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 K7 | Metric | Antminer S17+ |
|---|---|---|
| $3,500 | Upfront cost (MSRP) | — |
| -$5.59 | Daily net profit | -$4.94 |
| -$5,540 | Net after 1 year | -$1,802 |
| -$7,580 | Net after 2 years | -$3,603 |
| -$9,621 | Net after 3 years | -$5,405 |
| 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.
