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 Z15 | Metric | Bitmain Antminer Z15 Pro |
|---|---|---|
| $998 | Upfront cost (MSRP) | $1,800 |
| $11.49 | Daily net profit | $23.56 |
| +$3,197 | Net after 1 year | +$6,801 |
| +$7,393 | Net after 2 years | +$15,402 |
| +$11,588 | Net after 3 years | +$24,002 |
| Pays for itself in ~87 days at current rates | Payback period | Pays for itself in ~76 days at current rates |
At the default rate, the Bitmain Antminer Z15 Pro reaches break-even first — but plug in your own electricity cost above, since payback shifts sharply with it.
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
