That really is a "how long is a piece of string" question.
It all depends on your data type
If you have a lot of encrypted of hig density multi media files then you may not get much in the way of de-dupe rates.
If your backups are the run of the usual run of the mill users docuements, SQL and Exchange databases etc. then i have seen 99 and 100% on the second run
If you do a lot of SQL logs backups then enable de-dupe compression to get any de-dupe on those at all
There are de-dupe assesment tools available so you may want to ask your Symantec partner for some advice or consultancy to do some testing for you
Hope this helps
