How PEO Pricing Works: Fees, Models, and What to Watch For

PEOs price one of two ways: a flat fee per employee per month, or a percentage of your gross payroll. The administrative fee is only part of what you pay. Health insurance, workers’ comp, and state unemployment are separate lines, and the way a PEO bundles or breaks them out is where quotes get hard to compare. Here is how to read one, from someone who reads them for a living.

The two pricing models

Per employee per month. Often written as PEPM. You pay a fixed dollar amount for each employee on the payroll each month. Your cost does not change when you give raises or pay bonuses. It goes up only when headcount goes up. This model is easy to budget and easy to compare across PEOs.

Percentage of gross payroll. You pay a percentage of every dollar of wages. Your fee rises with raises, overtime, and bonuses, not just headcount. This model can work in your favor if you have mostly part time or lower wage employees, since the fee scales with actual payroll dollars rather than seats.

Neither model is better in the abstract. A PEPM quote looks attractive to a company with well paid staff. A percentage quote looks attractive to a company with lots of part timers. Ask for both if the PEO offers both, and run the numbers on your own payroll.

What is inside the admin fee

The admin fee is supposed to cover payroll processing and tax filing, the technology platform, HR support, compliance guidance, benefits administration, and the PEO’s overhead. Some PEOs fold part of the workers’ comp cost into it, and that is the first thing to watch for.

The lines that are not the admin fee

Health insurance. Priced per employee per month based on the plan tier each employee chooses. The PEO’s master plan is usually cheaper than what a small group can buy alone, but you need the actual rates by plan to know.

Workers’ compensation. Priced as a rate per one hundred dollars of payroll, by class code. This is the line I push hardest on. Ask for workers’ comp quoted separately, by class code, not blended into the admin fee. If it is blended, you cannot tell whether you are getting a good rate on comp or overpaying on admin.

State unemployment insurance. In some states the PEO files SUI under its own account, which means you inherit the PEO’s rate. Compare it to your current rate. If the PEO’s rate is higher, that is a hidden cost. If it is lower, that is a hidden saving.

Employer payroll taxes. FICA and FUTA are the same either way. Watch for whether the quote presents them as part of the PEO’s cost or separately. They are your cost regardless.

How to compare two PEO quotes

Ask every PEO for the same four numbers on the same headcount and payroll: admin fee (in whichever model they use, converted to a monthly dollar figure), health insurance rates by plan tier, workers’ comp rate by class code, and the SUI rate they will file under. Put them in one spreadsheet. Add your current costs for benefits, comp, and any HR spend in a fifth column. Now you are comparing total cost of employment, which is the only comparison that matters.

A quote that will not break out these lines is a quote you cannot evaluate. Politely insist.

Questions that reveal the real price

Is the admin fee locked for the contract term, or can it change at renewal? What happened to renewals for clients who joined two years ago? Are there setup or implementation fees? What does it cost to add a state? Are there fees for off cycle payrolls, corrections, or year end? What is the termination notice and is there an exit fee? Are health rates locked for twelve months after the health questionnaires, or can they be adjusted?

That last one matters more than people expect. Completing personal health questionnaires feels intrusive, but it is how your rates get locked. Skip them and the PEO can reprice you after the first renewal.

When a PEO saves money and when it does not

A PEO typically comes out ahead when the group is 10 employees or more, when health insurance is a significant cost today, when workers’ comp rates are elevated, or when the alternative is hiring HR staff. It typically does not come out ahead for very small groups with no benefits, for companies with an unusually low workers’ comp exposure, or for companies that already have excellent benefits through a large parent.

The honest answer is that it depends on your numbers, and that is why the four line comparison above exists.

Where a broker fits

PayThrive gets the quotes in a comparable format, flags the blended lines, and negotiates when there is room to. The providers pay us, so there is no cost to you for the comparison. If you are wondering whether a PEO is even the right category, start with who benefits most from a PEO. If you are already in one, read the PEO red flags before renewal.

Frequently asked questions

What is a typical PEO admin fee?
It varies widely by PEO, headcount, and services. Get quotes for your actual group rather than relying on a published average, and compare the total cost including benefits and comp.

Do PEO fees go up every year?
Admin fees may be fixed for the term. Health insurance renews annually and can move. Ask how each line renews before you sign.

Can I negotiate PEO pricing?
Often, especially on the admin fee and on setup costs. A broker who brings the PEO multiple clients has more room to negotiate than a single company does.

Is a percentage of payroll model ever the right choice?
Yes, for groups with mostly part time or seasonal staff, where a flat per employee fee would charge you full price for people working a few hours a week.
