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.
| Antminer S19j | Metric | Antminer Slim Edition (S9) |
|---|---|---|
| $2,000 | Upfront cost (MSRP) | $350 |
| -$4.20 | Daily net profit | -$2.21 |
| -$3,533 | Net after 1 year | -$1,156 |
| -$5,066 | Net after 2 years | -$1,962 |
| -$6,599 | Net after 3 years | -$2,768 |
| 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.
