Calculate employee or team absence rate from missed and scheduled work days.
Absence rate is the single most-tracked HR metric for one reason: it's a leading indicator. By the time engagement scores drop or turnover spikes, you've already lost talent. Absence rate moves first — usually 3 to 6 months before turnover does. Operating it as an early-warning system, rather than a punishment trigger, is the entire difference between an HR team that retains people and one that processes them out.
Absence Rate = (Absent Days ÷ Scheduled Work Days) × 100
Industry standard counts only unplanned absences — last-minute sick calls, no-shows, unscheduled personal days. Pre-approved PTO and vacation are excluded because they're budgeted into the workforce plan. Some organizations track them separately as "approved-time-off rate" for capacity-planning purposes.
| Industry | Avg absence rate | Typical days/yr |
|---|---|---|
| Professional & business services | 2.0% | 5.2 |
| Manufacturing | 3.1% | 8.1 |
| Healthcare | 3.5% | 9.1 |
| Retail & wholesale | 3.7% | 9.6 |
| Education | 4.0% | 10.4 |
| Government | 4.2% | 10.9 |
| Transportation & utilities | 3.8% | 9.9 |
Bradford Factor = S² × D
S is the number of separate absence occurrences; D is total days. A worker with 1 absence of 10 days (S=1, D=10) scores 10. A worker with 5 absences of 2 days each (S=5, D=10) scores 250. The same total time, vastly different patterns. Frequent short absences correlate strongly with disengagement, while a single longer absence is more often genuinely medical. Bradford scores above 100 typically trigger an HR conversation; above 200 typically trigger formal review.
Total cost typically equals 1.5x to 2.5x the direct salary cost depending on industry. Customer-facing and revenue-generating roles carry the highest multipliers.
Industry practice splits on this. Some organizations include FMLA absences (because they affect operations); others exclude them (because they're legally protected and outside the employee's discretion). Be consistent in your tracking method.
Most organizations now treat COVID as standard sick leave for tracking purposes after 2023. Public-health emergency policies have largely sunset.
Yes — intermittent leave is typically tracked in hours rather than days for FMLA compliance. For absence-rate purposes, convert to equivalent days (8 hours = 1 day for full-time employees).
Typically excluded from absence rate — these are protected, scheduled, and not within employee control.
Not in the same way. Gig workers have no scheduled work to be absent from; track "fulfillment rate" or "claim acceptance rate" instead.
Yes — convert their absences to full-time equivalents based on their scheduled hours, or report absence rate separately for full-time and part-time populations.
