Excel Formula Help with Calculating Dates
I have a column in a work sheet that has a Subscription Start Date, depending on that date depends on what is billed. Here is what I am wanting, I have tried different ways of writing this out and I...
=B1*IF(YEAR(A1)<YEAR(TODAY()),1,IF(A1>=DATE(YEAR(TODAY()),7,1),0,(7-MONTH(A1)))/12)
or, equivalently
=B1*IF(A1<DATE(YEAR(TODAY()),1,1),1,IF(A1<DATE(YEAR(TODAY()),7,1),(7-MONTH(A1))/12,0))
That worked for Jan Billing Column, So would July Billing (7/1-12/31) look like this:
=B1*IF(Year(A1)<Year(TODAY()),1)/12), if(A1>Date(Year(Today())),8,1)/12),0,(13-Month(A1))))/12)
=B1*IF(Year(A1)<Year(TODAY()),1)/12), if(A1>Date(Year(Today())),8,1)/12),0,(13-Month(A1))))/12)
Please explain the rules for July billing in detail.
- For July Billing:
If current year>start date year then July Billing = Annual Fee/2
IF Current year <start date year then July billing = 0
If current year = start date year then,we look at the month of startdate,if month is <7,then July Billing =Annual Fee/2, else july billing = (Annual Fee/12)*(13-month(startdate)
