How to use this calculator
Enter your available discretionary time, productive time, estimated time leakage, and target productive hours for the same period.
Time leakage can include unplanned browsing, excessive transitions, avoidable waiting, or low-value activities.
What the result means
The result shows productive time as a share of total available time. The target gap indicates how many additional productive hours are needed.
Time Utilization = Productive Time ÷ Available Time × 100
Do not classify necessary recovery, sleep, or restorative leisure as wasted time. Sustainable planning requires recovery capacity.
