Absence Rates Job Offer (Individual) Calculator
Calculate an individual’s absence rate, attendance rate and annualised absence days for a job-offer or employment review period.
Overview
Use this calculator to turn an individual’s recorded absence into an absence percentage for a job-offer or employment review. Enter the review length, scheduled working days, days absent and number of absence episodes to see absence, attendance and annualised figures.
How it works
The absence rate is calculated by dividing days absent by scheduled working days, then multiplying by 100. Attendance rate is the remaining percentage. Annualised absence days scale the recorded days to a 12-month period, which can help compare review periods of different lengths. The episode figure shows the average number of days in each absence occasion, but it does not explain the reasons for absence.

Frequently asked questions
What is an individual absence rate?
It is the percentage of scheduled working days that an individual was absent during a defined review period.
How is the absence rate calculated?
Divide the number of recorded absence days by scheduled working days, then multiply the result by 100.
Should annual leave be included as absence?
No. Scheduled annual leave is normally excluded from both absence days and scheduled working days for this type of calculation.
Why use scheduled working days rather than calendar days?
Scheduled days reflect the days the person was expected to work, making the result more meaningful for different work patterns.
What does annualised absence mean?
It converts absence in a shorter or longer review period into a 12-month equivalent at the same observed rate. It is a comparison tool, not a forecast.
Can an absence percentage be used alone to make a job-offer decision?
No. A percentage does not show the circumstances, pattern, policy context or any relevant protections that may need to be considered.

Assumptions and warnings
Assumptions
- Scheduled working days accurately reflect the individual’s contracted or rostered workdays during the review period.
- All absence days are measured consistently as workdays or part-days, not calendar days.
- Annualised absence is a simple projection based on the review period and does not predict future attendance.
- The calculation does not distinguish between types, causes or protected categories of absence.
Warnings
- This calculator provides an administrative estimate only and should not be the sole basis for a job-offer or employment decision.
- Absence records should be considered in context and in line with applicable employment, equality, privacy and data-protection requirements.
