Payroll outsourcing costs: know what a quote includes.

How much does outsourced payroll cost?

There is no useful universal per-employee price. Quotes depend on what the supplier processes, how frequently employees are paid, the number of PAYE schemes, complexity of pay elements, pensions administration, data quality, support arrangements and onboarding work. A software subscription, a bureau producing calculations and a hands-on managed team are different purchases.

Rather than publish a fictitious fixed tariff, the calculator on this page lets you test transparent planning assumptions. Its figures are scenarios, not our prices or market averages. A real quote requires a work specification.

The charging models you are likely to encounter

Some buyers compare only the headline recurring charge and overlook the other four categories. Ask for the total first-year cost and, separately, the expected cost in year two after onboarding is complete.

Why two businesses with 50 employees receive different quotes

Consider two hypothetical employers, each paying 50 people:

• Employer A has one PAYE scheme, monthly fixed salaries, a single pension scheme, low turnover and consistent data supplied on time.
• Employer B has two PAYE schemes, weekly and monthly pay, overtime, multiple sites, late adjustments, off-cycle payments and detailed department reporting.

The number of employee records is identical. The number of runs, validations, exceptions and interfaces is not. Pricing that ignores those differences either understates the workload or hides limits in the small print.

An example first-year budget—not an offered tariff

Suppose a business wants to model 60 employees × £7 per month plus a £75 administration allowance. That gives £495 per month or £5,940 for 12 months, before onboarding, VAT and exceptional tasks. The choice of £7 and £75 is simply an editable assumption; it is not a verified quote, an industry benchmark or a promised service price.

Now add an illustrative £600 one-off implementation allowance and £300 for a parallel run or additional reconciliation work. The scenario becomes £6,840 in year one, before any VAT and unforeseen changes. A good proposal makes every assumption explicit so a finance lead can replace estimates with signed commercial terms.

Costs that need their own line in a proposal

1. Onboarding: employee master data validation, YTD pay/tax reconciliation, historical information and payroll calendar setup.
2. Non-standard pay runs: emergency corrections, bonuses outside the ordinary run and extra weekly/fortnightly schedules.
3. Complexity: pensions, benefits, statutory payment queries, multiple entities, variable-hour inputs and reports by location or cost centre.
4. Support and exit: payroll query volume, response expectations, data exports, notice periods and final-year reconciliations.
5. Compliance boundaries: who files FPS/EPS, handles HMRC responses, prepares pension files and manages tax advice outside routine calculations.

If a proposal says “all inclusive”, insist on the inclusions in writing rather than treating that phrase as a guarantee.

Use the calculator as a negotiation tool

Change the employee count, assumed per-employee fee and administration allowance below. Copy your chosen assumptions into the initial supplier brief. The tool runs entirely in your browser and does not upload employee information.

When comparing bids, apply the same pay frequencies, same employee counts and same scope to each. Our provider evaluation guide and printable checklist make this easier. For a conversation about your actual requirements, request a written scope.
