Absence Rates Capacity (Team) Calculator FAQ
Answers to common questions about estimating team capacity, absence hours, workdays, and staffing availability.
This FAQ explains the inputs, results, assumptions, and practical uses of a team absence capacity estimate. Results are intended for general planning and should be checked against current schedules and operational information.
General questions
What the calculator estimates and when it can be useful.
What does the team absence capacity calculator do?
It estimates scheduled team capacity remaining after an expected absence percentage is deducted.
Who can use this calculator?
It can be used for general staffing, workload, delivery, and resource planning for a team.
What planning periods can I use?
You can use any whole-week period supported by the calculator, from short plans to longer planning windows.
Is the result a forecast of actual attendance?
No. It is an estimate based on the assumptions and absence rate entered.
Inputs and calculation
How the schedule and absence inputs affect the result.
What should I enter for working days per week?
Enter the usual scheduled workdays per person, adjusted where appropriate for the actual planning period.
How is gross scheduled capacity calculated?
It is team size multiplied by planning weeks, working days per week, and hours per day.
How is expected absence time calculated?
Gross scheduled hours are multiplied by the absence rate expressed as a percentage.
What happens if I enter a 0% absence rate?
Available capacity equals gross scheduled capacity because no absence time is deducted.
What happens if I enter a 100% absence rate?
Available capacity is zero because all scheduled time is treated as absent.
Results and interpretation
How to interpret the outputs without overstating what they mean.
What is available team capacity?
It is the estimated number of scheduled hours remaining after expected absence hours are deducted.
What are available workdays?
They are net available hours expressed as full-day equivalents based on the hours per day input.
Why is average available staffing not a whole number?
It is a full-time-equivalent average. For example, 9.5 represents capacity equal to nine and a half fully available people on average.
Can I convert available hours into tasks or projects?
You can compare hours with estimated effort, but task complexity, skills, dependencies, and non-project work should also be considered.
Accuracy and assumptions
Factors that can make actual capacity differ from an estimate.
Should I include annual leave in the absence rate?
Include it only when the rate is intended to cover annual leave and that leave is not already removed from the schedule.
Do public holidays reduce capacity automatically?
No. Use actual working days for the period or reduce the schedule to reflect public holidays and closures.
Can the calculator handle part-time employees?
It can provide an average-based estimate. For diverse schedules, calculate groups separately for greater accuracy.
Does the calculator allow for meetings and training?
Not automatically. Deduct those commitments separately if they reduce the time available for planned work.
Why can actual capacity be lower than the estimate?
Unexpected absence, vacancies, workload interruptions, unequal skills, handovers, and schedule changes can reduce usable capacity.
How do I calculate team capacity after absence?
Calculate gross scheduled hours, estimate absence hours using the absence percentage, and subtract those hours from gross capacity.
