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.
| Innosilicon A4 Dominator | Metric | Innosilicon S11 SiaMaster |
|---|---|---|
| — | Upfront cost (MSRP) | $2,000 |
| -$2.52 | Daily net profit | -$3.09 |
| -$920 | Net after 1 year | -$3,126 |
| -$1,840 | Net after 2 years | -$4,252 |
| -$2,759 | Net after 3 years | -$5,378 |
| — | 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.
