Cost & ROI Over Time
Sticker price versus what the miner actually earns back: the table below projects cumulative net profit at a $0.10/kWh electricity rate.
| Bitmain Antminer Z11 | Metric | Bitmain Antminer Z15 Pro |
|---|---|---|
| $200 | Upfront cost (MSRP) | $1,800 |
| $1.45 | Daily net profit | $23.55 |
| +$331 | Net after 1 year | +$6,796 |
| +$861 | Net after 2 years | +$15,392 |
| +$1,392 | Net after 3 years | +$23,988 |
| Pays for itself in ~5 months 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.
