Cost & ROI Over Time
A miner pays for itself in profit, not specs. These projections track upfront cost against one, two and three years of net earnings at $0.10/kWh.
| Avalon A1566 | Metric | Canaan AvalonMiner 1146 Pro |
|---|---|---|
| $5,500 | Upfront cost (MSRP) | $1,150 |
| -$1.48 | Daily net profit | -$5.57 |
| -$6,040 | Net after 1 year | -$3,183 |
| -$6,580 | Net after 2 years | -$5,217 |
| -$7,120 | Net after 3 years | -$7,250 |
| 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.
