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 S23 Immersion (442Th) | Metric | Whatsminer M56 |
|---|---|---|
| $8,800 | Upfront cost (MSRP) | $5,000 |
| $3.36 | Daily net profit | -$6.26 |
| -$7,575 | Net after 1 year | -$7,285 |
| -$6,350 | Net after 2 years | -$9,570 |
| -$5,125 | Net after 3 years | -$11,854 |
| Takes ~7.2 years to pay back at current rates | Payback period | Does not pay back at current rates (negative daily profit) |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
