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 S23 | Metric | Bitmain Antminer S9 (12.5Th) |
|---|---|---|
| $4,999 | Upfront cost (MSRP) | $65 |
| $2.85 | Daily net profit | -$2.50 |
| -$3,960 | Net after 1 year | -$977 |
| -$2,922 | Net after 2 years | -$1,889 |
| -$1,883 | Net after 3 years | -$2,800 |
| Takes ~4.8 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.
