How Much Does It Cost to Run a Wi-Fi Router in Australia? (2026)
A router runs 24 hours a day, but at 5 to 20 watts it costs very little. Mesh systems with several nodes and combined modem-router units sit at the higher end.
A typical wi-fi router (10 W) costs A$0.003 per hour, or about A$2.52 per month at 24 hours a day in Australia. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (5 W) | A$0.002 | A$0.042 | A$1.26 | A$15.33 |
| Typical (10 W) | A$0.003 | A$0.084 | A$2.52 | A$30.66 |
| High (20 W) | A$0.007 | A$0.17 | A$5.04 | A$61.32 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 24 h/day ≈ 88 kWh per year.
In Australia, with electricity at A$0.35 per kWh (source: AER Default Market Offer 2026–27, 2026-07), a typical wi-fi router costs A$0.003 per hour and about A$30.66 per year at 24 hours a day. Each A$1.00 of electricity buys roughly 285.7 hours of use.
How to lower the cost of running a wi-fi router
- Turning the router off at night saves roughly 3 kWh a year. Most people find the hassle not worth it.
- Replace an old modem plus router pair with a single combined unit to halve draw.
- Disable unused radios such as a guest network on a separate band.
- Avoid running more mesh nodes than your home needs.
Frequently asked questions
Should I turn off my Wi-Fi router at night?
Only for the small saving. A 10 watt router costs less than 90 kWh a year even running continuously.
Does a mesh Wi-Fi system use a lot of electricity?
Each node adds 5 to 10 watts, so a three node system is comparable to a light bulb.
Does a router use more power with more devices connected?
Slightly, but the difference is a watt or two at most.
