The 2026 cost of outsourced HR is typically $500 to $7,000 per month for consulting and HR support, or about $40 to $160 per employee per month for a PEO's administrative fee. A full-service PEO may cost roughly $100 to $200 per employee per month, with benefits and other employment costs added or billed separately. Payroll-only services usually cost less.
Your price depends on the services you need. Payroll administration, compliance support, employee relations, benefits, workers' compensation and fractional HR leadership each affect the total.
Outsourced HR Costs at a Glance
| Outsourcing option | Typical cost | What it usually covers |
|---|---|---|
| Payroll software or payroll administration | From about $8 per employee monthly, plus possible base fees | Payroll processing, tax filings and employee records |
| Administrative HR support | $500 to $1,500 monthly | Payroll coordination, HR administration and compliance calendars |
| HR advisory services | $1,000 to $6,000 monthly | Policies, employee relations guidance and compliance advice |
| Fractional HR leadership | $4,000 to $7,000 monthly | Ongoing HR management, strategy and execution |
| PEO administrative fee | $40 to $160 per employee monthly, or 2% to 12% of payroll | Payroll, HR administration, compliance, benefits administration and risk support |
| Full-service PEO budget | About $100 to $200 per employee monthly in some small-business estimates | Payroll, benefits and wider HR administration |
| Employer of Record service | Example: $599 per employee monthly | Hiring and employing workers in another country |
These ranges are for budgeting, not fixed prices. Providers may bill benefits, workers' compensation, payroll taxes, implementation and optional services separately.
What Does a PEO Cost?
A PEO usually charges either a percentage of payroll or a fixed fee per employee. ADP reports administrative fees of about 2% to 12% of total payroll, which is equivalent to roughly $40 to $160 per employee per month, depending on the workforce and services included.
For a business whose employees earn an average of $60,000 per year, monthly payroll is about $5,000 per employee:
- At 2% of payroll, the administrative fee is about $100 per employee per month.
- At 8%, it is about $400 per employee per month.
- At 12%, it is about $600 per employee per month.
PEO pricing can also depend on:
- Number of employees
- Employee locations and number of states
- Industry and job-related risk
- Workers' compensation claims history
- Benefits plan design
- Payroll frequency and complexity
- Services included in the agreement
The administrative fee may not represent the full PEO cost. Benefits, workers' compensation and other HR services may appear as separate charges.
What Do PEO Providers Charge in Practice?
Published Justworks rates provide one example of what full-service HR outsourcing can cost before benefits and other employment expenses:
- PEO Basic: $79 per employee per month
- PEO Plus: $124 per employee per month
- Dedicated HR Consulting add-on: $30 per employee per month
- Employer of Record service: $599 per employee per month for international employment
Health insurance, benefit elections and other add-ons can change the final invoice.
Example PEO Budgets Using Published Rates
| Employees | Justworks PEO Basic at $79 | Justworks PEO Plus at $124 |
|---|---|---|
| 10 employees | $790 monthly, $9,480 annually | $1,240 monthly, $14,880 annually |
| 25 employees | $1,975 monthly, $23,700 annually | $3,100 monthly, $37,200 annually |
| 50 employees | $3,950 monthly, $47,400 annually | $6,200 monthly, $74,400 annually |
These figures show the published administrative rates only. They are not guaranteed all-in employment costs.
How Much Does Fractional or Outsourced HR Support Cost?
Outsourced HR consultants and fractional HR managers generally charge between $500 and $7,000 per month, depending on the level of responsibility.
Published 2026 pricing for small employers lists these common service levels:
- Administrative-only HR support: $500 to $1,500 per month
- Senior HR advisory support: $1,000 to $6,000 per month
- Fractional HR leadership: $4,000 to $7,000 per month
Administrative support may include payroll coordination, basic compliance tracking and document management. Advisory support adds help with policies, employee relations and difficult workplace decisions. Fractional HR leadership may include ownership of HR priorities, manager support, hiring processes and workforce planning.
This arrangement can suit a company that already has payroll and benefits systems but needs experienced HR advice.
How Much Does Payroll-Only Outsourcing Cost?
Payroll-only outsourcing is usually the least expensive option because it focuses on payroll rather than broader HR management.
Justworks, for example, lists payroll at $8 per employee per month plus a $50 monthly base fee. Its payroll service also supports add-ons such as time tracking and contractor payments.
Payroll outsourcing generally covers:
- Payroll calculations
- Direct deposits
- Payroll tax filings
- W-2 and 1099 preparation
- Payroll reporting
- Basic employee records
Using a payroll provider does not necessarily transfer legal responsibility away from the employer. The IRS states that employers generally remain responsible for payroll tax obligations when they use a third-party payroll provider. A certified professional employer organization may assume certain federal employment tax responsibilities under a qualifying contract, but the agreement should specify who carries each obligation.
What Is Included in the Cost of Outsourced HR?
The price may cover some combination of:
- Payroll processing and tax administration
- Employee onboarding and offboarding
- Employee handbooks and HR policies
- Employment law compliance support
- Benefits administration
- Workers' compensation administration
- Employee relations advice
- Performance management
- HR technology
- Reporting and recordkeeping
- Recruiting or talent management support
A low monthly fee may cover only payroll software and processing. A higher fee may include access to HR professionals, compliance advice, benefits administration and help with employee issues.
Providers use the term "full-service HR" differently, so compare the service scope rather than the monthly price alone.
What Additional Costs Should You Budget For?
The quoted HR outsourcing fee may not include the following:
Health insurance premiums Costs depend on plan design, employer contributions, employee elections, carriers and employee locations.
Workers' compensation Some PEOs include workers' compensation in the service fee. Others list it separately.
Payroll taxes and employee wages These are employment costs, not necessarily part of the provider's outsourcing fee.
Implementation or setup charges Some providers advertise no implementation fee. Others charge for data migration, setup or onboarding.
Optional HR services Recruiting, dedicated HR consulting, advanced time tracking, employment law support and employee training may cost extra.
Minimum monthly charges A provider may impose a minimum fee even if the company has only a few employees.
Termination or transition costs Review the agreement for notice periods, offboarding fees and data-export requirements.
To compare providers properly, separate the administrative fee from pass-through employment costs. ADP recommends reviewing benefits, workers' compensation, HR systems, broker fees and internal administrative time as part of the total cost.
Is Outsourcing HR Cheaper Than Hiring an Internal HR Employee?
Outsourcing HR is often cheaper for a small business that needs professional HR support but does not need a full-time HR department. It is not automatically cheaper for a larger company with a complex workforce.
Compare the following costs:
- Outsourced HR fees
- Internal HR salaries and benefits
- Payroll and HR software
- Benefits administration
- Legal and compliance support
- Workers' compensation administration
- Recruiting and employee-relations workload
- Management time spent handling HR tasks
The National Association of Professional Employer Organizations reports a 27% return on investment from PEO use based on cost savings. That figure is an industry benchmark, not a guarantee for every business.
Which HR Outsourcing Option Makes the Most Financial Sense?
The best option depends on the work you need to transfer and the responsibility you want to keep internally.
Choose Payroll Outsourcing When:
- You only need payroll processing and tax filings.
- Your managers already handle employee issues.
- You manage your own HR policies and compliance.
- You do not need group benefits through a provider.
Choose an Outsourced HR Consultant When:
- You need help with policies, employee relations or compliance.
- You want experienced HR advice without hiring a full-time HR manager.
- You already have payroll and benefits systems.
- You want a flexible monthly retainer.
Choose a PEO When:
- You want payroll, HR, benefits and compliance in one arrangement.
- You have employees in multiple states.
- You need workers' compensation administration.
- Access to broader employee benefits matters to your hiring plans.
- You prefer a per-employee monthly cost.
Choose an Employer of Record When:
- You need to hire employees in another country.
- You do not have a legal entity in the employee's country.
- You need local payroll, employment contracts and compliance administration.
An Employer of Record generally costs more than domestic HR outsourcing because the provider becomes the worker's legal employer. Justworks, for example, publishes an EOR price of $599 per employee per month.
Bottom Line
Outsourcing HR is not one service with one standard price. Payroll-only support may be enough for a company that already handles employee issues internally. A consultant or fractional HR leader is a better fit when the business needs HR judgment without a full-time hire. A PEO makes more sense when payroll, benefits, compliance and workers' compensation need to operate under one arrangement.
