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 KS3 | Metric | Antminer S19j Pro+ |
|---|---|---|
| $8,000 | Upfront cost (MSRP) | $3,200 |
| -$8.13 | Daily net profit | -$4.65 |
| -$10,966 | Net after 1 year | -$4,896 |
| -$13,932 | Net after 2 years | -$6,592 |
| -$16,898 | Net after 3 years | -$8,288 |
| 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.
