By Alex Diaz · How we calculate this

Payroll providers typically charge a base fee of $30 to $60 a month plus $4 to $12 per employee, so the bill for a two-person shop looks nothing like the bill for a twenty-person one. What you're really buying is protection from your own mistakes: a missed federal deposit deadline or a mis-calculated withholding can trigger IRS penalties that dwarf a year of software fees, which is the main reason so many small businesses outsource this instead of running it themselves in a spreadsheet.
These key factors affect payroll service affordability
Number of employees and pay frequency
Headcount drives the bill more than anything else in the pricing structure. A solo owner-operator pays close to just the base fee; a ten-person crew adds $40 to $120 a month on top of it. Some providers also charge per pay run rather than a flat monthly rate, so switching from biweekly to weekly payroll quietly doubles that portion of the cost.
Add-on services
Tax filing, HR advisory, benefits administration, and time-tracking integrations get sold separately from basic payroll processing more often than not. A company that just needs paychecks cut can end up paying for an HR helpline nobody calls. The tax filing add-on is worth scrutinizing closely though, since it's the piece that actually protects against IRS and state penalties for late or incorrect deposits.
Contractor vs. employee mix
A business paying mostly 1099 contractors can often get by on a stripped-down, cheaper tier, since there's no withholding to calculate and no employer-side payroll tax to remit. Add W-2 employees and the price climbs alongside the compliance burden, because now someone has to get federal and state withholding right every single pay period.
How to use your results
- Adjust the per-employee fee to match your actual headcount, since it scales the total more than the base fee does.
- Add only the specific add-ons you'd actually use, like tax filing or HR support, rather than a full bundle.
- Compare a contractor-only plan against a full employee payroll plan if your team is mostly 1099 workers.
Ways to make a payroll service more affordable
- Choose a provider with a low base fee if you only have a handful of employees.
- Add only the specific add-ons you need, such as tax filing, instead of a full HR suite you won't use.
- Pay annually instead of monthly where a provider offers a discount for upfront payment.
- Consider a simple spreadsheet plus a low-cost tax-filing service if you have very few employees and simple needs.
