Named PEO · TriNet
What TriNet costs — flat per-employee pricing, explained
TriNet is unusually clear about one thing: its PEO fee is flat per employee per month, never a percentage of payroll. It is less clear about the number itself. Here is what the pricing page actually says and what to ask.
Short version: a flat PEPM administrative fee, custom-quoted by size, industry, geography, and services; TriNet’s own FAQ uses $150 PEPM as an illustration, and third-party guides estimate $100–$140. See how it compares →

How TriNet prices
TriNet’s pricing page says it “does not publish standard list pricing” and that pricing is customized by company size, industry, geographic footprint, and services. The one number on the page is an example: 20 employees at $150 PEPM equals a $3,000 monthly administrative fee. Software Finder’s benchmark puts the typical range at $100–$140 PEPM. TriNet requires a minimum worksite employee count but does not state it. Most contracts, per TriNet, offer flexible terms without a long-term commitment.
Separate from the fee
Benefit premiums (medical, dental, vision — by plan, carrier, and enrollment), the payroll taxes themselves (FICA, FUTA, SUTA), and add-ons: background checks, drug screening, premium training, certain risk-mitigation services.
Why flat PEPM matters
Your fee doesn’t rise with raises, bonuses, or overtime. For companies with high average wages or seasonal overtime, this alone can make TriNet cheaper than a percentage-of-payroll PEO with a lower headline rate.
Industry focus
TriNet markets vertical expertise (technology, life sciences, financial services, nonprofits, professional services). Ask what that means in practice for your industry.
Who TriNet tends to fit
- Professional-services, technology, and higher-wage employers where flat PEPM beats a percentage
- Companies that want a mature platform and industry-specific benefits packages
- Employers who value no long-term contract
- Less likely to fit: high-risk field workforces where workers’ comp pricing, not the admin fee, decides the deal
Fit is our read from pricing structure and public positioning, not a review of TriNet’s service.
Ask these before you sign with TriNet — or anyone
- Is the fee flat per employee or a percentage of payroll — and what happens to it when you give raises or add overtime?
- What is the fee on employees 1–10 versus 50+? Most PEOs step the rate down with headcount; ask for the schedule.
- What is the renewal cap? If the contract doesn’t limit year-two increases, assume there isn’t one.
- Is workers’ comp on a master policy, and what class codes did they assume for your crews?
- What are the exit terms — notice period, who owns the benefits plan year, and what it costs to leave mid-year?
- What is billed outside the fee: implementation, state registrations, background checks, 401(k) administration?
How we price TriNet against the market
Same census, same comp assumptions, same benefits contribution, two to four PEOs side by side. With TriNet, the admin fee is usually easy to compare; the benefits premiums and comp are where the comparison is won or lost. What a PEO costs, in general →
TriNet is a trademark of its owner. My PEO Pros is an independent broker and is not affiliated with, sponsored by, or endorsed by TriNet. Pricing facts are from TriNet’s public website or clearly labeled third-party estimates as of November 2026; your quote is the only number that counts.
TriNet tells you the fee is flat and won’t tell you what it is. That is fine — that is what a quote is for. Just make sure you see it next to two others on the same assumptions.Jeff Gibson, SHRM-CP · Founder & PEO Advisor
Common questions
Frequently asked questions
Does TriNet publish its PEO pricing?
No. TriNet states it does not publish standard list pricing. Its FAQ uses $150 per employee per month as an example only.
Is TriNet a percentage of payroll?
No. TriNet charges a flat per-employee-per-month fee and says so explicitly. Benefit premiums and payroll taxes are separate.
Does using a broker make TriNet cost more?
No. The PEO pays the broker fee out of a budget it already carries, and the fee is the same whichever PEO you choose. You get the same TriNet quote — plus alternatives on identical assumptions.
Can you get me a TriNet quote?
Yes, and we run it next to the alternatives so you can see where it wins and where it doesn’t. Bring your census and current invoices; the comparison is free.
