Hi @yodha ,

You can follow these steps to try:

1. I have created a calculated column to fomat date column for easy calculation:

``Month-Year = VALUE(FORMAT('Table'[Date],"yyyymm"))​``

2. I have created a measure to calculate present cost to replace previous column because I thought it was contradictory when calculating total cost basd on previous month:

``````Present cost measure =
VAR _minmonthyear =
CALCULATE ( MIN ( 'Table'[Month-Year] ), ALLSELECTED ( 'Table' ) )
VAR _cmonthyear =
SELECTEDVALUE ( 'Table'[Month-Year] )
VAR _lastmonthyear =
CALCULATE (
MAX ( 'Table'[Month-Year] ),
FILTER ( ALLSELECTED ( 'Table' ), 'Table'[Month-Year] < _cmonthyear )
)
RETURN
IF (
_cmonthyear = _minmonthyear,
SUM ( 'Table'[Present cost] ),
CALCULATE (
SUM ( 'Table'[Present cost] ),
FILTER (
ALLEXCEPT ( 'Table', 'Table'[Categoary] ),
'Table'[Month-Year] = _minmonthyear
)
)
- CALCULATE (
SUM ( 'Table'[Forecast cost] ),
FILTER (
ALLEXCEPT ( 'Table', 'Table'[Categoary] ),
'Table'[Month-Year] < _cmonthyear
)
)
)
​``````

3. Finally, create a measure to calculate total cost:

``Total cost = [Present cost measure]-SUM('Table'[Forecast cost])​``

4. You will get the result like this:
