Cost & ROI Over Time
A miner pays for itself in profit, not specs. These projections track upfront cost against one, two and three years of net earnings at $0.10/kWh.
| Bitmain Antminer S21 XP Immersion | Metric | Innosilicon T3 43T |
|---|---|---|
| $1,593 | Upfront cost (MSRP) | $1,500 |
| $1.07 | Daily net profit | -$3.49 |
| -$1,201 | Net after 1 year | -$2,775 |
| -$809 | Net after 2 years | -$4,050 |
| -$417 | Net after 3 years | -$5,325 |
| Takes ~4.1 years to pay back at current rates | 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.
