About this calculator

Electricity cost follows a simple relationship: energy (kWh) = power draw (W) ÷ 1000 × hours running, and multiplying that by your utility's price per kWh gives the cost for any period. Since a home server, NAS, or router typically runs 24/7 rather than a few hours a day like most appliances, even a modest 30–50 watt draw adds up to a meaningful yearly bill once you extrapolate daily use to a full year.

This calculator takes your device's wattage, daily runtime, and local electricity rate and breaks the cost down into daily, monthly, and yearly figures alongside total energy consumed. Home-lab and self-hosting enthusiasts use it to compare the running cost of an always-on Plex server, NAS, or Raspberry Pi cluster against cloud hosting, while small office and IT admins use it to budget for always-on network equipment.
