PEO Cost Per Employee: What You Actually Pay in 2026
How much does a PEO cost? Average is $1,395/employee/year. Full pricing breakdown, hidden fees, and PEO vs HR software cost comparison.
PEO Cost Per Employee
What small businesses actually pay in 2026
When I started looking into PEOs for my 12-person company, every provider told me the same thing: "Let us put together a custom quote." Three weeks and six sales calls later, I had quotes ranging from $87 to $172 per employee per month, with no clear explanation for why one PEO cost twice as much as another. The pricing felt designed to confuse.
After evaluating three PEOs and running the numbers against alternative setups, I learned that PEO pricing is not mysterious. It follows predictable patterns, includes costs that are often not disclosed upfront, and for many small businesses under 25 employees, costs significantly more than assembling an HR stack from standalone tools. The problem is that PEOs benefit from opacity: if you do not know the typical price range, you cannot tell whether a quote is competitive.
This guide breaks down exactly what PEOs cost in 2026: the average price per employee, the two main pricing models (per-employee and percentage-of-payroll), what major PEOs actually charge, the hidden fees that inflate the real cost, and a direct comparison between PEO costs and the cost of using HR software instead. At FirstHR, we built an HR platform for small businesses specifically because the PEO model did not make economic sense for companies with 5 to 25 employees that did not need co-employment or pooled benefits.
Average PEO Cost Per Employee
The most widely cited figure comes from NAPEO (National Association of Professional Employer Organizations): the average PEO cost is $1,395 per employee per year. This translates to approximately $116 per employee per month. However, this average masks significant variation based on the PEO, the services included, and the client's industry and location.
| Metric | Low End | Average | High End |
|---|---|---|---|
| Monthly cost per employee (PEPM) | $40 | $116 (NAPEO avg) | $160+ |
| Annual cost per employee | $480 | $1,395 (NAPEO avg) | $1,920+ |
| Percentage of payroll | 2% | 5-7% | 12% |
| Annual cost for 10 employees | $4,800 | $13,950 | $19,200+ |
| Annual cost for 25 employees | $12,000 | $34,875 | $48,000+ |
| Annual cost for 50 employees | $24,000 | $69,750 | $96,000+ |
PEO Pricing Models Explained
PEOs use four pricing approaches. Understanding which model a PEO uses is essential for comparing quotes accurately, because a $100 PEPM quote and a "6% of payroll" quote can represent very different annual costs depending on your average salary.
The practical difference: for a 10-employee company with $600,000 total annual payroll ($60,000 average salary), a 6% of payroll model costs $36,000 per year ($300 PEPM equivalent). A $100 PEPM model costs $12,000 per year. The same 10 employees, but 3x the price. The percentage model penalizes companies with higher-paid employees.
What Major PEOs Actually Charge
Most PEOs do not publish pricing. They require a custom quote based on your headcount, industry, location, and benefits needs. The table below combines published pricing (where available) with ranges from public sources, broker disclosures, and user reports.
| PEO | Pricing Model | Published Price | Estimated Range | Minimum Employees |
|---|---|---|---|---|
| Justworks | PEPM (published) | $59/emp/mo (Basic), $109/emp/mo (Plus) | $59-$109 PEPM | 2 |
| ADP TotalSource | Custom quote | Not published | $100-$160+ PEPM (estimated) | 5-10 |
| TriNet | PEPM or % payroll | Not published (example: $150 PEPM) | $100-$150 PEPM (estimated) | 5 |
| Insperity | Custom quote | Not published | $100-$150 PEPM (estimated) | 5-15 |
| Large national PEO (A) | Custom quote | Not published | $80-$140 PEPM (estimated) | 5-10 |
| HR platform with PEO add-on | PEPM | Base HR fee + PEO add-on | $60-$120+ PEPM (estimated total) | 1 |
| CoAdvantage | % payroll | Not published | 4-8% of payroll (estimated) | 5 |
| Amplify PEO | PEPM | Not published | $80-$130 PEPM (estimated) | 5-10 |
The pricing opacity is deliberate. PEOs customize pricing based on your risk profile (industry, claims history, state), which means the same PEO charges different rates to different clients for the same services. This makes direct comparison difficult without requesting multiple quotes, which is the PEO sales process by design.
How to Read a PEO Quote and Compare Two of Them
A PEO invoice is not a price. It is your entire cost of employment run through one bill: gross wages, employer payroll taxes, workers compensation premium, benefits premiums, and somewhere inside it, the fee the PEO actually charges for its services. Two quotes are comparable only after you separate the money the PEO keeps from the money it passes through.
| Line item | Who sets the number | Negotiable? |
|---|---|---|
| Gross wages | You. This is your own payroll and belongs in neither quote. | N/A - strip it out before comparing |
| Employer FICA (6.2% Social Security up to the annual wage base, 1.45% Medicare with no cap) | Federal law. Identical at every PEO. | No. If one quote shows a higher FICA figure, the quotes are built on different payroll assumptions. |
| FUTA and state unemployment | Federal and state law, but the rate applied depends on whose unemployment account the wages are reported under. | Rarely, but ask which account is used and at what rate - this is where quotes diverge most quietly. |
| Workers compensation premium | The PEO's carrier, based on your class codes and payroll. | Partly. Class code assignment is worth auditing; a misassigned code moves the number substantially. |
| Benefits premiums | The carrier, plus whatever the PEO adds before billing you. | The plan design is negotiable, the carrier rate is not, and the markup is negotiable only if you ask what it is. |
| Administrative fee | The PEO. This is the actual product you are buying. | Yes. This is the line to push on, and often the only one. |
The normalization exercise takes ten minutes and changes decisions. Take a 12-person company with $780,000 in annual payroll. PEO A quotes $149 per employee per month, described as all-inclusive: 12 employees times $149 times 12 months is $21,456 a year. PEO B quotes 4% of payroll, which is $31,200. A looks 31% cheaper. Then you read the fine print and find that B's 4% includes the workers compensation premium while A bills it separately at 1.2% of payroll, or $9,360. A's real total is $30,816. The gap between the two quotes is not 31%. It is 1%.
Three questions force the comparison into the open. First: which of these line items are inside the quoted number and which are billed on top? Second: what is the administrative fee alone, expressed as a dollar figure per employee per month? Third: what does this quote assume about my payroll and headcount, and what happens to the price if either changes by 20%? A PEO that will not answer the second question in writing is quoting a bundle you cannot audit, which is a fair reason to keep shopping.
Hidden PEO Costs Most Quotes Do Not Include
| Hidden Cost | Typical Range | When You Pay It |
|---|---|---|
| Setup / implementation fee | $500-$5,000 | Upfront, before services begin |
| Benefits markup | 5-20% above the PEO's negotiated group rate | Monthly, embedded in your benefits invoice |
| Workers comp audit adjustment | Varies (can be $1,000-$10,000+) | Annually, after year-end payroll audit |
| Early termination fee | 30-90 days of fees, or per-employee penalty | When you leave before contract end |
| Off-cycle payroll fee | $25-$75 per run | Each time you run payroll outside the regular schedule |
| Year-end reporting / W-2 fee | $5-$25 per employee | Annually, at tax filing time |
| State registration fees | $100-$500 per state | When adding employees in new states |
| COBRA administration fee | $25-$50 per qualifying event | When employees leave |
| Benefits renewal increase | 5-15% annual increase | At plan renewal (often non-negotiable) |
The hidden costs that affect small businesses most: benefits markup and workers comp audit adjustments. The benefits markup is invisible because the PEO presents "your" health insurance rate without disclosing how much they added on top of the insurer's rate. Workers comp audit adjustments surprise employers at year-end when the PEO reconciles estimated payroll (used to calculate premiums at the start of the year) against actual payroll. If actual payroll was higher, you owe the difference. Research from the Work Institute shows that 20% of turnover happens within the first 45 days; for PEO clients, each departure triggers COBRA administration fees on top of the regular PEO cost.
What Affects PEO Pricing
| Factor | How It Affects Price | Impact |
|---|---|---|
| Number of employees | More employees = lower PEPM (volume discount). Most PEOs offer better rates at 25+, 50+, 100+. | High |
| Industry | High-risk industries (construction, manufacturing, healthcare) pay more due to workers comp and liability exposure. | High |
| Location (state) | States with higher workers comp rates, mandated benefits, or complex employment law cost more. | Medium-High |
| Benefits package | More comprehensive benefits (PPO vs HDHP, dental, vision, 401k match) increase cost significantly. | High |
| Average employee salary | For percentage-of-payroll PEOs, higher salaries = higher costs regardless of headcount. | High (%-model only) |
| Claims history | Prior workers comp claims, unemployment claims, or health insurance claims raise your risk profile. | Medium |
| Contract length | Multi-year contracts may offer lower rates but include termination penalties. | Low-Medium |
| Services included | Bundled PEOs cost more; some offer modular pricing where you select only what you need. | Medium |
The factor most small businesses underestimate: benefits package. For a 10-person company, the difference between a bronze-level HDHP and a gold-level PPO through a PEO can be $3,000 to $6,000 per employee per year. That is $30,000 to $60,000 in annual cost difference for the same 10 people with the same PEO.
The Payroll Tax Mechanics Behind the Price
The single largest one-time cost of a PEO relationship is usually not in the quote at all. It comes from the way employment taxes are attributed when your employees move onto, and later off of, the PEO's tax reporting. Whether that cost lands on you depends on one distinction most sales calls never raise.
Certification also governs whether the annual wage bases restart mid-year. Social Security tax applies to each employee's wages only up to an annual wage base, and unemployment taxes apply only to the first several thousand dollars of wages, so both stop for high earners partway through the year. When employees move to a CPEO mid-year, successor-employer treatment carries the year-to-date wages across and nothing restarts. When the arrangement does not qualify for that treatment, the clock can reset: the same employee is treated as starting fresh, and the 6.2% Social Security tax resumes on wages that already cleared the base once.
Unemployment tax behaves the same way with smaller numbers on the federal side and larger ones on the state side. FUTA is 6.0% on the first $7,000 of each employee's wages, offset by a credit of up to 5.4% for timely state unemployment payments, which puts the usual net cost at 0.6%, or about $42 per employee per year. A restart of that base is a rounding error. State unemployment is not: state taxable wage bases run from $7,000 in some states to several times that in others, and the rate applied depends on whose account the wages are reported under. Ask directly whether your wages are reported under the PEO's state account or under your own client-level account. Many states require client-level reporting for exactly this reason, but the answer varies by state and by PEO.
That answer matters on the way out as well as on the way in. If your favorable experience rating sat dormant under the PEO's account for three years, the rate you get when you leave may be the state's new-employer rate rather than the rate you earned before you joined. Confirm the rule in each state where you have employees before you sign, not when you are drafting the termination notice. One more item worth confirming: certification also determines whether payroll-based tax credits, including the Work Opportunity Tax Credit and the payroll-tax offset some companies claim for research activity, are computed at your company level rather than lost inside the PEO's aggregate filings.
PEO Cost vs HR Software Cost: The Comparison No One Shows You
PEO marketing compares PEO costs to the cost of hiring a full-time HR manager ($75,000 to $120,000 per year). This comparison is misleading for small businesses under 25 employees because the real alternative is not a full-time HR hire. It is HR software plus standalone payroll plus a benefits broker. That combination costs 60 to 80% less than a PEO for companies that do not need co-employment or pooled benefits.
| Component | PEO Cost (10 Employees) | HR Software Stack (10 Employees) |
|---|---|---|
| HR administration (onboarding, documents, HRIS, compliance) | Included in PEPM (est. $30-$60 of the $100-$160) | $98/month flat ($1,176/year) |
| Payroll processing and tax filing | Included in PEPM | $40-$80/month + $6/employee ($1,200-$1,680/year) |
| Benefits administration | Included (but marked up 5-20%) | Benefits broker (typically commission-based, $0 direct cost) |
| Workers compensation insurance | Included (bundled, often marked up) | Direct carrier policy ($2,000-$8,000/year depending on industry) |
| HR compliance guidance | Phone/email support line included | Quarterly attorney consultation ($200-$600/quarter) |
| Co-employment (shared liability) | Included (core PEO value) | Not available (employer retains full liability) |
| Total annual cost (10 employees) | $12,000-$19,200 | $5,200-$12,400 |
| Cost per employee per year | $1,200-$1,920 | $520-$1,240 |
The critical distinction: a PEO bundles everything (HR, payroll, benefits, workers comp, compliance) into one contract with one provider. An HR software stack separates each component, letting you choose the best provider for each function and avoid paying for services you do not need. The trade-off is that you manage multiple vendors instead of one. For a 10-employee company where the founder handles HR, the HR software stack saves $6,800 to $7,960 per year. That is the salary of a part-time employee.
When a PEO Is Worth the Cost
| Scenario | Why PEO Makes Sense | Typical Savings vs Alternative |
|---|---|---|
| You need group health insurance but cannot get good rates as a small employer | PEOs pool thousands of employees to negotiate large-group rates. For companies with 5-20 employees, PEO health plans can be 10-30% cheaper than small-group market rates. | Net savings after PEO admin fees |
| You are in a high-risk industry (construction, manufacturing) | PEOs provide workers comp through their master policy, often at lower rates than individual small-business policies due to pooled risk. | 15-40% lower workers comp premiums |
| You operate in states with complex employment law (CA, NY, MA) | PEO compliance teams stay current on state-specific requirements. The cost of non-compliance (lawsuits, penalties) can exceed PEO fees. | Risk mitigation, not direct savings |
| You are scaling rapidly (hiring 5+ people per quarter) | PEOs handle onboarding, benefits enrollment, and payroll setup for each new hire. At high hiring velocity, the admin time savings justify the cost. | 20-30 hours of admin time per quarter |
| You want one vendor for everything (simplicity over cost) | One contract, one invoice, one support team. Reduces vendor management complexity. | Time savings, not cost savings |
The common thread: PEOs are worth the cost when you need something you cannot get on your own (large-group benefits rates, pooled workers comp) or when the complexity of your situation (multi-state, high-risk, rapid scaling) justifies paying for expert compliance support. For a stable 10-person company in a low-risk industry with employees in one state, the PEO's core value proposition (co-employment, pooled insurance) may not apply.
When HR Software Costs Less Than a PEO
| Scenario | Why HR Software Wins | Cost Difference |
|---|---|---|
| You have 5-25 employees in a low-risk industry | PEO admin fees exceed the value of services used. HR software handles the admin at 60-80% less. | $6,000-$15,000/year saved |
| You already have a payroll provider you like | Switching payroll to a PEO creates lock-in. Keeping your payroll + adding HR software avoids the switch. | No transition cost |
| You do not need group health insurance (QSEHRA or no benefits) | PEO benefits pooling has no value if you are not using group insurance. You pay admin fees for a service you do not use. | $3,000-$8,000/year saved on benefits markup |
| Your workers comp rate is already low | Low-risk industries (tech, professional services) get competitive workers comp directly. PEO pooling does not help. | $500-$3,000/year saved |
| You want pricing transparency | HR software publishes pricing ($98-$198/month flat). PEOs require custom quotes and do not disclose breakdowns. | Predictable budget vs opaque invoices |
| You are leaving a PEO | Transition to HR software + standalone payroll eliminates co-employment and reduces annual cost. | $5,000-$15,000/year saved after transition |
Organizations with strong onboarding see 82% better retention (Gallup). The quality of onboarding does not depend on whether you use a PEO or HR software. It depends on whether onboarding is structured with clear tasks, deadlines, and accountability. Both PEOs and HR software can deliver structured onboarding. The difference is cost: the PEO charges $100+ per employee per month for onboarding as one of many bundled services. HR software charges $98 per month total for onboarding as the core product.
What It Actually Costs to Leave a PEO
The exit is where the true price of a PEO becomes visible, because everything the PEO was holding on your behalf has to be rebuilt in your own name at the same time. The fees in the contract are the smallest part of it. The sequencing is the expensive part.
| What has to move | The trap | How to avoid it |
|---|---|---|
| Notice under the contract | Many agreements auto-renew unless written notice lands inside a defined window before the anniversary date. | Diary the notice window when you sign, not when you decide to leave. |
| Health plan | Leaving mid-plan-year restarts deductibles and out-of-pocket maximums under the new carrier, which employees experience as a pay cut. | Time the exit to the plan year, or negotiate deductible credit with the incoming carrier as a condition of placing the group. |
| 401(k) | PEO plans are usually multiple employer plans. How your account balances move determines whether employees can take distributions, and the answer is usually no. | Decide early whether you are spinning the assets into a new plan of your own or terminating participation, and get the answer in writing from both recordkeepers before the exit date. |
| Workers compensation | The PEO's master policy stops covering you the day you leave, and your claims history sat under their policy, so you may have no experience modification of your own. | Bind your own policy effective the exit date and ask the PEO in writing for the loss runs attributable to your employees. |
| COBRA | Former employees who elected COBRA under the PEO's plan do not disappear when you leave. | Assign responsibility for existing qualified beneficiaries in writing. If the PEO's plan stops covering them and you maintain another group health plan, the obligation can land on your plan. |
| Unemployment and tax accounts | You may need your own state unemployment and withholding accounts in every state where you have employees, and registration is not instant. | Start registrations 60 to 90 days out. In some states, an account number takes weeks. |
Two dates make the whole thing manageable. The first is January 1, which avoids the wage base reset described above and lines up with most plan years. The second is 60 to 90 days before that, which is when the new payroll provider, the new benefits carrier, and the state account registrations all need to be in motion. A company that decides in November to leave on January 1 is not leaving on January 1.
Budget the transition itself in the range the exit fees suggest, but treat the recoverable items as the real prize: the administrative fee you stop paying, the benefits markup you stop paying, and the workers compensation premium you can now shop on your own class codes. For a 25-person company, those three together are usually a five-figure annual number, which is why the transition cost pays for itself inside the first year even in the least favorable case.
Total Cost Comparison: PEO vs HR Software Stack
| Employees | PEO Annual Cost (at $100 PEPM) | HR Software Stack Annual Cost | Annual Savings |
|---|---|---|---|
| 5 | $6,000 | $3,200-$4,800 | $1,200-$2,800 |
| 10 | $12,000 | $4,200-$6,400 | $5,600-$7,800 |
| 15 | $18,000 | $5,300-$8,000 | $10,000-$12,700 |
| 25 | $30,000 | $7,400-$12,000 | $18,000-$22,600 |
| 50 | $60,000 | $11,200-$19,000 | $41,000-$48,800 |
The cost gap widens with every hire. A PEO charges more per employee added. HR software on a flat-fee model charges the same whether you have 10 employees or 50. At 50 employees, the PEO costs $60,000 per year while the HR software stack costs $11,200 to $19,000. The $41,000 to $48,800 annual difference is the cost of a full-time employee. SHRM recommends evaluating PEO cost against alternatives annually, as the cost-benefit balance shifts as companies grow and their HR needs evolve.
Frequently Asked Questions
How much does a PEO cost per employee?
The average PEO cost is $1,395 per employee per year according to NAPEO (National Association of Professional Employer Organizations). Monthly costs range from $40 to $160 per employee per month (PEPM) or 2% to 12% of total payroll, depending on the PEO, services included, industry, location, and number of employees. For a 10-employee company with average salaries, annual PEO costs typically run $10,000 to $19,200.
What is the average PEO cost for a small business?
For a small business with 10-25 employees, the average PEO cost ranges from $12,000 to $48,000 per year. At the low end ($100 PEPM for 10 employees), the annual cost is $12,000. At the high end ($160 PEPM for 25 employees), the annual cost is $48,000. Percentage-of-payroll pricing varies more: a 10-person company with $500,000 total payroll at 6% pays $30,000 per year, while the same 10 people at 2% pay $10,000.
Is a PEO cheaper than hiring an HR manager?
It depends on company size. An HR manager costs $60,000-$90,000 per year in salary plus benefits (total cost $75,000-$120,000). A PEO for 25 employees at $100 PEPM costs $30,000 per year. At 25 employees, the PEO is significantly cheaper. At 50 employees ($60,000/year for the PEO), the math gets closer. At 75+ employees, hiring an HR manager plus using HR software ($2,400-$5,000/year) becomes cheaper than the PEO. The breakpoint is typically 40-60 employees.
What is the difference between PEPM and percentage-of-payroll PEO pricing?
PEPM (per employee per month) charges a flat dollar amount for each employee regardless of their salary. Percentage-of-payroll charges a percentage of your total gross payroll. PEPM is more predictable: $100 PEPM for 10 employees is always $1,000/month. Percentage pricing varies with pay: 6% of a $500,000 annual payroll is $30,000/year, but if you give raises that increase payroll to $600,000, the PEO cost rises to $36,000 without adding a single employee.
Do PEOs have hidden fees?
Yes. Common hidden fees include: setup fees ($500-$5,000), implementation fees ($1,000-$10,000 for larger companies), benefits markup (PEOs negotiate group rates but mark them up 5-20% before passing them to you), workers compensation audit adjustments (annual true-up based on actual vs estimated payroll), early termination fees (30-90 days notice or penalty), per-transaction fees for off-cycle payroll runs, and year-end reporting fees. Always request a complete fee schedule before signing.
Can HR software replace a PEO?
HR software can replace the HR administration portion of a PEO (onboarding, document management, employee records, compliance tracking, training) but not the co-employment, benefits pooling, payroll processing, or workers comp coverage. For small businesses that primarily need HR administration and already have separate payroll and benefits, HR software at $98-$198/month replaces the admin component of a PEO at a fraction of the cost. The total HR software stack (HR platform + payroll + benefits broker) typically costs 60-80% less than a PEO.
How much does it cost to leave a PEO?
Leaving a PEO typically costs $2,000-$10,000 in transition expenses: early termination fees (if within contract period), setup costs for replacement payroll and benefits, COBRA administration transfer, workers comp policy transition, and time spent re-enrolling employees in new systems. Most PEO contracts require 30-90 days written notice. Some PEOs charge a per-employee termination fee. Factor transition costs into your PEO vs alternatives analysis.
What does a PEO include for the price?
A typical PEO engagement includes: payroll processing and tax filing, benefits administration (health, dental, vision, 401k), workers compensation insurance and claims management, HR compliance guidance, employee handbook templates, unemployment claims management, and an HR support line. Some PEOs also include time tracking, performance management, and recruiting support. The breadth of services is the primary advantage over standalone HR software, which covers only the administration layer.
