A bit of napkin math. Google tells me that the Hershey chocolate bar is 43g (1.55 oz) and is 11% cocoa.
Though I think your line of reasoning is probably valid...cocoa is expensive, but not the biggest part of the cost of a bar...did you remember the cocoa butter? Very expensive stuff.
If a 43 gram bar is 21 grams of added sugar, that's 22 grams of "other", which is mostly condensed skimmed milk, cocoa, and cocoa butter, with (in this case) some dairy butter. The other ingredients are negligible by weight. So I guess you have to guess how much condensed milk there is--subtract that from 22 and you probably won't be far off from the total cocoa mass weight (powder+cocoa butter combined).
