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 S9i (13Th) | Metric | Bitmain Antminer S9i (14Th) |
|---|---|---|
| $65 | Upfront cost (MSRP) | $65 |
| -$2.60 | Daily net profit | -$2.66 |
| -$1,016 | Net after 1 year | -$1,037 |
| -$1,966 | Net after 2 years | -$2,010 |
| -$2,917 | Net after 3 years | -$2,982 |
| 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.
