Bitcoin (BTC) Solo Mining Calculator
Calculate your odds of solo mining a Bitcoin block. Bitcoin uses SHA-256 proof-of-work with a current block reward of 3.125 BTC after the April 2024 halving. The network hashrate exceeds 800 EH/s, requiring dedicated ASIC miners like the Antminer S21 or Whatsminer M60.
How BTC Solo Mining Odds Work
Your chance of finding a block starts with your hashrate divided by the total network hashrate. This calculator then converts that expected block rate into an exact probability of finding at least one block over 1 day, 1 week, 1 month, or 1 year using a Poisson model. Solo mining BTC is still a lottery — improbable for individual miners, but someone wins every ~10 minutes. Already have a high share?
