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 D7 | Metric | Bitmain Antminer L11 Pro (21Gh) |
|---|---|---|
| $2,500 | Upfront cost (MSRP) | $7,999 |
| -$7.51 | Daily net profit | -$8.67 |
| -$5,241 | Net after 1 year | -$11,163 |
| -$7,982 | Net after 2 years | -$14,327 |
| -$10,722 | Net after 3 years | -$17,491 |
| 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.
