it's 1.5x the laurel cost of elixir at the same level.
lvl 2 bravery = 1.5x lvl 124 elixir and so on
bravery is known to be 1%, which would be 15% boost at 150 (pretty big deal, think about the affect of lvl 3 inspire in pvp, granted you don't have the defense bonus). Also the 15% isn't a 15% boost in damage, similar to prestige battle bonus, it is an additional 15% boost on total spirit hit power, etc.
Depending on arms/enchants the actual increase in damage output will be in the 40-50% range.
The 0.5% for given for elixir and bravery are in terms of the damage calculator algorithm. True number for affect of elixir on defense rating is unknown, although 0.5% can be a good estimate.
