You could be use measure instead of calculated column. I believe measure is best option to summarize the expression and also good to performance. you will use below expression as seen in the snapshot.

Hi @Anonymous ,

Thank you for @Syndicate_Admin answer , and I have other suggestions:

Below is my table:

The following DAX might work for you:

Column = 
 VAR _month = MIN('Table'[Year])
 VAR _new_month = MONTH(EDATE(_month,1))
 VAR _a = CALCULATE(MAX('Table'[FIFO]),FILTER('Table',MONTH('Table'[Year]) = _new_month))
 VAR _b = CALCULATE(MAX('Table'[FIFO]),FILTER('Table',MONTH('Table'[Year]) = MONTH(_month)))
 RETURN
 _b - _a

The final output is shown in the following figure:

RETURN
  'Table'[Value] - _a

The final output is shown in the following figure:
