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.
| Bitmain Antminer S21 XP Hyd | Metric | Canaan AvalonMiner 1166 Pro |
|---|---|---|
| $5,099 | Upfront cost (MSRP) | $404 |
| $4.08 | Daily net profit | -$5.13 |
| -$3,609 | Net after 1 year | -$2,276 |
| -$2,118 | Net after 2 years | -$4,147 |
| -$628 | Net after 3 years | -$6,019 |
| Takes ~3.4 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.
