For this to work, you need a SERIAL ID column for the months in your calendar table.
A serial ID will start at 1, but will increase by 1 for each month, and NOT reset after 12.
For example, if your calendar starts in January 2016, then that month ID = 1. January 2017's month ID = 13.
Assuming that column exists in your calendar table, (and the column is called [MonthID]), this is the formula:
Measure = CALCULATE ( SUM ( TableName[ColumnName] ), FILTER ( ALL ( Calendar ), Calendar[MonthID] <= MAX ( Calendar[MonthID] ) && Calendar[MonthID] >= MAX ( Calendar[MonthID] ) - 11 ) )
