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 (200Th) | Metric | Antminer T21 |
|---|---|---|
| $1,076 | Upfront cost (MSRP) | $4,200 |
| -$1.32 | Daily net profit | -$1.83 |
| -$1,558 | Net after 1 year | -$4,866 |
| -$2,041 | Net after 2 years | -$5,533 |
| -$2,523 | Net after 3 years | -$6,199 |
| 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.
