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 S19 | Metric | Antminer S9 |
|---|---|---|
| $2,000 | Upfront cost (MSRP) | — |
| -$4.38 | Daily net profit | -$2.74 |
| -$3,598 | Net after 1 year | -$999 |
| -$5,197 | Net after 2 years | -$1,997 |
| -$6,795 | Net after 3 years | -$2,996 |
| Does not pay back at current rates (negative daily profit) | Payback period | — |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
