Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| Canaan AvalonMiner 1066 | Metric | Canaan AvalonMiner 1166 Pro |
|---|---|---|
| $1,255 | Upfront cost (MSRP) | $404 |
| -$6.00 | Daily net profit | -$5.25 |
| -$3,446 | Net after 1 year | -$2,319 |
| -$5,636 | Net after 2 years | -$4,234 |
| -$7,827 | Net after 3 years | -$6,149 |
| Does not pay back at current rates (negative daily profit) | Payback period | Does not pay back at current rates (negative daily profit) |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
