Absence Rates Rate (Individual) Calculator
Calculate an individual's absence rate as a percentage of their scheduled working days over a selected period.
Overview
Use this Individual Absence Rate Calculator to measure the percentage of scheduled working days an individual missed through absence. Enter the scheduled workdays and absence days for the same week, month, year, or custom period to see the absence and attendance rates.
How it works
The calculator divides the number of absence days by the number of scheduled working days, then multiplies the result by 100. For example, 8 days absent from 220 scheduled workdays gives an absence rate of 3.64%. It also subtracts absence days from scheduled days to estimate days worked and calculates the corresponding attendance rate.

Frequently asked questions
How is an individual absence rate calculated?
Divide the individual's absence days by their scheduled working days for the same period and multiply by 100.
What counts as scheduled working days?
These are the days the person was expected to work under their normal schedule, usually excluding weekends, approved non-working days, and other days they were not required to work.
Can I include half-day absences?
Yes. Enter part-day absences as decimals, such as 0.5 for a half-day or 1.5 for one and a half days.
Should annual leave be included in absence days?
Usually no. Annual leave is normally planned time away rather than absence, but you should follow the definitions used by your organisation.
What is a good absence rate?
There is no single appropriate figure for every workplace. Rates vary by role, working pattern, industry, reporting period, and the absence definitions used.
Why might attendance rate not equal 100% minus absence rate?
In this calculator they are complementary because both use the same scheduled working days. Differences can occur in other reports when they use different definitions or include additional time categories.

Assumptions and warnings
Assumptions
- The scheduled working days and absence days cover the same measurement period.
- Absence is measured in workdays; part-day absences can be entered as decimals.
- Non-working days, such as weekends and contractual days off, are excluded from scheduled working days.
- The result is a simple percentage and does not distinguish between absence reasons or patterns.
Warnings
- This calculator provides a general attendance measure only. Apply your organisation's absence policy and definitions when recording or interpreting results.
- Do not use an absence percentage alone to make employment or wellbeing decisions; consider relevant circumstances and applicable rules.
