- Pomodoros = task time ÷ pomodoro length, rounded up.
- A short break follows each pomodoro except the last, and a long break follows every fourth one.
- The result shows focus time, break time, total time and the finish time from your start time.
- Change the lengths in the advanced options to use 50/10 or any other rhythm.
How to use the pomodoro calculator
Choose what you know
Pick How long the task takes, or How many pomodoros if you already have a number.
Enter the task and start time
Add hours and minutes, then the time you plan to start.
Adjust the rhythm
The default is 25 minutes of focus, 5 minutes of short break and a 15 minute long break after four rounds.
Read the plan
See the pomodoro count, the total time and a schedule of each session with its start and end time.
How pomodoros are calculated
A pomodoro is one block of focused work. The calculator divides your task time by the block length and rounds up, so a partly used last block still counts as a full one. It then adds the breaks between blocks to find the finish time.
Pomodoro formulas
Pomodoros = task minutes ÷ pomodoro length, rounded up
Breaks = pomodoros − 1 breaks, with a long break after every 4th pomodoro
Total time = pomodoros × length + all break minutes
The last pomodoro has no break after it.
Pomodoro examples
Example 1: a 3 hour task starting at 9:00 AM
25 minute pomodoros, 5 minute short breaks and a 15 minute long break.
- Pomodoros 8
- Focus time 3 h 20 min
- Break time 45 min (6 short, 1 long)
- Total time 4 h 5 min
- Finish time 1:05 PM
Eight rounds of 25 minutes give 3 h 20 min of focus, a little more than the 3 hours planned.
Example 2: four pomodoros
Starting at 9:00 AM.
- Focus time 1 h 40 min
- Break time 15 min (3 short breaks)
- Finish time 10:55 AM
The long break only appears after the fourth pomodoro, and there is none after the last one.
Example 3: a late start
A 3 hour task starting at 11:00 PM.
- Pomodoros 8
- Finish time 3:05 AM (+1 day)
The result shows the next day when the plan runs past midnight.
Total time for common pomodoro counts
Using 25 / 5 / 15 minutes.
- 1 pomodoro 25 min
- 2 pomodoros 55 min
- 4 pomodoros 1 h 55 min
- 6 pomodoros 3 h 5 min
- 8 pomodoros 4 h 5 min
- 12 pomodoros 6 h 15 min
Total time includes the short and long breaks between pomodoros.
Where a pomodoro calculator helps
Study planning
Split a revision session into blocks and know when you will finish.
Work and deep focus
Estimate how many focus blocks a project needs.
Time boxing
Set a fixed number of pomodoros per task and stop on time.
Team sprints
Plan a shared focus hour with a set end time.
The 25/5 rhythm is a starting point. Many people prefer 50 minutes of focus and a 10 minute break. Related tools: Time Duration Calculator and Tenth of an Hour Calculator.
Pomodoro calculator FAQ
How long is a pomodoro?
The classic pomodoro is 25 minutes of focused work followed by a 5 minute break. Many people use other lengths, which you can set in the advanced options.
How many pomodoros fit in 2 hours?
With 5 minute short breaks, 4 pomodoros take 1 h 55 min, so 4 fit into 2 hours.
How many pomodoros are in an 8 hour day?
Including breaks, about 15 pomodoros fit into 8 hours, but most people do far fewer deep-work blocks in a day.
When do you take the long break?
Traditionally after every fourth pomodoro. You can change this in the advanced options.
Why is the last pomodoro rounded up?
If the task needs 3 hours, seven pomodoros give 2 h 55 min of focus, so an eighth is needed for the last 5 minutes. Use the schedule to stop early if you want.
Can I plan past midnight?
Yes. If the finish time falls on the next day, the result shows +1 day.
