These rows illustrate typical operating assumptions. Replace them with your miner specifications, tariff, and site conditions for a tailored estimate.

Formula Used

The calculator supports two input paths. In efficiency mode, miner power comes from hashrate multiplied by efficiency. In direct mode, you enter power directly.

1. Device watts per miner = Hashrate in TH/s × Efficiency in J/TH

2. Wall watts per miner = Device watts ÷ PSU efficiency

3. Facility watts per miner = Wall watts × PUE

4. Fleet nameplate watts = Facility watts per miner × Number of miners

5. Average fleet watts = Fleet nameplate watts × Uptime percentage

6. Energy per hour = Average fleet watts ÷ 1000

7. Energy per day = Energy per hour × Scheduled hours per day

8. Cost = Energy × Electricity rate

9. Emissions = Energy × Carbon intensity

PUE adds facility overhead such as cooling, fans, networking, and infrastructure losses. PSU efficiency adjusts device draw to the expected wall draw.

Frequently Asked Questions

1. What does J/TH mean?

J/TH means joules per terahash. It shows how much energy a miner needs to process one terahash of work. Lower values usually mean better energy efficiency.

2. Why does PUE matter?

PUE captures facility overhead beyond the miner itself. Cooling, ventilation, power distribution, and support systems raise true site consumption above the machine’s listed wattage.

3. Should I use uptime and hours per day together?

Yes. Hours per day represents scheduled run time. Uptime reflects real availability inside that schedule, including restarts, maintenance, thermal throttling, and power interruptions.

4. What if I only know miner wattage?

Use direct power mode. Enter the known wattage, then add miner count, facility assumptions, and electricity price to estimate hourly, daily, monthly, and yearly energy use.

5. Why is wall power higher than device power?

Wall power includes power supply losses. If a PSU is not perfectly efficient, the socket must provide more energy than the miner electronics actually receive.

6. Can this calculator estimate carbon impact?

Yes. Enter a carbon intensity value in kilograms per kilowatt-hour. The calculator multiplies energy use by that factor to estimate daily, monthly, and annual emissions.

7. Is the monthly total fixed at 30 days?

No. You can set any days-per-month value. Many users use 30.44 for yearly averaging, while others use a billing-cycle length such as 28, 30, or 31.

8. Does higher hashrate always mean higher power?

Not always. Power depends on both hashrate and efficiency. A faster miner can sometimes use similar or even lower energy per terahash than an older model.
