About this tool
This payroll cost calculator helps businesses estimate the total annual cost of their payroll solution. It combines direct provider fees (base fee, per-employee charges, additional monthly fees, and year-end fees) with the indirect cost of internal administrative time. It does not calculate employee wages, tax withholding, workers' compensation premiums, or legal compliance liability. All outputs are estimates based on the values you enter.
Estimates only. This calculator produces approximate figures based on the values you enter. It does not calculate tax liability, employee withholding, workers' compensation premiums, or legal compliance. Actual costs vary by provider, services, and business.

How payroll service costs are calculated
Payroll providers use several pricing models. The most common is a base fee plus a per-employee charge. Some providers charge per payroll run, meaning weekly payroll (52 runs per year) costs more than monthly payroll (12 runs per year). Others bundle features into tiered plans or quote individually based on size and complexity. The calculator above uses the base-plus-per-employee model so you can model your own numbers.
The formula behind the estimate is straightforward: (Base fee per run + Employees × Per-employee fee) × Runs per year + Additional monthly fees × 12 + Year-end fees equals your estimated annual provider cost. Adding Admin hours per run × Runs per year × Hourly value gives the estimated annual administrative labor cost. The sum is your combined annual payroll administration cost.
What this calculator does and does not do
It does: estimate direct provider fees and internal administrative labor cost based on values you enter, and show cost per employee and per payroll run.
It does not: calculate employee wages, tax withholding, payroll tax liability, workers' compensation premiums, insurance premiums, or legal compliance liability. Those depend on factors outside this tool's scope.

Payroll cost calculator FAQs
How much do payroll services cost?
Payroll services are commonly priced using a base fee plus a per-employee charge, though some providers charge per payroll run or by service package. The total cost depends on the number of employees, payroll frequency, tax filing, year-end forms, and optional services like timekeeping, HR tools, and workers' compensation integration. Use the calculator above to estimate your combined annual cost.
How is payroll pricing calculated?
Most providers calculate pricing as a monthly base fee plus a per-employee fee, with additional charges for year-end forms, tax filing, or add-on services. Some charge per payroll run instead of monthly. To compare providers accurately, calculate the total annual cost including all fees rather than relying on the advertised starting price.
How much does payroll cost per employee?
Per-employee payroll fees vary by provider and service level. To find your effective cost per employee, divide your total annual payroll cost (provider fees plus internal administrative labor) by your number of employees. The calculator above computes this automatically from the values you enter.
How can businesses compare payroll providers?
Compare the total annual cost — not just the base price. Include base fees, per-employee charges, payroll frequency impact, year-end fees, and add-ons for timekeeping, HR, and tax filing. Also ask how pricing may change after introductory promotions and in future years. A lower base price can cost more overall if it requires more internal administrative time.
What payroll fees should businesses look for?
Ask about setup fees, per-payroll-run charges, per-employee fees, direct deposit fees, tax filing fees, local tax filing, year-end W-2 and 1099 processing, garnishment administration, timekeeping, HR tools, benefits administration, workers' compensation integration, additional users, and cancellation or termination fees.
Why does administrative time matter when calculating payroll cost?
The true cost of payroll includes the internal time your team spends managing it — entering time, fixing errors, answering employee questions, and reconciling with accounting. A lower-cost payroll system that requires more manual work can actually cost more overall. The calculator estimates this administrative labor cost alongside provider fees.
