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
