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.
| Avalon A1446 | Metric | Avalon A1566 |
|---|---|---|
| $3,200 | Upfront cost (MSRP) | $5,500 |
| -$3.09 | Daily net profit | -$1.55 |
| -$4,326 | Net after 1 year | -$6,066 |
| -$5,452 | Net after 2 years | -$6,631 |
| -$6,578 | Net after 3 years | -$7,197 |
| 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.
