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 A1246 | Metric | Avalon A1446 |
|---|---|---|
| $1,800 | Upfront cost (MSRP) | $3,200 |
| -$5.27 | Daily net profit | -$3.54 |
| -$3,724 | Net after 1 year | -$4,492 |
| -$5,648 | Net after 2 years | -$5,784 |
| -$7,572 | Net after 3 years | -$7,075 |
| 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.
