This interactive employee attrition rate calculator allows you to easily calculate your organisation’s attrition rate over a given period. The attrition rate is a key metric that measures the percentage of employees who have left the company during that time.

  1. Employees at the Start: Enter the number of employees at the beginning of the time period you want to analyze.
  1. Employees at the End: Enter the number of employees at the end of the time period.
  1. Employees that Left: Enter the number of employees that left the company during that time period.

The calculator will automatically compute the attrition rate based on these three values. The attrition rate is displayed as a percentage.

  • All input fields require positive integer values. Negative or zero values will result in an error.
  • The “Employees at the End” value cannot be greater than the “Employees at the Start” value.
  • The “Employees that Left” value cannot be greater than the “Employees at the Start” value.

What is the Employee Attrition Rate?

Employee attrition rate is a metric that measures the percentage of employees who leave an organization over a given period of time. It is an important indicator of employee retention and can provide insights into the overall health and stability of a company’s workforce.

Attrition can occur for a variety of reasons, including:

  • Voluntary resignations
  • Retirements
  • Terminations
  • Layoffs
  • Relocations
  • Death

Tracking and analyzing employee attrition rates can help organizations identify problem areas, implement retention strategies, and make informed decisions about their workforce management.

How to Calculate Employee Attrition Rate

The formula to calculate the employee attrition rate is:

Attrition Rate = (Number of Employee Exits / Average Number of Employees) x 100

Here’s a step-by-step breakdown of the calculation:

  1. Determine the Number of Employee Exits: This includes all employees who have left the organization during the specified time period, regardless of the reason for their departure.
  1. Calculate the Average Number of Employees: This is the average number of employees on the payroll during the same time period. You can calculate this by adding the number of employees at the beginning and end of the period, then dividing by 2.

    Example:

    • Number of employees at the start of the period: 100
    • Number of employees at the end of the period: 95
    • Average number of employees = (100 + 95) / 2 = 97.5
    1. Apply the Formula: Plug the values into the formula:
    Attrition Rate = (Number of Employee Exits / Average Number of Employees) x 100
    Attrition Rate = (5 / 97.5) x 100 = 5.13%

    In this example, the employee attrition rate is 5.13%.

    Interpreting Employee Attrition Rate

    Employee attrition rates can vary significantly across industries and organizations. Generally, a lower attrition rate is desirable as it indicates higher employee retention and stability. However, some degree of turnover is normal and even healthy, as it can bring in new ideas and perspectives.

    When analyzing the attrition rate, consider the following:

    • Industry Benchmarks: Compare your organization’s attrition rate to industry averages to understand how you’re performing relative to your peers.
    • Voluntary vs. Involuntary Attrition: Distinguish between voluntary resignations and involuntary terminations, as they may require different retention strategies.
    • Reasons for Leaving: Gather exit interview data or conduct surveys to understand the primary reasons employees are leaving, such as compensation, career growth, work-life balance, or management issues.
    • Impact on Operations: High attrition rates can disrupt productivity, increase training costs, and negatively impact team morale and institutional knowledge.
    • Demographic Trends: Analyze attrition patterns across different employee demographics, such as age, tenure, department, or job function, to identify any underlying issues.

    By understanding and monitoring employee attrition rates, organizations can develop targeted retention strategies, address pain points, and build a more stable and engaged workforce.
