PEO Cost in 2026: 2 to 11% of Payroll, or $75 to $250 PEPM
What a Professional Employer Organization actually charges in 2026, the two pricing models, what is bundled in versus billed separately, and the named-provider pricing-model comparison most quotes will land in.
The two PEO pricing models
Almost every PEO quote you receive will use one of two models. The dollar all-in cost on a given headcount and payroll comes out roughly similar between the two, but how the cost scales as you grow is meaningfully different.
Model 1
Percentage of payroll (2% to 11%)
The PEO charges a percentage of total wages paid. Smaller employers (under 25 employees) typically land at 7 to 11 percent; mid-market (50 to 200 employees) negotiates to 3 to 6 percent; large clients commit volume for 2 to 4 percent. Examples of PEOs that commonly quote on this model include ADP TotalSource and Insperity.
Scales with: total payroll. If you give raises or hire higher-paid roles, the PEO fee rises with them.
Model 2
Per-employee per-month ($75 to $250 PEPM)
The PEO charges a flat dollar amount per active employee per month, regardless of that employee's salary. Entry-tier bundles run $75 to $125; full-bundle (including premium HR consulting and benefits administration) runs $150 to $250. Examples of PEOs that commonly quote on this model include TriNet, Justworks, and Sequoia.
Scales with: headcount. Salary increases do not push the PEO fee; new hires do.
For high-salary teams (engineering, finance, biotech), PEPM is structurally cheaper. For lower-salary, higher-headcount teams (retail, services, hospitality), percentage-of-payroll is structurally cheaper. The dominant model in your sector usually reflects which one is cheaper for that workforce profile.
What is bundled in (versus billed separately)
| Service | Usually included | Often billed separately |
|---|---|---|
| Payroll processing + tax filing | Yes | - |
| Direct deposit + W-2 / 1099 issuance | Yes | - |
| Health insurance (medical, dental, vision) | Quoted within bundle (premiums passed through) | Off-cycle plan changes sometimes carry an admin fee |
| 401(k) plan administration | Yes (PEO multiple-employer plan) | Investment menu setup or plan amendments |
| Workers compensation insurance | Yes (PEO master policy) | High-risk class codes may surcharge |
| Unemployment claim handling | Yes | - |
| HR consulting (employee relations, terminations) | Standard hours included | Out-of-scope investigations / litigation support |
| Recruitment / ATS | Sometimes included in premium tier | Usually billed separately or via a partner integration |
| Learning management / training | Rarely in base bundle | Add-on module |
| Per-state registration as the legal employer | Yes for client's existing states | New-state expansion may carry a setup fee |
Inclusion varies materially between PEOs and between bundle tiers within a single PEO. Always get a line-itemed quote, not just a headline percentage or PEPM number.
PEO versus standalone payroll: when does the break-even sit?
Under 25 employees: a PEO is usually cheaper than the assembled stack of standalone payroll (Gusto, Rippling, ADP Run, OnPay) plus a separate small-group health broker plus separate benefits admin. The single biggest driver is health insurance: small-group premiums in most US states run 10 to 25 percent above the equivalent large-group rate a PEO can quote, because the PEO is the co-employer of record across thousands of small businesses.
25 to 100 employees: the break-even sits in this range and depends heavily on (1) average salary, (2) state health insurance market structure, and (3) HR complexity. Companies with high-salary specialised teams skew toward PEPM PEOs (TriNet, Justworks, Sequoia). Companies with broad mid-salary staff skew toward percentage-of-payroll PEOs (ADP TotalSource, Insperity) until they reach 50 to 75 employees, then the maths usually flips toward standalone tools.
100+ employees: standalone modern tools (Rippling, Gusto Plus / Premium, Bamboo HR + Gusto, Workday for the upper end) are usually cheaper on a total-cost basis, with the trade-off being that the company now carries the HR consulting and benefits-broker work in-house or via separate vendors. The financial saving versus a PEO is real but the operational lift on the HR / People team is real too.
Common hidden-cost line items to ask about
- Setup and migration fee. One-time fee for onboarding payroll history, employee data, and benefit elections. Commonly $500 to $5,000 depending on company size.
- Off-cycle payroll runs. Bonus checks, severance payments, final paychecks outside the regular cycle. Often $10 to $50 per off-cycle run.
- State expansion fee. Adding employees in a new state may carry a setup cost while the PEO files as the employer of record in that state.
- High-risk workers comp class. If your workforce includes class codes the PEO master policy flags as elevated risk (construction, roofing, manufacturing), expect a surcharge or even denial of co-employment.
- Termination / exit fee. Leaving a PEO mid-year is contractually awkward; some PEOs charge an exit fee tied to your remaining contract term. Read the off-boarding clause before signing.
