Study Session Pomodoro Timer Calculator

Plan your study sessions using the Pomodoro Technique. Enter your available study time and preferences to calculate how many Pomodoro cycles you can complete, along with total focus and break time.

Formula

Time for one complete set (N Pomodoros):
Tset = N × F + (N − 1) × S + L

Where:
N = Pomodoros per set
F = Focus duration per Pomodoro (minutes)
S = Short break duration (minutes)
L = Long break duration (minutes)

Greedy fitting algorithm: Pomodoros are added one at a time. After each Pomodoro, a short break is added (if it completes a set, a long break is added instead), but only if the remaining time can accommodate the break plus at least one more focus period. The last Pomodoro of the session carries no trailing break.

Unused time:
Tunused = Ttotal − (Tfocus + Tshort breaks + Tlong breaks)
