Enter your own $/kWh. "Heater mode": if you would heat the room anyway, electricity counts as $0.

📐 HOW IT IS CALCULATED

Block-findingexpected time to a block = difficulty × 2³² ÷ your hashrate — independent of block time, uses live difficulty from our nodes
Net rewardBTC/BCH/BC2/BCH2 block reward × 0.99 (1% fee) · XEC = 3,125,000 × 58% solver share × 0.99 (1% fee)
Electricity(watts ÷ 1000) × 24 × 30 × $/kWh — or $0 in heater mode
Breakeventhe $/kWh at which expected reward = electricity cost (net = 0)
Modeexpected time ≤ 30 days → expected return · longer → lottery (jackpot + odds)
Variancesolo is a Poisson process — expected values, not a schedule. Same expected value as pool, but paid as rare blocks instead of smooth income
