About this tool
Context Switch Cost Calculator
The Context Switch Cost Calculator computes daily focus time lost, annual productivity cost, and WIP impact from task switch frequency and team size.
• Quantify annual cost of frequent context switching for an engineering health report
• Calculate daily focus time lost to 6 context switches per engineer
• Build case for WIP limits or async-first communication policy
• Model productivity improvement from reducing task switches from 6 to 2 per day

FAQ
What does this tool tell you?
The Context Switch Cost Calculator computes daily focus time lost, annual productivity cost, and WIP impact from task switch frequency and team size.
What affects the result most?
Context switch cost: 23 minutes average to regain focus after an interruption — Gloria Mark, UC Irvine. Types: project switching, interrupt-driven (Slack/email), tool switching, environment switching. WIP limit: working on >2 tasks simultaneously degrades throughput — Little's Law.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
