Grand Total substract with previous record count

Thank you for the data.

You can create a measure using the following formula.

It will be best if you create a calculated column by summing up all the columns in every row. to get total roll up amount

Total =
VAR totalvalue =
CALCULATE ( SUM ( 'Table'[RollUp] ), REMOVEFILTERS ( 'Table' ) )
VAR monthvalue =
CALCULATE ( SUM ( 'Table'[RollUp] ) )
VAR Total =
IF ( ISBLANK ( monthvalue ), BLANK (), totalvalue )
VAR CurrentDate =
MAX ( 'Table'[Month] )
VAR rollupYTD =
CALCULATE (
SUM ( 'Table'[RollUp] ),
FILTER ( ALL ( 'Table' ), 'Table'[Month] < CurrentDate )
)
VAR result = Total - rollupYTD
RETURN
result

 You can get result as follows

 Thanks,
