Enter the number of slides and the total presentation time (min) into the Calculator. The calculator will evaluate the Slides Per Minute. 

Slides Per Minute Formula

SLPM = S / T


  • SLPM is the Slides Per Minute (slides/min)
  • S is the number of slides
  • T is the total presentation time (min)

To calculate Slides Per Minute, divide the number of slides by the total presentation time.

How to Calculate Slides Per Minute?

The following steps outline how to calculate the Slides Per Minute.

  • First, determine the number of slides. 
  • Next, determine the total presentation time (min). 
  • Next, gather the formula from above = SLPM = S / T.
  • Finally, calculate the Slides Per Minute.
  • After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

number of slides = 59

total presentation time (min) = 20
