PEO Administrative Fee Comparison Guide

When a PEO sends you a proposal, the admin fee is usually the first number you see. It looks simple: $100 or $150 per employee per month. But that number alone does not tell you what you are actually paying for, what is billed separately, or how the fee compares to what other businesses your size are paying.

The PEO administrative fee is the cost of the PEO’s core services: payroll processing, tax filing, HR support, and compliance monitoring (making sure you follow federal, state, and local employment laws). It does not include health insurance premiums, workers’ compensation premiums, or retirement plan contributions. Those are separate pass-through costs that often make up the majority of your total PEO bill.

This guide breaks down what the admin fee covers, what it does not, how fees compare by company size, and how to evaluate proposals so you are comparing the same thing across providers. If you are still learning what a PEO is, start there first.

What Is a PEO Administrative Fee?

The PEO administrative fee is the price the PEO charges to handle your HR, payroll, and compliance work. Think of it as the management fee for outsourcing your back-office HR functions. It is quoted in one of two ways:

• Per-employee-per-month (PEPM). A flat dollar amount for each active employee on your roster. If you have 20 employees and the fee is $120 PEPM, you pay $2,400 per month regardless of what those employees earn.
• Percentage of gross payroll. A percentage of your total wages each pay period. If the rate is 4% and your monthly payroll is $200,000, you pay $8,000 that month. As wages, overtime, or headcount increase, the dollar amount goes up.

The NAPEO-cited industry average admin fee is $1,395 per employee per year, which works out to roughly $116 per employee per month (NAPEO/McBassi, 2019). But averages hide a wide range. A 10-person company typically pays more per employee than a 200-person company because PEOs offer volume discounts. For a detailed breakdown of the two models, see our guide to PEO pricing models.

What Is Included in the Admin Fee

The admin fee should cover all of these core services. If a PEO charges extra for any of them, that is a red flag worth questioning.

• Payroll processing (weekly, biweekly, or semimonthly pay runs)
• Federal, state, and local tax filing and remittance
• W-2 production and year-end reconciliation
• New hire reporting to state agencies
• I-9 compliance (verifying employees are authorized to work in the US)
• Multi-state tax registration and maintenance
• HR technology platform (employee self-service portal, document storage)
• HR compliance support (handbook development, policy updates, employment law guidance)
• Unemployment claims management (contesting unjustified claims on your behalf)
• Benefits enrollment administration (processing enrollments, changes, and terminations)

This is the work the PEO does for you. For a more detailed look at what a PEO handles, see our breakdown of PEO services.

What Is Not Included: Pass‑Through Costs

The admin fee is only one piece of your total PEO bill. The rest are pass-through costs that the PEO collects and forwards to insurance carriers, government agencies, and plan administrators. These are real costs, but they are not the PEO’s fee for its services.

Health, dental, and vision insurance premiums. The actual carrier premiums for your employees’ coverage. These are typically the largest line item on your PEO bill. Some PEOs route coverage through a master health plan and apply a markup of 5% to 20% on premiums without disclosing it separately. Always ask whether premiums are billed at carrier net cost.

Workers’ compensation premiums. Priced by your industry classification code and claims history. A tech company might pay $0.15 per $100 of payroll. A landscaping company might pay $5.00 per $100. Some PEOs include workers’ comp in the base admin fee. Others quote it separately. Either way, get the rate per $100 of payroll by job code in writing.

Employer FICA taxes. Social Security (6.2%) and Medicare (1.45%) taxes are a statutory cost. The PEO collects and remits them, but they are not a PEO fee.

Retirement plan contributions. Any 401(k) match or profit-sharing payments are pass-through. Plan administration (recordkeeping and compliance testing) is sometimes included in the admin fee and sometimes quoted separately at $4 to $8 per employee per month.

The distinction matters because a PEO quoting "$200 PEPM" and one quoting "$120 PEPM plus separate workers’ comp" might cost the same once you add everything up. For more on costs that can catch you off guard, see our guide to hidden PEO fees.

PEO Administrative Fees by Company Size

Admin fees are not one-size-fits-all. PEOs offer volume discounts, so the per-employee cost drops as your headcount grows. Here is how fees typically break down by company size.

A 20-employee marketing agency paying $140 PEPM is within range. A 20-employee company paying $220 PEPM should ask what is driving the premium or get a competing bid. Use our PEO cost calculator to estimate where your company falls.

How to Compare PEO Admin Fee Proposals

Comparing PEO proposals is harder than it looks. Different providers bundle costs differently, so a lower headline fee might not mean a lower total cost. Here is how to make a fair comparison.

Step 1: Separate the admin fee from pass-through costs. Ask each provider to break their quote into three lines: admin fee, insurance premiums (health + workers’ comp), and all other charges. This is the only way to compare the actual cost of the PEO’s services.

Step 2: List every per-event charge. Request the full fee schedule. Look for setup fees ($250 to $2,500), per-hire onboarding charges ($25 to $150), termination processing fees ($50 to $200), COBRA administration ($50 to $100 per participant per month), and ACA reporting fees ($200 to $500 per year). These add up.

Step 3: Ask about benefits markup. Ask each provider in writing: "Are health insurance premiums billed at carrier net cost, or is there a markup?" Some PEOs apply a 5% to 20% markup on premiums through their master plan without disclosing it as a separate line item.

Step 4: Calculate total annual cost per employee. Add the admin fee, all per-event charges (estimate based on your turnover rate), and any benefits markup. Divide by employee count. This gives you a true apples-to-apples number.

Step 5: Negotiate. PEO admin fees are negotiable at most providers. Running a competitive process with two or three proposals typically produces 8% to 15% reductions from initial quotes. You can also negotiate annual rate-increase caps (aim for 3% to 5%) and waived setup fees.

PEPM vs. Percentage of Payroll: Which Model Is Cheaper?

Neither model is always cheaper. The right choice depends on your average employee salary.

PEPM works better when average salaries are high. If your employees average $80,000 or more per year, a flat PEPM fee keeps your admin cost steady regardless of wages. A 4% payroll fee on $80,000 is $3,200 per employee per year. A $130 PEPM fee is $1,560 per year. The difference is significant.

Percentage of payroll works better when wages are low. A warehouse with employees averaging $35,000 per year would pay $1,400 at 4% of payroll, compared to $1,560 at $130 PEPM. The percentage model also adjusts automatically as employees come and go, which simplifies billing for businesses with seasonal headcount swings.

One thing to watch with percentage pricing: overtime, bonuses, and raises all increase your PEO cost immediately. With PEPM, your fee only changes when headcount changes. Our PEO savings calculator can help you model both scenarios.

Factors That Affect Your Admin Fee

Your quoted admin fee depends on several variables:

• Employee count. More employees means a lower per-person rate. A 50-employee company typically pays 20% to 30% less per employee than a 10-employee company.
• Industry and risk classification. Higher-risk industries (construction, healthcare, transportation) pay more because the PEO takes on greater compliance and insurance exposure.
• Geographic complexity. Multi-state employers pay more than single-state businesses. Each additional state adds compliance requirements. Employers in California, New York, and Massachusetts face higher fees due to stricter labor laws.
• Services selected. A basic payroll and compliance package costs less than a full suite with health insurance, dental, vision, 401(k), and employee assistance programs. More services mean a higher admin fee.
• Contract length. Longer commitments (two or three years vs. month-to-month) can reduce admin fees by 5% to 10%.

Understanding these variables helps you evaluate whether a quote is competitive or inflated. You can estimate what a PEO saves you on time alone with our time savings calculator.

Common Admin Fee Mistakes to Avoid

Comparing headline rates without matching scope. A PEO quoting $90 PEPM that excludes workers’ comp, benefits admin, and COBRA charges is not cheaper than one quoting $140 PEPM that includes all of those. Always compare total annual cost per employee.

Ignoring renewal increases. The first-year admin fee is often a promotional rate. Ask about renewal pricing in writing. Annual increases of 8% to 15% are common in the industry. If the contract does not cap increases, your Year 3 fee could be 25% to 35% higher than Year 1.

Missing early termination penalties. Most PEO contracts run 12 to 36 months with automatic renewal. Early exit can trigger penalties equal to two to six months of fees or 10% to 25% of the remaining contract value. Read the termination clause before signing.

Skipping the fee schedule review. The master service agreement includes a fee schedule attachment listing every billable event. Review it line by line. Common surprises: per-hire charges, offboarding (processing when someone leaves your company) fees, mid-year rate adjustment clauses, and post-termination billing for 60 to 90 days after you leave the PEO.

The Bottom Line

The PEO administrative fee is what you pay for the PEO’s core services. It typically ranges from $40 to $200 per employee per month, with the exact amount depending on your company size, industry, location, and the services you select. The industry average is $1,395 per employee per year (NAPEO/McBassi, 2019).

The admin fee is not your total PEO cost. Health insurance, workers’ comp, and retirement contributions are separate. To compare proposals fairly, separate the admin fee from pass-through costs, list every per-event charge, and calculate the total annual cost per employee. Whether the PEO saves you money overall depends on what you are currently spending on HR, insurance, and compliance. You can run the full calculation with our PEO ROI calculator.
