Cumulative Calculation help needed for Churned Customer Rate

Hi Anonymous ,

Please try the following measures:

First Date = 
IF (
    HASONEVALUE ( Orders[Month] ),
    FIRSTDATE (
        DATESINPERIOD ( Orders[order_date], FIRSTDATE ( Orders[order_date] ), -1, YEAR )
    )
)

Last Date = 
IF (
    HASONEVALUE ( Orders[Month] ),
    LASTDATE (
        DATESINPERIOD ( Orders[order_date], LASTDATE ( Orders[order_date] ), -1, YEAR )
    )
)

Firstdate_125 = 
IF (
    HASONEVALUE ( Orders[Month] ),
    FIRSTDATE (
        DATESINPERIOD ( Orders[order_date], MAX ( Orders[order_date] ), -126, DAY )
    )
)

User Base = 
AVERAGEX (
    VALUES ( Orders[Month] ),
    CALCULATE (
        DISTINCTCOUNT ( Orders[Users] ),
        DATESBETWEEN ( 'Date'[Fiscal Date], [First Date], [Last Date] ),
        ALL ( Orders )
    )
)

Bought in 125 Days = 
AVERAGEX (
    VALUES ( Orders[Month] ),
    CALCULATE (
        DISTINCTCOUNT ( Orders[Users] ),
        DATESBETWEEN ( 'Date'[Fiscal Date], [Firstdate_125], [Lastdate_125] ),
        ALL ( Orders )
    )
)

Churned Users = [User Base] - [Bought in 125 Days]

Churn_rate = 
AVERAGEX ( VALUES ( Orders[Month] ), DIVIDE ( [Churned Users], [User Base] ) )

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.
