Recruitment agency margin calculator: percent, fixed and custom modes
Three ways to apply margin to a proposal and when each makes sense.
Last updated
The margin strip sits at the top of the Roles & Base Pay section in the proposal builder. Three modes: pick the one that matches how this client agreed to be priced.

Percent (the default)
You set a single margin percentage for the whole quote. Bill rate per shift = true cost / (1 - margin%). The simplest mode and what every quote starts in.
Fixed
You set a single £/hr margin for the whole quote. Bill rate per shift = true cost + £fixed. Used when a client has agreed a flat hourly fee rather than a percentage.
Custom (Agency plan and above)
You set a different margin per cell: different per role, different per shift. A common setup is lower margin on the bread-and-butter Day shift, premium margin on Bank Holiday cover. Click the per-shift margin column in the role detail rate card to set overrides.
