Employee Attrition Rate - ZingHR

Employee attrition rate is a metric that measures the rate at which employees leave a company over a certain period. It is when an organization gradually loses its employees and fails to replace them with new ones. Yes, you read it right, employee attrition means a permanent reduction in your workforce.

Imagine you run a Tech firm. Over a year, four of your senior employees exit the organization, two make a job switch, one retires, and one person gets laid off. Now you’ve only been able to hire two people to replace the four who’ve left you. This steady rate of reduction in your workforce is known as the employee attrition rate.

How do you Calculate the Employee Attrition Rate?

Now that you know about employee attrition, let’s get into the numbers. Calculating your employee attrition rate is quite easy. You need two key figures to calculate it i.e. the number of employees who’ve left your organization and the average size of your workforce during that period.

Here’s the Employee Attrition Rate Formula to calculate it accurately:

Number of employees who left ÷ Average number of employees × 100 = Attrition Rate %

Here’s an example to help you understand this better. Imagine your organization had 120 employees at the start of the year and 110 by the end of it.

That means the average workforce of your organization that year was 115 employees. Now if 10 people left your organization that year, your organization’s employee attrition rate would be: 10 ÷ 115 × 100 = 8.7 %

After understanding the causes and solutions for attrition, it’s crucial to differentiate between similar terms often used interchangeably: turnover rate, retention rate, and churn rate.

1. Turnover Rate

The turnover rate measures the percentage of employees who leave an organization over a specific period.

Turnover Rate Calculation\=

Average Number of Employees During the Period

______________________________________________________ ×100

Number of Employees Who Left During the Period​

Example:

If 15 employees left in a year and the average number of employees during the year was 200:

Turnover Rate\=

200

_________ ×100=7.5%

15​

2. Retention Rate

The retention rate indicates the percentage of employees who stay with an organization over a specific period.

Retention Rate Calculation\=

Number of Employees at the Start of the Period

__________________________________________________ ​×100

Number of Employees at the End of the Period

Example:

If a company started the year with 150 employees and had 140 employees remaining at the end of the year.

Retention Rate\=

150

_______ ×100=93.3%

140​

3. Churn Rate

The churn rate measures the percentage of employees who leave the company during a given period, similar to the turnover rate but can also apply to other entities like customers.

Churn Rate\=

Total Number of Employees at the Start of the Period

____________________________________________________ ×100

Number of Employees Who Left​

Example:

If a company began the year with 300 employees and 30 employees left during the year:

Churn Rate\=

300

____ ×100=10%
30​

Conclusion

Now let’s be honest, reducing your organization’s employee attrition rate isn’t just about statistics. It’s much more than just numbers, it’s about creating an atmosphere, a culture where people want to stay for a long period of time. It’s about creating a place that feels like home and the teams feel like a family, it should be more than just a workplace.
