# What is the calculation to find the total break time and work time using the Pomodoro technique?

I am testing pomodoro efficiency and would like to learn the proper equation for finding total break and work time in a set duration of hours.

My sample is: If I work 90 minutes, break for 15 minutes, inside of a 9.5 hour time, how can I figure out how many 15 minute breaks are available to tally the total break time to subtract it from the total work time?

No fancy calculations needed. Just find the total number of minutes in a workday and divide by 105 (90+15). The integer portion will be the number of breaks you can take in a day. $That$ times 15 is the total break time in a day.
• $9.5*60=570$ minutes in a 9.5 hour work day. $90+15=105$ minutes in a work/break cycle. Using the floor function $Int(570/105) = 5$ $whole$ work/break cycles in 9.5 hours. $5*15=75$ is the total break time in a 9.5 hour day. – poetasis Sep 7 '18 at 15:31
