Time audits, meeting costs, focus plans, energy scheduling — type your problem and get a straight, no-hype answer in seconds. The full detailed report costs less than a cup of coffee: $2.95.

Meetings, email and small admin tasks claim more of a working week than most people admit, and what remains is not all deep work — transitions and quick tasks quietly take about a fifth of it. This calculator subtracts the shallow load from your real weekly hours, applies that honest overhead, and caps the result at the researched daily ceiling of roughly 3-4 hours of true focused cognition. The number it returns is your realistic deep-work capacity, and the verdict tells you whether your week is protecting it, wasting it, or simply built without room for it.
Work out how many genuinely focused hours your week actually leaves after meetings, email and admin — and see whether the leftover matches the researched 3-4 hour daily ceiling for deep work.
Research on focused cognitive work consistently finds quality drops after roughly 3-4 hours of intense concentration a day. Adding more hours to the calendar does not add real thinking time — it just stretches tired attention.
For most roles, no: email is reactive triage that fragments attention rather than sustaining it. That is not a criticism of the work — it simply belongs in a different bucket, and the calculator treats it that way so the focus number is honest.
Then the problem is structural, not personal — the shallow load is eating the week. The fix is cutting or consolidating one meeting block and one admin habit, not working longer hours.
Every tool answers instantly from our own knowledge and calculators — no AI wait, no account. Rest is productive: these tools free your time, they do not fill it. Want the deeper, personalised version? Each has a $2.95 full report.
