Enter your miner’s hash rate and power use, your electricity price and the network figures to estimate your mining profit.
Bitcoin miners compete to find blocks, and each block pays a reward. Your share of the network is your hash rate divided by the total hash rate, which is set by the difficulty. The calculator uses the standard formula: the coins you expect per day equal your hashes per second, times the seconds in a day, times the block reward, divided by the difficulty times 2 to the power 32. A pool takes a fee from that income.
The main running cost is electricity. The power your miner draws, in kilowatts, multiplied by 24 hours and your price per kilowatt-hour, gives the daily cost. Profit is the income, converted to dollars at the coin price you enter, minus the electricity cost. The calculator also shows the payback time on the hardware, if the profit is positive.
Mining profit is not steady. The difficulty usually rises as more miners join, which lowers your coins per day. The block reward halves about every four years. The coin price can double or halve in months. A miner that is profitable today can lose money next month, so treat the result as a snapshot, and check the current difficulty and price from a block explorer or a mining stats site before you decide to buy.
Work out the coins you expect each day from your hash rate and the network difficulty, convert them to dollars, and subtract the daily cost of electricity.
It is a number that sets how hard it is to find a block. It adjusts about every two weeks to keep blocks coming roughly every ten minutes.
The lower the better. Many miners need under about 0.07 dollars per kWh to profit, though it depends on the hardware and the coin price.
It uses the Bitcoin proof-of-work formula, so it fits Bitcoin and coins that use the same hashing scheme with a comparable difficulty scale. It is not meant for other mining methods.
Mining pools combine many miners and take a small percentage of the rewards, often between 0% and 3%.
