Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| Innosilicon A9 ZMaster | Metric | Bitmain Antminer Z15 Pro |
|---|---|---|
| — | Upfront cost (MSRP) | $1,800 |
| $0.31 | Daily net profit | $23.55 |
| +$114 | Net after 1 year | +$6,796 |
| +$227 | Net after 2 years | +$15,392 |
| +$341 | Net after 3 years | +$23,988 |
| — | Payback period | Pays for itself in ~76 days 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.
