Gusto cost 2026: real per-employee math by plan tier

Total monthly cost by company size

The arithmetic is published, the table below just spares you the calculator. These figures exclude benefits administration, workers' compensation premiums, and any 401(k) administration that runs through Gusto's partners.

When Simple is the right answer

Simple is calibrated for a single-state employer with W-2 employees and not much HR complexity. If you run one office in one state, you pay people on a regular cadence, and you do not need granular time tracking, Simple is genuinely sufficient. Tax filing in all 50 states is included for the state you operate in, year-end W-2s and 1099s ship without a separate fee, and the employee self-service portal handles onboarding paperwork including I-9 and W-4 collection.

The honest weakness of Simple is multi-state. Gusto's own pricing page lists multi-state payroll as a Plus-tier feature. You can technically run multi-state on Simple by registering each state yourself and paying a $12 per-state fee per month, but if you have remote employees in two or more states it is usually cheaper to step up to Plus once you cross three states. At 10 employees with three states, Simple plus $24 in state fees runs $133 per month, versus $200 for Plus. By the time you have five states or two-plus states with at least 15 employees, Plus wins on raw math.

Simple also assumes you are paying employees on a single cadence (bi-weekly or semi-monthly is most common). Mixing cadences (salaried monthly plus hourly weekly) is allowed but creates more touch points. You will not pay more for it, but you will spend more time approving runs.

When Plus actually pays for itself

Plus doubles the per-employee fee from $6 to $12, so the question is what you get for $6 per employee per month extra. The honest answer is four things that are each worth roughly that amount only if you actually use them: native time tracking with PTO management, project tracking for billable-hour businesses, multi-state payroll with proper nexus handling, and next-day direct deposit instead of standard two-day.

A useful test: if you are currently paying for a standalone time-tracking tool at $5 to $8 per employee per month (When I Work, Deputy, Homebase paid tier), Plus collapses that line item plus gives you the rest. For a 15-person professional services firm paying $7 per employee for time tracking, switching from Gusto Simple plus that tool ($49 + $90 + $105 = $244) to Gusto Plus ($80 + $180 = $260) is $16 more per month for a tighter integration plus next-day deposit. Most teams take that trade.

The cases where Plus does not pay off: salary-only teams with no hourly workers, single-state operations, and any team where the existing time-tracking tool is doing project costing or shift scheduling that Gusto's time module does not match.

The Premium tier and the quote process

Gusto Premium is the only Gusto plan that is not openly priced. It is reserved for businesses that want a dedicated customer success manager, a compliance database for HR policy, payroll migration done by Gusto's team rather than your own, and access to a separate health insurance brokerage with priced quotes from multiple carriers. Premium pricing in the wild lands around $180 to $250 base plus $20 to $30 per employee per month for businesses in the 25 to 100 employee band, based on G2 and TrustRadius reviewer reports through Q1 2026.

The number that matters is the comparison: at 50 employees, Plus costs $680 per month, Premium costs roughly $1,180 to $1,750 per month based on reported quotes. The extra $500 to $1,070 buys you the success manager, migration help, and brokerage. For a 50-person company already paying a fractional HR consultant $1,500 per month, Premium can replace that line item and break even. For one that is not, the math rarely works.

Add-ons that change the total bill

The five Gusto integrations that move the per-employee economics are the ones to watch. Guideline 401(k) integration starts at $39 per month for the employer base plus $8 per participating employee per month. For a 25-person company with 60% participation, that is $39 plus $8 x 15 = $159 per month on top of Gusto. Health benefits brokerage is technically free but the premiums pass through, which is fine, but the administrative time you save by having premiums deducted directly from payroll is real.

Workers' compensation via pay-as-you-go integration (NEXT or AP Intego) charges premiums based on actual payroll instead of the upfront annual deposit a standalone broker would ask for. There is no separate platform fee for the integration, only the premium itself, which is rate-based on your payroll and class codes. Commuter benefits administration is $4 per participating employee per month. R&D tax credit help on Premium is included; on lower tiers it is a $500 per filing partner fee through Gusto's third-party integrations.

The honest summary: Gusto's add-on pricing is more transparent than ADP's or Paychex's, but a 25-person company adding 401(k), workers' comp, and benefits brokerage can easily double the base payroll bill. Budget for it.

Gusto vs the obvious alternatives at 25 employees

At 25 employees the cost differences between major providers compress into a narrow band. Gusto Simple at $49 + $6 x 25 is $199 per month. Gusto Plus at $80 + $12 x 25 is $380. Rippling at $35 + $8 x 25 is $235 (without HR or IT add-ons). Paychex Flex at roughly $39 + $5 x 25 is $164, the cheapest of the four, though Paychex pricing requires a quote and the published estimate often understates implementation fees. ADP Run at this size is typically quoted in the $250 to $400 per month range based on G2 reviewer data through Q4 2025.

The 25-employee buyer who picks Gusto Simple over the cheaper Paychex Flex usually does so for the published-pricing transparency and the lack of a contract. Gusto Simple is month-to-month with no cancellation fee. Paychex Flex contracts are commonly 12-month with early termination fees, although the price discount can be 15 to 25%. The trade-off is real and worth doing the math on. Our side-by-side provider comparison spells out the contractual differences in full.

Hidden fees that are not actually hidden

Gusto's reputation for transparent pricing largely holds up. The fees that surprise buyers are usually three: the $12 per-state monthly charge on Simple for any state beyond your primary one, the Guideline 401(k) per-participant fee that is invoiced separately and easy to miss in budgeting, and the optional Gusto Wallet on-demand pay program that has a per-transaction fee passed to the employee but can create perception issues if your team did not expect it.

What is genuinely free that other providers charge for: off-cycle payroll runs, bonus runs, manual checks, employee onboarding, I-9 verification, year-end W-2s, 1099s, contractor payments on the standard plan, and state tax registration in your primary state. Compared to ADP's per-form W-2 charge of $3 to $7 or Paychex's off-cycle run fees, this list is genuinely cleaner. The portfolio hidden fees guide compares all six major providers head to head.
