Accumulated Turnover Percentage

[marksmith12]

Good Morning,

Looking for some assistance on a calculation on Accumulated Turnover percentage. I am trying to show our turnover percentage accumulated for each month for the fiscal year. So essentially, the previous month's (or months depending on the time interval) turnover percentage plus the each subsequent month following. Here is the calculation I am using:

(Count({$<Days_Employed_Key = {1,2,3},FYFlag={1}>} distinct Employee_Id))
/ (((Sum(TOTAL Aggr(Sum({$<FYFlag={1},MonthOffset={">0"}, Company_Code -={77,75}>}(Present_First_Of_Month+Present_Last_Of_Month)))/2))))

Any assistance would be appreciated.

Thanks,

Mark
