monthly attrition % dynamically

[pawanmtm]

Hi All,

I have a table that has Employee name, Date of Joining and Date of Last Working day.  I want to calculate the attrition % as mentioned below:

Link for sample data: https://drive.google.com/file/d/1QrL3JvPDh_WgvvVWxiSTtokNKQBetLNb/view?usp=sharing

Name	Date of Joining	Last working day
Alexis Valenzuela	16-Mar-20
Erasmo Gonzalez	02-Mar-20
Michelle Carrasco	02-Mar-20
Lisa Zubia	02-Mar-20
Christopher A Fernandez	16-Mar-20
Donna Hammond	26-May-20
Karen-Gabriela Medina-Gamboa	16-Mar-20

Months	Attrition	Attrition%
Jan'20	60	14%
Feb'20	11	2%
Mar'20	0	0%
Apr'20	4	1%
May'20	1	0%
Jun'20	27	5%
Jul'20	16	3%
Aug'20	8	1%
Sep'20	21	2%
Oct'20	66	5%
Nov'20	19	1%
Dec'20	0	0%

Here are the excel formula's used to arrive the desired output

Attrition	COUNTIFS(Sheet1!$C:$C,">="&A3,Sheet1!$C:$C,"<="&EOMONTH(A3,0))
Attrition%	B3/(COUNTA(Sheet1!$A:$A)-1-COUNTIF(Sheet1!$B:$B,">="&A3))

i have created measure "leaverscount = COUNT('MDB Data'[Last working day ])" to get Attrition count, but stuck with Attrition% as it is dynamic.

I tried few things like creating year and month columns, merge as new one and then get the count less than or equal to that month, but couldn't get it.

Any help on this is much appreciated.

Regards,

Pavan
