Mining Power & Electricity Cost Calculator

Quick math for hobby miners: convert hashrate + efficiency (J/TH) into watts, kWh/day, and cost per day / month / year. Optional: basic Ohm’s law calculator.

Power: W = TH/s × (J/TH) Energy: kWh/day = (W ÷ 1000) × 24 Cost: $/day = kWh/day × $/kWh

Inputs

Enter your hashrate.
We convert everything to TH/s.
Lower is better. Example: 20 J/TH.
Example: $0.22/kWh.
Notes:
  • Efficiency is a *device* number — use your real measured J/TH if you have it.
  • This does not include PSUs that are wildly off spec or power-factor weirdness.

Electrical calculations (optional)

Typical US: 120V (or 240V).
Amps.
Ohms.

Tip: In the Ohm’s law section, fill in any two fields and we’ll solve the third.

Sanity check: If you know your measured watts at the wall, you can back-calc J/TH:
J/TH ≈ Watts ÷ TH/s
