Understanding Monthly Turnover Rate
Employee turnover is a critical metric for Human Resources departments and business owners. It represents the percentage of employees who leave an organization during a specific period. While some turnover is inevitable, a consistently high rate can indicate underlying issues with company culture, compensation, or management, leading to increased recruitment and training costs.
This Monthly Turnover Rate Calculator helps you quickly assess workforce stability by comparing the number of employees leaving against your average workforce size.
How to Calculate Monthly Turnover Rate
The standard formula used by HR professionals to calculate monthly turnover is straightforward but requires accurate data regarding your headcount at the beginning and end of the month.
Formula:
Turnover Rate = (Number of Separations / Average Number of Employees) × 100
Where Average Number of Employees = (Employees at Start + Employees at End) / 2
Step-by-Step Calculation Example
Let's say you want to calculate the turnover rate for the month of November:
- Start Count: You had 200 employees on November 1st.
- End Count: You had 196 employees on November 30th.
- Separations: During the month, 6 employees left the company.
Step 1: Calculate the Average Workforce
(200 + 196) / 2 = 198 average employees.
Step 2: Divide Separations by Average
6 / 198 = 0.0303
Step 3: Convert to Percentage
0.0303 × 100 = 3.03% Monthly Turnover Rate.
Interpreting Your Results
Once you have your monthly percentage, it is often helpful to look at the Projected Annual Turnover. This is calculated by multiplying your monthly rate by 12. In the example above, a 3.03% monthly rate suggests an annualized turnover of roughly 36.36%, assuming the trend continues.
What is a "Good" Turnover Rate?
There is no single magic number, as turnover varies significantly by industry. For example, the retail and hospitality sectors often see higher turnover rates compared to government or utility sectors. However, a general rule of thumb across all industries is to aim for an annual turnover rate of roughly 10%.
Why Tracking Separations Matters
Regularly using a turnover rate calculator allows organizations to:
- Identify Trends: Spot if turnover spikes during specific months or after specific policy changes.
- Calculate Costs: Estimates suggest that replacing an employee can cost 1.5 to 2 times their annual salary.
- Improve Retention: High data visibility prompts leadership to implement retention strategies, such as better onboarding or benefits packages.
Voluntary vs. Involuntary Turnover
When inputting data into the calculator, you may choose to include all separations or filter them based on type:
- Voluntary Turnover: Employees leaving of their own accord (resignation, retirement). High voluntary turnover often points to cultural or compensation issues.
- Involuntary Turnover: Employees terminated by the company (layoffs, performance-based firing).
For the most accurate health check of your company culture, consider running the calculation using only voluntary separations.
