Individual Absence Rate Goal Formula
Learn how an individual absence rate, target allowance and remaining absence days are calculated for a work period.
This calculation compares absence days recorded so far with a percentage target for the full work period. It helps estimate the current absence rate, the maximum days implied by the target, and the remaining allowance before the target is reached.

Remaining Absence Allowance
Where:
First convert the target percentage into a maximum number of absence days for the whole period. Then subtract the absence days already recorded.
Variables Explained
| Variable | What It Means | Unit |
|---|---|---|
| totalWorkdays - Total workdays in period | The scheduled workdays in the full period being tracked. | workdays |
| targetAbsenceRate - Target absence rate | The maximum absence percentage for the full period. | percent |
| absenceDaysToDate - Absence days so far | Workdays recorded as absence to date under the applicable workplace policy. | workdays |
| workdaysElapsed - Workdays completed | Scheduled workdays that have passed so far in the period. | workdays |
Step-by-Step Calculation
Calculate the current absence rate
Divide absence days so far by completed workdays, then multiply by 100. The maximum function prevents division by zero before any workdays have elapsed.
(absenceDaysToDate / max(workdaysElapsed, 1)) * 100
Calculate the maximum absence days at the target
Convert the target percentage into a decimal and multiply it by all scheduled workdays in the period.
totalWorkdays * (targetAbsenceRate / 100)
Calculate the remaining absence allowance
Subtract recorded absence days from the target-based maximum. A negative result means the target has already been exceeded.
maximumAbsenceDays - absenceDaysToDate
Calculate workdays remaining
Subtract completed workdays from total workdays. The result cannot be below zero.
max(totalWorkdays - workdaysElapsed, 0)
Calculate the projected final rate with no further absence
Spread the absence days already recorded across the whole period, assuming no additional absence days occur.
(absenceDaysToDate / totalWorkdays) * 100
Example: 3% annual individual absence target
Current absence rate
(2 / 130) × 100
1.54%
Maximum absence days at target
260 × (3 / 100)
7.8 workdays
Remaining absence allowance
7.8 − 2
5.8 workdays
Workdays remaining
260 − 130
130 workdays
Projected final rate with no further absence
(2 / 260) × 100
0.77%
Final Result
The estimated remaining allowance is 5.8 workdays. The current absence rate is 1.54%, and the projected final rate is 0.77% if there are no further absences.
Assumptions
- ✓Absence rate is absence days divided by scheduled workdays.
- ✓The target percentage applies to the entire selected period.
- ✓All entered absence days are counted equally under the same workplace policy.
- ✓The projected final rate assumes no additional absence days are recorded.
- ✓Partial absence days may be entered where the workplace records them.
Limitations
- !Employers may define reportable absence, scheduled days and partial days differently.
- !A calculated decimal-day allowance may be rounded differently in workplace reporting.
- !The calculator does not distinguish between sickness, authorised leave or other absence categories.
- !Future changes to work schedules can change the total number of workdays in the period.
Common Mistakes to Avoid
Using calendar days instead of scheduled workdays.
Entering annual leave or other leave that is not counted as absence under the workplace policy.
Using total workdays in the current-rate calculation instead of completed workdays.
Treating a negative allowance as a number of days still available.
Rounding the target allowance too early before subtracting absence days.

Frequently Asked Questions
How is an individual absence rate calculated?
Divide absence days by completed scheduled workdays and multiply by 100. For example, 2 days over 130 completed workdays equals 1.54%.
How many absence days does a 3% target allow?
Multiply total scheduled workdays by 0.03. Over 260 workdays, a 3% target corresponds to 7.8 days before any workplace rounding.
What does a negative remaining absence allowance mean?
It means recorded absence days are already greater than the amount implied by the target percentage for the full period.
Why is my current rate higher than my projected final rate?
The current rate uses only workdays completed. The projected final rate spreads the same absence days across the full period and assumes no further absence.
