Context
- For reporting and planning, use aggregated values where possible, not diagnoses or unnecessary health data.
- For incapacity for work, document eAU status and proof process separately from diagnoses.
- Sickness days are tracked separately and feed into the sickness rate.
- Other absence days are included separately so sickness rate and total rate are not mixed up.
- Cost impact is a scenario based on absence days, hours, wage and employer overhead.
- Sickness during approved leave needs separate treatment if properly certified.
Next steps
- Check whether specific teams, roles or shifts show clusters.
- Document sickness notices and eAU status completely but data-minimally.
- Keep target rate and period consistent for later comparisons.

How the calculator works
From absence days to rate, cost impact and rostering signal
The calculator compares entered absence days with planned employee workdays. That creates the sickness rate and total absence rate for the same period.
It also compares the result with your internal target rate and shows how many absence days sit above that target. This becomes a pragmatic signal for cover planning.
The cost result is a scenario based on absence days, average hours per day, gross hourly wage and employer overhead. It is not payroll advice and does not decide continued-pay obligations.
