Bradford Factor score

63

Early review range

This score is often used as a prompt for an informal review, depending on your organisation's policy.

Formula
3^2 x 7 = 63
Pattern
3 occasions across 7 days

Why repeated short absences score higher

The Bradford Factor gives more weight to repeated absence occasions than to one continuous absence. Two employees can have the same total days absent but very different scores if one absence pattern is more fragmented.

Guide

What is the Bradford Factor?

The Bradford Factor is an absence scoring method used by some employers to highlight frequent short-term absence. It does not measure how ill someone is. It measures the pattern of absence by giving extra weight to the number of separate absence occasions.

In practice, this means one continuous absence usually produces a much lower score than the same number of days split across several separate absences. HR teams often use the score as a trigger for a conversation, support review, or policy checkpoint.

How to calculate it

The formula is S2 x D = B. S is the number of separate absence occasions, D is the total days absent, and B is the Bradford Factor score.

Example 3 occasions x 3 occasions x 7 days = 63

Using the score fairly

Many UK employers use score thresholds as review triggers. The exact trigger points should come from the employer's own policy and should be applied with care. Disability, pregnancy, long-term health, reasonable adjustments, and wider context may all matter.

Questions

Bradford Factor FAQ

What does a Bradford Factor score of 100 mean?

A score of 100 is commonly used as an example trigger for a more formal review, but there is no universal rule. Your organisation's absence policy decides what happens next.

Does the calculator store employee data?

No. This page calculates in your browser and does not ask for names, identifiers, or employee records.

Can half days be used?

Yes. The days absent field accepts half days, so 2.5 days across 2 occasions would calculate as 2^2 x 2.5 = 10.

Should Bradford scores be used automatically?

No. Scores are best treated as prompts for review, support, and consistent decision-making alongside policy and legal obligations.
