## DART Rate Formula

The following formula is used to calculate a DART rate:

DR = RIdart *200,000 / EHW

- Where DR is the dart rate
- RIdart is the number of recorded injuries or illnesses that resulted in Days Away, Restricted, or Transferred
- EHW is the total number of employee hours worked.

## DART Rate Definition

**What is a dart rate? **

DART stands for days away, restricted, or transferred. A DART rate is the rate at which injuries occur that result in any one of those in DART.

In other words, the DART incidences per employee hours worked.

## Example Problem

How to calculate DART Rate?

**First, determine the number of injuries that resulted in days away, restricted, or transferred.**For this example problem, the total number of injuries that occurred that resulted in DART was 200.

**Next, determine the number of employee hours worked.**For this example problem, there were a total of 300,000 employee hours worked.

**Finally, calculate the DART rate.**Using the formula above, the dart rate is calculated to be:

DR = RIdart *200,000 / EHW

DR = 200 *200,000 / 300,000

DR = 133.33 injuries per 200,000 hours
