Two hours at 25 / 5
Four 25-minute sessions plus three five-minute breaks use 115 of your 120 minutes. That leaves five minutes for setting up or writing a next-step note. A break after the fourth session is outside this calculation.

Count focus time and breaks together
Dividing two hours by 25 minutes misses the breaks between sessions. This calculator treats your time as one window: complete focus sessions, a short break between each pair, and any minutes left over. It does not add a break after the final session or insert longer breaks automatically.
With 120 available minutes, 25-minute focus sessions, and five-minute breaks, you can fit four sessions. That is 100 minutes of focus plus three breaks totaling 15 minutes: 115 minutes in all, with five minutes left over. A fifth full session would not fit in the same window.
The calculation is floor((available minutes + break minutes) / (focus minutes + break minutes)). This counts only complete sessions and includes breaks between them. If you have less time than one focus session, the result has no sessions. Choose a shorter session or a larger time window before starting.
Calculate a study window
- Enter the total minutes available, including short breaks.
- Choose the length of a focus session and the break between sessions.
- Calculate the plan and check the focus, break, and remaining time.
- Choose Prepare next session, then Start focus. Between sessions, prepare and start the planned break when you are ready.
Three practical time-budget examples
One hour at 25 / 5
Two focus sessions use 50 minutes and the one break between them uses five. The schedule takes 55 minutes, leaving five minutes free. A third session would need 85 minutes in total.
Two hours at 50 / 10
Two 50-minute sessions with one ten-minute break use 110 minutes. The remaining ten minutes are spare time. Choose the interval that fits your task and adjust the settings before generating the schedule.
Read the result as a time budget
- Focus time
- The number of complete sessions multiplied by the focus duration. This is the planned time on the task, not a prediction of how much work you will finish.
- Break time
- One short break between consecutive sessions. There are three breaks for four sessions, and no break is needed for a single session.
- Time left
- The minutes remaining after the planned sessions and breaks. Keep them free or adjust the interval; the calculator does not turn them into a partial focus session.
Questions about the pomodoro calculator
How many Pomodoros fit in two hours?
With 25 minutes of focus and five-minute breaks, four complete Pomodoros fit in two hours. Four sessions take 100 minutes and the three breaks between them take 15 minutes, leaving five of the 120 minutes unused.
Does the calculator include a break after the last session?
No. It counts breaks only between focus sessions. If you want a final break inside the same time window, subtract that break from your available minutes before calculating.
Does the calculator add a long break after four Pomodoros?
No. It uses the same short-break length between all sessions. Reserve longer breaks outside the time you enter, or calculate separate study windows on either side of a longer break.
Can I calculate sessions longer or shorter than 25 minutes?
Yes. Change the focus and break durations before calculating. For example, two 50-minute sessions and one ten-minute break take 110 minutes. The calculator uses the durations you enter rather than requiring a fixed 25/5 rhythm.
Why does the result have time left over?
Only complete focus sessions fit into the schedule. If the remaining minutes are not enough for the next break and focus session, they stay unused. You can keep that margin for setup or choose a shorter focus duration.
Can I start a timer from the calculated schedule?
Yes. Choose Prepare next session or the play control beside a session, then press Start focus. Completing the countdown checks off that session. Leaving the page resets its timer. You can also mark sessions complete manually, print the plan, or export it as CSV. The plan saves automatically when browser storage is available; it does not sync with account session history.
