Accident Frequency Rate Calculator
Accident frequency rate (AFR) is a vital metric used by organizations to measure workplace safety. It represents the number of accidents per 200,000 hours worked, helping businesses identify trends and implement safety measures.
Formula
The formula for accident frequency rate is:
AF = A × 200,000 / HW
Where:
- AF = Accident Frequency Rate
- A = Number of Accidents
- HW = Total Hours Worked
How to Use
- Record the number of workplace accidents (A) within a given period.
- Note the total number of hours worked (HW) during the same period.
- Enter these values into the calculator.
- Click “Calculate” to find the accident frequency rate.
Example
Suppose a company had 5 accidents (A) over a period where 1,000,000 hours (HW) were worked.
Using the formula:
AF = (5 × 200,000) / 1,000,000 = 1
This means the accident frequency rate is 1.
FAQs
- What is an accident frequency rate?
It is a metric that measures the number of workplace accidents relative to hours worked. - Why is accident frequency rate important?
It helps organizations monitor safety performance and implement preventive measures. - What is the significance of 200,000 hours in the formula?

Typically, reportable incidents or accidents resulting in injury are included. - Can AFR be used to compare companies?
Yes, but only within the same industry due to differing operational risks. - What is a good accident frequency rate?
A lower AFR indicates better workplace safety, but acceptable rates vary by industry. - How often should AFR be calculated?
Monthly, quarterly, or annually, depending on organizational needs. - Can AFR be zero?
Yes, a zero AFR indicates no workplace accidents occurred during the period. - How can a company lower its AFR?
By improving training, enforcing safety protocols, and conducting regular safety audits. - Does AFR consider near-misses?
No, AFR typically accounts for actual reportable accidents. - Is AFR used internationally?
Yes, AFR is a standard metric in many countries for evaluating workplace safety. - What is the difference between AFR and severity rate?
AFR measures frequency, while severity rate measures the impact of accidents. - Does AFR vary across industries?
Yes, industries like construction or manufacturing often have higher AFRs compared to office environments. - Are temporary workers included in AFR calculations?
Yes, hours worked by all employees, including temporary staff, are included. - What is the role of AFR in safety programs?
AFR serves as a key performance indicator to evaluate the effectiveness of safety measures. - Can AFR be used for insurance purposes?
