How Much Does HR Outsourcing Cost?

If you are researching HR outsourcing, the first question is almost always the same: what does it actually cost? The honest answer is that it depends on your company size and how much you need done — but the ranges are more predictable than most people expect. This guide breaks down real pricing for small and mid-size businesses, the three pricing models providers use, what a company your size should expect to pay, and how to budget for it.

HR outsourcing cost at a glance

For most small and mid-size businesses, HR outsourcing costs between $1,500 and $6,500 per month. Here is how that breaks down by company size:

Notice that the per-employee cost drops as you grow. That is normal — there is a baseline amount of HR work that exists regardless of headcount, so smaller companies pay more per person. As you add employees, the fixed portion spreads across more people.

How much does HR outsourcing cost for a 30-employee company?

A company with 30 employees typically pays $3,000 to $4,000 per month for comprehensive HR outsourcing. On a per-employee basis, that is roughly $100 to $130 per employee per month. That price generally covers compliance monitoring, employee onboarding and offboarding, employee relations and questions, performance management support, payroll coordination, and ongoing HR advice.

For comparison, a full-time HR manager for that same 30-person company costs $70,000 to $90,000 per year fully loaded — roughly $6,000 to $7,500 per month once you include salary, payroll taxes, benefits, software, and the cost of hiring them. Outsourcing delivers senior-level expertise at 40–60% of that cost.

The three HR outsourcing pricing models

Providers price HR outsourcing in three main ways. Understanding which model you are being quoted helps you compare offers accurately.

1. Flat monthly retainer

The most common model for small businesses. You pay a fixed monthly price for a defined scope of work — for example, $3,500/month for ongoing HR support up to a certain number of hours. The advantage is predictability: you know exactly what you are paying every month regardless of how many questions come up. This is the model Bevel HR uses because it is the easiest to budget and there are no surprise charges.

2. Per-employee-per-month (PEPM)

You pay a set rate multiplied by your headcount — typically $80 to $200 per employee per month. A 40-person company at $100 PEPM would pay $4,000/month. This model scales automatically with your team, but it can get expensive as you grow and it sometimes bundles in software costs that inflate the per-head rate. Ask what is actually included at the quoted PEPM rate.

3. Project-based pricing

For one-time work rather than ongoing support, providers charge a flat project fee. Common examples:

What about setup fees?

Many HR outsourcing providers charge a one-time setup or onboarding fee, typically $500 to $2,500. This covers the initial HR audit, reviewing your existing documentation, and getting systems in place. Some providers — including Bevel HR — roll the initial audit into the first month rather than charging a separate setup fee. When comparing providers, always ask whether there is a setup fee on top of the monthly rate, because it affects your true first-year cost.

How do companies budget for HR outsourcing?

The most common approach is to treat HR outsourcing as a fixed monthly operating expense, usually landing somewhere between 1% and 3% of total payroll. A company with $2 million in annual payroll might budget $2,000 to $5,000 per month for outsourced HR.

The reason outsourcing is easier to budget than a full-time hire is predictability. A full-time HR employee comes with variable costs — benefits, payroll taxes, bonuses, raises, PTO, software, and the significant cost of turnover if they leave. A fractional HR retainer is one predictable number every month with none of those surprises. For a growing company trying to forecast cash flow, that predictability is often worth as much as the cost savings.

What drives the price up or down?

Three factors move your quote within the ranges above. First, scope — basic compliance support costs less than full-service HR that includes recruiting coordination and performance management. Second, complexity — companies with employees across multiple states, hourly and field labor, or industry-specific compliance like prevailing wage will pay more because the work is harder. Third, seniority — some providers staff your account with junior coordinators while others give you a senior HR professional directly. You generally get what you pay for on that last one.

How to compare HR outsourcing providers on price

When you get quotes, compare them on the same basis. Ask each provider: Is this a flat retainer or per-employee pricing? Is there a separate setup fee? What is included in the monthly rate, and what costs extra? Who actually does the work — a senior person or a junior coordinator? Is there a minimum contract length? Two quotes that look similar on the monthly number can be very different once you account for setup fees, scope, and who is handling your account.
