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 KS5 |
|---|---|---|
| $3,500 | Upfront cost (MSRP) | $12,000 |
| -$5.55 | Daily net profit | -$6.62 |
| -$5,527 | Net after 1 year | -$14,417 |
| -$7,554 | Net after 2 years | -$16,833 |
| -$9,581 | Net after 3 years | -$19,250 |
| 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.
