I am trying to capture costs for starting into homelab/selfhosting.

VPNs, search engines, absolutely everything and anything.

    Yeah, same. Though at 3-5W … it really is just a very rough guess. Lemme ShitGPT it. Oh, I was way off

    A realistic Pi 4B-only estimate is about A$8–A$12 per year in electricity, assuming it is on 24/7 and used for Jellyfin streaming around 10–12 hours per week.

    Pi 4B measurements are typically around 2.7–2.85 W at idle, about 5.1 W under moderate server load, and around 6.4 W under full CPU stress. Using Perth/WA’s Synergy Home Plan A1 energy charge of 32.3719 c/kWh, excluding the daily supply charge, that works out very cheaply because the device uses only about 25–36 kWh/year.

    Scenario Assumed usage Annual energy Approx. annual cost

    Mostly idle 3 W 24/7 26.3 kWh A$8.51/year Idle + 12h/wk Jellyfin 2.7 W idle, 5.1 W streaming 25.1 kWh A$8.14/year Heavier Jellyfin/server use 2.7 W idle, 6.4 W streaming 26.0 kWh A$8.40/year Conservative wall-power estimate 4 W idle, 6.4 W streaming 36.5 kWh A$11.83/year

    The bigger swing factor is storage, not the Pi. A USB SSD adds very little; a USB-powered 2.5" hard drive might add a few dollars per year; a powered 3.5" external drive left spinning 24/7 could push the total more into the A$15–A$30/year range.

    So, for the Raspberry Pi 4B itself as a Jellyfin box: roughly A$10/year is a good mental estimate.
