I need a formula that will calucalte the monthly total based on the following conditions:
Col A = Yearly Cost
Col B = The number of the month when the costs are starting (1=Jan etc)
Col C = The duration or the number of months for which the costs are to spread
Col D is Year 2013 with the months across columns D-O. Row 1 above those columns shows the month's corresponding number.
Right now I have =IF($B3<=D$1,$A3/$C3,0) however if my start month is 1 and my duration is 5, I need the costs to stop after May. I've attached a sample file. Thanks for the help.Calculate based on start month and duration.xlsx
