Attrition - Attrition Rate

What is Attrition Percentage. If Opening head count is 100 and attrition percentage is 5% then is it mean that, 5 employees left the job?
Attrition rate= No. of Employees resigned / (No. of employees in an org. + no. of emplyees joined - no. of employees resigned)*100.
Is this formula is rite? kindly some one clarify my doubt pls. its very urgent

Dear Santosh
The attrition percentage can be calculated by considering the average number of employees leaving the organisation month on month with the average employee strength for the same period. For example
April - Employee strength is 100 and 5 employees leave the % is 5.
May - Employee strength is 106. Average strength is (100+106)/2 = 103 and employee leaving is 3. Average attrition is (5+3)/ 2 = 4. Atrrition rate is 4/103 = 3.8%.
Likewise calculate this month on month to arrive at the attrition rate.

Yes, your understanding of the attrition percentage formula is correct. Attrition percentage, also known as employee turnover rate, is a measure of the rate at which employees leave an organization.

The formula you provided is the correct way to calculate the attrition percentage:
Attrition percentage = (No. of Employees resigned / (No. of employees in an org. + no. of employees joined - no. of employees resigned)) * 100

So, in your example, if the opening headcount is 100 and the attrition percentage is 5%, then it means that 5 employees have left the job during the given time period.

I hope this clarifies your doubt. Let me know if you have any further questions!
