1. What is OSHA Average Employee Calculation?

The OSHA (Occupational Safety and Health Administration) average number of employees is calculated by summing the number of employees for each month of the year and dividing by 12. This calculation is important for determining OSHA reporting requirements and injury/illness rates.

2. How Does the Calculator Work?

The calculator uses the OSHA average employee formula:

Where:

• Monthly employees — Number of employees each month
• 12 — Number of months in a year

Explanation: The calculation provides a simple average of workforce size over the entire year.

3. Importance of Average Employee Calculation

Details: OSHA uses this average to determine if your business must keep injury and illness records, and to calculate incident rates. Businesses with 10 or fewer employees may be exempt from certain OSHA recordkeeping requirements.

4. Using the Calculator

Tips: Enter the number of employees for each month. Count all full-time, part-time, temporary, and seasonal workers. Include owners and supervisors if they are on payroll.

5. Frequently Asked Questions (FAQ)

A: Count each part-time employee the same as a full-time employee. OSHA doesn't use full-time equivalents (FTEs) for this calculation.

Q2: What if my business wasn't open all year?
A: For businesses operating less than a full year, still divide by 12 months to get the annual average.

Q3: How does this affect OSHA reporting?
A: Businesses with 11+ employees typically must keep OSHA injury and illness records. Some high-risk industries have different thresholds.

Q4: Should I include temporary workers?
A: Yes, include all workers on your payroll, including temporary and seasonal workers.

Q5: When is this calculation used?
A: Primarily for OSHA Form 300A (Summary of Work-Related Injuries and Illnesses) and for calculating incident rates.
