My workbook has columns from Y:CD with datesIncluded in the rows beneath this is customer revenue dataContract end date is in S2 promotion start date is in t2 and promotion end date is in u2 cease date is in v2Monthly sales price is in w2I need a formula which will accrue the income cumulatively each month between the promotion start and end date and then in the columns once the promotion end date is reached, reduce the accumulated balance equally each month until the contract end date. If the column dates are outside of the promotion start date and contract end date it should return 0.This date has a range of start and end dates with customers on different lengths of promotions
I currently am using this formula=IF(AM$5>=$T6,IF(AM$5<=$U6,IF(AM$5>$S6,0,(-$Z6*(DATEDIF($T6,AM$5,"m")+1))),IF(AM$5>$S6,0,($Z6*(DATEDIF($T6,$U6,"m")+1))/(DATEDIF($U6,$S6,"m")))),0)however instead of row 6 showing -28.45, -56.90, -85.35, 5.42, 5.42 etc I need it to show calculation asNEW with the unwind ending when the calculation reaches 0 at the contract end date
