Wifi routers are common nowadays in house and offices to communicate between multiple devices and also access the web. As wifi routers are working throughout the day (24 hours) their power consumption would be high? but that’s not the case as they are very energy efficient.

The average wattage of wifi router varies from 3 watts to 20 watts. To calculate monthly power consumption of a wifi route, multiply it’s wattage by number of operational hours in a month.

Let’s see how to calculate power consumption of a wifi router.

To calculate power consumption of any wifi router you need to know three things, 

  1. Wattage of wifi router: Watt is the unit of power. It means the rate at which electricity is consumed or produced by a device. For example a 75 watt ceiling fan consumes power at a rate of 75 watts per hour, it does not mean that the ceiling fan consumed 75 units of electricity, it means it will consume power at a rate of 75 watts every hour.
  2. Operational hours of wifi router: Operational hours of any device refers to number of hours the device is working. Generally wifi router are ON throughout the day, so operational hours would be 24 in a day.
  3. Electricity Tariff:  Electricity tariff is the amount the electricity provider charges you for one unit (kWh) of electricity. I live in Mumbai, India here the electricity tariff is Rs 12/kWh. If you don’t know how to calculate your tariff then just divide your total bill by monthly power consumption and you will get your electricity tariff.Power

To calculate the power consumption of your wifi using the below calculator just put the wattage of your wifi router, operational hours and electricity tariff in your locality and you will get the units of electricity consumed by your wifi and the impact it has on your electricity bill.

You can find the wattage of your wifi router from the sticker on the back of it.

If you can’t find the rated power of your wifi router over there, then just find a similar type wifi router on amazon and check its wattage in the product description.

To give you a rough estimate the average rated power of a wifi router is between 3 watt to 20 watt.  For average home wifi routers you can take 6 watts as rated power for calculation.

Calculate Power Consumption Of A Wifi Router:

The kilowatt hour consumed by the wifi is the number of units of electricity your wifi consumed in that much amount of time. 

Calculate Power Consumption Of A Wifi Using Kill A Watt Meter:

The above calculated results are average approximation, if you want to know exact power consumption of your wifi router then you can do that with the help of a Kill A Watt Meter.

Kill A Watt Meter is a simple device which gives real time data of power consumption of any device.

You can check it on amazon using this link – Kill A Watt Electricity Usage Monitor

To use a Kill A Watt meter to calculate the power consumption of your wifi, first connect your wifi to the Kill A Watt meter and then plug the Kill A Watt meter to your wall socket and you are good to go.

Then start using your wifi and you can see in real time how many kWh (units) of electricity your wifi router is consuming.

To get exact power consumption it is advised to take the reading for 3-7 days of operation.
