First, tell me about your typical workday…
How many hours do you intend to do focused, deep work each day?

How many hours do you intend to do focused, deep work each day?
Context switching is the act of moving your attention from one task, project or tool to another. Each switch carries a hidden cost: time to reload the new context, plus a period of degraded focus while attention residue from the previous task clears.
This calculator turns your own switching habits into an annual figure — hours lost, workdays lost, and a money cost — using recovery costs measured in workplace research rather than generic estimates.
The calculator multiplies your reported app-switch and project-switch frequency by research-based recovery costs, applies a penalty for a large tool stack and for heavy notification volume, then caps the result at 80% of the deep-work hours you said you intend — so the estimate stays realistic — before converting lost hours to money using your hourly value.
Boston Consulting Group and ActivTrak (2023) put the loss at around 40% of productive time, from an average of more than 1,200 app and website switches per day. This calculator produces a personal figure from your own switching frequency and hourly value.
It multiplies your app-switch and project-switch frequency by research-based recovery costs — about 25 minutes to rebuild context after a project switch — applies penalties for a large tool stack and heavy notifications, caps the total at 80% of the deep-work hours you intended, then converts lost hours to money using your hourly value.
Mark, Gudith and Klocke (2008) measured an average of 23 minutes and 15 seconds to fully return to the original task. Shorter self-interruptions cost less, but they still leave attention residue that degrades the next task (Leroy, 2009).
For sustained deep work, roughly two intentional switches an hour is manageable. Digital-worker studies find actual rates far higher — over 1,200 switches a day across apps and sites.
