Today I have mined 100 cgb in a 24 hour period and have been burning 7.5kwh - 8kwh on average. My electricity cost here in the UK is 11.5 pence per kwh (and that is one of the cheapest tariffs) so that is £22.08 per 24 hours. The cgb I have mined are only worth around £18!!!
The electricity is everything used including switches, router, extractor and inlet fans.
I find the coinwarz calculator to be over optimistic for the number of coins mined as well.
Is anyone actually making any money?
Coinwarz is slow on updates and/or inaccurate at times with the profits. Also, they don't have other coins that are more profitable to mine on there. To be honest, mining has some many variables to account for: equipment costs, electricity usage/cost per kwhr, a coin's exchange rate, difficulty mining the coin, etc..... I'm have second thoughts of backing out of mining and just buying coins outright and selling at the right time, just like the stock market....Electricity companies are making a killing off of miners....Last month, after electricity cost, I made $70 USD with my 3 GPU card setup.....Just put it like this, not something enough to make a living off of yet....Only those who were fortunate to mine the first 3 years of Bitcoin and 1st year of Litecoin, made the most profits....
