How Much Does A PEO Cost?
Quick Answer
PEOs charge either a percentage of total payroll or a flat per-employee-per-month fee, running meaningfully higher than a standalone payroll service. The comparison only makes sense against everything bundled: payroll, HR, compliance, workers' comp, and benefits access.
PEO pricing confuses owners because the invoice is bigger than a payroll service’s — and the comparison is wrong from the start. Different products, different math.
How do PEOs structure pricing?
Two models dominate:
| Model | How it works | Watch for |
|---|---|---|
| Percentage of payroll | Fee scales with total wages | Every raise raises the fee |
| Per-employee-per-month | Flat administrative fee per head | Cleaner to compare; check what’s excluded |
Either way, the total runs meaningfully above a standalone payroll service — that much is by design, because the product is bigger.
What does the fee actually buy?
The bundle: payroll and tax filings, HR support, compliance help, workers’ compensation, benefits administration, and — the headline — access to benefits pricing pooled across the PEO’s tens of thousands of worksite employees. The mechanism behind the pooling is co-employment, which lets a nine-person company buy benefits like a large one. A business already paying for a payroll service, an HR consultant, workers’ comp, and a benefits program is often paying PEO-like money in pieces without noticing.
How should a business compare the cost?
Against the full stack, not the payroll line: current vendor invoices, plus owner hours at their real value, plus the recruiting weight of better benefits, minus the PEO fee. Where the math lands depends heavily on headcount and whether benefits matter to the next hire — the complete comparison across DIY, payroll service, and PEO is worked through in the total cost breakdown. Worth pricing at the same time: what leaving later involves, because exit terms belong in the entry decision.
Frequently Asked Questions
Which is better: percentage-of-payroll or per-employee pricing?
Flat per-employee-per-month pricing is more transparent and does not inflate with raises or bonuses. Percentage pricing can start lower but grows with every payroll increase — worth modeling before signing.
Why do PEOs cost more than payroll services?
The fee covers co-employment: HR support, compliance work, workers' comp, and benefits administration on top of payroll. A payroll service processes pay; a PEO takes on a slice of being the employer.
What hidden costs should businesses watch for in PEO contracts?
Setup fees, per-transaction charges, benefits administration markups, and the pricing behavior at renewal. A fee schedule in writing, itemized, is the baseline ask.
When does a PEO's cost pencil out?
When the bundled benefits access, offloaded compliance, and recovered owner hours exceed the premium over separate vendors — typically for businesses around ten or more employees that want to compete on benefits.
