10.00% is the example result. Read it using the units and relationship stated below.
Employee Turnover uses employee departures, average headcount.
Reading capacity and cost without hiding the workload
For employee turnover, the relationship is Result = (([Employee departures]) ÷ ([Average headcount])) × 100. The amount depends on the supplied employee departures, average headcount, rather than a live market price or a value imported from another record. A staffing plan needs available hours and the portion of those hours that can serve the intended work. Paid time, productive time and billable time are separate definitions. Recruiting, training and supervision can change the cost of a role.
What the model includes
Result = (([Employee departures]) ÷ ([Average headcount])) × 100 Use one team and one reporting period. Headcount measures should distinguish people from full-time equivalents; hour-based models should state the expected schedule. A temporary absence and a permanent vacancy have different operating consequences. Review the result with the work queue and service commitment. A high utilisation percentage can signal limited room for urgent work, rather than a reason to add more demand immediately.
Example with the supplied inputs
Employee departures: 12; Average headcount: 120. Result: 10.00%. The values are illustrative.
Compare one changed input
Employee departures changes from 12 to 13.2. The result becomes 11.00%. All other inputs remain fixed.
Calculation rule
Result = (([Employee departures]) ÷ ([Average headcount])) × 100
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Employee departures | 12 | Use the source quantity represented by employee departures. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Average headcount | 120 | Use the source quantity represented by average headcount. Keep the counted population fixed and avoid mixing a unit value with a period total. |
Output: 10.00% is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Employee departures, Average headcount. Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Employee departures on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 10.00%.
Change Employee departures from 12 to 13.2 while keeping every other value fixed. The result becomes 11.00%. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
