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.
| Antminer AL1 | Metric | Antminer S9j |
|---|---|---|
| $10,000 | Upfront cost (MSRP) | — |
| -$7.50 | Daily net profit | -$2.73 |
| -$12,737 | Net after 1 year | -$995 |
| -$15,473 | Net after 2 years | -$1,991 |
| -$18,210 | Net after 3 years | -$2,986 |
| Does not pay back at current rates (negative daily profit) | Payback period | — |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
