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 Pro | Metric | Bitmain Antminer S21 (200Th) |
|---|---|---|
| $2,500 | Upfront cost (MSRP) | $1,076 |
| -$3.79 | Daily net profit | -$1.24 |
| -$3,885 | Net after 1 year | -$1,527 |
| -$5,269 | Net after 2 years | -$1,978 |
| -$6,654 | Net after 3 years | -$2,429 |
| 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.
