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.
| Bitmain Antminer S23 | Metric | Avalon A1566 |
|---|---|---|
| $4,999 | Upfront cost (MSRP) | $5,500 |
| $3.05 | Daily net profit | -$1.55 |
| -$3,887 | Net after 1 year | -$6,067 |
| -$2,776 | Net after 2 years | -$6,633 |
| -$1,664 | Net after 3 years | -$7,200 |
| Takes ~4.5 years to pay back at current rates | 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.
