How much does a PEO cost? The admin fee alone runs about $75 to $300 per employee per month, or $900 to $3,600 a year. PEOs also earn margin on state unemployment tax, workers' comp and sometimes health premiums, and many bill a la carte fees on top, so the real cost is usually higher.
Most PEO quotes lead with one number: the admin fee. After more than ten years inside three PEOs, I can tell you that number is where the conversation starts, not where your cost ends. This guide breaks down every layer of what a PEO costs, with the math, so you can compare quotes on what you will actually pay. For how pricing models work across the industry, see our PEO pricing guide.
How much does a PEO cost? The short version
A PEO's total cost has five layers. The admin fee is the one you see. The other four are often built into lines that look like taxes or insurance.
| Cost layer | How it is charged | Typical range |
|---|---|---|
| Admin fee | Per employee per month, or a percent of payroll | $75 to $300 per employee per month (in my experience) |
| State unemployment (SUI) margin | A rate above what the PEO pays the state | $0 to a few hundred dollars per employee per year |
| Workers' comp margin | A load on the rate per $100 of payroll | Small for office teams, thousands for field crews |
| Health insurance load | An amount above the carrier's cost, or risk-based pricing | $0 at some PEOs, a few percent at others |
| A la carte fees | Per event, per form or per year | A few hundred to a few thousand dollars a year |
How much does a PEO cost per employee?
In my experience, the PEO admin fee runs from about $75 to $300 per employee per month. Most small business quotes I see land between $80 and $200, and our guide to average PEO fees for small businesses breaks that down by service level.
The low end is a self-service platform with standard benefits. Justworks, for example, lists $79 and $124 per employee per month for its two PEO plans (October 2026). The high end is a small group with a dedicated HR team, several states, a high-risk industry or extra modules like HR consulting and time tracking.
Published industry ranges run lower than what many small companies get quoted. ADP's own guide puts typical fees at $40 to $160 per employee per month, or 2% to 12% of payroll. In my experience, companies under 20 employees rarely see the bottom of that range, because fixed service costs are spread across fewer people.
Percent-of-payroll pricing deserves a warning. At 3% of a $75,000 salary, the fee is about $188 a month, and it rises with every raise, bonus and commission even though the PEO does no extra work.
What goes into the total cost of a PEO?
The total cost of a PEO is the admin fee plus whatever margin sits inside the taxes, insurance and extras you pay through it. The taxes and premiums themselves are costs you would pay anyway. The question is how much the PEO adds on top.
That margin is a normal part of the business model. Our guide to how a PEO makes money covers each revenue line in depth. Here is what each one tends to cost you.
How much do PEOs make on state unemployment tax?
In PEO-reporting states, the PEO pays state unemployment tax at its own pooled rate, then bills you at a rate set by your contract. The gap is margin, and it is printed as a tax, so most clients never question it.
Here is the math in New York. The state's 2026 taxable wage base is $17,600 per employee, and the new employer rate is 4.1%, with rates ranging from 1.7% to 9.5%. A new employer pays about $722 per employee a year. If a PEO bills you 1 to 2 points above the rate it actually pays, that is $176 to $352 per employee a year, or $15 to $29 a month, on top of the admin fee. These markups are illustrative; ask each PEO for the rate it pays the state.
It can cut the other way. If your own rate is high because of past layoffs, a PEO's pooled rate can save you money.
How much do PEOs make on workers' comp?
Workers' comp is priced per $100 of payroll for each job class code, and through a PEO that rate is set by the PEO, not quoted to you by a carrier. Any load on top of the carrier's cost is margin, and many large PEOs also keep part of the claims risk.
How much it matters depends on your work. Take an illustrative office rate of $0.20 per $100 of payroll: a $75,000 employee costs $150 a year to cover, so even a 20% load is only $30. Take an illustrative construction rate of $8 per $100: a $60,000 worker costs $4,800 a year, and the same 20% load is $960. For field crews, workers' comp margin can be bigger than the admin fee. Our guide to PEO workers' comp shows how to benchmark your rates.
What about health insurance?
Health premiums are the biggest line on most PEO invoices, so even a small load adds up. KFF's 2026 survey puts the average employer premium at $9,804 for single coverage and $28,303 for family coverage. An illustrative 2% load on single coverage is about $196 per employee a year.
Not every PEO adds one. ADP reports its benefits pass-throughs as zero-margin, while TriNet and Insperity run risk-based plans where they earn more when claims come in low. Ask each PEO whether its rates include any administrative load, and get a side-by-side quote for the same plans outside the PEO.
What a la carte fees do PEOs charge?
On top of the admin fee, many PEOs bill a la carte fees for specific tasks or events. Each one is small. Together they can add hundreds or thousands of dollars a year, and they are the easiest costs to miss in a proposal.
The ones I see most often: setup or implementation fees, off-cycle payrolls for bonuses and corrections, new hire reporting, ACA reporting on Forms 1094-C and 1095-C, W-2 corrections and year-end forms, COBRA and 401(k) administration, multi-state fees, monthly minimums, and early termination fees.
For a sense of how these are priced, look at a published payroll fee schedule. Paycor, a payroll provider, lists $3 per printed 1095-C, $105 per W-2 correction and $250 per amended tax return, plus $100 per pay run adjustment. In my experience, PEOs that charge a la carte price in a similar range. Some, like Justworks, say they charge no implementation fee.
What a PEO really costs a 20-person company
Here is how the layers stack for an illustrative 20-person New York office team with an average salary of $75,000, single coverage for everyone and a $125 admin fee. The SUI, workers' comp and health figures use the illustrative markups above.
| Cost layer | Per employee per year | 20 employees per year |
|---|---|---|
| Admin fee ($125 a month) | $1,500 | $30,000 |
| SUI markup (1 point on $17,600) | $176 | $3,520 |
| Workers' comp load (20% on $150) | $30 | $600 |
| Health load (2% on $9,804) | $196 | $3,920 |
| A la carte fees (setup, off-cycle runs, forms) | $75 | $1,500 |
| Total cost above taxes and premiums | $1,977 | $39,540 |
That is about $165 per employee per month against a $125 sticker price, or roughly 32% more than the admin fee. Your numbers will differ, but the pattern holds: the fee is the floor, not the total.
How to lower what you pay
You lower what a PEO costs by making every layer visible, then negotiating each one. Ask for an unbundled invoice showing the admin fee, the SUI rate and wage base for each state, workers' comp rates per $100 by class code, and health premiums by plan and tier. Then get a written fee schedule and make it part of the contract.
Push for a per-employee fee if you pay bonuses or commissions, ask for a cap on your first renewal, and compare at least three quotes built on the same census. Our guide to PEO discounts covers every lever, and PEO renewal explains why your year-two price matters more than your first quote.
As a licensed health insurance and PEO broker, I can also quote group health plans outside a PEO, which is the cleanest way to see whether a PEO's health rates are fair. Book a 20-minute call with me. Bring your current PEO invoice or proposal and a rough employee list, and I'll show you what you are really paying per employee.
Frequently asked questions about PEO cost
How much does a PEO cost per employee per month?
In my experience, the admin fee alone runs from about $75 to $300 per employee per month, with most small business quotes landing between $80 and $200. Add state unemployment and workers' comp margins, health loads and a la carte fees, and the real cost is higher. In our 20-person example, it came to about 32% above the admin fee.
How much does a PEO cost per year?
For the admin fee alone, about $900 to $3,600 per employee per year. A 20-person company paying $125 per employee per month spends $30,000 a year on the fee before any margins or extra charges.
Is a PEO cheaper than doing HR yourself?
Sometimes. NAPEO reports a 27% average return from cost savings for PEO clients, but that is an industry average. Whether you save depends on your health plan pricing, workers' comp rates and the fee you negotiate, so compare real quotes.
Do PEOs charge a percentage of payroll?
Some do. ADP puts the industry range at 2% to 12% of payroll. Percent-of-payroll pricing rises with every raise and bonus even though the PEO does no extra work, so most companies with variable pay are better off with a flat per-employee fee.
What hidden fees do PEOs charge?
The most common are setup fees, off-cycle payroll charges, new hire reporting, ACA reporting, W-2 corrections, multi-state fees, monthly minimums and early termination fees. Ask for a full fee schedule and make it part of the contract.
