DART Rate Calculator
Calculate Days Away, Restricted, or Transferred rate for workplace safety analysis
Calculate DART Rate
OSHA typically requires annual reporting. Other periods will be annualized for comparison.
Days Away, Restricted, or Transferred cases during the period
All employee hours worked (excluding vacation, sick leave, holidays)
Alternative: Calculate from Employee Data

Calculation Details
Formula: DART Rate = (Total DARTs × 200,000) ÷ Total Hours Worked
Calculation: (0 × 200,000) ÷ 0 = 0.00
200,000 factor: Represents 100 employees working 40 hours/week for 50 weeks
Example Calculation
Manufacturing Company Example
Company: 100 employees working 40 hours/week for 50 weeks
Total Hours Worked: 100 × 40 × 50 = 200,000 hours/year
DART Incidents: 5 incidents during the year
DART Rate Calculation
1. Apply OSHA formula: DART Rate = (Total DARTs × 200,000) ÷ Total Hours
2. Calculate: (5 × 200,000) ÷ 200,000 = 5.00
Result: DART Rate = 5.00 (High Risk)
Interpretation: This rate exceeds 4.125, indicating high workplace safety concerns requiring immediate attention.

Understanding DART Rate
What is DART Rate?
DART stands for "Days Away, Restricted, or Transferred." It's a workplace safety metric developed by OSHA (Occupational Safety and Health Administration) to measure the frequency of workplace injuries and illnesses that result in days away from work, restricted work activity, or job transfer.
Why is DART Rate Important?
- •OSHA compliance and regulatory requirements
- •Workplace safety performance measurement
- •Risk assessment and insurance considerations
- •Benchmarking against industry standards
DART Rate Formula
DART Rate = (Total DARTs × 200,000) ÷ Total Hours Worked
- Total DARTs: Number of incidents resulting in days away, restricted work, or job transfer
- 200,000: Standard OSHA factor (100 employees × 40 hours/week × 50 weeks)
- Total Hours: All employee work hours during the reporting period
What Counts as DART?
- • Days away from work due to injury/illness
- • Restricted work activity or limited duties
- • Job transfer to avoid aggravating injury
- • Medical treatment beyond first aid
OSHA Reporting Requirements
When to Report
- • Work-related injuries requiring medical treatment
- • Illnesses caused by workplace exposure
- • Fatalities (within 8 hours)
- • Hospitalizations (within 24 hours)
Record Keeping
- • OSHA Form 300 (Log of Work-Related Injuries)
- • OSHA Form 301 (Incident Report)
- • OSHA Form 300A (Annual Summary)
- • Maintain records for 5 years
