Hi Seniors,

Can you pls provide formula to calculate avg annual attrition rate.

I have searched on CiteHR but could find only annual attrition rate which is again different from the one we are using.

Below is the formula that we are using to calculate Annual Attrition rate:

Annual Attrition Rate : (Employees left in Current Month * (12/No. of Month))/((Current employee strenghth+Employees at start of the month)/2)

Good Evening,

I believe that this is what you want

Labour Turnover/Attrition=Avg no:of employees left during the period/Total no of employees during the year*100

Annual turnover is computed by adding up the monthly turnover for a 12-month period. Monthly turnover is first calculated as the number of employee separations during one month divided by the average number of active employees during the same period.

Monthly Turnover Rate = Number of separations during the month/Average number of employees during the month

x 100

Everyone has different formula what suite them I will try to give you the generic formula

Let me first explain the terms first.

Monthly attrition rate the rate of attrition for that month. It can calculated as

No of people left during the month / avg No of people employed during the month

Avg No of people employed can be calculated by adding (opening headcount+closing headcount)/2

Annualized attrition is term which is described to arrive at projected attrition on annual basis if this trend continues. In this current case you multiply the above with 12 and you get "Annualised attrition" This is projected figure only. If you are doing this month over month then you can take the past months actual data.

Lets take the example that we are computing in May 31st and calendar starts from Jan.

We Sum Avg people employed in Jan+Feb+Mar+Apr+May

Sum people left in Jan+Feb+Mar+Apr+May

apply the same formula but before multiplying with 12 divide by 5 to get annualised No.

You can get actual No. for last 12 months if you have data for last 12 month. When you have data for last 12 months, it is called "Annual Attrition". This is the figure of actual and did not have any projected element into this. For arriving at this you do not multiply with 12 as since you have the actual data for last 12 months.

Hope you have understood the difference of annualised Vs annual attrition as well.

Karthick made a good speadsheet. I added an extra line to show the total attrition rate for the year. You can change the dates as needed for whatever 12 month total you need. Safetyforall

ATTRITION ANALYSIS or ATTRITION RATE

Attrition = ((no. of attrition/left emp.*100)/(actual emp. + new joinee))/100

Formulas: =((F6*100)/(D6+E6+F6+G6))/100 this is for first month.

= ((F7*100)/(D7+E7))/100 this is for second month.

= ((F8*100)/(D8+E8))/100 continues like this.

(The formula and correct logic behind calculation of ATTRITION RATE)

=((no. Of attritions x 100) / (Actual Employees + New Joined)) /100.

Examples:

1) Actual Employees No. Of people left No. Of Joined Total Employees

(Opening BAL) (Attritions) (Current Headcount)

150 20 25 155

So according to the formula: ((20 x 100) / (150 + 25)) / 100

Which comes to 0.1142 i.e. 11%

Now as you had 150 previously and now 25 joined so it makes 150 + 25 =175

Now if you calculate 11.42% of 175 i.e. 175 x 0.1142 = 20

This clearly shows that 175 – 20 = 155, which is your current headcount and at the same time you can say my attrition is 11.42% that shows you lost 20 employees of 150 and 25 more joined which makes count to 175.
