Small business owners ask the same question before calling a PEO: how much will this actually cost? The short answer: most small businesses pay $40 to $160 per employee per month for PEO services, or 2% to 12% of gross payroll (NAPEO/McBassi, 2019). But the real number depends on your team size, industry, and which services you need. This guide breaks down PEO costs for small businesses so you can budget accurately and compare proposals on equal terms.
What Small Businesses Actually Pay
The average annual PEO cost is $1,395 per employee (NAPEO/McBassi, 2019). That works out to roughly $116 per employee per month.
But averages hide a wide range. A 10-person accounting firm with low-risk jobs and basic payroll might pay $60 per employee per month. A 30-person construction company with high workers’ comp rates and full benefits administration might pay $180 or more.
Two pricing models shape these numbers. Flat-rate pricing charges a set dollar amount per employee per month (PEPM). That is the most common structure for small businesses under 50 employees, and it typically runs $40 to $160 PEPM. Percentage-of-payroll pricing takes 2% to 12% of your total gross payroll each period. For a deeper look at how these models work, see our guide to PEO pricing models.
What Is Included in Your PEO Cost
PEO fees cover a bundle of services that most small businesses would otherwise buy separately. Here is what a typical PEO cost includes:
- Payroll processing and tax filing (calculating pay, withholding taxes, filing quarterly and annual returns)
- Workers’ compensation insurance (coverage that pays employees if they get hurt on the job)
- HR compliance support (help following federal, state, and local employment laws)
- Benefits administration (enrolling employees in health, dental, vision, and retirement plans)
- Employee self-service portal (a website where employees view pay stubs and manage benefits)
- Unemployment claims management (handling claims when employees leave)
Not every PEO includes all of these in the base price. Some charge separately for benefits administration or 401(k) plans. If you are still learning what a PEO is, start there first. For a full list of services, see what a PEO does.
Five Factors That Drive Your PEO Cost
Your quoted PEO price comes down to five things.
1. Employee count. More employees usually means a lower per-person rate. PEOs give volume discounts because their fixed costs spread across a larger group (ADP, 2026). A 50-person company often pays $10 to $30 less per employee per month than a 10-person company.
2. Industry and risk level. Workers’ comp insurance is priced by job type. Low-risk office jobs cost $0.20 to $0.50 per $100 of payroll. High-risk construction or manufacturing jobs cost $5 to $15 per $100 (PEOPayGo, 2026). This single factor can swing your total cost by thousands per year.
3. Average salary. Percentage-of-payroll pricing means higher wages equal higher PEO costs. A company with an average salary of $80,000 pays more than one averaging $40,000 under the same percentage rate.
4. Location. State unemployment tax (SUTA) rates vary from under 1% to over 5% depending on your state and claims history. Workers’ comp rates also vary by state.
5. Services selected. Adding health insurance, 401(k) plans, or specialized HR consulting raises the total. Companies that only need payroll and basic compliance pay less.
Use our PEO cost calculator to estimate your specific costs based on these factors.
PEO Costs by Company Size
| Factor | 5 to 15 Employees | 16 to 49 Employees | 50 to 150 Employees |
|---|---|---|---|
| Typical admin fee (PEPM) | $100 to $200 | $75 to $150 | $40 to $100 |
| Annual admin cost per employee | $1,200 to $2,400 | $900 to $1,800 | $480 to $1,200 |
| Negotiating power | Low | Moderate | Strong |
| Benefits access | Group plans through PEO | Better rate leverage | Competitive with direct plans |
| Setup complexity | Simpler onboarding | Standard | More complex, potential volume discount |
Ranges reflect industry averages. Actual costs vary by industry, state, and services selected.
Smaller businesses pay more per employee because the PEO’s fixed costs (setup, compliance review, account management) spread across fewer people. As your team grows, the per-person cost drops.
For a concrete example: a 10-person company paying $150 PEPM spends $18,000 per year on PEO admin fees. A 50-person company paying $80 PEPM spends $48,000 total, but only $960 per employee per year. That is roughly 40% less per head.
The savings story also changes with size. The average ROI of working with a PEO is 27.2%, meaning a business that spends $1,395 per employee saves roughly $1,775 per employee through lower insurance costs, reduced turnover, and avoided compliance penalties (NAPEO/McBassi, 2019).

Hidden Costs to Watch For
The monthly admin fee is only part of the picture. These charges show up in many PEO contracts but rarely appear in initial quotes:
- Setup fees: $500 to $2,500 for onboarding, depending on your employee count and how organized your existing records are (TriNet, 2026).
- Early termination penalties: many PEO contracts run 12 to 36 months with auto-renewal clauses. Leaving early can cost two to six months of fees.
- Benefits markups: some PEOs add 5% to 20% on top of health insurance premiums without listing it as a separate charge (Helpside, 2026).
- Workers’ comp true-ups: if your actual payroll differs from the estimate, you owe the difference at year-end.
- Per-event fees: charges for each new hire ($25 to $150), garnishment processing, or off-cycle payroll runs.

How to Lower Your PEO Cost
You cannot change your industry or state, but you can control how you buy PEO services.
Compare at least three proposals. PEO pricing varies significantly between providers. Getting multiple quotes lets you benchmark each cost component.
Ask every provider to itemize costs. Even if one quotes bundled pricing, request an itemized breakdown so you can compare on equal terms. Our guide to PEO cost per employee shows how to calculate your true all-in cost.
Negotiate the admin fee. The admin fee is the PEO’s margin. Companies with 20 or more employees, clean payroll history, and low workers’ comp claims have negotiating room.
Review benefits separately. Ask whether the PEO’s health insurance rate beats what you could get independently. Compare the PEO’s plan to a standalone small group plan through an insurance broker.
Use a PEO broker. Brokers compare multiple PEOs on your behalf at no cost to you. PEO providers pay brokers directly, so the service costs you nothing. Our PEO directory can help you see which providers serve your area.
The Bottom Line
PEO costs for small businesses range from $40 to $160 per employee per month, with the average landing around $116. Your exact price depends on your team size, industry, location, and which services you select.
The real question is not just what a PEO costs, but what it saves you: lower insurance premiums, reduced compliance risk, and fewer hours spent on HR administration. Use our PEO ROI calculator to see if the math works for your business.
