How to Read Your Results
The absence rate is the percentage of scheduled hours recorded as absence; a lower percentage means fewer scheduled hours were missed.
Estimated attended hours are scheduled hours minus the absence hours entered, not a separate timekeeping verification.
Attendance rate is the percentage of scheduled time not recorded as absence and normally equals 100% minus absence rate.
Compare percentages only where periods, scheduled-hour definitions, and absence categories are treated consistently.
A raw-hour total can be useful for records, while the percentage provides context for different working patterns.
Assumptions & Important Notes
- Each example uses scheduled and absence hours from exactly the same period.
- The examples do not classify absence by cause or entitlement.
- Annual leave, holidays, overtime, and non-working time are assumed to be treated consistently within each example.
- Results are rounded to two decimal places for percentages and may differ slightly from calculations using more decimal places.

Frequently Asked Questions
How do I calculate a four-week absence rate in hours?
Add qualifying absence hours for the four weeks, divide by scheduled hours for those same four weeks, and multiply by 100.
Why can two employees have the same absence hours but different absence rates?
Their scheduled hours may differ. The person with fewer scheduled hours will have a higher percentage for the same number of absence hours.
Can I calculate an absence rate for a custom period?
Yes. Use the scheduled and qualifying absence hours for the exact custom start and end dates.
Should I round absence rates?
Rounding to two decimal places is usually clear for reporting, while retaining unrounded figures in source records can help with reconciliation.
Is estimated attended time the same as confirmed time worked?
Not necessarily. It is the calculator result from scheduled hours less recorded absence hours; separate time records may capture other adjustments.
