Attrition Rate Calculator

Our user-friendly attrition rate calculator takes the guesswork out of the process. Simply input a few key numbers:

• Number of separations/departures: This includes employees who have left the company in the chosen timeframe, regardless of reason (resignations, terminations, etc.).
• Number of employees at the start: The total workforce headcount at the beginning of the period you’re analyzing.
• Number of employees at the end: The total workforce headcount at the end of the period you’re analyzing.

By understanding your attrition rate, you can forecast future talent needs and proactively adjust your hiring and training plans. The calculator provides a data-driven foundation for building effective workforce management strategies.

No, the calculator focuses solely on employee departures. However, you can factor in new hires and promotions when interpreting your results and assessing your overall talent management effectiveness.

Unfortunately, the current version of the calculator focuses on company-wide attrition rates. However, we are working on future versions that will allow for departmental and team-specific analysis.

You only need three pieces of information: the number of separations/departures, the number of employees at the start of the period, and the number of employees at the end of the period.

The calculator assumes a linear relationship between the start and end employee headcounts. This may not be accurate for companies with significant fluctuations in workforce size. Additionally, the calculator does not account for involuntary departures, such as layoffs.

This attrition rate calculator isn’t just for annual calculations. You can also use it to:

• Track your attrition rate monthly: Analyze shorter timeframes to identify seasonal trends or pinpoint specific events impacting employee departures.
• Compare attrition rates across departments: See which teams are experiencing higher turnover and tailor retention efforts accordingly.

Attrition Rate = (No. of separations / Avg. No. of employees) x 100

Avg. No. of Employees = (Number of employees at the start + Number of employees at the end) / 2

Let’s say you had 20 employees leave your company in a year, starting with 70 employees and ending with 50. Plug those numbers into the calculator and you get:

Attrition Rate 

= (20 separations / (70 + 50) / 2) x 100

= (20 / (120 / 2)) x 100

= (20 / 60) x 100

= 33.33%

That’s right, a 33.33% annual attrition rate! Now you have a clear benchmark to measure your progress and implement targeted retention strategies.
