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.
| Antminer AL1 | Metric | Bitmain Antminer S21+ Hyd |
|---|---|---|
| $10,000 | Upfront cost (MSRP) | $2,499 |
| -$7.49 | Daily net profit | $0.00 |
| -$12,733 | Net after 1 year | -$2,498 |
| -$15,466 | Net after 2 years | -$2,498 |
| -$18,199 | Net after 3 years | -$2,497 |
| Does not pay back at current rates (negative daily profit) | Payback period | Takes ~4,134.8 years to pay back at current rates |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
