How this calculator works
The estimate bills your chosen load hours at load wattage and the rest of the day at idle wattage, times 365, times your $/kWh rate. Home servers spend most of their life near idle, which is why a 6W-idle Intel N150 box costs around $7 a year while a 20W-idle workstation-class machine costs three times that before it does any work.
Wattage presets come from the same sourced measurements our reviews cite — wall readings from reviewers like ServeTheHome and NotebookCheck plus consistent owner reports. Real draw varies with configuration, BIOS power settings, and attached drives, so treat results as close estimates rather than guarantees.
