Book a Free Chat"Our fee is just 4% of payroll." That's the sentence that ends most PEO pricing conversations — and starts most pricing misunderstandings.
PEO fees are layered. There's a base administration fee, workers' comp costs, benefits administration charges, and a growing list of per-service add-ons that many clients discover only after their first invoice. Understanding how the pieces fit together is the only way to make an accurate comparison across providers — or against the cost of handling HR in-house.
This guide breaks down every component of PEO pricing in plain language. No glossy sales framing, no made-up savings claims. Just the structure, how each piece works, and what the numbers actually mean for a business your size.
Why This Perspective Is Different
We're an independent broker. We don't earn more when you choose a more expensive PEO. We earn the same flat referral fee regardless of which PEO you select — which means our job is to help you find the right fit at the right price, not to upsell you on premium tiers.
The Two Core Pricing Models
Nearly every PEO in the market uses one of two administration fee structures. Understanding which model a provider uses — and what it includes — is the foundation of any meaningful cost comparison.
Percentage of Payroll
The most common model. You pay a percentage of your total gross payroll each pay period. Typical range is 2%–12%, with most mid-market PEOs falling between 3%–6% for standard service tiers.
Example
$500,000 annual payroll × 4.5% = $22,500/year in admin fees
Pros
- Fees scale down if you run seasonal payrolls
- Easy to forecast if payroll is stable
Cons
- Fees automatically grow with every raise and bonus
- Can be opaque — percentage applies to which payroll components?
Per Employee Per Month (PEPM)
A flat fee charged per employee per month regardless of salary levels. Typical range is $80–$200 PEPM for bundled HR services, with broader ranges for specialized tiers.
Example
25 employees × $130 PEPM × 12 months = $39,000/year
Pros
- Predictable — doesn't inflate with salary increases
- Easier to budget for growing teams at similar pay levels
Cons
- Fees grow with headcount, not productivity
- PEPM may not include all services you assumed were bundled
Broker Insight: Neither model is inherently better. The right choice depends on your payroll-to-headcount ratio. High-salaried, lean teams often save with PEPM. Lower-wage, larger teams often save with the percentage model. We run the numbers on both before recommending a structure.
What the Base Administration Fee Covers
Most PEO quotes bundle several service categories into the base administration fee. What's included varies considerably by provider and service tier. Here's what you should expect — and what you should ask about explicitly.
Payroll Processing
Typically Included
Direct deposit, payroll runs, W-2 issuance, payroll reporting
Watch For
Off-cycle payroll runs (e.g., corrections, final pay) are often charged separately
Payroll Tax Administration
Typically Included
Federal, state, and local tax withholding, employer tax remittance, Form 941, annual FUTA/SUTA filing
Watch For
Multi-state payroll tax registration fees may be billed as setup charges
HR Administration
Typically Included
Employee handbook templates, onboarding paperwork, HR hotline access
Watch For
Dedicated HR business partner support often requires a premium tier
Compliance Support
Typically Included
ACA reporting (1095-C), FMLA/leave administration guidance, EEO-1 support
Watch For
Hands-on compliance audit assistance may require an add-on engagement
HRIS Platform Access
Typically Included
Employee self-service portal, time and attendance (may require separate module), reporting dashboard
Watch For
Advanced reporting, API access, and custom integrations often carry platform fees
Workers' Compensation: Bundled or Separate?
Workers' compensation is the most variable cost component in PEO pricing — and the one most frequently misrepresented in initial quotes. Some PEOs include workers' comp in the base administration fee. Others quote it separately, typically as a percentage of payroll broken down by job classification code.
When workers' comp is bundled into the admin fee, the headline percentage looks higher but often delivers better value than a PEO that advertises a low admin rate and then prices workers' comp separately at market rates. You need to see both numbers to make a fair comparison.
Apples-to-Apples Comparison Framework
PEO A (bundled)
Admin: 5.5% of payroll
Workers' Comp: Included
5.5% total
PEO B (separate)
Admin: 3.2% of payroll
Workers' Comp: +2.8% separate
6.0% effective
PEO C (PEPM)
Admin: $145 PEPM
Workers' Comp: +$38 PEPM
$183 PEPM effective
*Illustrative figures. Actual rates vary by industry, classification codes, and claims history.
Important: Workers' comp rates within a PEO's master policy are typically much lower than standalone rates for small businesses — sometimes 20%–40% lower, particularly in higher-risk classifications like construction or manufacturing. This savings is real and often justifies the PEO relationship on its own. But confirm the classification codes used in the quote match your actual workforce mix.
Benefits Costs: Administration Fee vs. Premium Passthrough
This is where most business owners get confused — and where some PEO quotes deliberately obscure the true cost. There are two distinct components to benefits costs through a PEO:
1. Benefits Administration Fee
The fee the PEO charges to administer your benefits program — enrollment, carrier coordination, open enrollment management, COBRA notices. This is part of the base PEPM or payroll percentage. Typically $15–$40 per employee per month, often bundled invisibly into the headline rate.
2. Premium Passthrough
The actual cost of the health insurance, dental, vision, and other benefits you offer employees. This is a direct cost passed to you at the PEO's group rate — it is not part of the administration fee. For most employers, this is the largest cost component by a significant margin.
PEO quotes that advertise an impressive administration rate but don't include a benefits premium estimate are showing you an incomplete picture. When you're comparing total cost of ownership, you need the all-in number: admin fee + workers' comp + benefits premium passthrough + employer payroll taxes.
The good news: access to the PEO's group health insurance rates is often where the real financial benefit hides. Small businesses frequently access Fortune 500-level plan designs at rates 15%–35% below what they can obtain independently. That savings often makes the administration fee look very reasonable in context.
The Add-On Charges You Might Not See Coming
Most PEO contracts include a base service bundle — and then a fee schedule for everything outside that bundle. These charges are disclosed, but often in addenda or rate sheets that don't get scrutinized during the buying process.
Setup / Onboarding Fee
$500–$2,000
Charged at contract start. Sometimes waived for larger groups or during promotional periods.
Off-Cycle Payroll Run
$50–$150 per run
Each payroll run outside your normal schedule. Termination pay, corrections, and bonuses often trigger this.
New Hire Onboarding (per employee)
$15–$75 per hire
Some PEOs charge per new hire processed through the HRIS. High-turnover businesses feel this.
Garnishment Processing
$10–$30 per order/month
Each active wage garnishment (child support, IRS levies) processed.
State Tax Registration (new states)
$100–$500 per state
If you expand into a new state, registering with that state's tax authority carries a fee.
401(k) Administration
Add-on PEPM + plan costs
Retirement plan administration is almost always outside the base fee. The PEO may offer plans or facilitate your existing plan.
COBRA Administration
$20–$50 per qualified beneficiary/month
Post-employment COBRA notices and payment processing for former employees.
HR Consulting / Projects
$150–$350/hour
Hands-on HR consulting beyond standard advisory support. Policy drafting, investigation support, reorganization planning.
Enhanced Reporting / BI Access
$50–$200/month
Advanced analytics dashboards, workforce insights, or API data access beyond standard reports.
ACA Compliance Filing
Sometimes included, sometimes not
Confirm explicitly whether 1094/1095-C filing is in the base fee or billed separately.

What this comparison requires: To evaluate whether the PEO cost makes sense, you need to compare this against what you're currently spending on payroll software, benefits brokers, standalone workers' comp, HR consulting, and your own HR staff time. That's the real baseline — not just the admin fee alone.
An independent broker runs this analysis for you, using your actual payroll data and current costs, so you get a genuine apples-to-apples comparison. Our PEO Pricing Guide goes deeper on this methodology.
How an Independent Broker Changes the Pricing Dynamic
PEOs adjust their pricing based on competition. A business owner calling a PEO directly receives the standard retail quote. A broker submitting the same business on behalf of a client receives a competitive quote designed to win against alternatives — and we submit to multiple PEOs simultaneously.
This creates a real market for your account. Providers that know they're competing respond with better rates, tighter fee structures, and more favorable contract terms. Businesses that engage a broker routinely receive quotes 8%–15% below what they'd negotiate alone.
What You Gain with a Broker
- • Multiple competing quotes from vetted PEOs
- • Consistent format for true comparison
- • Pricing for your actual employee count and payroll
- • Fee structure scrutiny (bundled vs. à la carte)
- • Workers' comp classification verification
- • Negotiation leverage — PEOs compete for your business
- • No cost to you — broker fee paid by the PEO
Going Direct Risks
- • One quote, no competitive pressure
- • Different quote formats, impossible to compare
- • Generic quotes not tailored to your workforce
- • Bundled fees hide the actual cost per service
- • Classification errors inflate workers' comp
- • Standard "take it or leave it" contract terms
- • Your time spent managing the entire process
Questions to Ask Every PEO Before Comparing Quotes
Is workers' comp included in the administration fee or quoted separately?
Does the quote assume our current workers' comp classifications, or generic ones?
What is included in the PEPM / percentage rate — specifically list what is NOT included
What are the setup and onboarding fees?
Are off-cycle payroll runs included? What's the per-run charge?
Is 401(k) plan administration included or an add-on? What's the fee?
Is ACA compliance reporting (1094/1095-C) included in the base fee?
What is the charge for adding employees in a new state?
Are COBRA administration costs billed separately or per-event?
What level of HR support is included — general advice line, or dedicated HR business partner?
What does the benefits renewal pricing look like year-over-year historically?
How are mid-year rate adjustments handled and what triggers them?
Key Insight: The PEO that quotes the lowest administration fee is not necessarily the cheapest option. A provider with a 3.8% admin rate but expensive workers' comp, no bundled benefits administration, and a per-hire onboarding charge can cost more annually than a provider quoting 5.2% all-in. Total cost of ownership requires seeing every line item — not just the headline number.
