Electricity Cost Calculator
Use board power as a planning input for always-on boxes, inference nodes, and home AI rigs.
The default utility rate uses the same planning assumption as the current buyer's guide. Replace it with your real rate.
Planning watts 150W
Monthly energy 108.0 kWh
Monthly cost $12.96
Yearly cost $157.68
Board power is a safe planning ceiling, not a promise of real-world average inference draw. Long prompts, idle time, undervolting, and your workload mix will change the final bill.
