Enter the total number of occurrences and the total number of events into the Calculator. The calculator will evaluate the Event Rate. 

Event Rate Formula

ER = OC / E

Variables:

  • ER is the Event Rate (occurrences/events)
  • OC is the total number of occurrences
  • E is the total number of events

To calculate the Event Rate, divide the number of occurrences by the number of events.

How to Calculate Event Rate?

The following steps outline how to calculate the Event Rate.

  • First, determine the total number of occurrences. 
  • Next, determine the total number of events. 
  • Next, gather the formula from above = ER = OC / E.
  • Finally, calculate the Event Rate.
  • 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 occurrences = 48

total number of events = 93
