Track absence days, hours, incidents, and payroll effects. Benchmark trends across teams, months, and schedules. Make smarter staffing decisions using deeper attendance performance metrics.
The calculator uses a responsive grid: three columns on large screens, two on tablets, and one on mobile.
| Metric | Formula |
|---|---|
| Scheduled team days | Average employees × Scheduled workdays per employee |
| Equivalent days lost | Full absence days + (Partial absence hours ÷ Hours per workday) |
| Absence rate | (Equivalent days lost ÷ Scheduled team days) × 100 |
| Incidence rate | (Absence incidents ÷ Average employees) × 100 |
| Prevalence rate | (Employees with absence ÷ Average employees) × 100 |
| Severity rate | Equivalent days lost ÷ Absence incidents |
| Bradford factor | Absence incidents² × Equivalent days lost |
| Loaded hourly cost | Hourly pay × (1 + Benefit load ÷ 100) |
| Estimated total cost | Hours lost × Loaded hourly cost × Indirect multiplier |
| Annualized lost days | Equivalent days lost × (Annual workdays ÷ Period workdays) |
| Item | Example value |
|---|---|

| Indirect multiplier | 1.45 |
| Benchmark absence rate | 3.00% |
| Calculated absence rate | 1.83% |
| Calculated Bradford factor | 40,578.25 |
| Estimated total cost | $12,632.43 |
It measures lost working time against scheduled working time. The result shows how much planned labor capacity disappeared during the period.
Partial hours capture lateness, early departures, and medical visits. Converting them into equivalent days prevents underreporting and improves comparison across teams.
Incidence counts how often absences happened. Prevalence shows how much of the workforce had at least one absence. Together they reveal spread and repeat behavior.
Bradford factor emphasizes repeated short absences. Many separate incidents create a much higher score than one long absence with the same days lost.
Use an internal target, prior-year average, or industry comparison. A stable benchmark helps managers quantify performance gaps and potential productivity recovery.
Yes. It first loads hourly pay with benefits, then multiplies by an indirect factor to approximate overtime, admin effort, and operational disruption.
Yes. Enter period-specific days and absence values. The annualization field then scales results to a yearly view for planning and trend analysis.
Check hotspots by team, schedule, manager, and cause code. Then compare current values against benchmark and focus on repeat-incident patterns first.
