HR Management knowledge - Turnover Rate

I assume you ask about the staff turnover rate. The following lists out some approaches?

Benchmark Portal calculation for turnover: the percentage derived from dividing: (Total number of staff leaving) / (Total number of staff at the beginning of the period).

Rolling, annualized turnover rate: at the end of each week of the month I look at my staffing numbers and average those numbers for a monthly average. I then total the attrition number for the month as well. I track this monthly on a rolling 12 month period (current 12 months). Dividing the total turnover number by the average number of monthly staff and, factoring that number with the number of months you are tracking, will provide the annualized turnover rate. I track turnover weekly, monthly and annually but I always compute it annualized. For instance, if my total turnover for the 3-month period of Jan-Mar is 10, and average monthly staff is 100, then my annualized turnover is 40% (10 / 100) X (12 / 3). Many use another method of simply looking at a month alone, dividing their turnover by their staff numbers at the end of the month, and multiplying by 12. Although that calculation will get you close, it will always be higher than your true annualized turnover rate.

Annualized turnover rate. This annualized figure provides a consistent basis for comparison and trending. The calculation is as follows:Turnover = (# of agents exiting the job / avg. actual # of agents during the period) x (12 / # mos. in period)

Or (terminations for the month) / (headcount at beginning of month + newhires).
