Constantly jumping between tasks? This calculator quantifies the hidden time and money cost of task switching.
Daily Lost Time = Task Switches Per Day x Refocus Minutes Per Switch
Example
10 task switches per day, 15 minutes to refocus each time, $50/hour value:
Daily Lost Time = 150 minutes (2.5 hours) → $31,250/year
Why Refocus Time Is So Costly
Research on task-switching commonly cites around 15-25 minutes to fully regain deep focus after an interruption - not just resuming the task, but rebuilding the full mental context needed to work at peak effectiveness again.
Why This Matters More Than Raw Hours Worked
This "switching cost" is a major hidden driver of lost productivity that simple hours-worked metrics completely miss - someone at their desk for 8 hours with frequent interruptions may accomplish meaningfully less deep work than someone with fewer, longer uninterrupted blocks.
