Understanding and Calculating Employee Turnover Rate by Year

Employee turnover rate is a crucial metric for businesses to understand the rate at which employees leave an organization over a specific period. A high turnover rate can indicate underlying issues within the company culture, management, compensation, or career development opportunities. Conversely, a low turnover rate generally suggests a healthy and stable work environment.

Calculating turnover rate by year helps businesses identify trends, assess the impact of changes implemented, and benchmark against industry standards. It's a vital tool for human resources professionals, managers, and leadership to make informed decisions about employee retention strategies.

Why is Calculating Turnover Rate by Year Important?

  • Cost Savings: High turnover is expensive due to recruitment, onboarding, and lost productivity costs.
  • Productivity: Frequent departures disrupt team dynamics and project continuity.
  • Morale: A revolving door of employees can negatively impact the morale of remaining staff.
  • Knowledge Retention: Losing experienced employees means losing valuable institutional knowledge.
  • Employer Branding: High turnover can damage a company's reputation as an employer.

How to Calculate Employee Turnover Rate

The basic formula for calculating employee turnover rate is:

Turnover Rate = (Number of Employees Who Left / Average Number of Employees) * 100

This calculation is typically performed for a specific period, such as a month, quarter, or year.

Calculating Turnover Rate by Year

To calculate the turnover rate for an entire year, you need two key pieces of information:

  1. Number of Employees Who Left During the Year: This includes all employees who voluntarily resigned, were terminated, or retired during the 12-month period.
  2. Average Number of Employees During the Year: This is calculated by summing the total number of employees at the beginning of the year and the total number of employees at the end of the year, and then dividing by two. Some prefer to calculate a monthly average and then average those 12 months for a more precise figure, especially if there are significant fluctuations. For simplicity, we will use the beginning and end of year method.

Once you have these figures, you can plug them into the formula to get your annual employee turnover rate.
