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 S7-LN | Metric | Avalon A1246 |
|---|---|---|
| — | Upfront cost (MSRP) | $1,800 |
| -$1.58 | Daily net profit | -$5.02 |
| -$576 | Net after 1 year | -$3,632 |
| -$1,151 | Net after 2 years | -$5,465 |
| -$1,727 | Net after 3 years | -$7,297 |
| — | 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.
