How to Calculate Attrition Rate in Excel: A Step-by-Step Guide

Calculating the attrition rate in Excel involves a few simple steps. First, gather your employee data including the number of employees at the start and end of a period, as well as the number of employees who left during that period. Next, use the formula: (Number of Employees who Left / Average Number of Employees) x 100 to calculate the attrition rate. Plug these values into Excel to perform the calculations automatically.

How to Calculate Attrition Rate in Excel

This section will guide you through the steps to calculate the attrition rate in Excel, ensuring you have a clear understanding of how to gather data, input formulas, and interpret the results.

Step 1: Gather Employee Data

Collect the number of employees at the beginning and end of the period, and the number of employees who left during that period.

Begin by noting the number of employees you started with at the beginning of the chosen period, the number of employees remaining at the end, and those who left in between. Accurate data is key here, so double-check your numbers to avoid errors.

Step 2: Calculate Average Number of Employees

Calculate the average number of employees using the formula: (Employees at Start + Employees at End) / 2.

In Excel, use a cell to input the formula. For example, if you have 50 employees at the start (cell A1) and 45 at the end (cell B1), the formula in cell C1 would be: =(A1+B1)/2. This gives you the average number of employees during the period.

Step 3: Input the Number of Employees Who Left

Enter the number of employees who left during the period into another cell.

For instance, if 5 employees left during the period, you might place this number in cell D1. This data point is crucial for the next calculation.

Step 4: Use the Attrition Rate Formula

Apply the formula: (Number of Employees who Left / Average Number of Employees) x 100 in Excel.

In a new cell, use the formula to find the attrition rate. For example, in cell E1, use: =(D1/C1)*100. This formula calculates your attrition rate as a percentage.

Step 5: Interpret the Results

Look at the result to understand your attrition rate.

The value you get in cell E1 is your attrition rate, expressed as a percentage. A higher percentage might indicate a retention problem, while a lower rate suggests better employee stability.

After completing these steps, you’ll have a clear picture of your company’s attrition rate. This percentage helps you understand your employee turnover and can be a vital metric for improving retention strategies.
