HR and Payroll Software Costs (2026): Per Employee Pricing Breakdown#

Payroll errors cost businesses an average of $845 per incident in penalties and corrections. Choosing the right HR and payroll platform is not just a software decision -- it is a compliance decision. Yet most vendors make it surprisingly difficult to understand what you will actually pay.

This guide cuts through the pricing pages and breaks down what HR and payroll software really costs in 2026, from base platform fees to the per-employee charges that scale with your headcount.

Per-Employee Pricing Overview#

Most HR and payroll platforms use a base fee plus per-employee-per-month (PEPM) model. A few charge flat rates at certain headcount tiers. Here is what the major platforms charge in 2026:

| Platform | Base Fee/mo | Per Employee/mo | Payroll Included | Benefits Admin | |----------|-------------|-----------------|------------------|----------------| | Gusto | $40 | $6 | Yes | $6/mo add-on | | Rippling | $35 | $8 | Yes | Included | | ADP Run | $59 | $4 | Yes | Quote-based | | Paychex Flex | $39 | $5 | Yes | Quote-based | | BambooHR | $0 | $8.75 | Add-on ($6 PEPM) | Included | | Justworks | $0 | $59 (PEO model) | Yes | Included | | Paylocity | Custom | $18-$25 | Yes | Included | | Zenefits (TriNet) | $0 | $10 | Add-on ($6 PEPM) | Included |

All prices reflect annual billing. Monthly billing adds 10-20% at most vendors.

What Drives the Real Cost#

The per-employee sticker price is the starting point, not the finish line. Here is where budgets actually land:

Base Platform Fees#

Some vendors charge a monthly base fee regardless of headcount. Gusto charges $40/month, ADP Run charges $59/month. Others like Justworks and BambooHR fold everything into the PEPM rate. For a 25-person company, a $59 base fee adds $2.36 per employee per month to your effective rate.

Payroll Tax Filing#

Every vendor on this list handles federal and state payroll tax filing in their standard plans. Where costs diverge is multi-state payroll. If you have remote employees across 10+ states, confirm whether your plan covers all state filings or charges per additional state. ADP and Paychex include unlimited states. Some smaller platforms charge $10-$20 per additional state per month.

Benefits Administration#

Benefits admin is either included, an add-on, or requires a broker relationship:

| Platform | Benefits Admin Cost | Broker Required | |----------|-------------------|-----------------| | Gusto | $6/employee/mo add-on | No (licensed broker) | | Rippling | Included | No (in-house brokerage) | | ADP | Quote-based | Partner brokers available | | BambooHR | Included in Pro plan | No | | Justworks | Included (PEO model) | No |

If you currently use an external benefits broker, confirm the platform integrates with your broker's carrier connections before switching.

Implementation and Onboarding#

Implementation costs are where sticker shock hits hardest, especially at the enterprise end:

| Company Size | Self-Service Setup | Guided Implementation | Full-Service Migration | |-------------|--------------------|-----------------------|------------------------| | 1-25 employees | $0 (most vendors) | $500-$1,500 | $2,000-$5,000 | | 26-100 employees | $0-$500 | $2,000-$5,000 | $5,000-$15,000 | | 101-500 employees | Not recommended | $5,000-$15,000 | $15,000-$50,000 | | 500+ employees | N/A | $15,000-$30,000 | $50,000-$150,000 |

Gusto and Rippling offer self-service setup for small teams at no cost. ADP and Paychex typically include guided onboarding but charge for historical data migration and custom configurations.

Total Cost of Ownership by Company Size#

Here is what a typical company pays annually, including base fees, PEPM charges, and standard add-ons:

| Company Size | Budget Option | Mid-Range | Premium | |-------------|---------------|-----------|---------| | 10 employees | $1,440/yr (Gusto Simple) | $2,280/yr (Rippling) | $7,080/yr (Justworks) | | 25 employees | $2,280/yr (Gusto) | $4,200/yr (Rippling) | $17,700/yr (Justworks) | | 50 employees | $4,080/yr (Gusto) | $7,200/yr (Rippling) | $35,400/yr (Justworks) | | 100 employees | $7,680/yr (Gusto) | $13,200/yr (Rippling) | $70,800/yr (Justworks) | | 250 employees | Custom pricing | $30,000-$60,000/yr | $75,000-$150,000/yr |

The Justworks PEO model looks expensive on a per-employee basis, but it bundles workers comp, benefits, and HR compliance into one fee. For companies that would otherwise pay for those services separately, the effective premium shrinks significantly.

Hidden Costs to Watch For#

Year-over-year price increases. Most HR platforms increase PEPM rates 5-10% annually. Lock in multi-year pricing if your vendor offers it.

Contractor payments. Gusto charges $6/contractor/month for contractor-only payroll. If you use a mix of W-2 employees and 1099 contractors, factor in both pricing tiers.

Time tracking add-ons. Several platforms charge $2-$5 PEPM for built-in time tracking. If you already use a standalone time tracker, confirm the integration is free.

Off-cycle payroll runs. Bonus runs, corrections, and off-cycle payments may incur fees of $10-$25 per run at some vendors. Gusto and Rippling include unlimited off-cycle runs.

Year-end tax forms. W-2 and 1099 generation is included at most vendors, but a few charge $5-$10 per form. Confirm before December.

Which Platform Fits Your Business#

1-25 employees, simple needs: Gusto Simple ($40 + $6/employee) covers payroll, tax filing, and basic HR. It is the most straightforward option for small teams.

10-100 employees, growing fast: Rippling ($35 + $8/employee) scales cleanly and bundles IT device management and app provisioning alongside HR. Strong choice for tech-forward companies.

50-500 employees, compliance-heavy: ADP or Paychex provide deep compliance support, multi-state payroll, and integration with enterprise ERP systems. Expect custom pricing.

Any size, want everything bundled: Justworks PEO model ($59/employee) eliminates vendor sprawl by combining payroll, benefits, compliance, and workers comp into one invoice.

How to Negotiate Better Rates#

1. Get three quotes minimum. HR software pricing is negotiable, especially above 50 employees. Vendors compete aggressively for mid-market deals.
2. Ask for implementation fee waivers. Many vendors waive setup fees for annual commitments or larger headcounts.
3. Request pilot pricing. Some vendors offer discounted rates for the first 3-6 months to reduce switching risk.
4. Bundle modules. If you need payroll plus benefits plus time tracking, negotiate a bundled PEPM rather than paying for each add-on separately.

Frequently Asked Questions#

How much does payroll software cost per employee?#

Basic payroll software costs $4-$10 per employee per month for small businesses. Full HR suites with benefits administration, time tracking, and compliance tools run $15-$25 per employee per month. PEO models that bundle everything including benefits can cost $50-$60 per employee monthly.

Is Gusto cheaper than ADP?#

For companies under 50 employees, Gusto typically costs less than ADP. Gusto's transparent pricing ($40 base + $6/employee) usually beats ADP's quote-based model at small headcounts. Above 100 employees, ADP's volume discounts and enterprise features can make it more competitive.

What is the cheapest payroll software for small business?#

Gusto Simple at $40 + $6/employee/month and Paychex Flex at $39 + $5/employee/month are the most affordable full-service payroll options. Wave Payroll (free in some states) and Patriot Software ($17 base + $4/employee) are budget alternatives with fewer features.

Should I use a PEO instead of payroll software?#

A PEO like Justworks or TriNet makes sense if you want bundled benefits, workers comp, and HR compliance without managing multiple vendors. The per-employee cost is higher ($50-$80/mo) but replaces several separate expenses. PEOs are especially valuable for companies under 100 employees that want access to large-group benefits rates.

How long does it take to switch payroll providers?#

Plan for 4-8 weeks for a clean transition. The best time to switch is at the start of a quarter (January or July) to simplify tax filing. Mid-year switches require your old provider to issue partial-year W-2s and your new provider to handle the remainder.
