Cost & ROI Over Time
Sticker price versus what the miner actually earns back: the table below projects cumulative net profit at a $0.10/kWh electricity rate.
| Antminer K7 | Metric | Bitmain Antminer L9 (16Gh) |
|---|---|---|
| $3,500 | Upfront cost (MSRP) | $3,199 |
| -$5.11 | Daily net profit | -$8.06 |
| -$5,364 | Net after 1 year | -$6,142 |
| -$7,229 | Net after 2 years | -$9,085 |
| -$9,093 | Net after 3 years | -$12,028 |
| 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.
