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 Z11 | Metric | Bitmain Antminer Z9 |
|---|---|---|
| $200 | Upfront cost (MSRP) | — |
| $0.45 | Daily net profit | -$1.13 |
| -$36 | Net after 1 year | -$412 |
| +$129 | Net after 2 years | -$824 |
| +$293 | Net after 3 years | -$1,236 |
| Pays for itself in ~15 months at current rates | Payback period | — |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
