Understanding Employee Attrition: What's the Standard Formula for Calculation?

My question is how to calculate employee attrition rate and any standard formula to calculate attrition rate.

With regards,

Ramu,

You can find out the attrition percentage by the method below:
No. of People Resigned / Current Headcount + New Joinees - No. of People Resigned.

Number of separations during the period divided by the average number of employees during the period, multiplied by 100.

Average number of employees during the period is calculated as the sum of the number of employees at the beginning of the period and the number of employees at the end of the period, divided by 2.

Hi Ramu,

Please refer to this document for finding the Attrition Rate. I have come across this on CITEHR itself.

Hi,

You can calculate using the formula below:
- Number of employees left: X
- Number of employees joined: A
- Opening headcount during that period: B
- Average headcount (C): (A + B) / 2
- Attrition rate: (X / C) * 100

Hi Ravi & Khyat,

I have a doubt dealing with the following: internal promotion for career progression, which creates vacancies for the same profile and employees moving to another business of the same company. Even when calculating the new joiners, do we need to consider only the permanent employees or also include contracted ones? Kindly explain to me.

If you have an answer, kindly send me the updates through [Login to view].

I guess the simple way should be:

First, take out the Average Headcount (Opening Headcount + Closing Headcount/2).

Quarterly Attrition = Number of people Attrited/Average Headcount * 4.

Annually Attrition = Number of People Attrited/Average Headcount * 12.

Hope this helps.
