OreCrusher can be used to work out the profit for your server (along with other addons including Trade Skills Master and Auctioneer), which you can download from Curse. They will work out based on scanning the auction house at the time giving you the most accurate answers.
It's completely flexible as it's 100% dependant on your server prices. On my server elementium needs to be under 25g a stack and pyrite 60g at the moment, but if gem prices go up or down (or enchanting mat prices) so do those values.
