Looking for a very simple calculator showing average mining cost per BTC

This is the best one because it takes into account change in difficulty going forward...

very nice thanks for this link I was looking something like this for long time cheers for you

I've seen people in the past claiming, for example, that it cost an average of $80 to mine a bitcoin (this was before ASICs took over).

Such a figure would be useless. The cost to mine 1 bitcoin varies greatly depending on the hardware you are using, whether or not the hardware is overclocked/underclocked, the current network difficulty and your electricity cost. The cost to mine 1 Bitcoin on a 10 year old single-core processor processor could be in the $100,000 to $1,000,000, while the cost of mining 1 Bitcoin on an ASIC could be <$5, or even "free" if you do not take into account hardware depreciation and don't pay electricity costs.

I am looking for a simple site that just gives me such a flat average cost to mine a single bitcoin based on current difficulty, average running costs (perhaps per country?) and a crude amortisation of hardware costs. Does such a thing exist?

Best thing to do is use the previosuly mentioned website, http://www.bitcoinx.com/profit/

Just fill in the hash rate of the device you are using to mine and enter your electricity cost.

Then use the figures to do the following to calculate the cost of mining 1 Bitcoin:

(1 / Coins per 24h at these conditions) * Power cost per 24h

This doesn't account for depreciation of hardware however.

That's a great calculator, thank you, although its still slightly more data than I'm looking for - I really do just want a crude, finger in the air estimate of $x to mine 1 bitcoin! Smiley

Tim, you won't get much simpler than this, the important variables are pre-entered for you, and it's pre loaded with the BFL 50Gh/s Miner.

You change..

1. How many G/hs the device you intend to buy produces
2. Change how much it costs you to buy

and it will figure out if it is profitable.

They do not consider difficulty increasing. I recommend you this one http://mining.thegenesisblock.com/

Yes they do, it's the line called "Profitability decline per year: 0.61"

0.61 decline per year??? Really? You'll get this decline in month or earlier. So I think http://mining.thegenesisblock.com/ is more realistic calculator.
