What is Attrition Rate?

Attrition rate refers to the rate of people leaving an organization or company due to various factors. A low attrition rate suggests that something needs to be taken care of in the company. It is affected by various factors such as the work environment, perks, and benefits etc.

Companies with a low rate of attrition tend to suffer from poor performance, lower productivity, lower-quality service, etc. The BPO industry is very much affected by these factors as it is service-based. 

Thus, it is important to keep track of the attrition rate in BPO.

How to Calculate Attrition Rate in BPO?

Measuring the attrition rate is the first step toward taking corrective measures. Here is the simple attrition rate formula in BPO:

Attrition Rate (%) = (Number of Employees Who Left ÷ Average Number of Employees) × 100

Simple steps to use the attrition formula in BPO:

Step 1: Select the period for which you want to calculate the attrition rate.

Step 2: Count the total number of employees at the beginning and the end of a selected time period.

Step 3: Calculate the average by adding the total number of employees at the beginning and the end, and then dividing the result by 2

Step 4: Divide the number of employees who left the company in this period by the average you calculated earlier.

Step 5: Multiply the result by 100, and you’ll get the attrition rate of your company in that chosen time period.

If it seems complicated, let me explain it to you with an example. It’ll clear all the steps on how to use the attrition rate formula.

Example for calculating the Attrition Rate for one year:

  • Number of employees at the start of the year: 200
  • Number of employees at the end of the year: 180
  • Average employees = (200 + 180) ÷ 2 = 190
  • Employees who left = 200 – 180 = 20

Now, put these numbers in the Attrition formula

Attrition Formula

Attrition Rate = (20 ÷ 190) × 100 = 10.5%

10.5% is the annual attrition rate in this example. Similarly, you can calculate monthly as well as quarterly rates.

Common Mistakes When Calculating the Attrition Rate

Though calculating attrition is no difficult task. But even a minor mistake can lead to wrong figures. Here are some common mistakes that you must take care of:

  • Not calculating the average number of employees correctly.

  • Time period not selected for the measurement.
