Range of cost of mining ONE BTC ?

[qwerty555]

 Could members offer an estimate of the average cost of mining ONE BTC at current difficulty.


Please include
1 estimate of power used (In $ in ur location and kwh as power costs vary from country to country)

2  cost of rig and maintenance/ repair ( maybe use 5 yrs to depreciate it 100%)

3  any other running costs  

This does not have to be exact..I am looking for a ball park figure and large variations.

Thanks

Ps If your busy I  will do the Math if you have figures for larger numbers of BTC mined

Mate, by the time you typed it in you could have googled a calculator, AND do the math yourself, customized... :/

First you need to know how much MHash you need.

then you need to know the equipment you'll use to get the BTC you want in the time frame you want.
