    Hi Anonymous,

    Based on your answer I re-write formula and got what I needed (this refers to the previous year; the formula for the current year remains the same): 

     

    AVG Rent Studio PY =
IF (
    HASONEVALUE ( 'Rental Trend'[Year] ),
    CALCULATE (
        AVERAGE ( 'Rental Trend'[Rent] ),
        FILTER (
            ALL( 'Rental Trend' ),
            'Rental Trend'[Year]
                = MAX( 'Rental Trend'[Year] ) - 1
        ),
        VALUES ( 'Rental Trend'[Type] )
    )
)

    This piece of formula filtered a previous year:

    PY = MAX( 'Rental Trend'[Year] ) - 1

     

     

    Year to year change:

    AnnualChange = 1 - DIVIDE([AVG Rent PY], [AVG Rent CY])

    Thank you.

Let me ask this in another way. Using the above table I calculated an average rent using this formula (for "Studio" type):

AVGRentStudio = CALCULATE(AVERAGE('Rental Trend'[Rent]),'Rental Trend'[Type] = "Studio")

And I presented the average values per year in tabular form:

 

Now, I would like to show the percentage change (compared to the previous year). Can anyone help to achieve this?

 

Thanks,

    Hi LakiCG,

     

    You can try to use below measure if it works for your scenario:

    Change % with Prev Year =
VAR _Curr =
    CALCULATE (
        AVERAGE ( Table1[Rent] ),
        VALUES ( Table1[Geo-Location] ),
        VALUES ( Table1[Year] )
    )
VAR _prev =
    CALCULATE (
        AVERAGE ( Table1[Rent] ),
        FILTER (
            ALLSELECTED ( Table1 ),
            Table1[Year]
                = SELECTEDVALUE ( Table1[Year] ) - 1
        ),
        VALUES ( Table1[Geo-Location] )
    )
RETURN
    DIVIDE ( _Curr - _prev, _prev, -1 )
