School bursar day-rate calculator
Convert an equivalent annual salary into a fractional day rate, with employer National Insurance, employer pension contribution, holiday entitlement, sickness cover and any fractional provider margin layered on top. The output is governor-quotable and includes the comparable in-house permanent total cost of ownership.
Bursar day-rate calculator
For an equivalent annual salary of £60,000 worked across 2 day(s) a week for 46 weeks a year, the comparable day rate inclusive of on-costs is approximately £835.
With a fractional provider margin of 20 percent, the headline day rate the school would pay is approximately £1,002, equivalent to £7,680 a month or £92,160 a year.
The comparable in-house permanent total cost of ownership (salary plus 28 per cent on-costs plus 5 per cent cover allowance) sits at approximately £80,640 a year. The fractional engagement therefore comes out £11,520 above the permanent equivalent.
Note: On-costs include employer National Insurance, employer pension contribution, holiday entitlement, and an allowance for sickness and absence cover.

How the calculation works
The model first converts the equivalent salary into a daily equivalent based on working days a year. On-costs are then layered on, reflecting employer NI above the secondary threshold and an employer pension contribution sized to the scheme in use. A provider margin is layered on where applicable. The comparable permanent TCO assumes 28 per cent on-costs plus a 5 per cent cover and sickness allowance.[1][2]
