Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| Antminer K7 | Metric | Antminer S19 Pro+ |
|---|---|---|
| $3,500 | Upfront cost (MSRP) | $3,000 |
| -$5.55 | Daily net profit | -$4.58 |
| -$5,525 | Net after 1 year | -$4,671 |
| -$7,549 | Net after 2 years | -$6,342 |
| -$9,574 | Net after 3 years | -$8,012 |
| 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.
