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 E9 Pro | Metric | Bitmain Antminer S21 XP Hyd |
|---|---|---|
| $3,000 | Upfront cost (MSRP) | $5,099 |
| -$5.28 | Daily net profit | $3.46 |
| -$4,927 | Net after 1 year | -$3,836 |
| -$6,854 | Net after 2 years | -$2,573 |
| -$8,781 | Net after 3 years | -$1,310 |
| Does not pay back at current rates (negative daily profit) | Payback period | Takes ~4.0 years to pay back at current rates |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
