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.
| Antminer T21 | Metric | Innosilicon T3 43T |
|---|---|---|
| $4,200 | Upfront cost (MSRP) | $1,500 |
| -$3.25 | Daily net profit | -$3.81 |
| -$5,386 | Net after 1 year | -$2,892 |
| -$6,573 | Net after 2 years | -$4,285 |
| -$7,759 | Net after 3 years | -$5,677 |
| 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.
