archive log size

Hi can someone please let me know what would be the impact on the volume of the archive log if the supplemental log group is created at the table level.

I am trying to run a CDC software for my oracle database which uses the logminer and i would need to enable the table level supplemental logging.
I am sure that enabling the supplemental logging at the table level would log more information into the archive logs than the usual logging.

I know that this depends on the number of columns, datatype and the type of transactions (insert/update/delete)

assuming the database has 100 user tables and has the equal number of insert/delete and updates happening to all the tables.

It would be great if some one can give the rough estimate of the archive log size growth.
