Profit per Watt is the net daily profit a miner generates for each watt of power it draws: (Revenue − Power Cost) ÷ Watts.
Why it matters
Two miners can produce the same daily profit, but the one that does it with fewer watts is more resilient when electricity prices rise or coin prices fall. That efficiency is exactly what Profit per Watt captures.
How CoinWarz calculates it
We combine live network difficulty, block reward, coin price, and your electricity rate to compute revenue, subtract power cost, and divide by the hardware's rated wattage.
