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 KS5 Pro | Metric | IceRiver KS3M |
|---|---|---|
| $15,000 | Upfront cost (MSRP) | $8,500 |
| -$6.81 | Daily net profit | -$7.94 |
| -$17,485 | Net after 1 year | -$11,400 |
| -$19,969 | Net after 2 years | -$14,300 |
| -$22,454 | Net after 3 years | -$17,200 |
| 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.
