[Star Wars] How much did Clone Troopers and Battle droids cost?

Since both forces are essentially "manufactured", you could  hypothetically calculate each battle as good or bad in the long run  based on credit to kill ratios; so if that's the case how many droids  does each clone have to destroy to have a positive dollar to donut ratio? How many credits does it take to grow a clone, equip him, and get him on the battle field? how much to manufacture a droid and his blaster?

Given how prevalent droids were in the Star Wars universe it's a pretty good bet an army of them was far cheaper to mass produce than an army of grown/fed/trained/equipped clones. Even with rapid aging would still take years to manufacture them in large enough numbers. 

Droids would be great for planets with toxic atmospheres, significantly higher gravity or when you want to drop 20 million killing machines around a major metropolitan city for an extended period of time. Clones would be far better suited for special operations, spying and intelligence gathering behind enemy lines.
