A Professional Employer Organization (PEO) bundles payroll, benefits, workers' comp, and HR compliance under a co-employment arrangement, and it prices that bundle in one of two ways. Understanding which model a PEO uses - and what's actually inside the fee - is the key to comparing quotes honestly, because the headline number rarely tells the whole story.

The two PEO pricing models

Per-employee-per-month (PEPM): a flat dollar amount per employee each month. Predictable, easy to budget, and it doesn't balloon when you give raises. This is the more transparent model.
Percentage of payroll: a percent of your total gross payroll, typically in the low-to-mid single digits. It scales with wages, so it can get expensive as salaries rise, and it's harder to forecast.

All else equal, a flat per-employee fee is easier to budget than a percentage of payroll - because your PEO bill shouldn't jump every time you give someone a raise.

What's usually included in the fee

Payroll processing and payroll tax filing under the PEO's arrangement
Access to large-group health, dental, and vision plans
Workers' compensation coverage and claims handling
HR support, handbooks, and compliance guidance
Onboarding, PTO tracking, and basic HR administration

Critically, the administrative fee is only part of your total cost. The bigger line item is usually the benefits themselves - the health insurance premiums you and your employees pay through the PEO's plans. When you compare PEOs, compare the all-in cost (admin fee plus the actual benefit premiums you'd pay in your state), not just the per-employee admin number.

Watch for these extra costs

Setup or implementation fees to get started
Minimums or surcharges for very small teams
Add-on modules (advanced HR, time tracking, recruiting) billed separately
What happens to your benefits and rates if you leave the PEO later

Justworks

If predictable pricing is a priority, Justworks is our top pick. It uses a straightforward flat per-employee-per-month model with published tiers, so you can estimate your admin cost before a sales call - unusual in a category where most quotes are opaque. You still need to price the benefit plans themselves for your state, but the admin side is refreshingly clear, and you get access to strong large-group health plans, payroll, compliance, and HR support in one simple platform.

Pros

✓ Flat per-employee pricing you can estimate up front
✓ Access to strong large-group benefits
✓ Payroll, compliance, and HR support included
✓ Clean, easy-to-use platform

Cons

✕ Benefit premiums are separate and vary by state
✕ Per-employee cost is still higher than DIY payroll

How to estimate your PEO cost

Decide which model you're being quoted - flat PEPM or a percentage of payroll - and convert both to an annual dollar figure so you can compare.
Add the actual benefit premiums you'd pay in your state; this is usually the largest piece.
Factor in any setup fees and add-on modules you'll turn on.
Compare that all-in total to what you spend today on payroll, benefits brokering, and HR time.
For most small US teams, start by pricing Justworks, then compare Rippling and Paychex.

A PEO is rarely the cheapest way to run payroll on a line-item basis. The question is whether big-group benefits, offloaded compliance, and reclaimed time are worth the premium - and for a growing small business competing for talent, they often are.
