Step-by-Step Calculation
Calculate the daily salary value
The annual gross salary is spread evenly across the entered working days.
dailySalary = annualSalary / workingDaysPerYear
Calculate the absence rate
This shows total absence as a percentage of the annual working days.
absenceRate = (absenceDays / workingDaysPerYear) * 100
Find unpaid absence days
Fully paid days are removed from total absence. The result cannot be below zero.
unpaidAbsenceDays = max(0, absenceDays - paidAbsenceDays)
Estimate the gross reduction
Each unpaid day is valued at the estimated gross daily salary.
estimatedSalaryReduction = dailySalary * unpaidAbsenceDays
Estimate salary after absence
The estimated gross reduction is deducted from annual salary.
estimatedSalaryAfterAbsence = max(0, annualSalary - estimatedSalaryReduction)
Example: eight absence days with three paid days
Daily salary value
52,000 / 260
$200 per day
Absence rate
(8 / 260) * 100
3.08%
Unpaid absence days
max(0, 8 - 3)
5 days
Estimated salary reduction
200 * 5
$1,000
Estimated salary after absence
52,000 - 1,000
$51,000
Final Result
The absence rate is 3.08%, and the estimated gross salary reduction is $1,000.

Common Mistakes to Avoid
Using calendar days instead of personal working days.
Including annual leave when it is not counted as absence under the relevant reporting definition.

Frequently Asked Questions
How is an individual absence rate calculated?
Divide total absence days by working days per year, then multiply by 100.
How is unpaid absence calculated?
It is total absence days minus absence days paid in full, with a minimum result of zero.
Does paid absence affect the absence rate?
Yes. It remains part of total time absent, so it affects the absence rate, but it does not create a reduction in this estimate.
Is the salary reduction net pay?
No. It is an estimated gross salary amount before deductions.
