Calculate events per second from an event count and elapsed time, or find the event count or duration from a rate, with per-minute and per-hour rates.

Events Per Second Formula

The following two example problems outline the steps and information needed to calculate the Events Per Second.

EPS = E / T / 60

Variables:

  • EPS is the Events Per Second (events/s)
  • E is the total number of events 
  • T is the total amount of time (min) 

To calculate events per second, divide the event count by elapsed time in seconds. If time T is entered in minutes, EPS = E/(60T). The result is a window average; it does not describe traffic peaks or individual event timing.

How to Calculate Events Per Second?

The following steps outline how to calculate the Events Per Second.

  1. First, determine the total number of events. 
  2. Next, determine the total amount of time (min). 
  3. Next, gather the formula from above = EPS = #E / T /60.
  4. Finally, calculate the Events Per Second.
  5. 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.

total number of events = 500

total amount of time (min) = 5

EPS =500/(5 ×60) ≈1.666667 events/s. A rate-based projected count may be fractional as an expectation; an observed or target event count is a whole number.
