T-SQL: Formula for Computing "Month 1", "Month 2", etc.

Hello:

I have a purchase order table that has a field called Document Date (POP10100.DOCDATE).

I need a formula that will compute "Month 1" for any such dates that are in the current month; "Month 2" for any such dates that are next month; "Month 3" for and such dates that are two months later; all the way through 18 months from now.

I have tried all variations of the T-SQL DATEPART, DATEDIFF, GETDATE, but the more I study T-SQL, the less I learn.  I just can't "get it".

Please help!

Thanks!
