Payroll · Compare · Updated August 2026

Every payroll provider advertises a number that is technically accurate and practically incomplete. Here is the full anatomy of a payroll bill, and how to model yours before you sign anything.

The four-layer bill

Payroll pricing looks simple because the first layer is simple. A base fee, a per-person fee, and you are done. In practice a payroll bill has four layers, and only the first appears on the pricing page.

  • Layer 1 — base and per-person. The advertised number. Scales with headcount.
  • Layer 2 — tier cliffs. Step changes triggered by growth events, not by choice.
  • Layer 3 — add-ons and service fees. Registration, time tracking, broker fees, year-end forms, implementation.
  • Layer 4 — global costs. Statutory contributions, deposits, FX spread, country surcharges. Only applies if you cross borders, and then it dwarfs everything above.

Most buyer regret comes from comparing providers on layer one and discovering layers two and three afterwards. This guide walks each layer and ends with a modelling exercise you can complete in about fifteen minutes.

Layer 1: base and per-person

Almost every modern provider charges a fixed monthly base fee plus a recurring fee per person paid. The per-person component is the one that matters, because it compounds while the base fee does not.

ProviderPublished entry priceStructure
Gusto$49/mo + $6 per personThree tiers plus a contractor-only plan
OnPay$49/mo + $6 per workerOne core plan; HR sold as an add-on
Rippling~$8 per employee/mo + base feeCore platform only; payroll priced separately
Deel (global payroll)$29 per employee/moModular by product, per worker
Deel (EOR)$599 per employee/moPer employee, no salary percentage

Two structural details are worth internalising. First, a flat per-person fee is materially better than a percentage-of-salary fee for anyone paying above entry-level wages — percentage models scale with your compensation decisions, which is an odd thing to pay for. Second, published rates move: several providers raised base fees during 2025 and 2026, in one case twice inside twelve months. Verify on the vendor's own page the day you decide, because a large share of comparison content quotes stale numbers with complete confidence.

Where the per-person fee is charged

Read the billing definition, not the marketing. Most providers charge per person paid in a billing period rather than per person on the roster, which means seasonal and irregular workers only cost you in months they are actually paid. Some providers count anyone included in a pay run even at zero earnings — so leaving inactive people checked in a run quietly adds cost.

Layer 2: tier cliffs

This is the layer that generates the most surprise, because a cliff is not something you choose. It is something your growth triggers.

The second-state cliff

The most common and most expensive. On tiered providers, hiring one employee in a second state can force an upgrade that raises the base fee and doubles the per-person charge for everyone, not just the new hire.

Worked through: a twelve-person single-state team on an entry plan at $49 + (12 × $6) pays $121 a month. Hire one remote employee in another state and a tiered provider moves you to $80 + (13 × $12) = $236. The extra person cost $6 of value and $115 of bill. A flat-rate provider that includes multi-state charges $127 for the same change.

Model this before you hire, not after
If distributed hiring is anywhere in your two-year plan, calculate the post-cliff number now and compare providers on that figure. It reverses the ranking surprisingly often.

Other common cliffs

  • Deposit speed. Faster funding is frequently reserved for a higher tier. This matters most for hourly teams with tight cash timing.
  • Custom reporting. Standard reports are universal; flexible or custom reports often sit on the top tier.
  • Priority support. Widely gated, and the gate falls precisely where small employers cannot reach it.
  • Performance and HR modules. Reviews, compliance alerts, and HR advisory access tend to live on premium plans.
  • Headcount minimums. Some enterprise-oriented plans impose a floor that makes them irrelevant below a threshold.

Layer 3: add-ons and service fees

These do not scale predictably, which is why they are easy to omit from a comparison and awkward to discover later.

Line itemTypical treatmentWhat to ask
State tax registrationPer-state service fee, one-timeCost per state, and whether you can self-file free
Time trackingAdd-on or higher tier; sometimes absentNative or integration? What does the integration cost?
Benefits broker feeFree if the provider is your brokerFee to keep your existing broker
Year-end formsIncluded by modern providersPreparation, e-delivery, and printed mailing separately
Amended filingsOften chargeableCost of a correction, and whose error it covers
Garnishment processingIncluded by some, per-item by othersPer-payment fee, if any
ImplementationFree self-serve; real for platformsOne-time fee and realistic time to first run
MigrationStaff-assisted or self-serveWho enters year-to-date data, and who verifies it
SaaS sales taxApplies in some jurisdictionsWhether tax is added to the published rate

Two of these deserve emphasis. Implementation is negligible for self-serve payroll tools and genuinely material for modular platforms, where setup fees scale with configuration complexity and device management turns the project into a project. Migration looks administrative and is actually a risk item: carrying inaccurate year-to-date data forward produces incorrect W-2s months later, when the error is expensive and visible.

The modular-platform problem

Platforms that price by module deserve a specific warning. Their published entry price typically covers a core layer that does not include payroll at all. Payroll, benefits, time, and device management each add their own per-employee charge on top. The entry figure is accurate and describes nothing anyone actually buys.

If you are evaluating a modular platform, the only number worth having is a written quote for the exact module set you will run, at your headcount, with implementation and mid-term headcount pricing spelled out. Anything less is not comparable to a published rate card.

Layer 4: global costs

If everyone you pay is in one country, skip this section. If not, this layer is larger than the other three combined and is almost never included in comparisons.

  • Statutory employer contributions. Employer-side taxes and social contributions add roughly 10–70% on top of gross salary depending on the country. This is not a platform fee — every provider passes it through — but it is the single biggest number in a cross-border payroll budget and it varies enormously by jurisdiction.
  • Security deposits. Employer-of-record providers commonly hold a refundable deposit of around one month's total employment cost per hire before the first payroll, released after offboarding. For ten hires that is substantial working capital locked up exactly when a scaling company can least spare it.
  • FX spread. Cross-border payments convert at a markup above the mid-market rate, typically disclosed as a range rather than an invoice line. On a seven-figure international payroll, the difference between a 0.6% and a 2% spread is a meaningful annual number that never appears itemised.
  • Country surcharges. Complex markets carry fees above the base rate, so a published per-employee figure is a floor rather than a quote.
  • Entity setup. If you incorporate rather than use an EOR, expect substantial one-time legal and registration costs plus ongoing local accounting and filing obligations.
The EOR crossover
At roughly $599 per employee per month, five people in one country is about $36,000 a year in platform fees alone. Below about five employees in a country, EOR almost always wins. Above ten, incorporation usually does. In between, model it properly — and remember own-entity global payroll runs a fraction of the EOR rate once you have incorporated.

Three worked examples

Abstract structure is less useful than arithmetic. Here are three realistic companies and where their money actually goes.

A. Eight people, one state, all salaried

The simplest case, and the one where published pricing tells nearly the whole story. At $49 base plus $6 per person, this company pays $97 a month on either of the main flat-rate options — about $1,164 a year. There are no tier cliffs in play, no registration fees beyond the initial state, and no time tracking requirement.

The decision here is not cost, because cost is effectively identical. It is whether the company wants HR tooling bundled in or prefers stronger support and a simpler product. Anyone spending more than an afternoon on this comparison is over-optimising.

B. Twenty-two people, four states, mixed hourly and salaried

This is where structure dominates. On a flat-rate provider including multi-state, the bill is $49 + (22 × $6) = $181 a month, plus a time-tracking integration since there is no native clock — call it $60 to $100 more. Roughly $290 a month all in, or about $3,500 a year.

On a tiered provider, four states forces the mid tier: $80 + (22 × $12) = $344 a month, with native time tracking included at that tier. Add per-state registration fees as one-time costs. That is roughly $4,100 a year plus registration.

The gap is real but smaller than the headline tier difference suggests, because the flat-rate option needs a second vendor for time. This is exactly why the comparison has to be built around your configuration rather than a pricing page.

C. Forty people, three states, twelve laptops issued, two contractors abroad

Here the payroll subscription stops being the main number. A modular platform running core, payroll, benefits, and device management at a realistic blended rate lands in the low thousands per month. The relevant comparison is not against a cheaper payroll tool but against the current stack: payroll plus a separate HRIS plus a device management tool plus the hours somebody spends reconciling them.

The two international contractors are a separate line entirely, priced per contractor per month on a global platform, and they carry a classification question that costs nothing until it costs a great deal.

What the three examples share
In every case the ranking changed once the configuration was priced rather than the plan. That is the whole argument for modelling: pricing pages compare plans, and you are not buying a plan, you are buying a configuration.

Modelling your real number

Fifteen minutes with a spreadsheet will tell you more than a week of reading comparison articles. Build one row per provider and these columns:

  • Base fee at your target tier
  • Per-person fee × current headcount
  • Per-person fee × projected 24-month headcount
  • Tier change triggered by your most likely growth event, with the recalculated total
  • One-time costs: implementation, registration per state, migration
  • Recurring add-ons: time tracking, broker fee, HR module
  • Annual year-end costs, if billed separately
  • For global: statutory contributions per country, deposit, estimated FX spread

Then compute three totals per provider: monthly cost today, monthly cost after your most likely growth event, and total cost of ownership over 24 months including one-time items. Rank on the second and third numbers, not the first.

What the exercise usually reveals

Three patterns show up repeatedly. Flat-rate providers lose the headline comparison and win the 24-month one whenever multi-state hiring is in play. Modular platforms cost several times their entry price in any working configuration, which is fine if you use the capability and expensive if you do not. And the difference between the cheapest and most expensive credible option for a small business is usually a few thousand dollars a year — real money, but smaller than the cost of one payroll error or one bad migration.

The Kurums verdict
Price the second year, not the first month. Ask every vendor for a written total covering your exact configuration, your projected headcount, and the growth event most likely to change your tier. Providers that publish a complete rate card make this easy; providers that quote everything are asking you to do the work, and the work is worth doing before you sign rather than after.

Frequently asked questions

What is the average cost of payroll software per employee?
For US small businesses, roughly $6 to $12 per person per month on top of a $40 to $80 base fee, depending on tier. Modular platforms land higher once real modules are enabled. Employer-of-record services are an entirely different scale at several hundred dollars per employee per month.
Why did my payroll bill increase without adding anyone?
Three common causes: a base-fee increase by the provider, a tier change triggered by a feature you started using, or an add-on that came off a promotional period. Several major providers raised base fees during 2025 and 2026, in one case twice inside twelve months.
Are payroll providers with no base fee cheaper?
Rarely, past a handful of employees. Removing the base fee usually means a higher per-person rate, which compounds. Model both structures at your actual and projected headcount before assuming.
Is annual billing worth it?
It is usually discounted meaningfully against monthly, but it removes your ability to leave cheaply and often locks a headcount band. If you are confident in the provider after a couple of quarters, take the discount. Not before.
What should I ask about mid-term headcount increases?
On annual contracts, ask specifically how growth past your signed headcount is priced. Companies that skip this question find the additional seats priced at a rate they never negotiated.
Do accuracy guarantees actually pay out?
They generally cover penalties and interest arising from the provider's own filing errors, not from wrong data you supplied. Check whether the guarantee is in the contract or only on a marketing page, and what the claim process looks like.
