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.
| Bitmain Antminer S9i (13Th) | Metric | Innosilicon T3+ |
|---|---|---|
| $65 | Upfront cost (MSRP) | $1,200 |
| -$2.61 | Daily net profit | -$5.55 |
| -$1,018 | Net after 1 year | -$3,224 |
| -$1,971 | Net after 2 years | -$5,249 |
| -$2,925 | Net after 3 years | -$7,273 |
| 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.
