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.
| Bitmain Antminer S23e U2H | Metric | Avalon A1246 |
|---|---|---|
| $19,600 | Upfront cost (MSRP) | $1,800 |
| $10.71 | Daily net profit | -$4.93 |
| -$15,690 | Net after 1 year | -$3,601 |
| -$11,780 | Net after 2 years | -$5,401 |
| -$7,869 | Net after 3 years | -$7,202 |
| Takes ~5.0 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.
