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.
| Antminer D9 | Metric | Bitmain Antminer R4 |
|---|---|---|
| $3,000 | Upfront cost (MSRP) | — |
| -$6.75 | Daily net profit | -$1.71 |
| -$5,463 | Net after 1 year | -$625 |
| -$7,927 | Net after 2 years | -$1,249 |
| -$10,390 | Net after 3 years | -$1,874 |
| Does not pay back at current rates (negative daily profit) | 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.
