Mining Electricity Cost Calculator

Electricity is usually the single largest recurring expense in mining, and the number on a miner's spec sheet is never the whole story — this calculator accounts for that by adding a cooling overhead percentage on top of raw rig wattage before doing any cost math. That overhead models the extra energy spent on fans, air conditioning, or ventilation needed to keep hardware from thermal-throttling, following the same logic as a data center's PUE (Power Usage Effectiveness) metric; a typical range is 10-20% depending on your setup and climate, and it's applied per rig before multiplying by the number of rigs you run. From that adjusted total power draw, the calculator computes energy consumption in kWh across a day, a 30-day month, and a full year, factoring in how many hours per day the rigs actually run (most operations run 24/7, but the hours-per-day input lets you model partial-uptime or demand-response scenarios).

Multiplying consumption by your electricity rate produces daily, monthly, and annual cost figures, plus a per-rig monthly cost that's useful for comparing against a single unit's expected mining revenue to judge profitability. A common oversight when using a tool like this is forgetting that cooling overhead isn't optional or fixed — it varies significantly with ambient temperature, ventilation quality, and mining density, so a figure that's accurate in a well-ventilated garage in winter can understate real costs in a cramped, poorly cooled space in summer.
