See if this example is gets you pointed in the right direction:

A1: DueDate
B1: InvAmt
C1: 30_Days
D1: 60_Days
E1: 90_Days
F1: Over_90

A2: (some date)
B2: (an invoice amount)
C2: =IF(TRUNC(($A2-TODAY())/30)=0,$B2,"")
D2: =IF(TRUNC(($A2-TODAY())/30)=1,$B2,"")
E2: =IF(TRUNC(($A2-TODAY())/30)=2,$B2,"")
F2: =IF(TRUNC(($A2-TODAY())/30)=3,$B2,"")

(copy the formulas in C2 thru F2 down as far as you need)

Does that help?

Hi,
I'm trying to create an Accounts Receivable "aging report", using Excel
2003. I've got a field (a date field), that provides the date of invoice.
I'd like then to add 30, 60, or 90 days from that date, and call that the
"Due Date" for payment in another column.

Thanks,
Peter
