How to Use This Tool
Convert daily context switches and recovery time into weekly capacity cost. Calculate weekly hours and labor value lost to context switching using switch count, refocus minutes and workdays.
The decision this tool supports
Brief interruptions look harmless individually but their repeated recovery time can consume a material share of weekly capacity. This page keeps the decision bounded to weekly fragmentation cost and the supporting outputs shown beside it. Focus Fragmentation Cost does not import an account, infer a market rate, or silently substitute an industry average.
Inputs and units
The Focus Fragmentation Cost calculation uses Context switches per day, Average refocus time, Workdays per week, Loaded hourly value, Recoverable share. Keep all money values in one currency and all time, distance, mass, energy or volume entries in the unit printed beside the field. Mixing Focus Fragmentation Cost scopes can produce a plausible number with the wrong meaning.
- Context switches per day is entered in switches.
- Average refocus time is entered in minutes.
- Workdays per week is entered in days.
- Loaded hourly value is entered in currency/hour.
- Recoverable share is entered in %.
Formula and worked check
Weekly fragmented hours = switches per day × refocus minutes × workdays ÷ 60; cost multiplies by loaded hourly value. Eighteen switches daily at six minutes over five days fragment nine hours weekly, valued at $495 with 3.6 hours modeled recoverable. The Focus Fragmentation Cost default is an executable known-answer case, not a benchmark or recommendation. Change one input and verify that the direction of weekly fragmentation cost still matches the stated relationship.
How to interpret the result
Recoverable time is a scenario, not a guarantee; use observation rather than memory to set switch count and refocus time. The additional Focus Fragmentation Cost outputs expose the denominator, comparison, capacity or reverse value needed to audit the primary result instead of presenting one unexplained number.
Assumptions
- Switches are counted only when refocus time is incurred.
- Recovery intervals do not overlap.
- Loaded hourly value is a planning value, not necessarily wages.
Save the Focus Fragmentation Cost input values and date with any material decision. A later Focus Fragmentation Cost rerun is reproducible only when the same assumptions and units are available.
Limitations and safety boundary
It does not value creative quality, fatigue or collaboration benefits and assumes each switch has the same nonoverlapping recovery time. Focus Fragmentation Cost is an estimate and cannot replace a contract, local code, licensed professional, calibrated measurement, lender statement or platform report where one governs the decision.
