All pricing reflects publicly listed or third-party-verified 2026 rates as of July 2026; ADP RUN and Paychex Flex mid-to-top tiers are quote-based, so figures shown are documented starting estimates that vary by headcount, state footprint, and payroll frequency.
TL;DR — Quick Verdict
- The base-fee-plus-per-employee model dominates: expect a $17–$180 monthly base fee plus $4–$22 per employee per month depending on vendor and tier.
- For a 10-person single-state team, OnPay and Gusto Simple both land near $109/month; Patriot Basic runs $57/month; ADP RUN Essential estimates near $119/month before add-ons.
- Gusto raised its Simple base fee from $40 to $49 in March 2026; OnPay moved to $49 base; QuickBooks Payroll per-employee fees rose on July 1, 2026.
- Transparent flat-rate vendors (OnPay, Patriot, Gusto) publish exact prices; ADP RUN and Paychex Flex require sales quotes, and reported all-in costs run $100–$300/month for small teams.
- Recommendation: price-sensitive single-state teams should shortlist Patriot or OnPay; QuickBooks Online users should weigh QuickBooks Payroll for integration; multi-state or benefits-heavy teams should compare Gusto Plus against an ADP RUN quote.
Payroll software rarely costs what the homepage banner implies. A vendor advertising a $49 base fee is quoting the floor, not the ceiling — the number climbs with every employee, every extra state, and every add-on module. Across the six vendors small businesses shortlist most, monthly base fees in 2026 span $17 to $180, and per-employee charges range from $4 to $22, according to published pricing pages from Gusto, OnPay, Patriot, Intuit’s QuickBooks, and third-party pricing surveys of ADP RUN and Paychex Flex. That spread means a 25-person company can pay anywhere from roughly $137 to $730 per month for functionally similar single-state payroll.
This comparison breaks down what each vendor charges, models real monthly totals at three team sizes, and identifies which platform wins for which situation. You’ll see where flat-rate pricing beats tiered pricing, why quote-based vendors like ADP obscure their true cost, and the specific add-ons that quietly double a payroll bill. Understanding these numbers matters because payroll cost is recurring overhead — a $60 monthly difference compounds to $720 a year, every year.
What Payroll Software Actually Costs in 2026
Nearly every small-business payroll platform uses the same skeleton: a fixed monthly base fee plus a per-employee, per-month charge. The base fee covers the platform and tax-filing engine; the per-employee fee scales with headcount. Where vendors diverge is in what the base fee includes and whether they publish the number at all.
Sources: vendor pricing pages (Gusto, OnPay, Patriot, Intuit QuickBooks) and third-party pricing surveys for ADP RUN and Paychex Flex, compiled July 2026. ADP RUN base/per-employee figures are documented estimates — ADP does not publish RUN rates (verify at adp.com). QuickBooks per-employee fee reflects a July 1, 2026 increase (verify at quickbooks.intuit.com/payroll/pricing).
Two 2026 price movements matter for anyone budgeting now. Gusto lifted its Simple base fee from $40 to $49 in March 2026 — an added $108 per year before any per-employee charges. Intuit raised QuickBooks Workforce per-employee pricing effective July 1, 2026, with a six-month price-protection window for new subscribers, which is why the per-employee figure appears as a range rather than a single number.
Real Monthly Cost at 5, 25, and 50 Employees
Base-fee-plus-per-employee math produces sharply different totals depending on headcount. A vendor with a low base fee but a high per-employee charge loses its advantage as the team grows; the reverse holds for high-base, low-per-employee vendors. Below is the modeled monthly cost for single-state payroll, using each vendor’s entry-level published or estimated rate.
Modeled figures calculated by Real Cost Report from each vendor’s entry-tier base and per-employee rate; single-state payroll, add-ons excluded. ADP RUN reflects third-party estimated rates (verify at adp.com).
Notice the crossover. At 5 employees, Patriot Basic ($37) undercuts ADP RUN ($99) by nearly two-thirds. But ADP RUN’s low $4 per-employee rate means that by 50 employees it slots into the middle of the pack at $279 — cheaper than Gusto Simple or OnPay at that size. High base fees hurt small teams; high per-employee fees hurt large ones. Patriot’s low $4 per-employee charge keeps it the cheapest option at all three sizes shown. These totals exclude tax-filing tier differences: Patriot’s $17 Basic plan requires you to file your own payroll taxes, a responsibility that shifts the real cost calculus toward comparing a CPA, bookkeeper, or DIY approach before committing.
Flat-Rate vs Quote-Based Pricing: Which Wins?
The sharpest divide in payroll software isn’t feature depth — it’s pricing transparency. OnPay, Patriot, Gusto, and QuickBooks publish exact rates you can model in a spreadsheet before signing. ADP RUN and Paychex Flex (beyond the entry tier) route you to a sales representative, and the quoted number reflects headcount, payroll frequency, state count, and how well you negotiate.
Transparent flat-rate pricing lets you forecast payroll overhead to the dollar. OnPay charges a single $49 base plus $6 per employee with every feature — tax filing, benefits administration, HR tools — included, no tier upsells. Quote-based pricing trades that predictability for potential volume discounts: ADP’s retention team reportedly offers 10–15% discounts to prevent switching, and multi-state enterprises may secure per-employee rates unavailable on published plans. The catch is that reported ADP RUN all-in costs land at $100–$300 per month for small teams once implementation fees, per-payroll-run charges, and add-on modules stack up — well above the ~$79 base estimate.
Verdict
For businesses under 25 employees running single-state payroll, transparent flat-rate vendors (OnPay, Patriot, Gusto) win decisively — you know the exact cost, there’s no annual contract, and no negotiation is required. Quote-based ADP RUN and Paychex Flex earn their place only for multi-state operations, 50-plus headcounts, or businesses needing bundled PEO and advanced HR, where volume pricing and dedicated support can offset the opacity. If you can model your cost on a published page, that predictability is worth more than a speculative discount.
The Add-Ons That Quietly Double Your Bill
Sticker price is the starting line. The features most growing businesses actually need frequently sit outside the base plan, and they compound fast. Benefits administration add-ons alone can run $10–$30 per employee per month on some platforms — enough to turn a $49 base plan into a $100-plus monthly spend.
Multi-state payroll is the most common trap. On Gusto’s Simple plan, hiring one employee in a second state forces an upgrade to Plus, doubling the per-employee fee from $6 to $12 and adding state registration costs. A 20-person distributed team can jump from roughly $169 to $320 per month overnight. QuickBooks Payroll Core and Premium similarly charge extra per additional state filing, though the Elite tier folds multi-state support into its higher base. Understanding how state and federal tax obligations differ is essential before you assume a single-state price will hold.
Time tracking, priority support, and workers’ comp integration each carry separate charges on most tiered platforms. Payroll frequency matters too: ADP charges per payroll run rather than a flat monthly fee, so weekly payroll (52 runs a year) can nearly double annual processing cost versus biweekly (26 runs). Businesses paying 1099 contractors alongside W-2 staff should confirm contractor handling — misclassifying a worker carries tax and penalty exposure that dwarfs any software fee, and getting 1099 versus W-2 classification right is a prerequisite before payroll setup.
What Most People Get Wrong About Payroll Software Cost
Three mistakes recur when businesses shop for payroll platforms, and each one inflates the true cost.
Mistake 1: Comparing base fees instead of all-in cost at your headcount. A $17 base looks cheaper than a $49 base until you run the per-employee math. The consequence is choosing a plan that costs more at your actual team size. The fix: always calculate base fee plus (per-employee rate × headcount) before comparing, as the modeled tables above demonstrate.
Mistake 2: Assuming the promotional rate is the real rate. Several vendors advertise 50%-off-for-three-months or “three months free” promotions. The consequence is a budget shock at month four when the full rate kicks in. The fix: model your total cost of ownership at the standard rate, never the promo, since the promo expires and the ongoing rate is what you actually pay long term.
Mistake 3: Ignoring self-service versus full-service tax filing. Patriot’s $17 Basic plan requires you to file your own payroll taxes; the $37 Full Service plan files them for you. The consequence of picking the cheaper tier without noticing is unexpected administrative burden — or missed filings and penalties. The fix: confirm whether the plan files federal, state, and local taxes automatically, and weigh the labor cost of doing it yourself. For businesses tracking quarterly obligations, aligning software choice with your estimated tax deadlines prevents both surprises and penalties.
Which Payroll Platform Is Worth It for Your Business?
The right platform depends on headcount, state footprint, existing accounting software, and how much HR functionality you need bundled. No single vendor wins across every scenario.
If you run single-state payroll for a small, price-sensitive team and are comfortable filing your own taxes, Patriot Basic at $17 plus $4 per employee is the cheapest documented option. If you want full-service tax filing with transparent pricing and no tiers, OnPay’s flat $49 plus $6 model includes benefits and HR tools at the base price — strong for businesses that dislike upsell complexity. Already running QuickBooks Online for accounting? QuickBooks Payroll’s tight integration can justify its $50-plus base despite the July 2026 per-employee increase, since the payroll-to-books sync eliminates double entry.
Growing across state lines or needing deeper HR — performance reviews, dedicated support, onboarding workflows — pushes you toward Gusto Plus ($80 + $12) or a negotiated ADP RUN quote. Multi-state teams above 50 employees should request quotes from both ADP and Paychex and compare the all-in number against Gusto Premium, since volume per-employee rates can flip the math. Before committing, factor payroll software into the broader question of whether a CPA, bookkeeper, or DIY setup fits your stage — the software is one line in a larger accounting-cost decision, and pairing it with the right accounting platform matters as much as the payroll price itself.
Frequently Asked Questions
What is the cheapest payroll software in 2026?
Among vendors surveyed, Patriot Basic Payroll is the cheapest at $17 per month plus $4 per employee, though it requires self-service tax filing. Patriot Full Service, which files taxes for you, runs $37 plus $4. For a 5-person team, that’s $37 or $57 monthly respectively — below OnPay and Gusto Simple, which both start at $79 for five employees.
Why doesn’t ADP publish its RUN pricing?
ADP uses a quote-based model for RUN, directing every prospect to request pricing based on headcount, payroll frequency, and features. Third-party surveys consistently estimate RUN Essential near $79 per month plus $4 per employee, with most small businesses reporting $100–$300 monthly all-in. Only Roll by ADP publishes a fixed rate: $39 plus $5 per employee.
Did payroll software prices go up in 2026?
Yes. Gusto raised its Simple plan base fee from $40 to $49 in March 2026, adding $108 per year before per-employee charges. OnPay moved to a $49 base, and Intuit increased QuickBooks Workforce per-employee pricing effective July 1, 2026, with a six-month price-protection window for new subscribers.
Does adding a second state increase my payroll cost?
Often significantly. On Gusto’s Simple plan, hiring in a second state forces an upgrade to Plus, doubling the per-employee fee from $6 to $12 plus state registration costs. QuickBooks Payroll Core and Premium charge per additional state filing. A 20-person distributed team can jump from roughly $169 to $320 per month with one out-of-state hire.
How We Researched This Article
Real Cost Report compiled 2026 payroll software pricing from vendor pricing pages and third-party pricing surveys during July 2026. Published flat-rate figures for Gusto, OnPay, Patriot, and Intuit QuickBooks Payroll were drawn from each vendor’s official pricing disclosures and cross-checked against multiple independent pricing guides to confirm current rates, including the March 2026 Gusto base-fee increase and the July 1, 2026 QuickBooks per-employee adjustment. For quote-based vendors — ADP RUN and Paychex Flex above the entry tier — we relied on documented third-party estimates from established software-review publications, because these providers do not publish standard rates. Those figures are labeled as estimates throughout and should be treated as budgeting benchmarks rather than guaranteed quotes.
Monthly cost totals at 5, 25, and 50 employees are modeled calculations, not vendor-quoted bundles: we applied each vendor’s entry-tier base fee plus per-employee rate for single-state payroll, excluding add-ons, implementation fees, and promotional discounts. This isolates the recurring core cost so vendors can be compared on equal terms. Modeled figures are explicitly distinguished from measured published rates in every table caption. Limitations: actual costs vary with add-on modules, multi-state filings, payroll frequency, and negotiated discounts, and promotional pricing can temporarily lower first-quarter costs. Readers should request current quotes before purchase.
