Thanks for replies everyone but I'm still wanting figure this out.

So as an example, I want to find out how much it will cost to mine 1 Denarius coin in BTC.

Tribus hashing power is 0.00000500btc per mh/day

Block reward is 3 dnr

block time is 30 seconds

network GH/s is 1032.1434

If anyone can help me find out what it will cost to mine 1dnr using the above data that would be really helpful.
