Hello All
I need your help for calculating Attrition Rate.I myself tried this using Attrition Rate formula i.e,
Attrition Rate=Total Headcounts left in a period/(Total headcount at the start of the period+Total headcounts recruited in the period)*100
and herewith attaching file. I would like to know whether I am following right track for the same?If yes,then please guide me how to calculate Average attrition rate as given in the sheet.
anticipating your response.

You are really smart. Attrition Formula mentioned by you and also used in excel sheet is absolutely correct.

Hi,
I would suggest that you first decide what is the period for which you want to report attrition. Ideally it should be reported on quarterly basis and then aggregated for a year.
There are two ways to calculate quarterly attrition
Option1 - Simple
x = no of employees in the beginning of quarter
y = no of employees who left the company in the quarter
attrition = (y / x)*100
Option 2 - Complex
x = no of employees in the beginning of quarter
y = no of employees who left the company in the quarter
z = no of new employees who joined the company in the quarter
attrition = [y / (2x+z)/2]*100
Option 1 gives a higher figure so smart HR people use option 2.

  • I had a second look at your excel sheet and noticed one anomaly.
  • In case of excel example given by you, Total head count at the start of the period for 2nd and 3rd quarter needs to be changed. It will be the closing balance of the earlier quarter. Accordingly I have changed the figures in attached file.
  • I am not sure taking average of attrition rate of three quarters will give us average attrition rate for the period July '10 to March '11.
  • I have calculated Attrition Rate using same formula for the period July '10 to March '11, which works out to be 15.12%.
  • I am not very sure why there is such a big variation between quarterly attrition rate and combined attrition rate of 3 quarters.
  • Experts please give your views. Correct me if I am wrong. Here I feel we need Mathematics Experts to respond and not HR experts.

Dear Athirumaran,
Lets look with some numbers
x = 100 (no of employees in the beginning of the quarter)
z = 20 (employees who joined in the quarter)
x+z = 120 which is the number which is achieved at the end of quarter
(2x+z)/2 = 110 is the number which is mid point of the quarter, in my view it is more realistic to report quarter figure on the total employee figure in the middle of the quarter.
