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.

Miner A Less efficient
Net profit $6.00 / day
Power draw
3,000 W
Profit per Watt $0.002000/W·day
Relative efficiency 50%
Miner B Efficient
Net profit $6.00 / day
Power draw
1,500 W
Profit per Watt $0.004000/W·day
Relative efficiency 100%
2× Profit per Watt

Same daily profit, half the power. Miner B lets you run twice the hashrate on the same circuit - that's why CoinWarz ranks by Profit per Watt instead of raw hashrate or sticker profit.

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.
