What Is the ASIC Efficiency Index?
The ASIC Efficiency Index measures the marginal electricity cost to mine 1 BTC using the most energy-efficient ASIC hardware commercially available — across three electricity tariff categories: industrial, commercial, and residential. It gives miners and analysts a real-time cost floor benchmark, updated daily as network difficulty and ASIC generations evolve.
Industrial
Wholesale power rates
Large-scale miners with long-term power agreements. Lowest cost tier.
Commercial
Standard business rates
Small to mid-scale mining operations paying commercial electricity tariffs.
Residential
Retail household rates
At-home miners paying retail electricity prices. Highest cost tier.
Step changes in the index typically reflect new ASIC generation releases — not just shifts in network difficulty or BTC price. The metric shows a marginal lower bound: actual all-in breakeven costs (hardware, cooling, hosting) are higher.
