Hi, I'm trying to create a user-friendly Excel sheet to aid my
colleagues in visualizing the fiscal year impacts of new contracts
with our vendors. The contracts are always written on a calendar year
basis (i.e., "the vendor will receive a sum total of $X, payable in
equal quarterly installments, during calendar year 2010") but of
course internally we need to translate that in terms of our fiscal
year (May 1-April 30). I'd like to have a worksheet that would allow
the user to input different scenarios to see their effects on
different FYs. For example, what is the expected impact on each of the
next 3 FYs if I pay this vendor monthly versus paying semi-annually
versus paying quarterly?

I'm having a hard time figuring out where to start on this without
relying on some monstrously large IF statements. Would welcome any
tips or ideas anyone has. The end product really needs to be quite
simple -- ideally the user would just input the contract date range
and annual amount due, and then can choose among different scenarios
to see what happens -- but I'm game to set up sophisticated macros or
analyses in the background if necessary.

Thanks in advance for your help!
