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.

Innosilicon A9 ZMaster	Metric	Innosilicon A11 Pro
—	Upfront cost (MSRP)	$4,000
$0.31	Daily net profit	-$6.00
+$113	Net after 1 year	-$6,190
+$227	Net after 2 years	-$8,380
+$340	Net after 3 years	-$10,570
—	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.
