SQL formula needed for a MRR saved search

I am attempting to create an MRR saved search that will break out the monthly recurring revenue for an opportunity based on term. I have it mostly built but I am having difficulty getting anything with a term of less than 12 months to start, end, and divide into the proper months at the proper monthly rate. Here is an example:

Customer purchases an item for a total of $6000 that will have revenue recognized over 6 months starting in June and ending November 30th. I want monthly columns for all of 2014 (Jan, Feb, Mar...etc...) that will show $1000 in June, $1000 in July $1000 in August and so on through November. If I have a customer purchase an item with a 3 month term for $4000 I want it to break the $4000 over three months and to show that revenue in the appropriate month.
