Definition
This is the percentage of Available Service Hours spent on delivering billable Service Hours.
Formula
Billable Utilisation = Service Hours / Available Service Hours (from Allie Timesheet) x 100
Example
Allie, a practitioner, completed 25 Service Hours over the time period in review (e.g. 1 week). From the entries made into the Timesheet, Allie has 38 Ordinary Hours i.e. Paid Working Hours, however after adjusting for time where Allie was unable to provide billable service to clients, Allie now has a total of 32 Available Service Hours during the week. Allie's Billable Utilisation can be calculated as:
Billable Utilisation: [25] / [32] x 100 = 78%
Note: Billable Utilisation takes into account the number of hours where a practitioner is unable to perform Service Hours i.e. it subtracts non-billable time from Paid Working hours to account for activities like Mentoring, Training, CPD, Breaks and Leave so that your reference point for Utilisation is the 'Available Service Hours'.
