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
    )
)
