    Hi sensemaker14 ,

    I adjust something, please try below steps:

    1. add a new column with below dax formula

    RK =
VAR cur_year = [Year]
VAR tmp =
    FILTER ( ALL ( 'Table' ), 'Table'[Year] = cur_year )
RETURN
    RANKX ( tmp, [Index],, ASC, DENSE )

    2. use this dax formula to replace above same name measure

    Adjust Contribute =
VAR cur_rk =
    SELECTEDVALUE ( 'Table'[RK] )
VAR cur_year =
    SELECTEDVALUE ( 'Table'[Year] )
VAR cur__ct =
    CALCULATE (
        MAX ( 'Table'[Contributed Capital] ),
        'Table'[RK] = cur_rk
            && 'Table'[Year] = cur_year,
        ALL ( 'Table' )
    )
VAR pre_ct =
    CALCULATE (
        MAX ( 'Table'[Contributed Capital] ),
        'Table'[RK] = cur_rk - 1
            && 'Table'[Year] = cur_year,
        ALL ( 'Table' )
    )
RETURN
    IF ( cur_rk = 1, 0, cur__ct - pre_ct )

    3. then you could get the output

    Please refer the attached .pbix file.

Hi sensemaker14 ,

As my above screenshot show, please refer "Income add Contribute" measure, the logic of his calculation is consistent with what you said.

Hi Anonymous 
I don't know how to attach the .pbix like you did, it errors and says the file type isn't allowed. 

 

But the only thing I'm missing is the initial ignore.

 

Adjusted Contribute =
var current_index=SELECTEDVALUE('Table'[Index])
var current__capital=CALCULATE(MAX('Table'[Contributed Capital]),'Table'[Index]=current_index,ALL('Table'))
var previous_capital=CALCULATE(MAX('Table'[Contributed Capital]),'Table'[Index]=current_index-1,ALL('Table'))
return
current__capital-previous_capital
