Additional redo for supplemental logging at table level

I would like to know if anyone has done any testing on how much additional redo is generated if supplemental log groups are created on tables. I know that it will depend on the number of columns in a log group, column size, data type, etc., but I just want to get an idea about generally how much additional information (in terms of %age) is generated for DML statements.  

Any feedback will be appreciated.  

Thank you
