I need a formula to calculate the end date of a monthly term when the start
date is not the 1st of the month. This is to show the proration for the
first month only, so the end date should be the last day of the initital
month/yr. Then when showing the rates for each period, all subsequent
periods would start on the 1st of the month. For example, start date
8/16/06, initial end date needs to be 8/31/06. The current forumla I am
using is:
=IF(G870,(EDATE(C87,G87)+(32-DAY(EDATE(C87,G87)-DAY(EDATE(A1,G87))+32))*MOD(G87,1)-1),"")
This works for all situations EXCEPT when the start date is other than the
1st and the term is less than 1 mo. (decimal).

Any clues???
