Cost of mining hardware USD Profitability decline per year Nothing guaranteed, of course this is only a rough estimate! Do not enter commas, only dots for decimal separator. Default values are for a system of four s.
Why Our Calculator is the Most Accurate
Estimate Strategy Extrapolating bitcoin difficulty or price is pure voodoo. It is much easier to predict the relationship of the two parameters in form of the Mining Factor.
If it falls people will stop mining eventually. The estimate starts with the current Mining Factor and decreases it exponentially such that the decrease accounts for the factor decline per year.
Things to consider that might eat into your profit: The values above are only a snapshot. The network and markets are moving quickly. Check out these diagrams to get a feeling for it. Looks like if your mining operation is not profitable now, it probably will not be in the future. With rising bitcoin exchange rates it might be more profitable to buy bitcoins than to mine.
There are spreadsheets available in this thread or this one with some FPGA data for a more custom calculation. The calculation is based on average block generation time.
The closer the average generation time is to the time frame the more the resulting revenue depends on luck. Unless you want to do pool hopping you should go to a pool with hopping protection.
Instructions on how to use the Bitcoin Mining Calculator:
I recommend Arsbitcoin and EclipseMC with namecoin merged mining. P2Pool is a new completely decentralized alternative. The Bitcoin block mining reward halves everyblocks, the coin reward will decrease from 25 to This might partly be compensated by falling difficulty, raising prices, higher transfer fees, etc. A mining computer generates a lot of heat as a byproduct. Other byproducts could be noise and an angry wife. Do you have lots of experience with and like working with computers during lonesome nights?
You have to spend quite some time to set up the system easily several days! You will probably not be able to reach the highest values in the Mining Hardware Comparison. Results in the list above do not reflect the number of cards.
