Formula
Block capacity = floor((available hours − fixed commitments − buffer time) ÷ (block length + break length)).
How to use this calculator
Enter available time, block size, break size, fixed commitments, and the blocks you want to plan. The calculator compares planned blocks with realistic capacity.
What this calculator includes
- Prevents overplanning.
- Accounts for breaks and buffer, not just raw hours.
- Shows conservative, balanced, and aggressive planning capacity.
- Useful for daily or weekly time blocking.
Tip: Use conservative inputs when planning deadlines or workload. A calculator is most useful when it prevents overcommitment, not when it only confirms an optimistic plan.
FAQ
How many time blocks should I plan per day?
