How are breaks counted?

Breaks fall between pomodoros, so a run of N pomodoros has N minus one breaks. Every set number of breaks becomes a long break and the rest are short breaks.

What are the default intervals?

The classic Pomodoro Technique uses 25-minute focus blocks, 5-minute short breaks and a longer 15-minute break after every four pomodoros. You can change all of these.

How is the total time calculated?

Total = (pomodoros × focus length) + (short breaks × short length) + (long breaks × long length). Focus time and break time are also shown separately.

Why are there only N − 1 breaks for N pomodoros?

Breaks sit in the gaps between pomodoros, and there is no break needed after the final one, so a run of N focus blocks has N − 1 breaks in total.

How are long breaks decided?

Every set number of pomodoros (4 by default) ends with a long break instead of a short one. The estimator counts which gaps are long and which are short, then prices each.

Can I model my own routine?

Yes. Change the focus length, short and long break lengths, and how many pomodoros come before each long break, to match any variation of the technique you use.

No. The calculation happens entirely in your browser and no data is sent anywhere.

Pomodoro Estimator — Gera Tools

Pomodoro estimator — plan your real session length

A “pomodoro” is a fixed block of focused work — classically 25 minutes — followed by a short break, with a longer break after every fourth one. Because of those breaks, eight pomodoros take far longer than 8 × 25 minutes on the clock. This estimator adds up your focus time and all the short and long breaks so you can block out a realistic amount of time.

How it works

The tool counts the gaps between pomodoros and decides which are long versus short breaks, then totals the minutes:

gaps        = pomodoros − 1
long breaks = every (cycle)-th gap   (cycle = 4 by default)
short breaks = the remaining gaps
total = pomodoros × focus
      + short breaks × short length
      + long breaks × long length

Example

8 pomodoros, focus 25 min, short break 5 min, long break 15 min, long break every 4:

Focus: 8 × 25 = 200 min
Gaps: 7 → the 4th gap is a long break, the other 6 are short
Breaks: 6 × 5 + 1 × 15 = 30 + 15 = 45 min
Total: 200 + 45 = 245 min ≈ 4h 5m

Pomodoros	Focus	Breaks	Total
4	100 m	15 m	1h 55m
8	200 m	45 m	4h 5m
12	300 m	75 m	6h 15m
