Absence Rates Turnover (Individual) Calculator
Calculate an individual employee's absence rate, attendance rate, absence frequency and annualised absence days from their scheduled working time.
Overview
Use this individual absence calculator to compare absence days with scheduled workdays, see attendance and absence rates, and project the observed pattern across a full working year. It also shows how often absence occurred and the average length of each absence spell.
How it works
The calculator divides absence days by scheduled workdays to calculate the individual absence rate. Attendance is the remaining proportion of scheduled days. It also divides absence occasions by scheduled workdays and scales both the day and occasion results to the annual workday figure you enter. Annualised figures are projections, so a short review period may not reflect the full year.
How to use this calculator
- 1Enter the number of workdays the individual was scheduled to work during the review period.
- 2Add the total scheduled workdays missed through absence.
- 3Enter the number of separate absence occasions recorded in the same period.
- 4Set the individual's usual number of scheduled workdays in a full year.
- 5Review the absence rate, annualised absence days and absence frequency.

Individual absence rate
7.7%
With 10 absence days from 130 scheduled workdays, the individual absence rate is 7.7%. If this pattern continued across 260 annual workdays, this would equate to about 20.0 absence days and 6.0 absence occasions per year.
Frequently asked questions
How is an individual absence rate calculated?
Divide the individual's absence days by their scheduled workdays for the same period, then multiply by 100. For example, 10 absence days out of 130 scheduled days is a 7.7% absence rate.
Should holidays be included in scheduled workdays?
Usually no. Use the workdays the person was expected to work in the review period, excluding annual leave, public holidays and other non-working days according to your organisation's policy.
What is an absence occasion?
An absence occasion is one separate spell of absence. For example, three non-consecutive sickness spells are generally recorded as three occasions, even if some last more than one day.
What does annualised absence mean?
Annualised absence projects the absence pattern seen in the review period across the individual's full-year scheduled workdays. It is an estimate, not a prediction.
Can this calculator be used for part-time employees?
Yes. Enter the part-time employee's actual scheduled workdays in both the review period and their usual full working year. This makes the rate relative to their own working pattern.
Is absence rate the same as employee turnover?
No. Absence rate measures time missed by an individual who remains employed. Employee turnover usually measures people leaving an organisation over a period.
