Outstanding Balance calculation

Hi Kolumam2810 ,

Try this:

Column:

Column = 
'Table'[Principal Amount (USD)]
    - SUMX (
        FILTER (
            'Table',
            'Table'[Tranche] = EARLIER ( 'Table'[Tranche] )
                && 'Table'[Repayment Schedule Start Date]
                    <= EARLIER ( 'Table'[Repayment Schedule Start Date] )
        ),
        'Table'[Principal Amount (USD)] * 'Table'[Percentage]
    )

Measures:

Measure = 
SUM ( 'Table'[Principal Amount (USD)] )
    - SUMX (
        FILTER (
            ALLSELECTED('Table'),
            'Table'[Tranche] = MAX ( 'Table'[Tranche] )
                && 'Table'[Repayment Schedule Start Date]
                    <= MAX( 'Table'[Repayment Schedule Start Date] )
        ),
        'Table'[Principal Amount (USD)] * 'Table'[Percentage]
    )

Measure - ModifiedTotalValue = SUMX('Table',[Measure])
