PEO Cost for 15 Employees: What You’ll Actually Pay in 2026

You’ve asked three PEO providers for quotes. One came back at $2,100 per month. Another quoted $3,800. The third sent a vague proposal mentioning “customized pricing based on your needs.” Same headcount. Same industry. Wildly different numbers.

At 15 employees, you’re in a specific zone where PEO pricing gets interesting. You’re past the stage where most providers consider you too small to bother with. But you’re not big enough to command enterprise-level negotiating power. Every dollar matters because you’re likely still watching cash flow closely, but the HR complexity is real enough that ignoring it costs you time and sleep.

Here’s what you’ll actually pay, why the quotes vary so much, and how to figure out if the math works for your situation.

The 15-Employee Pricing Sweet Spot (and Why It Matters)

Fifteen employees sits at an inflection point in PEO pricing. Many providers won’t even quote below 10-15 employees—their operational model doesn’t work at smaller scales. Others will take smaller clients but charge premium rates that don’t make economic sense until you hit this threshold.

At this headcount, you’re typically looking at $150-$250 per employee per month for bundled services. That’s $2,250 to $3,750 monthly, or $27,000 to $45,000 annually just for administrative services. Some providers use a percentage-of-payroll model instead, usually landing between 2-4% of gross wages.

Why does this headcount change the math? You’ve crossed out of the “too small to matter” zone where PEOs either ignore you or charge inflated per-employee fees to offset their fixed costs. At 15 employees, most mid-tier providers see enough revenue potential to offer competitive pricing without treating you as a marginal account.

But you haven’t hit the 50+ employee threshold where enterprise pricing kicks in and you gain serious negotiating leverage. You’re in the middle—big enough to access reasonable rates, small enough that you’re still taking whatever pricing structure the PEO offers rather than negotiating custom terms.

This matters because the range of quotes you’ll receive is wider than at other headcounts. A 100-person company gets fairly consistent pricing across providers because the economics are predictable. A 5-person company gets consistently high per-employee rates because everyone knows the fixed costs don’t scale down. At 15 employees, you’re in the zone where one provider sees you as a great fit for their standard offering while another sees you as too small for their target market and prices accordingly.

The practical implication: you need to understand which providers are actually built for your size. A PEO that focuses on 100+ employee clients might quote you, but their pricing will reflect that you’re outside their sweet spot. A provider designed for 10-30 employee businesses will typically offer better rates because their entire operational model is built around your headcount.

Per-Employee vs. Percentage-of-Payroll: Which Model Hits Your Budget Harder

PEOs use two primary pricing models, and at 15 employees, the difference can be substantial.

Per-employee flat fee: You pay a set amount per employee per month regardless of their compensation. This creates predictable monthly costs, which helps with budgeting. If the rate is $175 per employee, you’re paying $2,625 monthly whether your team averages $40,000 or $100,000 in salary.

The catch? Watch for add-on fees that inflate the base rate. That $175 might not include workers’ comp administration, benefits enrollment support, or HR technology access. By the time you add the “required” modules, you’re at $220 per employee and wondering why the quote changed.

Percentage-of-payroll: You pay a percentage of gross wages, typically 2-4%. This scales with compensation, which means the same headcount can produce very different costs depending on your payroll mix.

Let’s run real numbers. Say you have 15 employees with an average salary of $60,000. Annual payroll: $900,000. At 3% of payroll, you’re paying $27,000 annually, or $2,250 per month.

Now assume the same 15 employees average $120,000 instead. Annual payroll: $1,800,000. At 3%, you’re paying $54,000 annually, or $4,500 per month. Same headcount. Same PEO services. Double the cost.

This is where compensation mix matters significantly. If you’re a tech startup with 15 developers averaging $110,000, percentage-of-payroll pricing hits harder than a per-employee model. If you’re a service business with 15 employees averaging $45,000, percentage-based pricing often works in your favor.

Here’s the comparison that matters. Take a 15-person team with mixed compensation—five employees at $45,000, seven at $65,000, and three at $95,000. Total annual payroll: $995,000.

Under a per-employee model at $175/month: $31,500 annually.

Under a percentage model at 3% of payroll: $29,850 annually.

Change the mix to ten employees at $50,000 and five at $130,000. Total payroll: $1,150,000.

Per-employee at $175/month: still $31,500 annually.

Percentage at 3%: now $34,500 annually.

The crossover point depends on your specific payroll structure. If your team skews higher in compensation, per-employee pricing usually wins. If compensation is lower or more evenly distributed, percentage-based pricing often costs less.

One more consideration: percentage-based pricing automatically adjusts when you give raises or hire higher-paid employees. Your PEO costs increase without any change in service level. Per-employee pricing stays flat unless headcount changes, but you lose the benefit of economies of scale if your payroll grows faster than headcount. Understanding how to compare PEO pricing models is essential before signing any agreement.

What’s Actually Included (and What Costs Extra)

The base PEO quote covers core administrative services. Typically, that includes payroll processing, tax filing and remittance, basic HR support (usually email or phone access to an HR generalist), and workers’ comp administration. You’re paying for the infrastructure to handle compliance filings, manage payroll taxes, and provide a basic level of HR guidance.

Benefits administration is usually included in the bundled fee, but here’s where it gets confusing. Administration means they handle enrollment, manage carrier relationships, and process changes. The actual insurance premiums are separate costs passed through from carriers.

For a 15-person group, monthly health insurance premiums typically run $8,000 to $15,000 depending on plan design, employee demographics, and how much the employer contributes. That’s $96,000 to $180,000 annually just for health coverage. Dental and vision add another $1,500 to $3,000 monthly.

These benefit costs are not part of the PEO administrative fee. They’re separate line items that flow through the PEO’s master policy but get billed to you based on actual enrollment and carrier rates. When a PEO quotes you $2,400 per month for 15 employees, that doesn’t include the $12,000 you’re also paying monthly for health insurance premiums.

Now the add-ons. A dedicated HR representative—someone assigned specifically to your account rather than general phone support—often costs an additional $200 to $500 monthly. Time tracking integrations with tools like QuickBooks or specialized scheduling software may carry setup fees ($500-$1,500) plus monthly platform fees ($50-$150).

Recruiting support, if you need help posting jobs, screening candidates, or managing onboarding workflows, typically runs $150 to $300 per hire or a monthly retainer of $300 to $600 for ongoing support. Compliance audits—where the PEO reviews your employee files, policies, and practices to identify risk—often cost $1,000 to $2,500 as a one-time service or $100 to $200 monthly if included as an ongoing benefit.

The bundled quote rarely includes everything you’ll actually need. Ask for an itemized breakdown showing base administrative fees, required add-ons, optional services, and estimated benefit premiums. Otherwise, you’ll sign at $2,400 monthly and realize six months later you’re actually paying $4,200 once all the extras are included. Many businesses discover hidden PEO fees only after they’ve already committed to a contract.

Factors That Push Your Quote Up or Down

Industry risk classification drives a significant portion of PEO pricing variation. Workers’ compensation rates vary dramatically based on what your employees actually do. A 15-person construction crew faces injury risk that translates to workers’ comp rates of 15-25% of payroll in many states. A 15-person accounting firm might see rates under 1% of payroll.

PEOs price this risk into their quotes. If you’re in a high-risk industry, expect the administrative fee to reflect that exposure even if workers’ comp is technically a separate line item. The PEO is taking on your risk profile under their master policy, and they’re not doing that without pricing it appropriately.

State complexity matters more than most business owners expect. Operating in California means navigating meal break requirements, complex overtime rules, and aggressive enforcement. New York adds its own layers of wage and hour complexity plus specific notice requirements. Multi-state operations multiply the compliance burden.

A 15-person company operating in a single business-friendly state will get better pricing than the same headcount spread across California, New York, and Illinois. The PEO’s compliance overhead increases with every additional state, and that shows up in your quote.

Claims history and turnover rate signal risk to PEOs. If you’ve had multiple workers’ comp claims in the past three years, expect higher pricing. Companies with a high experience modification rate often face premium surcharges that significantly impact their total costs.

A clean track record earns better rates. No significant workers’ comp claims in three years, turnover under 20%, no wage and hour disputes—that profile gets quoted at the lower end of the pricing range. A messy history with multiple claims, high churn, and past compliance issues pushes you toward the higher end or disqualifies you entirely with some providers.

When 15 Employees Makes a PEO Worth It (and When It Doesn’t)

The math works when you’re spending significant time on HR tasks that don’t generate revenue. If you’re putting in 10+ hours weekly handling payroll issues, fielding benefits questions, updating employee handbooks, or worrying about compliance deadlines, that’s time with a real cost.

Say you value your time at $100 per hour (conservative for most business owners). Ten hours weekly is $1,000 in opportunity cost. That’s $4,000 to $4,300 monthly—more than most PEO fees at 15 employees. If the PEO genuinely takes that workload off your plate, the economics make sense even before considering the benefits access and compliance protection.

The bundled approach also works when you’re struggling to offer competitive benefits. At 15 employees, you don’t have the buying power to negotiate good health insurance rates on your own. Joining a PEO’s master policy can cut benefit costs by 15-25% compared to small group rates, which often offsets a significant portion of the administrative fee.

Reconsider if your workforce is stable, benefits aren’t a competitive priority, and you have a reliable payroll provider handling the basics. A 15-person team with low turnover, minimal benefits needs, and straightforward payroll doesn’t generate the complexity that justifies PEO pricing.

In that scenario, you might be paying $35,000 annually for services you could handle with a $200/month payroll platform plus occasional HR consulting at $150/hour. Run the math on your actual usage. If you’re calling the PEO’s HR hotline twice a year and everything else is automated, you’re overpaying for access you don’t use. A thorough PEO cost benefit analysis can help clarify whether the investment makes sense for your specific situation.

Break-even thinking helps clarify the decision. Compare total PEO cost against hiring a part-time HR coordinator at 20 hours weekly ($25-$35/hour in most markets) plus a standalone benefits broker (usually no direct cost—they’re compensated by carriers). That combination might run $30,000 to $40,000 annually and give you more personalized support than a PEO’s shared service model.

The PEO wins when you need the full bundle: payroll, benefits, compliance support, workers’ comp management, and risk mitigation. It loses when you’re paying for comprehensive services but only using basic payroll and benefits administration.

What Your Quote Should Actually Look Like

PEO pricing at 15 employees is highly variable. Quotes for the same headcount, same industry, and same state can range from $30,000 to $60,000 annually. That’s not a small variance—it’s double.

The difference comes down to pricing model, service inclusions, risk assessment, and how well your profile fits the provider’s target market. A PEO built for 10-30 employee businesses will quote you better rates than one focused on 100+ employee clients. A provider with strong presence in your industry will price more competitively than one taking on unfamiliar risk.

Get multiple quotes. Three minimum. Ask for itemized breakdowns showing base administrative fees, required add-ons, optional services, and estimated benefit premiums separately. A single all-in number hides too much.

Question what’s actually included. Is the dedicated HR rep part of the base fee or an add-on? Does workers’ comp administration include claims management or just policy placement? Are compliance audits included or extra?

Consider whether the bundled model fits your actual needs. If you’re paying for comprehensive HR support but only need payroll and benefits, you’re subsidizing services you don’t use. If you’re drowning in compliance complexity and the PEO genuinely solves that, the premium over standalone solutions makes sense.

Before you renew your PEO agreement, compare your options. Most businesses overpay due to bundled fees and unclear administrative markups. We break down pricing, services, and contract structures so you can make a smarter decision.

The right PEO at 15 employees should feel like a strategic partner that’s genuinely reducing your workload and risk exposure. If it feels like an expensive payroll provider with extra features you don’t use, you’re probably in the wrong arrangement.
