I am trying to create a formula that can calculate spend by month based on a campaign flight and total budget. Ideally, I would have a column for each month.
I've tried using a helper formula which worked in excel of =MAX(0,MIN($E2,EOMONTH(C$1,0))-MAX($D2,C$1)+1) to get the days in a month and then multiple daily spend by that amount, but Smartsheet doesn't have the EOMONTH function.
(E2 being end date, D2 being start date, and C1 being the start of the month)
