A PEO typically costs between $80 and $200 per employee per month, or 2%–12% of total payroll, depending on your company size, industry, and the pricing model your provider uses. Bundled PEOs tend to run $100–$175 PEPM (per employee per month), while unbundled models let you pay only for what you use. The wide range exists because PEO pricing is driven by several variables that most vendors don’t spell out upfront.
If you’re evaluating a PEO for the first time — or comparing quotes you’ve already received — this breakdown gives you the real numbers, the pricing structures to know, and the hidden cost drivers that can quietly inflate your bill.
What Is PEO Pricing and How Does It Work?
PEO pricing is the fee a Professional Employer Organization charges to co-employ your workforce, administer payroll, provide access to group benefits, manage HR compliance, and handle workers’ compensation. It is separate from your actual payroll dollars and benefits premiums — think of it as the service fee layered on top of those hard costs.
There are two dominant pricing structures in the market:
Bundled Pricing (Flat PEPM)
With bundled pricing, you pay a flat dollar amount per employee per month regardless of what services you use. This is the most common model at larger PEOs like Insperity and TriNet. It’s predictable, easier to budget, and often includes a comprehensive suite of services. The tradeoff: you may be paying for HR technology or compliance tools you don’t actually need. Based on our analysis of 40+ PEO providers, bundled fees typically land between $100 and $175 PEPM for companies with 10–100 employees.
Percentage of Payroll Pricing
Some PEOs charge a percentage of your gross payroll instead of a flat fee. This model scales with your payroll spend — which can work in your favor if you have lower-wage employees, but becomes expensive fast as salaries rise. The typical range is 2%–6% of gross payroll for most small and mid-size businesses. For a company with $1 million in annual payroll, that’s $20,000–$60,000 per year just in PEO admin fees.
Unbundled (à la Carte) Pricing
A smaller but growing segment of PEOs — including some tech-forward platforms — offer unbundled pricing where you select and pay only for the modules you need. This works well for companies that already have strong HR infrastructure or only need the PEO for benefits access and payroll. Costs are harder to generalize but often start around $40–$80 PEPM for core payroll and compliance.

PEO Cost Per Employee: Comparison Table by Company Size
PEO cost per employee doesn’t scale linearly — larger headcounts typically command lower per-employee rates due to volume leverage. Here’s how fees generally break down by company size based on our experience matching hundreds of businesses with PEO providers:
| Company Size | Typical PEPM Range | % of Payroll Range | Est. Annual Cost |
|---|---|---|---|
| 2–10 employees | $150–$200 | 5%–12% | $3600 – $34,000 |
| 11–50 employees | $120–$175 | 3%–8% | $72,000–$105,000 |
| 51–150 employees | $100–$140 | 2%–5% | $60,000–$84,000 |
| 151–500 employees | $80–$120 | 2%–4% | Varies significantly |
Note: These are admin/service fees only. Benefits premiums, workers’ comp, and payroll taxes are separate line items billed in addition to the above.
What’s Actually Included in the PEO Fee?
Understanding what the PEO cost per employee covers — and what it doesn’t — is the most important step before comparing quotes. Most bundled PEO fees include the following core services:
Payroll Processing and Tax Administration
Your PEO handles payroll runs, direct deposit, W-2 filing, and federal/state/local payroll tax deposits. According to the IRS, in a PEO arrangement the PEO becomes the employer of record for tax purposes, taking on withholding and remittance obligations that would otherwise sit with you.
Benefits Administration
Access to large-group health, dental, vision, life, and disability plans. This is often where small businesses see the most tangible ROI — a 10-person company can access the same carrier rates as a 5,000-person company. The National Association of Professional Employer Organizations (NAPEO) reports that PEO clients pay 15% less on average for health insurance than comparable non-PEO businesses.
HR Compliance and Risk Management
Employee handbooks, ACA compliance, FMLA administration, state leave law tracking, I-9 verification, and OSHA guidance are typically bundled in. This is where the compliance value compounds for companies operating across multiple states.
Workers’ Compensation
Most PEOs include workers’ comp coverage under a master policy, often eliminating large upfront deposits. The cost is either embedded in the PEPM fee or billed separately as a percentage of payroll per job classification — something to clarify during any demo.
HR Technology Platform
Onboarding, time tracking, PTO management, performance tools, and an employee self-service portal. Platform quality varies significantly — this is one area where PEOs like Gusto and Justworks have historically differentiated themselves on user experience.
The Real PEO Cost Drivers You Need to Know
The five factors below will move your actual quote up or down more than anything else. Understanding them helps you negotiate and compare apples to apples.
1. Industry and Workers’ Comp Risk Class
High-risk industries — construction, manufacturing, healthcare staffing, food service — pay significantly more in workers’ comp premiums, which flows directly into PEO cost. A 20-person construction crew will get a very different quote than a 20-person SaaS company, even with the same employee count.
2. Average Employee Salary
If your PEO uses percentage-of-payroll pricing, higher salaries mean higher fees. A company with $120,000 average salaries paying 4% of payroll is spending nearly twice what a company with $65,000 average salaries pays for the same headcount. This is one reason flat PEPM pricing often makes more sense for professional services firms and tech companies.
3. Benefits Election Rates
The more employees who elect benefits, the higher your total benefits premium spend — but that’s not the PEO’s service fee. What matters here is whether your PEO charges admin markup on benefits (some do). Ask specifically whether the benefits premium you see is net or gross of any PEO margin.
4. Multi-State Complexity
Operating in California, New York, or Washington adds compliance overhead. Some PEOs charge more for multi-state clients or add fees for state-specific filings. If you’re growing across state lines, factor this in when reviewing how larger PEOs like Insperity price their multi-state support.
5. Contract Length and Minimums
Annual contracts typically get lower per-employee rates than month-to-month. Most PEOs require a minimum of 5–10 employees to onboard. Going below your contracted headcount mid-year can trigger minimum fees — always read the termination and true-up clauses.
Hidden PEO Fees That Can Inflate Your Cost
The quoted PEPM is rarely the final number. In our experience matching hundreds of businesses with PEO providers, these are the add-on charges that most commonly surprise buyers after they’ve signed:
- New hire / termination fees: Some PEOs charge $25–$75 per onboarding or offboarding event
- Year-end W-2 fees: Occasionally billed separately at $5–$15 per employee
- Benefits open enrollment fees: Admin charges for running annual enrollment campaigns
- Off-cycle payroll fees: Running a bonus or correction payroll outside the normal schedule can cost $50–$150 per run
- State registration fees: Expanding into a new state mid-contract may trigger a one-time filing fee
- COBRA administration fees: Often charged per qualifying event, not included in base PEPM

Is the PEO Cost Per Employee Worth It?
The ROI question matters more than the sticker price. According to NAPEO research, businesses that use a PEO grow 7–9% faster than comparable non-PEO businesses, have 10–14% lower employee turnover, and are 50% less likely to go out of business. The Department of Labor enforcement environment has also intensified for small employers, making the compliance infrastructure a PEO provides increasingly valuable.
The math typically works like this: if a PEO saves your company one HR compliance penalty, reduces health insurance premiums by 10%, and keeps one $80,000 employee from leaving by improving benefits, the service fee pays for itself several times over. Use our free PEO cost calculator to model the actual numbers for your specific headcount and payroll.
That said, PEOs are not right for every business. Very small companies (under 5 employees), businesses in very low-complexity industries, or companies with strong existing HR infrastructure may find better value staying independent or using a payroll-only solution.

Frequently Asked Questions
How much does a PEO cost per employee per month on average?
A PEO typically costs between $80 and $200 per employee per month in admin fees, with most small and mid-size businesses landing in the $100–$175 PEPM range for a bundled full-service arrangement. Your actual rate depends on your headcount, industry, states of operation, and which pricing model (flat PEPM vs. percentage of payroll) the provider uses.
Is PEO pricing based on employee count or payroll?
PEOs use one of two methods: a flat per-employee-per-month (PEPM) fee, or a percentage of gross payroll (typically 2%–6%). Flat PEPM pricing is more predictable and favors companies with higher average salaries, while percentage-of-payroll models can be cost-effective for businesses with lower-wage workforces. Always ask your provider which model they use before comparing quotes.
What’s not included in a PEO’s per-employee fee?
The PEPM admin fee does not include your actual benefits premiums, payroll taxes, or workers’ compensation premiums — those pass through at cost (or near cost) on top of the service fee. Some PEOs also charge separately for off-cycle payroll runs, new hire onboarding events, and year-end tax filings, so always request a full fee schedule before signing.
At what company size does a PEO make financial sense?
PEOs typically deliver the strongest ROI for companies with 10–150 employees — large enough to absorb the service fee but small enough to benefit from the group buying power on benefits and outsourced HR compliance expertise. Companies under 5 employees may find the minimum fees prohibitive, while companies over 500 often have enough scale to build internal HR infrastructure more cost-effectively.
Can I negotiate PEO pricing?
Yes — PEO pricing is negotiable, especially on PEPM rates, implementation fees, and contract length. Providers have flexibility, and working with an independent broker like PEO Marketplace means you’re bringing competitive quotes to the table, which strengthens your negotiating position. In our experience, buyers who compare 2–3 providers typically save 10%–20% off the first quote they receive.
