Hi JACK__ ,

According to your description, here are my steps you can follow as a solution.

(1) This is my test data.

(2) We can create a calculated column.

Change = 
IF (
    [Week]
        = CALCULATE (
            MIN ( 'Table'[Week] ),
            FILTER ( ALL ( 'Table' ), 'Table'[Item] = EARLIER ( 'Table'[Item] ) )
        ),
    BLANK (),
    [Price]
        - CALCULATE (
            SUM ( 'Table'[Price] ),
            FILTER (
                'Table',
                'Table'[Item] = EARLIER ( 'Table'[Item] )
                    && 'Table'[Week]
                        = EARLIER ( 'Table'[Week] ) - 1
            )
        )
)

(3) Then the result is as follows.
