Monthly Weighted Average with a filter

Hi, 

I need to created a weighted average visual using the below example data

SegmentDate  AccountRateBalance
West1/01/20211230.7726 $804.86
West1/01/20214560.6198 $484.39
West1/02/20211230.0565 $607.85
West1/02/20214560.8504 $587.12
West1/03/20211230.3875 $701.91
West1/03/20214560.9706 $484.95
East1/01/20217890.6573 $668.76
East1/01/20211010.6411 $586.13
East1/02/20217890.2642 $438.20
East1/02/20211010.6951 $111.90
East1/03/20217890.3067 $790.21
East1/03/20211010.2478 $407.28


The Base is Rate.
Weight is Balance, aggregated across all accounts within each month. 
The visual will filter by Segment and the weighted average will need to update for the filter. 

For instance, with the filter Segment = "West", the desired table would look like this

SegmentDate  AccountRateBalanceTotalWeightWeighted Value
West1/01/20211230.7726 $804.86 $1,289.25     0.62        0.48
West1/01/20214560.6198 $484.39 $1,289.25     0.38        0.23
West1/02/20211230.0565 $607.85 $1,194.97     0.51        0.03
West1/02/20214560.8504 $587.12 $1,194.97     0.49        0.42
West1/03/20211230.3875 $701.91 $1,186.86     0.59        0.23
West1/03/20214560.9706 $484.95 $1,186.86     0.41        0.40

Total is a sum of Balance, summarised by Date, Weight is Balance/Total and Weighted Value is Weight*Rate.

The visual data for "West" would look like this

 Weighted Average
1/01/2021     0.72
1/02/2021     0.45
1/03/2021     0.63

Where Weighted Average is the sum of the Weighted Values for each Date.


Any help is appreciated, thanks.

    Hi Adam_Cromie 

     

    For your question, here is the method I provided:

     

    Here's some dummy data

     

    "Table"

     

    Create measures.

     

    Total = 
CALCULATE(
    SUM('Table'[Balance]), 
    FILTER(
        ALLEXCEPT('Table', 'Table'[Segment]), 
        'Table'[Date] = MAX('Table'[Date])
    )
)

     

    Weight = DIVIDE(SELECTEDVALUE('Table'[Balance]), 'Table'[Total])

     

    Weighted Value = SELECTEDVALUE('Table'[Rate]) * 'Table'[Weight]

     

    Weighted Average = 
SUMX(
    FILTER(
        ALLSELECTED('Table'), 
        'Table'[Date] = MAX('Table'[Date])
    ), 
    'Table'[Weighted Value]
)

     

    Here is the result.
