No you really can't because the biggest share of costs is the mining gear and it has been very difficult if not impossible for anyone to buy such gear at prices that don't lose money. The reason of course is that ASIC developers themselves mine in large farms and their costs are totally opaque (and likely quite different from one another). The way the competitive mining market works is the least efficient miners break even or lose money. That's basically everyone in the public. How much everyone else (ie ASIC developers) make only they know.
