DAX: Calculate Hires and Terminations

[jdevries192]

Hi All,

Looking to calculate with DAX new hire retention in a given month based on an activity table. Issue is an employee may be hired and terminated many times (see employee 1 in example below). So I can't pivot the table to determine hire and termination dates in a given timeframe.

Calculation is (Ending Month's Continuous Headcount / Starting Month's Headcount)

Example Data below:

Employee	Activity	Date
1	Hire	1/1/2022
2	Hire	1/1/2022
1	Termination	1/5/2022
3	Hire	1/31/2022
4	Hire	1/31/2022
3	Termination	2/2/2022
1	Hire	2/5/2022
2	Termination	2/5/2022
1	Termination	2/6/2022
1	Hire	2/20/2022

For February, Employees 2, 3, and 4 were active at the start of the month. But only Employee 4 was active at the start and end of the month. So the calculation would be:

1/3 = 33%.

Any help would be appreciated.

@jdevries192 , With help from date table joined to your date of the table

Active Employees = calculate(distinctCOUNT(EmpData[ID]) , filter(EmpData, EmpData[Date] <= max(Date[Date]) && [Activity] = "Hire" ))
- calculate(distinctCOUNT(EmpData[ID]) , filter(EmpData, EmpData[Date] <= max(Date[Date]) && [Activity] = "Termination" ))

@amitchandak 

You are counting all hires and terminations.

I need those who are still active at the start of February (who have been hired but not terminated). And I need those who were active at the start of February and who are still active at the end of February.
