Percent difference calculation using different values

[Anonymous]

Hi there!

I am looking for some help with my dax:

I have a very simplified dataset and I want to calculate the percent difference (V2-V1)/V1 . I would like a way to calculate the percent difference based off of different reference values: AVGstatic, AVGmonthly (calculated). I would only like to have 1 column called 'Percent difference' , but I don't know how to filter the table properly. 

Thank you for your help.

OUTPUT: 

AVGstatic = 6

TABLE 1:

Date	Bananas Eaten	Percent difference
1.1.2024	6	0
1.2.2024	7	17%
1.3.2024	8	33%

AVGMonthly = 10

TABLE 1:

Date	Bananas Eaten	Percent difference
1.1.2024	6	-40%
1.2.2024	7	-30%
1.3.2024	8	-20%

Hi @Anonymous ,

You can try dax like below:

M1 =
VAR cur =
    IF (
        NOT ISBLANK ( SELECTEDVALUE ( slice[tag] ) ),
        SELECTEDVALUE ( slice[value] ),
        BLANK ()
    )
RETURN
    ( MAX ( 'Table'[Bananas Eaten] ) - cur ) / cur
