I have a wonderful family and a great … mpact on a high electric bill is negligible. Most modern routers consume between 5 and 20 watts, resulting in a monthly saving of approximately $0.50 to $2.00 depending on local utility rates. While technically effective at reducing standby power, it is not a significant solution for major energy spikes.

What Is Saving Electricity by Unplugging WiFi Router?
The practice involves disconnecting your wireless networking equipment from the power source during periods of non-use, typically at night or while away from home. This is based on the principle of reducing “phantom load” or “vampire power,” which refers to the energy consumed by electronic devices while they are plugged in but not actively performing their primary function.
In the context of a modern home, the WiFi router is one of the few devices that remains powered on 24 hours a day, 365 days a year. Proponents of this method suggest that because the router is always active, it contributes a consistent, albeit small, amount to the total kilowatt-hour (kWh) usage reflected on a monthly utility statement.
While the concept is rooted in basic electrical physics—eliminating a load reduces consumption—the actual scale of the savings is often misunderstood. In a household facing a $400 electric bill, the router typically accounts for less than 1% of the total energy expenditure.
How Does It Work?
Unplugging a router works by physically breaking the electrical circuit, ensuring that the device’s internal components, such as the processor, radio transmitters, and LED status lights, draw zero current. When a router is “on” but idle, it continues to broadcast signals and maintain a connection to the Internet Service Provider (ISP), which requires a steady stream of electricity.
The power consumption of a router is measured in watts. To calculate the potential savings, one must convert the wattage to kilowatt-hours using the following formula:
$$(Watts \ imes Hours) / 1000 = kWh$$
What Evidence Says
Technical data from energy monitoring tests consistently shows that standard consumer routers draw between 5W and 15W, while high-performance mesh systems or gaming routers may draw up to 30W. Controlled studies by energy agencies indicate that while unplugging devices reduces “base load” power, the financial return is minimal. For instance, a 10W router running 24⁄7 uses 7.2 kWh per month. At an average US rate of $0.16 per kWh, the cost is roughly $1.15 per month.
Does I Washington State Department of Health t Really Work?
Depends.
Unplugging your router does work to reduce electricity consumption, but it does not work as a meaningful strategy to combat a $400 electric bill. If the goal is strictly to eliminate wasted energy, the action is successful. However, if the goal is to see a noticeable reduction in a high-cost utility bill, the impact is statistically insignificant compared to HVAC systems, water heaters, or large appliances.

The claim that you can save money by unplugging your router is legitimate in a literal sense, but it is often presented with “mixed feedback” regarding its practicality. There are no fraudulent claims involved in the physics of the savings, yet “consumer concerns” often arise regarding the trade-offs.
Most experts categorize this as a low-priority energy-saving tip. There is “limited evidence” to suggest that frequent power-cycling is beneficial for the hardware, and some users report “consumer concerns” regarding the time it takes for mesh systems to reboot and reconnect smart home devices, which may outweigh the few cents saved in electricity.

FAQ Section
Does unplugging my router at night save a lot of money?
No, it does not provide significant savings. Most routers cost between $0.03 and $0.07 per day to operate, meaning you would likely save less than $1.00 per month by unplugging it for 8 hours every night.
Can frequently unplugging a router damage it?
It is unlikely to cause immediate damage, but it can lead to mechanical wear on the power port. Additionally, interrupting power during a background firmware update could potentially corrupt the device’s software.
Will my smart home devices work if I unplug the router?
No, most smart home devices require a continuous internet connection to function. Features like remote camera monitoring, voice assistants, and app-controlled lighting will be disabled until the router is powered back on.
Is it better to use a timer for my WiFi router?
Using a digital timer can automate the process, but the timer itself consumes a small amount of electricity (1-2 watts). This further reduces the already slim margins of energy savings achieved by turning off the router.
Why is my electric bill so high if it isn’t the router?
High electric bills are typically caused by space heating, air conditioning, water heaters, or malfunctioning large appliances. A $400 bill is usually the result of seasonal temperature extremes or poor home insulation rather than small electronics.
Does a WiFi router use more data if it stays on?
Staying on does not inherently increase data usage, but it does allow background processes and updates to occur. The electricity usage remains relatively constant regardless of whether you are actively browsing or if the device is idle.
Should I unplug my mesh WiFi nodes too?
If you are attempting to save electricity, you would need to unplug all nodes in a mesh system to see any effect. However, the total savings would still remain very low, typically adding only a few cents per node to your monthly total.
