How to Calculate Attrition Rate in Excel

Calculating the attrition rate (also known as churn rate) is essential for HR departments to understand workforce stability. While the calculator above provides an instant result, doing this in Microsoft Excel allows for tracking across multiple departments or time periods.

The Attrition Rate Formula

The standard formula used for attrition is:

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

Step-by-Step Excel Instructions

  1. Organize your data: Set up your columns as follows:
    • Cell A2: Starting Headcount
    • Cell B2: Ending Headcount
    • Cell C2: Number of Employees Left
  2. Calculate Average Headcount: In cell D2, enter the formula: =(A2+B2)/2.
  3. Calculate the Rate: In cell E2, enter the final formula: =C2/D2.
  4. Format as Percentage: Select cell E2 and click the % button on the Home tab of the Excel ribbon to convert the decimal to a percentage.

Real-World Example

Imagine your company started the year with 200 employees and ended with 190. During that year, 25 people left the company. Here is how you would calculate it:

  • Average Headcount: (200 + 190) / 2 = 195
  • Attrition Calculation: 25 / 195 = 0.1282
  • Result: 12.82% Attrition Rate

Why Attrition Rate Matters

A high attrition rate often indicates issues with company culture, compensation, or management. By using Excel to track this monthly, you can identify seasonal trends or specific departments that may need additional support or policy changes to improve retention.
