Number of focused work blocks that fit in your session
How does this calculator work?
The Pomodoro Technique splits work into focused blocks separated by breaks. This calculator counts how many blocks fit in your session time, accounting for short breaks between blocks and a longer break after every N blocks. Change the default 25/5/15/4 setup to your preferred rhythm. Focus efficiency = work time ÷ elapsed time.
Formula
How this is calculated
The Pomodoro Technique divides work into focused intervals (typically 25 minutes) separated by short breaks (5 minutes), with a longer break after every N intervals (usually 4). This calculator lets you customise all four parameters and then counts how many complete work blocks — each followed by the appropriate break — fit inside your available session time.
The algorithm steps through each work block in order. Every C-th block (where C is your "cycles per set") triggers a long break instead of a short break. Counting stops when the next work block plus its preceding break would overflow the session time.
Focus efficiency is the percentage of elapsed time actually spent working (ignoring breaks). A standard 4 × 25 min + 3 × 5 min + 15 min session achieves about 68% efficiency. Longer work blocks or shorter breaks increase efficiency; more or longer breaks reduce it.
Frequently asked questions
The original technique by Francesco Cirillo uses 25-minute work blocks, 5-minute short breaks, a 15-minute long break after every 4 blocks. One full set takes 2 hours and contains 100 minutes of focused work.
Yes — many practitioners use 50/10 or 90/20 patterns. Adjust the work and break fields to match your preferred rhythm. Research suggests most people can sustain deep focus for 45–90 minutes before needing a meaningful break.
After all complete sets of C pomodoros, there may still be time for some additional blocks before the session ends — but not enough for a full set. "Extra pomodoros" counts those partial-set blocks.
