How to Calculate Attrition Rate in BPO & Call Center

BPOs and Call centers consists of both voice and non voice processes. Here’s how you can calculate the Attrition Rate step by step:

  1. Determine the period for which you want to calculate the attrition rate (e.g., monthly, quarterly, or annually).
  2. Count the number of employees who left the company during that specific period. Let's call this number "Number of Employees Who Left = N."
  3. Estimate the average number of employees during the same period. 
  4. To find the average, add the total number of employees at the beginning and end of the period, and then divide by 2. Let's call this number "Average Number of Employees = A."
  5. Put the values into the above attrition rate formula and calculate.

For example, if ten employees left, and the average employee count is 200, then the attrition rate would be: 

Thus N=10, A= 100

Attrition Rate Formula= A/N x 100

Attrition Rate = (10/200) x 100= 5%

Finally, Attrition Rate is 5%
