation premiums. Based on your industry, state, and claims history. PEOs often get better rates because they pool risk across hundreds of client businesses.
  • State unemployment taxes (SUTA). These vary by state and your company's experience rating.
  • 401(k), dental, vision, life, and disability insurance. If you choose to offer these, the premiums are separate from the admin fee.

The bottom line: The admin fee is your PEO management cost. Insurance and taxes are your employee benefit costs, which you'd pay whether or not you used a PEO. The PEO's job is to get you better rates on those benefits through group purchasing power.

What Affects Your PEO Cost? Six Factors

Not every business pays the same PEO rate. Here's what moves the number:

1. Company size. More employees usually means a lower per-person rate. Pricing often breaks at 25, 50, and 100 employees. A 50-person company typically pays less per head than a 10-person company.

2. Industry. Your workers' compensation class code is the single biggest variable for service-industry and construction businesses. Office workers might pay $0.20 to $0.50 per $100 of payroll in workers' comp. Construction workers could pay $5 to $15 or more per $100 (PeoPayGo, 2026).

3. State. Employment regulations, workers' comp rates, and unemployment insurance costs vary by state. A 10-person team in California typically costs 15% to 25% more than an identical team in Tennessee (eorHQ, 2026).

4. Claims history. Your experience modification rate (EMR) reflects your company's past workers' comp claims. That's a number insurers use to measure your workplace safety track record. A higher EMR means higher premiums. Many PEOs absorb your employees into their master policy, which can help if your EMR is above average.

5. Services bundled. Basic payroll plus compliance sits at the lower end of the range. Full-service PEO with HR support, benefits administration, risk management, and training tools costs more. Some PEOs offer both tiers.

6. Average employee salary. This matters most under percentage-of-payroll pricing. A company where the average salary is $100,000 pays twice as much as one where the average is $50,000, at the same percentage rate.

PEO Cost vs. Hiring In‑House HR

For most companies under 75 employees, a PEO costs significantly less than building an in-house HR team.

Here's the math for a 30-employee company:

PEO route:

  • Admin fee: $100 to $150 per employee per month
  • Monthly cost: $3,000 to $4,500
  • Annual cost: $36,000 to $54,000
  • Includes: payroll, HR support, compliance, benefits admin, risk management

In-house HR route:

  • HR generalist salary: $65,000 to $75,000
  • Benefits and taxes (add 30%): $19,500 to $22,500
  • HR software: $5,000 to $15,000 per year
  • Benefits broker: $3,000 to $5,000 per year
  • Legal and compliance consulting: $5,000 to $10,000 per year

Total in-house cost: roughly $97,500 to $127,500 per year. And with in-house HR, you still don't get the PEO's group buying power on health insurance and workers' comp.

The median HR manager salary in the U.S. is $140,030 per year (BLS, May 2024). The median HR specialist salary is $72,910. For a small business, those salaries alone often exceed what you'd pay a PEO. You can also see how many HR hours a PEO could save you each year.

Do PEOs Actually Save You Money?

The data says yes, for most businesses.

NAPEO's ROI analysis found that PEO clients save an average of $1,775 per employee per year across five cost categories: HR staff, health benefits, workers' comp, unemployment insurance, and external HR services. Against an average admin cost of $1,395 per employee per year, that's a net ROI of 27.2% (NAPEO/McBassi, 2019).

Beyond direct cost savings, PEO clients grow revenue at more than twice the rate of comparable non-PEO businesses. They also have 12% lower employee turnover and are 50% less likely to go out of business (NAPEO/McBassi, 2024).

The savings aren't guaranteed. Businesses with already-low workers' comp rates, strong existing benefits, or efficient in-house HR may see less dramatic returns. The best way to find out is to get actual quotes and compare them to your current costs.

Fees to Ask About Before You Sign

Before you commit to a PEO, get clear answers on these:

  • Early termination fees. Many PEOs charge 25% to 50% of your remaining contract value if you leave early. Some charge flat fees of $2,500 to $5,000 or more.
  • Contract length. Most PEOs require 12 to 36 months. Ask if there's a month-to-month option and what it costs.
  • Auto-renewal clauses. Some contracts automatically renew unless you give 30 to 90 days' notice. Read the fine print.
  • Post-termination fees. Some PEOs charge admin fees for 30 to 90 days after your contract ends to process final payroll, COBRA, and tax filings.
  • Benefits admin fees. A few PEOs charge a separate fee for benefits enrollment and management on top of the admin fee.
  • W-2 and year-end processing. Ask whether year-end tax document processing is included or billed separately.

The most reliable way to compare PEOs is to request a line-item breakdown from at least three providers. Focus on the total cost, not just the admin fee. You can browse PEO providers in our directory to start your search.

The Bottom Line

Most businesses pay $40 to $160 per employee per month in PEO admin fees, or 2% to 6% of payroll. Health insurance, workers' comp, and taxes are billed on top. The total cost depends on your company size, industry, state, and the services you need.

For businesses under 75 employees, a PEO typically costs less than hiring in-house HR while giving you access to better benefits and compliance support. NAPEO data shows a 27.2% net ROI for the average PEO client.
