In today’s competitive and safety-conscious work environment, monitoring and improving employee safety is crucial for any organization. Among the various safety metrics used by employers, the DART Rate (Days Away, Restricted, or Transferred rate) stands out as a key indicator of workplace safety performance. It helps track serious work-related injuries and illnesses that result in lost or restricted work time. To make this calculation easier and more accessible, our DART Rate Calculator provides an accurate and simple way to determine your company’s DART rate instantly.
✅ What is the DART Rate?
The DART Rate is a metric used by the Occupational Safety and Health Administration (OSHA) to measure workplace incidents that result in Days Away from work, Restricted duties, or Transfers to another job. It essentially quantifies the number of such incidents per 100 full-time employees over a standard period, typically a year.
A lower DART Rate indicates a safer workplace, while a higher rate may suggest that improvements are needed in safety protocols or hazard control.
✅ DART Rate Formula
To calculate the DART Rate, the following formula is used:
DART Rate = (Number of DART incidents × 200,000) ÷ Total number of hours worked by all employees
- Number of DART incidents: This includes all cases that involve days away from work, restricted duty, or job transfer.
- 200,000: This is the base number representing 100 full-time employees working 40 hours a week for 50 weeks a year.
- Total number of hours worked: This includes all hours worked by all employees during the year.
✅ How to Use the DART Rate Calculator
Using our online DART Rate Calculator is straightforward. Here’s a step-by-step guide:
- Enter the Number of DART Incidents
This refers to the number of recordable injuries or illnesses that resulted in days away, restricted work, or job transfers. - Enter the Total Number of Hours Worked by All Employees
Make sure to include hours worked across all departments and job types for the entire period. - Click the “Calculate” Button
The tool instantly computes your DART Rate using the entered values and displays the result below the button.
Example
Suppose your company had:
- 5 DART incidents in a year
- A total of 500,000 employee hours worked
Using the formula:
DART Rate = (5 × 200,000) ÷ 500,000
DART Rate = 1,000,000 ÷ 500,000
DART Rate = 2.00
So, your company’s DART Rate is 2.00.
✅ Why is the DART Rate Important?
- Regulatory Compliance
OSHA uses DART rates to identify high-risk workplaces. A high rate might trigger inspections or audits. - Benchmarking
Companies use DART rates to compare their safety performance with others in the industry. - Insurance and Liability
Lower DART rates can lead to reduced insurance premiums and fewer liability concerns. - Internal Improvement
It helps in identifying unsafe practices or departments that need targeted interventions.
✅ Best Practices to Reduce DART Rate
- Conduct regular safety audits and inspections.
- Train employees on safety protocols and equipment use.
- Encourage reporting of near misses.
- Address workplace hazards promptly.
- Provide proper PPE (Personal Protective Equipment).
- Maintain clear safety policies and procedures.

✅ Frequently Asked Questions (FAQs)
1. What does DART stand for?
DART stands for Days Away, Restricted, or Transferred, representing cases that result in lost time, restricted work, or job reassignment.
2. What is a good DART rate?
A good DART Rate depends on your industry. Generally, the lower the rate, the better. A rate below the industry average is considered good.
3. Who reports the DART rate?
Employers must report DART incidents and calculate the DART rate annually for OSHA compliance and internal safety audits.
4. Why is 200,000 used in the formula?
200,000 represents the standard work hours for 100 full-time employees working 40 hours/week for 50 weeks/year.
5. Is the DART rate mandatory to calculate?
It’s not mandatory for all businesses, but it’s essential for OSHA recordkeeping and safety program evaluations.
6. What types of incidents are included in DART?
Only incidents that result in days away from work, restricted duties, or transfers to another job.
7. How often should DART rate be calculated?
Most companies calculate it annually, but it can also be done quarterly or monthly for close monitoring.
8. Is a high DART rate bad?
Yes, a high DART Rate indicates a high frequency of serious injuries, which may lead to compliance issues and higher costs.
9. How can I reduce my DART rate?
Focus on proactive safety training, incident reporting, and workplace hazard mitigation.
10. Is this calculator OSHA approved?
While the calculator uses the OSHA formula, it’s a third-party tool and not officially certified by OSHA.

No, the calculator only computes and displays the DART rate. It does not collect or store user data.
13. What’s the difference between DART Rate and TRIR?
TRIR includes all recordable incidents, while DART only includes the more severe ones (involving time away or restriction).
14. Can I calculate DART for individual departments?
Yes. Just input the department’s DART incidents and total worked hours.
