How to use this calculator
- Enter the number of team members.
- Add monthly work hours per person.
- Enter combined meeting and admin hours for the team.
- Add interruption or context-switching hours, then calculate.
Measure how much real focus time your team has after meetings, admin work, and interruptions. Use it to estimate lost productivity, focus rate, and practical changes that can create more deep work time.
A higher focus rate means more of the team schedule is available for meaningful execution rather than coordination, interruptions, or overhead.
Use this as a planning estimate. It is most useful when meeting and interruption hours are tracked consistently across the same month.
With 8 team members at 160 hours each, total team capacity is 1,280 hours. If meetings/admin take 260 hours and interruptions take 90 hours, focus time is 930 hours and the focus rate is 72.66%.
Many teams should aim for at least 60% of available time to remain usable for focused execution.
A strong team focus rate is usually 70% or higher, while anything below 45% suggests heavy coordination drag.
Meetings reduce focus time by consuming shared hours and by creating context switching before and after the meeting block.
Start by reducing recurring meetings, protecting focus blocks, and moving simple updates to async channels.
Interruption time should stay low enough that it does not consume more than 10% to 15% of total available team hours.
