PEO administrative fees typically run $40 to $160 per employee per month, or 2% to 12% of total payroll — and the industry average admin cost is about $1,395 per employee per year. That fee covers payroll, HR, and compliance only; workers compensation and benefits like health insurance are billed separately on top, and health coverage is often the single largest line item. So comparing PEOs means comparing the all-in cost, not just the headline rate.
This guide breaks down the two pricing models, real 2026 ranges, a worked example, and the hidden fees that change the math. For the variables that move your specific quote, pair it with our breakdown of the 5 factors that impact your PEO cost per employee.
The Two Main PEO Pricing Models
Per Employee Per Month (PEPM)
A flat administrative fee for each employee each month — commonly $40 to $160 per employee, though small teams (under ~15 employees) often see effective rates at the higher end or above because PEOs have account minimums. PEPM is predictable: raises and bonuses don’t automatically increase your admin fee, which makes budgeting easier.
Percentage of Payroll
A percentage applied to gross payroll, typically 2% to 12% (most SMBs land around 3% to 6%). It scales with wages, so it can be efficient for lower-wage teams but gets expensive as salaries, commissions, and overtime climb.
Admin Fee vs. All-In Cost
This is the distinction that trips up most buyers. The PEPM or percentage figure is usually just the administrative fee. Your total invoice also includes:
- Workers compensation — pooled coverage, often billed as a percentage of payroll
- Benefits — health, dental, vision, and retirement, billed as a pass-through (health insurance is frequently 3 to 5 times the admin fee)
- Payroll taxes — collected and remitted by the PEO
- Setup or onboarding fees — one-time charges some providers add
Across the market, all-in cost for SMBs commonly works out to roughly $1,200 to $2,500 per employee per year before benefits pass-through, with the admin portion averaging around $1,395 per employee annually per NAPEO data.
A Worked Example: 10 Employees
Say you have 10 employees averaging $50,000 a year, so your monthly payroll is about $41,667.
- PEPM model — At roughly $150 to $250 per employee for bundled services at this size, you’d pay about $1,500 to $2,500 per month in admin.
- Percentage model — At 3% to 8% of payroll, you’d pay about $1,250 to $3,300 per month.
Both land in a similar range, but the structure matters: if one provider quotes $180 PEPM and another quotes 5% of payroll, convert both to real monthly dollars using your actual payroll before comparing.
Which Model Is Cheaper for You?
A useful rule of thumb based on average wage:
- Average wage above $75,000 — PEPM usually wins, because percentage-of-payroll punishes higher salaries.
- Average wage below $50,000 — percentage-of-payroll often comes out slightly cheaper.
- Variable pay (commissions, overtime, bonuses) — PEPM is more predictable and avoids fee spikes.
The offsetting value is real: pooled workers comp can reduce premiums versus a standalone policy — see how PEO workers comp insurance cuts costs. And if you’re weighing models, our PEO vs. EOR comparison covers a related cost decision.

Hidden Fees That Change the Math
The headline rate rarely tells the whole story. Ask about these before signing, because together they can swing real cost by thousands per employee per year:
- Setup and onboarding fees — one-time implementation charges
- Off-cycle or extra payroll runs — charges beyond your regular schedule
- Workers comp true-ups — year-end reconciliation adjustments
- Benefits renewal increases — annual uplifts on health plans
- Early termination penalties — fees for leaving inside a 12–24 month term
How to Compare PEO Quotes Fairly
- Ask whether pricing is PEPM or percentage of payroll
- Get every line item in writing, in dollars — not a verbal estimate
- Separate the admin fee from pass-through costs (workers comp, benefits)
- Normalize each quote to total annual cost per employee
- Check contract length and early-termination terms
- Compare the all-in cost against your current standalone costs

Frequently Asked Questions
How much does a PEO cost per employee?
Administrative fees commonly run $40 to $160 per employee per month, or 2% to 12% of payroll. The industry average admin cost is around $1,395 per employee per year, with workers comp and benefits billed separately on top.
Is PEPM or percentage-of-payroll cheaper?
It depends on wages. Above about $75,000 average wage, flat PEPM usually wins; below about $50,000, percentage-of-payroll is often slightly cheaper. PEPM is also more predictable for variable pay.
What’s included in the PEO fee?
The admin fee covers payroll, HR support, and compliance. Workers compensation and employee benefits — especially health insurance, often the largest cost — are billed separately as pass-through.
Why do PEO quotes vary so much?
Because cost depends on headcount, industry risk, claims history, benefits selected, average wage, and states of operation. Two same-size businesses in different industries can get very different quotes.
The Bottom Line
A PEO usually costs $40 to $160 per employee per month or 2% to 12% of payroll for administration, plus separately billed workers comp and benefits — averaging roughly $1,200 to $2,500 per employee per year all-in for SMBs. The smart comparison is total annual cost per employee against your current standalone setup, with every line item in writing. Pooled workers comp often offsets a meaningful share of the price.
