How to Read Your Results
Lost workdays are the estimated scheduled employee days unavailable because of absence.
Available workdays show capacity left after the estimated absence loss.
Average available employees is a capacity average, not a daily headcount forecast.
FTE cover is an average over the selected period and may not match the number of people needed on a particular day.
Lost hours are useful when workload, staffing, or service targets are managed in hours.
Assumptions & Important Notes
- Each example applies the absence rate evenly throughout its stated period.
- The working-day figure is specific to the selected monthly, quarterly, or annual period.
- All employees are treated as having the same scheduled days and hours.

Frequently Asked Questions
Can I use the calculator for a week or month?
Yes. Use the average employee count and scheduled working days for that same week or month.
Why can FTE cover be a decimal?
It represents average capacity over a period. For example, 0.5 FTE means capacity equal to half of one full-time role over that period.
Should I round lost workdays?
Keep decimals for planning calculations when useful, then apply your own operational rounding approach.
Can I compare different absence scenarios?
Yes. Run the calculator with different absence rates while keeping the workforce and period consistent.
