Bradford Factor Calculator
Calculate employee Bradford Factor scores (B = S² × D) to measure workplace absence disruption levels.
What is the Bradford Factor Calculator?
The Bradford Factor calculation measures the operational disruption caused by short-term, frequent employee absenteeism compared to single extended absences over time. It squares the total number of individual absence instances and multiplies the result by the cumulative aggregate days of absence. This equips human resource professionals with an objective scoring index to identify disruptive absence patterns and enforce fair workplace attendance policies.
The Bradford Factor is an established Human Resources formula used to quantify the operational disruption caused by employee absenteeism. The core premise is that frequent, unplanned short-term absences cause significantly greater workplace friction than infrequent, extended medical leaves.
By squaring the number of absence instances (spells), the formula places exponential weight on frequency over total days. Our Bradford Factor Calculator provides instant scoring and categorizes results into standard HR action thresholds.

The Bradford Factor Formula
The score (B) is calculated by taking the square of the number of absence instances (S) and multiplying by total days absent (D) over a 52-week rolling window.
