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 S21+ Hyd | Metric | Canaan AvalonMiner Made A1366 |
|---|---|---|
| $2,499 | Upfront cost (MSRP) | $699 |
| $0.00 | Daily net profit | -$3.12 |
| -$2,499 | Net after 1 year | -$1,838 |
| -$2,498 | Net after 2 years | -$2,976 |
| -$2,498 | Net after 3 years | -$4,115 |
| Takes ~8,833.6 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.
