Free pomodoro session calculator

Plan a focus session in minutes: enter the time you have, set your work block and short break, and see how many whole pomodoros fit and how much focused work that adds up to — using the classic 25-minute Pomodoro Technique with a long break after every fourth sprint. Every number is updated live, as you type.

Overview

What the Pomodoro session planner does

This Pomodoro session planner turns a block of available time into a count of focus sessions — "pomodoros" — and the total minutes of focused work you can fit inside it. Type how many minutes you have, set your work block and short break, and it reports how many full pomodoros fit and how much of that time is real focused work.

A pomodoro is one fixed-length sprint of concentrated work followed by a short rest. The classic length is 25 minutes of work and a 5-minute break, with a longer break after every fourth pomodoro. The planner uses those defaults, counts only the whole pomodoros that fit your time budget, and ignores any partial sprint at the end — because a half-finished pomodoro is not a pomodoro.

One fixed sprint of focused work — classically 25 minutes — named after the tomato-shaped kitchen timer Francesco Cirillo used. Plural: pomodori.
A brief rest, classically 5 minutes, taken after each pomodoro to recover before the next sprint.
A longer rest of 15–30 minutes taken after every fourth pomodoro. This planner uses 15 minutes.
A run of four pomodoros plus their breaks, ending in a long break. The planner counts each completed pomodoro as one cycle.
The method

The Pomodoro Technique, explained

The Pomodoro Technique is a time-management method developed by Francesco Cirillo in the late 1980s, while he was a university student looking for a way to focus. He committed to just ten minutes of study, timed with a tomato-shaped (pomodoro, in Italian) kitchen timer — and the timer gave the method its name.

The core idea is that a short, hard time limit makes focus easier: you are not promising to work all afternoon, only until the timer rings. Each unbroken sprint is one pomodoro. After it, you rest briefly, then start the next. The breaks are not optional padding — they are what makes repeated deep focus sustainable across a long day.

  1. Choose a task to work on.
  2. Set a timer for 25 minutes and work on the task with no interruptions until it rings.
  3. Take a 5-minute short break when the timer rings — step away, stretch, look out a window.
  4. Repeat until you have completed four pomodoros.
  5. Take a longer break of 15–30 minutes after the fourth pomodoro, then start the cycle again.
If a distraction breaks your concentration mid-pomodoro, the technique says to note it, set it aside, and either finish the pomodoro or abandon it and start fresh. A pomodoro is indivisible — there is no "half a pomodoro" — which is exactly why this planner counts only whole sprints.
The maths

How the planner works out how many pomodoros fit

The planner steps through your available time one pomodoro at a time. Each sprint costs its work block plus the break that follows it — a short 5-minute break for sprints 1–3, and a 15-minute long break after the 4th. A pomodoro counts as long as its work block still fits in the time you have left; the trailing break may run a little past the end of your window.

short cycle = work + short break = 25 + 5 = 30 min
long cycle = work + long break (every 4th) = 25 + 15 = 40 min
count a pomodoro while: remaining time ≥ work block
focused work = pomodoros × work block

The two numbers the planner reports are cycles (whole pomodoros completed) and minutes of focused work (cycles × your work block). Anything left over that is shorter than one work block is dropped, because you cannot complete a pomodoro in it.

Worked example

A worked example: a two-hour study block

Example: 120 minutes, 25-minute work, 5-minute break

Sam has a 120-minute evening study block and uses the classic settings — a 25-minute work block and a 5-minute short break. Here is exactly how the planner counts the pomodoros.

Step 1 — Pomodoros 1 to 3 (short breaks)

Each of the first three pomodoros costs 25 + 5 = 30 minutes. Three of them use 90 minutes and leave 30 minutes on the clock (120 − 90 = 30).

Step 2 — Pomodoro 4 (the long-break sprint)

30 minutes remain, which is more than one 25-minute work block, so the 4th pomodoro counts. The 4th sprint triggers the 15-minute long break, so its full cycle is 25 + 15 = 40 minutes — that long break runs a little past the two-hour mark, but the work block itself fit, so the pomodoro is complete.

Step 3 — Read the result

After the 4th pomodoro fewer than 25 minutes remain, so no 5th sprint can start. The planner reports 4 cycles and 100 minutes of focused work (4 × 25).

4 cycles — 100 minutes of focused work
In a 120-minute block at 25-min work / 5-min break you complete 4 pomodoros and 100 minutes of focused work (4 × 25). Three short breaks plus the work fills 115 minutes; the long break after the 4th pomodoro extends a little past the two-hour window.
Reference

How many pomodoros fit in common time blocks

At the classic settings — a 25-minute work block, a 5-minute short break, and a 15-minute long break after every fourth pomodoro — here is how many whole pomodoros fit common stretches of time, and the focused-work minutes that go with them. These are the planner's own outputs.

Available timePomodorosFocused work (min)
25 min125
60 min (1 hr)250
90 min375
120 min (2 hr)4100
180 min (3 hr)5125
240 min (4 hr)7175

Computed at 25-min work / 5-min short break / 15-min long break after every 4th pomodoro. Counts rise unevenly because the long break makes every fourth sprint cost more time; change the work block or break in the planner and these numbers shift.

Planning

How many pomodoros should you plan in a day?

Focused work is not the same as time at a desk. Most people sustain roughly 8 to 12 quality pomodoros a day — about 3.5 to 5 hours of genuinely focused work — with the rest of the day spent on breaks, meetings, email, and lower-intensity tasks. Plan the day in pomodoros, not in raw hours, and you build the recovery breaks in from the start.

  • Protect the breaks. Skipping the rest to "get more done" is the fastest way to burn out and lose the next pomodoro's focus.
  • Group similar work into back-to-back pomodoros so you are not paying a context-switch cost on every sprint.
  • Adjust the block length to the task. The planner lets you change the work block — some people prefer shorter 15-minute sprints for dread tasks, or longer 50-minute blocks for deep flow.
  • Count, don't guess. Use the planner to set a realistic target for a session, then stop when you hit it.
The planner uses a fixed 15-minute long break after every fourth pomodoro. Cirillo's method allows anywhere from 15 to 30 minutes for that long break — take the longer rest if you have a full day of focus ahead.
Quick answers

Common Pomodoro questions

How long is one pomodoro?

Classically 25 minutes of focused work followed by a 5-minute short break. This planner uses 25 and 5 by default, but you can set the work block and break to whatever lengths suit your task.

When do I take the long break?

After every fourth pomodoro. The classic long break is 15 to 30 minutes; this planner assumes 15 minutes when it works out how many sprints fit your time.

Why does the planner ignore the leftover time at the end?

A pomodoro is indivisible — it only counts if a full work block fits. If fewer minutes remain than one work block (under 25 minutes by default), no further pomodoro can start, so the planner stops counting there.

Methodology

How this planner works and sources

This planner applies the classic Pomodoro Technique structure exactly: a 25-minute work block (adjustable), a 5-minute short break (adjustable), and a fixed 15-minute long break after every fourth pomodoro. It steps through your available time, counting each pomodoro whose work block fits, and reports the whole pomodoros completed and the focused-work minutes that go with them. The maths runs entirely in your browser — nothing is sent anywhere.

Four. At the classic 25-minute work block with a 5-minute short break, a 120-minute block completes 4 pomodoros and 100 minutes of focused work (4 × 25). The long break after the 4th pomodoro runs a little past the two-hour mark.

Most people sustain about 8 to 12 quality pomodoros a day — roughly 3.5 to 5 hours of genuinely focused work — with the rest of the day for breaks, meetings, and lighter tasks. Plan in pomodoros, not raw hours, so the recovery breaks are built in.
