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 S9 (11.5Th) | Metric | Bitmain Antminer T9+ (10.5Th) |
|---|---|---|
| $65 | Upfront cost (MSRP) | $955 |
| -$2.29 | Daily net profit | -$3.05 |
| -$900 | Net after 1 year | -$2,070 |
| -$1,734 | Net after 2 years | -$3,185 |
| -$2,569 | Net after 3 years | -$4,300 |
| 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.
