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 S19k Pro |
|---|---|---|
| $3,000 | Upfront cost (MSRP) | $313 |
| -$3.69 | Daily net profit | -$2.25 |
| -$4,348 | Net after 1 year | -$1,136 |
| -$5,696 | Net after 2 years | -$1,958 |
| -$7,044 | Net after 3 years | -$2,781 |
| 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.
