How does Workforce Intelligence and calculate turnover?

How we track your data
Workforce Intelligence tracks employees of each of our member companies through a monthly census. We use this feed to see where the employees are moving throughout the organization. If an employee falls off the census, they get counted as a termination. If their position changes from say an Assistant Manager to a General Manager, they are counted as a management promotion. Because of the level of detail we receive, we are able to provide comprehensive transaction (termination, hire, promotion) information including breakouts of demographic and compensation data along with the detail that we provide for the incumbent population of employees.

Transaction rates (turnover, hire, promotion)
We calculate transactions by adding up counts for each month to create the different rates that we provide to our in our suite of reports. For instance, the 'your company' number that you see for monthly hourly turnover is the count of all of the hourly terminations for that month divided by the count of the hourly incumbent population for that month.

Monthly turnover rate
= (sum of terms for month) / (count of incumbent population for month)

Getting into bigger time frames, the quarterly hourly turnover rate for example is the count of terminations across three months of the calendar year divided by the average count of hourly employees in the incumbent population.

Quarterly turnover rate
= (sum of terms for month 1, month 2, month 3) / (average of count of incumbent population for month 1, month 2, month 3)

This same methodology applies to the larger time frames like the 'rolling year' rates (count of terminations during the last 12 months divided by the average count of incumbent population for those 12 months). We use the same methodology across the different cuts of the population (total workforce turnover, Assistant Manager turnover) as well as to calculate the hire and promotion rates.

Rolling Year turnover rate
= (sum of terms for months of calendar year up to reporting month) / (average of count of incumbent population for months of calendar year up to reporting month)

YTD turnover rate
= (sum of terms for months of calendar year up to reporting month) / (average of count of incumbent population for months of calendar year up to reporting month)

Annual turnover rate
= (sum of terms for all months in calendar year) / (average of count of incumbent population for all months of calendar year)
