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.
| Antminer S21+ | Metric | Whatsminer M60S++ |
|---|---|---|
| $6,500 | Upfront cost (MSRP) | $7,000 |
| -$0.90 | Daily net profit | -$1.71 |
| -$6,829 | Net after 1 year | -$7,624 |
| -$7,158 | Net after 2 years | -$8,249 |
| -$7,487 | Net after 3 years | -$8,873 |
| Does not pay back at current rates (negative daily profit) | 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.
