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 A1366 | Metric | Avalon A1566 |
|---|---|---|
| $3,500 | Upfront cost (MSRP) | $5,500 |
| -$3.12 | Daily net profit | -$1.55 |
| -$4,639 | Net after 1 year | -$6,065 |
| -$5,777 | Net after 2 years | -$6,630 |
| -$6,916 | Net after 3 years | -$7,194 |
| 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.
