Calculation on headcount and leavers_moving average

Hello everyone, 

 

Thank you for viewing my post.

 

My question is how do I calculate number of leavers between period Oct 2021 to Sept 2022 divided by ((starting headcount e.g. Oct 2021 + ending headcount Sept 2022)/2)?
And then,  number of leavers between period Nov 2021 to Oct 2022 divided by ((starting headcount e.g. Nov 2021 + ending headcount Oct 2022)/2), etc?

I have the following data:

Starting headcount (number of employees at the start of the month), ending headcount (number of employees end of the month), number of leavers- they are all separate tables.

Starting headcount (Month/Year), Ending headcount (Month/Year)and Leavers(Termination start of month (Month/Year) are linked to the Calendar (Month/Year) table.
Starting headcount Oct 2021: 6500
                                Nov 2021: 6800
Ending headcount Sept 2022: 5400

                               Oct 2022: 5200
Leavers : Oct 2021 - Sept 2022 is 2380

               Nov 2021 - Oct 2022 is 2400

So my calculation for Oct 2021 - Sept 2022 would be:
2380 / (6500+5400)/2) * 100

Any help is very much appreciated

    Hi anony711 ,

     

    First we need a calendar table like:

    relationships:

    Please try:

    Measure = 
VAR _min_date = MIN('Calendar'[Date])
VAR _max_date = EDATE(_min_date,12)
VAR _start_monthyear = MAX('Calendar'[MonthYear])
VAR _end_monthyear = CALCULATE(MAX('Calendar'[MonthYear]),FILTER(ALL('Calendar'),'Calendar'[Date]=_max_date-1))
VAR _leavers = CALCULATE(SUM('Table3'[Number of leavers]),FILTER(ALL('Calendar'),'Calendar'[Date]>=_min_date&&'Calendar'[Date]<_max_date))
VAR _number_of_employees_at_the_start = CALCULATE(MAX('Table1'[Starting headcount]),'Calendar'[Date] = _min_date)
VAR _max_date_2 = CALCULATE(MAX('Table2'[Date]),FILTER(ALL('Table2'),'Table2'[Date]<_max_date))
VAR _number_of_employees_at_the_end = CALCULATE(MAX('Table2'[Ending headcount]),'Calendar'[Date] = _max_date_2)
VAR _result = DIVIDE(_leavers,(_number_of_employees_at_the_start+_number_of_employees_at_the_end)/2)
RETURN
_result
