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 S17+ | Metric | Bitmain Antminer S9i (14Th) |
|---|---|---|
| — | Upfront cost (MSRP) | $65 |
| -$4.35 | Daily net profit | -$2.66 |
| -$1,589 | Net after 1 year | -$1,035 |
| -$3,177 | Net after 2 years | -$2,006 |
| -$4,766 | Net after 3 years | -$2,976 |
| — | 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.
