Work out your numbers
Small tools for the questions that come up around focused work: how many blocks fit, how long they should be, how long to rest, and what interruptions and meetings really cost.
How many Pomodoros fit into your workday?
A full 8-hour day holds 15 Pomodoros — 6 h 15 min of real focus. Calculate the number for your own hours, interval length and break length.
Open25/5, 52/17 or 90/20 — which focus interval fits you?
Compare the three best-known focus intervals — 25/5, 52/17 and 90/20 — and find the one that matches how you actually work.
OpenHow long should your break be?
A 25-minute block earns a 5-minute break, 50 minutes earns 10, 90 minutes earns 20. Calculate the break for your own focus block.
OpenWhat do interruptions really cost you?
Eight interruptions a day can cost about 1.5 hours of focus — around 46 workdays a year. Calculate your own number from interruptions, handling time and refocus time.
OpenHow much deep work can you realistically do?
Most people manage 1 to 4 hours of real deep work a day. Answer two questions to get a realistic range for your experience and schedule, plus a weekly target.
OpenHow many focus blocks survive your meetings?
Four 30-minute meetings spread across a day leave room for zero 90-minute focus blocks. Clustered together, the same meetings leave three. Calculate your own day.
