I know different lossy audio compression techniques use different codecs and this is not to determine which is better or worse.

Do you divide the bitrate by the number of channels to determine the loss (or compression) ?

Here are 3 generic codecs (names changed to protect the innocent):

Codec A; 5.1 max. bitrate 1.509 = 250 bits/channel ?

Codec B; 5.1 max. bitrate 448 = 75 bits/channel ?

Codec C; 2.0 max. bitrate 160 = 80 bits/channel ?

codec C is normally 180kbps
BTW your breakdown is irrelevant as both codecs use "bitpooling".

Yes Bitpooling! which means that encoder can allocate bits "where need it most" Codec "b" does this more often.
The compression rate is fairly known to many,but there is another term that drive one these formats: efficiency.
