tower fan power consumption

If you are planning to buy a new tower fan or wondering how much electricity your existing tower fan is consuming then this article is for you. In this article, we will calculate the power consumption of a tower fan and also look at how much it costs to use one.

Also by the end, you will learn to calculate the power consumption of any fan using a simple calculator.

Tower fans are normally rated between 25 watts to 80 watts. A 40 watt tower fan running for 8 hours in a day will consume around 0.32 kWh of electricity in a day. This adds up to around 9.6 kWh of electricity in a month.

Hence, the cost to run this 40 watt tower fan for 8 hours a day for an entire month will be $ 2.47 in Los Angeles, £ 3.46 in London, and Rs 96 in Mumbai.


Tower Fan Power Consumption:

The power consumption of a tower fan (for that matter any electrical appliance) depends upon two main things,

  1. First is the wattage of your tower fan,
  2. And second is the electricity tariff in your area.

Before we jump into calculating the power consumption of your tower fan let’s see what these terms are and how you can find out your tower fan’s wattage and the electricity tariff of your locality.

If you already know these terms and just want to use the calculator then please scroll down to see the power consumption table and use the calculator.


What is the Wattage of A Tower Fan:

The wattage of a tower fan varies from 25 watts to 80 watts, generally, the bigger the size, the higher the wattage, and the more air it can push forward.

You can find the wattage of your tower fan by reading the label on it or just look for your tower fan on amazon and you will find its wattage in the description section.

At the end of this article, I have put together a table that shows the power consumption of a range of tower fans with different wattages.

If this whole talk about wattage and electricity is confusing you then here is a quick explanation about what is watt.

Watt is the unit of power. It means the rate at which electricity is consumed or produced by a device. For example, a 50-watt TV consumes power at a rate of 50 watts per hour, it does not mean that the TV consumed 50 units of electricity, it means it will consume power at a rate of 50 watts every hour.

So in short, the wattage of a tower fan lies between 25 watts to 80 watts and you can find it by looking at the label on it. With that out of the way, let’s look at what is electricity tariff.


What is your Electricity Tariff:

In simple words, an electricity tariff is the amount your electricity provider charges you for one unit (kWh) of electricity. I live in Mumbai, India here the electricity tariff is Rs 12/kWh.

(What is a Kilowatt hour (kWh) Kilowatt hour or unit of electricity is the energy consumption of a device. For example, a 50-watt fan running for 50 hours will consume 50 watts x 50 hours = 2500-watt hours = 2.5-kilowatt hours of electricity = 2.5 units of electricity. (1 kWh of electricity = 1 unit of electricity))

To find your electricity tariff, just look into your previous month’s electricity bill and find out your monthly electricity consumption, then just divide your monthly electricity consumption by your total monthly electricity bill, the figure you get is approximately your electricity tariff.

I have put together the following table that shows the electricity tariff of a few countries.

Electricity Tariff Around The World:

Calculate Tower Fan Power Consumption:

With these two pieces of information in hand, you are ready to find the power consumption of your tower fan.

tower fan 35Watt
Tower Fan 35-Watts

Let me show you an example,

I have selected a 35-watt tower fan listed on amazon. Let’s assume we will be using it for 8 hours every day throughout the year.

Hence, we will calculate the power consumption of this 35-watt tower fan in a day, in a month, and in an entire year.

With the knowledge of your tower fan wattage and your electricity tariff, just use this simple formula to calculate power consumption.

Power consumption of an appliance = Wattage of an appliance X operational hours

Cost to run an appliance = Power consumption of an appliance X electricity tariff.

(Operational hours is basically the number of hours you are using your tower fan)

Now let’s calculate


Electricity consumption of A 35-Watt Tower Fan:

In our case, wattage is 35-watt and operational hours are 8 hours in a day, 240 hours in a month, and 2,920 hours in a year.

Hence by using the above formula.

  • Power consumption of a 35-watt tower fan in a day (8 hours) = 35-watt X 8 hours = 280 wh.
  • Similarly, Power consumption of a 35-watt tower fan in a month (8 hours/day @ 30days) = 35-watt X 240 = 8.4 kWh.
  • And Power consumption of a 35-watt tower fan in a year (8 hours/day @ 365 days) = 35-watt X 2,920 = 102.2 kWh.

Now that you know the power consumption just multiply it by your electricity tariff and you will get to know the cost you to run your tower fan.

let’s calculate how much it will cost to run this 35-watt tower fan for 8 hours every day for an entire month in Los Angeles, London, and Mumbai.

  • In Los Angeles, the electricity tariff in Los Angeles is around 25.8 cents per kilowatt hour (kWh), hence it will cost around $ 2.16 (8.4 kWh X 25.8 cents) to run this 35-watt tower fan for 8 hours every day for an entire month.
  • In London, the electricity tariff in London is around 36p/kWh, hence it will cost around £ 3.02 (8.4 kWh X 36p/kWh) to run this 35-watt tower fan for 8 hours every day for an entire month.
  • In Mumbai, the electricity tariff in Mumbai is around Rs 10 per kilowatt hour (kWh), hence it will cost around Rs 84 (8.4 kWh X Rs 10) to run this 35-watt tower fan for 8 hours every day for an entire month.

For your reference, I have calculated the cost to run this 35-watt tower fan for 8 hours daily throughout the entire year in Los Angeles, London, and Mumbai.

Country (Tariff)Daily Power Consumption of a Tower Fan
(35-watt @ 8 hours)
Monthly Power Consumption of a Tower Fan
(35-watt @ 240 hours)
Annual Power Consumption of a Tower Fan
(35-watt @ 2,920 hours)
Los Angeles (25.8 c/kWh)0.28 kWh, cents 7.228.4 kWh, $ 2.16102.2 kWh, $ 26.36
London (36p/kWh)0.28 kWh, pence 10.088.4 kWh, £ 3.02102.2 kWh, £ 36.79
Mumbai (Rs 10/kWh)0.28 kWh, Rs 2.808.4 kWh, Rs 84102.2 kWh, Rs 1,022

The above figures show the approximate power consumption of a 35-watt tower fan, however, the actual power consumption will be 5% to 10% lower than this.

Also, every tower fan has 3 to 5-speed settings, hence, if you are using your fan at low speed then the power consumption will be lower than this.

How lower? From the calculation I did on my tower fan, the difference in the power consumption between the top speed and the lowest speed is between 20% to 30%.


How Much Electricity Does a Tower Fan Consume in 24 hours?

For your reference, I have made the below table which shows the power consumption of a range of tower fans having different wattages running for 24 hours every day for an entire month.

60 watts1.44 kWh43.20 kWh525.6 kWh
80 watts1.92 kWh57.60 kWh700.8 kWh

As you can see, even if you run an 80-watt tower fan for 24 hours a day for an entire month, it will consume 1.92 kWh of electricity in a day and 57.60 kWh of electricity.

How Much Does it Cost Ro Run A Tower Fan For 24 Hours?

From the above table, we can see that the cost to run an 80-watt tower fan for 24 hours a day will roughly be equal to:

  • $ 0.50 in LA. (1.92 kWh X $ 0.258/kWh)
  • £ 0.69 in London. (1.92 kWh X £ 0.36/kWh)
  • Rs 19.20 in Mumbai, India. (1.92 kWh X Rs 10/kWh)

And the cost to run an 80-watt tower fan for 24 hours a day for an entire month will roughly be equal to:

  • $ 14.86 in LA. (57.60 kWh X $ 0.258/kWh)
  • £ 20.73 in London. (57.60 kWh X £ 0.36/kWh)
  • Rs 576 in Mumbai, India. (57.60 kWh X Rs 10/kWh)

Now go ahead and use the below calculator to find out the power consumption of your tower fan.

Just type the wattage of your tower fan, the number of hours of usage, and your electricity tariff, and let the calculator do the math for you.


Tower Fan power consumption calculator:

As I said before, these are approximate values and the actual power consumption will depend on the speed setting of your fan. The calculated values are definitely on the higher side, you can expect actual power consumption to be 10% – 20% lower.

If you are not happy with the approximate results and you want to know the exact power consumption, then I would suggest you buy a cheap Kill-A-Watt Meter from amazon.


Calculate the exact power consumption of any Appliance using Kill A Watt Meter:

Kill A Watt Meter is a simple device that gives real-time data on the 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 tower fan, first, connect your tower fan plug into the kill-a-watt meter and then plug the kill-a-watt meter in your wall socket and you are good to go.

Then start using your tower fan and you can see in real-time how many kWh (units) of electricity it is consuming.
