How Is Employee Turnover Rate Calculated?

Employee turnover rate is a critical metric for HR professionals and business owners, representing the percentage of employees who leave an organization during a specific time period. Understanding how to calculate this figure helps organizations assess their retention strategies, workplace culture, and overall stability.

The Core Formula

To calculate the employee turnover rate, you need three key pieces of data: the number of employees at the start of the period, the number of employees at the end of the period, and the total number of separations (employees who left) during that period.

The standard formula used globally is:

Turnover Rate = (Total Separations / Average Number of Employees) × 100

Where the Average Number of Employees is calculated as:

Average Employees = (Start Count + End Count) / 2

Step-by-Step Calculation Guide

1. Determine the Time Period: Decide if you are calculating monthly, quarterly, or annual turnover.
2. Get the Starting Count: How many employees were on the payroll on the first day?
3. Get the Ending Count: How many employees were on the payroll on the last day?
4. Count Separations: Tally the total number of employees who left the company (voluntarily or involuntarily) during this timeframe.
5. Calculate Average: Add the start and end counts, then divide by 2.
6. Divide and Multiply: Divide the separations by the average count, then multiply by 100 to get a percentage.

Real-World Example

Scenario: A tech company wants to calculate its Q1 turnover rate.

• Employees on Jan 1st: 150
• Employees on Mar 31st: 160
• Separations (Jan-Mar): 8

Step 1 (Average): (150 + 160) / 2 = 155 Average Employees

Step 2 (Rate): (8 / 155) × 100 = 5.16%

Why Is This Calculation Important?

Tracking how employee turnover rate is calculated provides actionable insights into the health of an organization. A high turnover rate can indicate issues with compensation, management, or company culture, leading to increased recruitment and training costs. Conversely, a very low turnover rate might suggest stagnation.

What to Include in "Separations"

When inputting data into the calculator, "separations" should typically include:

• Voluntary Turnover: Resignations, retirement.
• Involuntary Turnover: Terminations, layoffs.

Usually, temporary leaves of absence or internal transfers are excluded from this calculation to ensure accuracy.

Interpreting Your Results

While benchmarks vary by industry, a healthy turnover rate is generally considered to be roughly 10%. However, industries like retail and hospitality often see rates as high as 60% or more. Comparing your calculated rate against your industry average is the best way to gauge performance.
