What Is Attrition Rate?

Formula Example

Step-by-step Calculation Guide
Calculating the attrition rate helps track employee turnover in a company. It shows how many employees leave over a period. This guide breaks down the process into simple steps. Follow these steps to get clear, useful results.
Gathering Employee Data
Start by collecting employee records. Note how many employees started and ended the period. Include full-time, part-time, and contract workers if needed. Use accurate, up-to-date data for best results.
Determining Time Period
Choose the time frame for your calculation. Common periods include monthly, quarterly, or yearly. Match the period with your business needs. Consistency helps track trends over time.
Applying The Formula
The basic formula is: (Number of employees who left ÷ Average number of employees) × 100. Calculate the average by adding the number at the start and end, then divide by two. Plug in the numbers and solve.
Interpreting Results
Look at the percentage to understand turnover. A low rate means good employee retention. A high rate may indicate problems. Compare results with industry standards to see where you stand.
Common Mistakes To Avoid
Calculating the attrition rate seems simple, but many make common errors. These mistakes can lead to wrong numbers and poor decisions. Avoiding these errors helps keep your data clear and useful.
Incorrect Time Period Selection
Choosing the wrong time frame affects attrition rate accuracy. Use consistent periods like monthly, quarterly, or yearly. Mixing different time frames causes confusion and wrong results.
Ignoring Employee Types
Counting all employees without distinction can skew results. Separate full-time, part-time, and temporary workers. Each group has different turnover patterns to consider.
Not Accounting For New Hires
Forgetting new hires in the calculation lowers the attrition rate. Always include the average number of employees, factoring in new staff. This gives a balanced view of workforce changes.
Mixing Voluntary And Involuntary Turnover
Combining voluntary resignations with layoffs or retirements hides true attrition reasons. Track these separately to understand why employees leave. This helps target specific problems.
Using Headcount Instead Of Full-time Equivalents
Counting people without adjusting for work hours distorts the rate. Use full-time equivalents (FTE) to standardize employee numbers. This method reflects real workforce size better.
