Bradford Factor

Click or type in the boxes provided to get your Bradford Factor score.

The Bradford Factor is a simple formula to apply a relative weighting to unplanned absences. A higher score suggests that the level of absence could be having a larger impact on your business.

But remember, not all absences are equal! Bradford Factor scores shouldn’t be used as a hard metric for making disciplinary decisions.


We encourage you to think of it as a tool to help you spot potential issues within your teams and ensure they get the support they need.

Calculate the Bradford Factor

How it works

Absence count:

The total number of spells of absence in a given timeframe (normally a rolling 12 month period)

Days absent: 
The total number of days of absence for the same period

E.g. A spell of 2 days absent then a spell of 3 days absent = absence count of 2 and days absent count of 5.
