Cost of a 51% attack

Hardware cost only, at cheapest rate

That would consume kWh per day ($ per day)

The profits of an attack 51% are explained on the page How does Bitcoin works?. In this calculation, we make the assumption that the attacker is starting from scratch with no ability to get hardware or electricity cheaper than the current best offer. This is of course just a simple estimation, and those not take into account any of the other attack vectors.
