Pomodoro Planner Calculator
The Pomodoro Technique structures work into focused intervals separated by short breaks, making it one of the most widely used personal productivity systems. This calculator shows exactly how many complete work-and-break cycles fit inside your available time, how many minutes you will spend in focused work, and how many minutes in rest. Enter your total available time, your preferred work-interval length, and your short-break length. The calculator divides your session into complete cycles and reports any leftover time so you can plan even the last few minutes of your day.
Pomodoro cycle formula
Cycle length = work interval + break interval
Complete cycles = floor(total time / cycle length)
Focus time = cycles * work interval
Break time = cycles * break interval
Leftover = total time - (cycles * cycle length)
All times are in minutes. The floor function ensures only complete cycles are counted. Partial cycles are reported as leftover time.
How to use the Pomodoro Planner
- Set your total available time. For a morning work block before meetings, 90 or 120 minutes is typical.
- Choose a work interval that matches your focus capacity. 25 minutes is the classic default; 50 minutes suits deeper tasks.
- Choose a break length. Short breaks of 5-10 minutes allow physical movement and mental rest.
- After every four cycles, take a longer break (15-30 minutes) to restore sustained attention.
- Use the leftover time for low-effort tasks such as email, calendar review, or note organisation.
Pomodoro planner: frequently asked questions
What is the Pomodoro Technique?
The Pomodoro Technique is a time-management method developed by Francesco Cirillo in the late 1980s. You work in focused intervals (classically 25 minutes), then take a short break (classically 5 minutes). After four cycles you take a longer break. The word 'pomodoro' is Italian for tomato, named after the tomato-shaped kitchen timer Cirillo used.
How does this calculator work?
Enter the total time you have available for the task (in minutes), the length of each work interval, and the length of each short break. The calculator divides the total time into complete cycles (work + break) and reports how many full cycles fit, the total focused work time, and the total break time.
What are the classic Pomodoro settings?
The classic settings are 25 minutes of focused work followed by a 5-minute short break, with a 15-20 minute long break after every four cycles. Research on sustained attention suggests intervals of 20-30 minutes balance focus depth with cognitive recovery.
Can I use different interval lengths?
Yes. Some practitioners use 50-minute work intervals with 10-minute breaks (the 52/17 variation). Others use 90-minute sessions aligned with ultradian rhythms. Enter any values you prefer and the calculator will plan the cycles for you.
What happens to leftover time that does not fill a full cycle?
The remaining minutes after the last complete cycle are shown as leftover time. You can use this for a partial work session, review, or transition tasks. The calculator does not count incomplete cycles in the focused work total.
