View the Bradford factor in a Time Taken report

Adding the Bradford factor to a Time Taken report allows you to easily check which employees have taken multiple periods of time off within a specified period.

The report can take into account absences from a selection of time off policies, such as sick leave, doctor’s appointments and personal days.


What is the Bradford factor?

The Bradford Factor supports the principle that multiple absences have a more significant impact on a business than one or two longer periods of absence within the same period.

It uses a formula that applies a weighting to absences such as sick leave or doctor’s appointments. This creates a score which can be added to a Time Taken report. 

The higher the score, the more concern employers may have about the employee’s performance or risk of attrition.

The Formula

The Bradford factor is calculated using the Bradford Formula: S2 x D = B.

  • S = the total number of separate absences.
  • D = the total number of days of absence
  • B = the Bradford Factor score.

In Q4 2021,

Employee A took a total of 3 sick days off work, all at one time:

  • November 11 till November 13 inclusive.  

Their Bradford factor score will be 12 x 3 = 3.

Employee B also took a total of 3 sick days off work, all separately:

  • October 12.
  • November 12.
  • December 12.

Their Bradford factor score will be 32 x 3 = 27.

So even though both employees took three days off during the period, Employee B has a much higher Bradford score because their three days off were all taken separately

Note: The Bradford factor is calculated cumulatively, irrespective of the number of days taken from different policies.

Example: Calculation with multiple policies

Employee B took a total of 3 sick days off work in Q4, using 3 different time off policies:

  • October 12 - sick day.
  • November 12 - doctor’s appointment.
  • December 12 - personal day.

Their Bradford factor score will still be 32 x 3 = 27.
