If your starting date is in A1, use =A1+10 and =A1+30.

If you want the resulting dates to stay blank until A1 is filled in, then
=IF(A1="","",A1+10), and similarly for A1+30.

I have several dates that I need to track for one line item. They are
basically on a time line. I send a letter out and 10 days later I need to
call. Then 30 days later I need to mail a report. I need to know how
create
a formula that will automatically fill in the due dates when I enter the
starting date.
