Hashrate Efficiency Calculator

Benchmark mining rigs by calculating how many megahashes per watt they deliver—essential for tuning profitability and thermal budgets.

Enter the sustained hashrate in megahashes per second reported by your rig or pool dashboard.
Use the wall-plug wattage, ideally measured with a power meter for accuracy.

Outputs assume steady-state operation. Validate against hardware specifications, ambient conditions, and regional electricity pricing before making investment decisions.

Examples

  • 62,000 MH/s Ethereum ASIC at 1,290 W ⇒ 48.06 MH/s per W
  • 950 MH/s GPU stack at 480 W ⇒ 1.98 MH/s per W after undervolting
  • 140 MH/s test rig at 65 W ⇒ 2.15 MH/s per W with aggressive airflow

FAQ

Should I average hashrate over time?

Yes. Use a 24-hour average or pool-reported effective rate to smooth out share variance and stale submissions.

How do GH/s or TH/s units fit in?

Convert to MH/s by multiplying GH/s by 1,000 or TH/s by 1,000,000 before entering the value.

Does PSU efficiency matter?

Absolutely. Measure power at the outlet so conversion losses inside the power supply are included in the wattage.

Can I compare rigs mining different algorithms?

The math works, but profitability depends on coin price and difficulty. Use this metric together with revenue estimates per hash.

Additional Information

  • Efficiency = Hashrate ÷ Power draw. Higher values indicate more hashes per unit of electricity consumed.
  • Compare rigs on the same algorithm only—switching coins or hash functions changes the hashrate baseline.
  • Track real electricity tariffs and cooling overheads separately to derive full cost per megahash.
