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 S19k Pro | Metric | Canaan AvalonMiner 1166 Pro |
|---|---|---|
| $2,800 | Upfront cost (MSRP) | $404 |
| -$2.13 | Daily net profit | -$5.13 |
| -$3,578 | Net after 1 year | -$2,276 |
| -$4,356 | Net after 2 years | -$4,147 |
| -$5,135 | Net after 3 years | -$6,019 |
| Does not pay back at current rates (negative daily profit) | 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.
