Mining Electricity Cost Calculator

Power draw is the single biggest variable separating a profitable mining rig from one that bleeds cash, and this tool puts a precise dollar figure on that draw so you can judge whether an operation actually pays. As energy prices and network difficulty swing, that number moves with them. For reference, EIA's Electric Power Monthly put the U.S. average residential price at 18.34¢ per kWh in June 2026 and the industrial average at 9.17¢; the rate on your own bill is the one to enter.

The math behind the estimate is direct: multiply the device's power draw in watts by the hours it runs each day and divide by 1,000 to get daily kWh, then multiply by your electricity rate for the daily cost. The calculator shows that daily cost plus a 30-day month and a 365-day year. It does not estimate mining revenue, so to see profit, subtract this cost from your pool's payout estimate or use the mining profitability calculator.

Two traps catch most miners. The first is treating electricity rates as fixed when peak-hour tariffs and rate hikes can quietly erode margins, so build in some headroom. The second is ignoring cooling, which in warmer climates can add a meaningful share to total energy use. Difficulty and coin prices also move sharply and without warning, so any projection here is a snapshot worth revisiting often rather than a permanent forecast.
