Bradford Factor Calculator
Did you know that over a year, absence patterns can:
Turn 10 days off into a score of 1,000
When absences are spread across 10 separate occasions instead of one.
Multiply absence impact by 25×
Five short absences score 250, versus 10 for one continuous absence.
Be measured over 52 weeks
Most Bradford Scores use a rolling 12-month period.
Trigger reviews from 100+
Many employers monitor Bradford Scores once they pass 100–200.
Highlight repeat short absences
The formula weights frequency, not just total days off.
What Bradford Scores means
Because the formula weights frequency heavily, a low Bradford Score suggests stable attendance with fewer interruptions, while a high score can indicate patterns worth reviewing within HR absence management.
Common Bradford Score interpretations
- 0–50: Generally considered low and normal absenteeism
- 51–100: Possible area for monitoring
- 101–200: High or concerning patterns
- 200+ : Very high, may prompt formal discussion or review
How Bradford Score is calculated
Bradford Score = S² × D
S = number of separate absence spells within the period
D = total days absent in that same period (often a rolling 12-month window)
Why Bradford Scores matter for your business
Frequent short-term absences can cause more disruption than longer, planned time off. Without clear visibility, patterns often go unnoticed until they escalate.
