Calculate exact electricity costs for crypto mining. Enter wattage and rate per kWh to see hourly, daily, monthly, and annual power costs for your setup.
Electricity is the largest ongoing cost in cryptocurrency mining, often exceeding the cost of hardware over a miner's lifetime. This calculator helps you determine the exact electricity expense for your mining operation at any scale — from a single GPU to a warehouse full of ASICs.
Enter your equipment's power consumption in watts and your electricity rate per kilowatt-hour. The calculator shows your costs broken down by hour, day, month, and year, giving you a complete picture of your power expenses. You can also factor in time-of-use rates or curtailment hours.
Accurate cost tracking is essential for mining profitability. Even small measurement errors compound when equipment runs 24 hours a day, 365 days a year.
Crypto traders, long-term holders, and DeFi participants benefit from transparent crypto mining electricity cost calculations when planning entries, exits, or portfolio rebalances. Revisit this calculator whenever market conditions shift to keep your strategy grounded in accurate data.
Electricity costs determine whether mining is profitable. A profitable operation at $0.05/kWh can easily be unprofitable at $0.12/kWh. This calculator gives you precise figures for budgeting and helps you evaluate whether your electricity rate supports viable mining. Real-time recalculation lets you model different market scenarios quickly, so you can act with confidence rather than relying on rough mental estimates.
Hourly Cost = (Watts / 1000) × Rate Daily Cost = Hourly Cost × Hours/Day Monthly Cost = Daily Cost × 30 Annual Cost = Daily Cost × 365 Daily kWh = (Watts / 1000) × Hours/Day
Result: $6.24/day, $187.20/month, $2,277.60/year
A 3,250W mining rig running 24/7 at $0.08/kWh consumes 78 kWh daily. At $0.08 per kWh, that's $6.24/day, $187.20/month, or $2,277.60/year. This is the baseline cost your mining revenue must exceed for profitability.
For most mining operations, electricity represents 60-80% of total operating costs. Getting the best possible rate is just as important as choosing efficient hardware. Many large mining operations locate specifically to access cheap power.
Don't rely on software-reported power draw — measure at the wall with a reliable power meter. Software readings can be off by 10-20%. For accurate budgeting, measure your entire rig including PSU losses.
Explore all available rate structures: residential vs commercial, time-of-use, demand response programs, and interruptible service. Some utilities offer special rates for large loads. Industrial parks may have contracted rates that are much lower than residential.
A modern ASIC miner like the Antminer S21 uses about 3,500W (3.5 kW). Running 24/7, that's 84 kWh per day or about 2,520 kWh per month. At $0.10/kWh, that costs $252/month per miner.
Rates below $0.05/kWh are excellent for mining. $0.05-0.08/kWh is competitive. $0.08-0.12/kWh requires efficient equipment. Above $0.12/kWh makes most mining unprofitable except during crypto price surges.
Yes. Air conditioning or cooling fans add to your power bill. In data center terms, this is captured by PUE (Power Usage Effectiveness). A PUE of 1.2 means 20% overhead for cooling. Include this in your total wattage.
Solar panels can reduce or eliminate electricity costs but require significant upfront investment. A mining operation using 3 kW needs a ~5-6 kW solar array (accounting for night and cloudy periods plus battery storage). The ROI on solar + mining can be very attractive in sunny regions.
Strategies include: negotiating better rates with your utility, using off-peak time-of-use rates, deploying solar or wind power, choosing more efficient hardware, undervolting GPUs, and locating operations in regions with cheap power. Review your results periodically to ensure they still reflect current conditions.
Running at 240V vs 120V doesn't change watt consumption but slightly improves PSU efficiency (1-2% savings). More importantly, 240V allows more equipment per circuit and reduces copper losses in wiring.
