Am I Paying Too Much for My PEO? Benchmarks by Company Size

How to Know If Your PEO Fees Are Out of Line

Most business owners sign their first PEO contract without a solid reference point for what a fair price looks like. A few years later, they are still paying the same rate, assuming it is competitive, while the PEO quietly collects a margin that has grown alongside their headcount. If you have never benchmarked your PEO admin fee against the market, there is a reasonable chance you are overpaying.

This article gives you the benchmarks you need, broken down by company size, so you can make an informed judgment about where your current deal stands.

Understanding How PEO Fees Are Structured

Before you can benchmark anything, you need to know what you are actually paying. PEOs charge in two primary ways:

• Percentage of gross payroll: The admin fee is calculated as a percentage of your total payroll each pay period. This model is common and easy to audit.
• Per-employee per-month (PEPM): A flat dollar amount charged for each active employee each month, regardless of their salary.

Some PEOs blend both models or embed costs inside your workers compensation and benefits invoices to make the true admin fee harder to identify. Your first job is to isolate the pure administrative markup from everything else. Look for a line item labeled admin fee, service fee, or management fee on your invoice. If you cannot find one clearly, that is a warning sign worth investigating.

PEO Admin Fee Benchmarks by Company Size

Small Companies: 5 to 24 Employees

Small employers are the most likely to overpay because they have less negotiating leverage and often rely on a single vendor quote. The market range for companies in this band is roughly 4 to 8 percent of gross payroll, or $120 to $200 PEPM depending on the services included.

If you are paying above 7 percent of payroll or above $180 PEPM with a standard service package, that is worth questioning. Some PEOs justify higher rates for very small groups due to the fixed costs involved, but others use small-employer pricing as a margin opportunity. Knowing the difference requires comparison shopping.

Mid-Size Companies: 25 to 99 Employees

This is the range where pricing becomes more competitive and where you should expect meaningful rate reductions compared to small-employer pricing. A reasonable benchmark here is 2 to 6 percent of gross payroll, or $90 to $160 PEPM.

Companies at 50 or more employees often qualify for better benefits pricing from carriers, which can shift the overall value calculation in their favor even at similar admin fee levels. The key is not just looking at the admin fee in isolation but at the total cost of the PEO relationship, including what you would pay for equivalent benefits and HR infrastructure on your own.

Larger Companies: 100 to 250 Employees

At this size, you have real leverage. PEOs want your business, and the economics of serving a 150-person company are favorable enough that they can compete aggressively. Market rates drop to roughly 1.5 to 4 percent of gross payroll, or $70 to $130 PEPM for a full-service arrangement.

If you started with a PEO as a 20-person company and never renegotiated as you grew, you may still be on early-stage pricing. That is one of the most common and costly mistakes we see. A company that grew from 30 to 120 employees without ever revisiting their contract could easily be paying 2 to 3 percentage points above what the market would offer them today.

Red Flags That Suggest You Are Overpaying

Beyond the raw numbers, certain contract and billing patterns suggest your PEO relationship has drifted out of alignment with the market.

• No rate review in three or more years: PEO pricing has become more competitive. If your rate has not been revisited since you signed, you are likely behind the current market.
• Your headcount has grown significantly: Admin fee percentages should decrease as your employee count increases. If yours has stayed flat, you have not captured the volume discount you have earned.
• Bundled invoicing: If your PEO combines workers compensation, benefits, taxes, and admin into a single figure without itemizing, you cannot verify what you are actually paying for administration. That opacity typically benefits the PEO.
• Auto-renewing contracts with no market check: Many PEO agreements renew automatically with modest CPI adjustments. Without an outside comparison, you have no way to know if those adjustments are keeping you at market or drifting above it.
• High PEPM for low-wage workforces: A PEPM model charges the same amount per head regardless of salary. If your workforce is largely hourly or lower-wage, a PEPM structure can represent a disproportionately high percentage of payroll compared to what a percentage-based model would cost.

What You Should Actually Do With These Benchmarks

Pull your most recent PEO invoice and locate the admin fee line. Calculate it as a percentage of your gross payroll for that period. Then compare it to the range for your company size above.

If you are within range, that does not necessarily mean you have the best deal available. Pricing varies by PEO, by the services bundled, and by the carrier relationships each PEO maintains. Being at the midpoint of the range for your size still means there may be a better-fit PEO at the lower end of that range with equivalent or better service.

If you are above the benchmark range, you have a clear case for renegotiation or a competitive review. Most business owners do not realize that switching PEOs is far more straightforward than it was even five years ago. The transition process is manageable, and the savings over a two to three year period often justify the effort significantly.

Why an Independent Broker Gives You Better Benchmarks Than the PEO Itself

Asking your current PEO if you are getting a fair rate is like asking a vendor if their price is reasonable. You may get a reassuring answer, but you are not getting an objective one.

PEO Consulting Partners is an independent broker. We do not represent any single PEO, and our fee is paid by whichever PEO you choose, not by you. That structure means our incentive is to find you the best match at the best price, because that is the only way we earn a long-term referral relationship. We compare 36 PEOs and serve clients across 46 states, with same-day follow-up so you are not waiting a week to get answers.

The benchmark ranges in this article are a starting point. A real comparison gives you actual quotes from competing vendors against your specific payroll, workforce profile, and service needs. That is where the real number comes from.
