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 S19j | Metric | NerdNOS |
|---|---|---|
| $2,000 | Upfront cost (MSRP) | $59 |
| -$4.17 | Daily net profit | -$0.01 |
| -$3,520 | Net after 1 year | -$63 |
| -$5,041 | Net after 2 years | -$67 |
| -$6,561 | Net after 3 years | -$71 |
| 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.
