Enter the total number of incidences and the total hours worked (hrs) into the Incidence Density Calculator. The calculator will evaluate and display the Incidence Density.

## Incidence Density Formula

The following formula is used to calculate the Incidence Density.

**ID = I / T**

- Where ID is the Incidence Density (incidences/hr)
- I is the total number of incidences
- T is the total hours worked (hrs)

## How to Calculate Incidence Density?

The following example problems outline how to calculate Incidence Density.

Example Problem #1:

- First, determine the total number of incidences.
- The total number of incidences is given as: 50.

- Next, determine the total hours worked (hrs).
- The total hours worked (hrs) is provided as: 15000.

- Finally, calculate the Incidence Density using the equation above:

ID = I / T

The values given above are inserted into the equation below:

ID = 50 / 15000 = .0033 (incidences/hr)

Example Problem #2:** **

For this problem, the variables needed are provided below:

total number of incidences = 60

total hours worked (hrs) = 10000

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

ID = I / T** = ?**
