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.
| Innosilicon A4+ LTCMaster | Metric | Bitmain Antminer L9 (17Gh) |
|---|---|---|
| $3,500 | Upfront cost (MSRP) | $3,380 |
| -$1.80 | Daily net profit | -$8.57 |
| -$4,157 | Net after 1 year | -$6,507 |
| -$4,814 | Net after 2 years | -$9,634 |
| -$5,471 | Net after 3 years | -$12,761 |
| 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.
