A typical Wi-Fi router (10 W) costs $0.003 per hour, or about $1.80 per month at 24 hours a day in New Jersey. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (5 W) | $0.001 | $0.030 | $0.90 | $10.95 |
| Typical (10 W) | $0.003 | $0.060 | $1.80 | $21.90 |
| High (20 W) | $0.005 | $0.12 | $3.60 | $43.80 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 24 h/day ≈ 88 kWh per year.
One day of a Wi-Fi router (0.24 kWh) is the same electricity as
- 2.4kettle boils
- 4.8hours of a fridge
- 5.3hours of a laptop
- 27hours of an LED bulb
In New Jersey, with electricity at $0.25 per kWh (source: EIA Table 5.6.A, 2026-06), a typical wi-fi router costs $0.003 per hour and about $21.90 per year at 24 hours a day.

How to lower the cost of running a Wi-Fi router

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.
