Do I need a spreadsheet to track Bradford factor scores?

No. This free tracker does what the downloadable Bradford spreadsheets do, in your browser: one row per employee, the S squared x D calculation, trigger bands at 51, 201 and 401 (all editable), and a rolling 52-week window that updates itself. If you already keep totals in a spreadsheet, import them as CSV and export the scored grid back out. Nothing is uploaded and there is no sign-up.

Where Compono fits

A grid of Bradford scores shows you which absence patterns are disrupting the team, and who is trending towards a trigger. It still cannot tell you why someone keeps taking odd Mondays, or whether they are quietly heading for the door. Existing HR tools track the absences (the process risk). Compono Engage reads the behavioural signals underneath them (the people insight risk), so you can act on the cause while it is still a conversation rather than a resignation. Trusted by government departments and mid-market employers across ANZ, and rated 4.8 out of 5 on Capterra.

How it's calculated

Each person's score uses the standard Bradford Factor formula, B = S squared x D, where S is their number of separate absence spells and D their total days absent across a rolling 52-week window. Squaring the spells is the whole point of the index: five single days score 125, while one five-day illness scores 5, because unplanned odd days are far harder to cover than one known stretch. The tracker applies the common trigger points of 51 for an informal review, 201 for a formal review and 401 for escalation, and you can change all three to match your own absence policy. Enter each person's spell and day totals directly, or open their log and record dated absences; with a log, the tracker counts only the spells that fall inside the last 52 weeks, so scores update themselves as old absences age out. That rolling window is the part a spreadsheet makes you rebuild every month. Everything runs in your browser. Names and absences are never uploaded, stored or seen by us; the grid is saved on your own device so it is still here next month.

Common questions

What are the standard Bradford Factor trigger points?

The convention used widely across UK and ANZ HR practice is 51 for an informal review, 201 for a formal review and 401 for escalation. They are a starting point, not a standard anyone audits you against, so the tracker lets you set all three to match your own absence policy. Lower scores are better; under 51 is generally treated as no concern.

How does the rolling 52-week window work?

The Bradford Factor is measured over the last 52 weeks, not a calendar year. When you record dated absences in someone's log, the tracker counts only the spells that started inside the last 365 days, so a bad patch two winters ago stops inflating their score automatically. Older entries stay in the log for reference but are excluded from the calculation. This is the piece spreadsheets handle worst, because someone has to rebuild the window by hand every month.

Is my team's absence data uploaded anywhere?

No. The tracker runs entirely in your browser, and nothing you type is sent to Compono or anyone else. The grid is saved on your own device (using your browser's local storage) so your team is still here when you come back, and the Clear all button removes every trace. The share buttons only ever share aggregate numbers, never names.

Can I import my existing absence spreadsheet?

Yes. Export it as CSV with columns for name, absence spells and days absent (the tracker recognises common headings like "occasions" and "total days", and copes with quoted names). Rows are added to the grid and scored immediately. You can export at any time, and the export includes each person's score and band so it files neatly with your absence records.

Should I discipline someone over a high score?

No, a high score is a signal to start a supportive conversation, not an automatic disciplinary step. Genuine illness, caring responsibilities and disability-related absence all need care, and much of it should sit outside what the score drives. Blind trigger-pulling on Bradford scores is how organisations end up penalising their sickest people. Use the grid to spot patterns worth understanding, then talk to the person.
