Bradford Factor Calculator

Bradford Factor Calculator

The Bradford Factor is a widely used HR absence management formula that deliberately weights frequent, unpredictable short absences much more heavily than one longer, planned absence covering the same total number of days.

B = S┬▓ x D
where S = number of separate absence episodes (spells), D = total days absent

Example

5 separate absence episodes totaling 8 days absent:

B = 5┬▓ x 8 = 200 (high concern - typically triggers formal review)

The Core Insight: Frequency Matters More Than Duration

Consider two employees each absent for exactly 10 days over a year: one takes 10 separate one-day absences (S=10, D=10), scoring 1,000, while the other takes a single 10-day absence for a planned medical procedure (S=1, D=10), scoring just 10. The logic behind this dramatic weighting difference is that frequent, unpredictable short absences typically disrupt team scheduling and workflow coverage far more severely than one absence that can be planned around in advance.

How Organizations Use This Score

Score Range	Typical Interpretation
Under 50	Low concern
50-199	Moderate concern - worth a supportive conversation
200-499	High concern - often triggers formal review
500+	Very high concern

Organizations using this framework typically pair it with supportive conversations rather than purely punitive responses, since frequent absences can also signal an underlying health condition, caregiving burden, or workplace issue worth understanding rather than simply penalizing.
