If you are planning to buy a new table fan or wondering how much electricity your existing table fan is consuming then this article is for you. In this article, we will calculate the power consumption of a table 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.
Table fans are normally rated between 30 watts to 60 watts, the larger the blade size, the higher is the wattage. A 40 watt table 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.
This would roughly translate to a monthly electricity cost of $ 2.47 in Los Angeles, £ 3.45 in London, and Rs 96 in Mumbai.
Table Fan Power Consumption:
The power consumption of a table fan (for that matter any electrical appliance) depends upon two main things,
Before we jump into calculating the power consumption of your table fan let’s see what these terms are and how you can find out your table 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 Table Fan:
The wattage of a table fan varies from 30 watts to 60 watts, generally speaking, the larger the blade size, the higher the wattage and the more volume of air it can push.
You can find the wattage of your table fan by reading the label on it or just look for your table fan on amazon and you will find its wattage in the description section.
As a general rule of thumb, the following blade sizes have respective wattage.
|8 inch||40 Watt|
|12 inch||50 Watt|
|16 inch||55 Watt|
In the later part of this blog, I have put together a table that shows the power consumption of a range of table 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 table fan lies between 30 watts to 60 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, 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 unit of electricity or Kilowatt hour (kWh) – Kilowatt hour or units of electricity is the energy consumption of a device. For example, a 50-watt table 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:
|Country||Electricity Tariff||Country||Electricity Tariff|
|United States||$ 0.154/kWh||India||Rs 6/kWh|
|United Kingdom||£ 0.27/kWh||Germany||€ 0.44/kWh|
|Canada||C$ 0.30/kWh||Philippines||₱ 9.70/kWh|
|Australia||A$ 0.32/kWh||South Africa||R 2.558/kWh|

Calculate Table Fan Power Consumption:
With these two pieces of information in hand, you are ready to calculate the power consumption of your table fan.
Let me show you an example,
I have selected a 40-watt table 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 40-watt table fan in a day, in a month, and in an entire year.
With the knowledge of your table fan’s wattage and your electricity tariff, just use this simple formula to calculate power consumption.
Power consumption of an appliance = Wattage of the appliance X operational hours.
Cost to run an appliance = Power consumption of the appliance X electricity tariff.
(Operational hours is basically the number of hours you are using your table fan).
Now let’s calculate,
Electricity consumption of A 40-Watt Table Fan:
In our case, wattage is 40-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 40-watt table fan in a day (8 hours) = 40-watt X 8 hours = 320 wh.
- Similarly, Power consumption of a 40-watt table fan in a month (8 hours/day @ 30days) = 40-watt X 240 = 9.6 kWh.
- And Power consumption of a 40-watt table fan in a year (8 hours/day @ 365 days) = 40-watt X 2920 = 116.8 kWh.
Now that you know your table fan’s power consumption just multiply it by your electricity tariff and you will get how much it will cost you to run it.
let’s calculate how much it will cost to run this 40-watt table fan for 8 hours every day for an entire month in Los Angeles, London, and Mumbai.
- Los Angeles, the electricity tariff in Los Angeles is around 25.8 cents per kilowatt hour (kWh), hence it will cost around $ 2.48 (9.6 kWh X 25.8 cents) to run this 40-watt table fan for 8 hours every day for an entire month.
- London, the electricity tariff in London is around 36p/kWh, hence it will cost around £ 3.45 (9.6 kWh X 36p/kWh) to run this 40-watt table fan for 8 hours every day for an entire month.
- Mumbai, the electricity tariff in Mumbai is around Rs 10 per kilowatt hour (kWh), hence it will cost around Rs 96 (9.6 kWh X Rs 10) to run this 40-watt table fan for 8 hours every day for an entire month.
For your reference, I have calculated the cost to run this 40-watt table fan for 8 hours every day throughout the entire year in Los Angeles, London, and Mumbai.
|Country (Tariff)||Daily Power Consumption of a Table Fan|
(40-watt @ 8 hours)
|Monthly Power Consumption of a Table Fan|
(40-watt @ 240 hours)
|Annual Power Consumption of a Table Fan|
(40-watt @ 2,920 hours)
|Los Angeles (25.8 c/kWh)||0.32 kWh, cents 8.26||9.6 kWh, $ 2.48||116.8 kWh, $ 30.13|
|London (36p/kWh)||0.32 kWh, pence 11.52||9.6 kWh, £ 3.45||116.8 kWh, £ 42.05|
|Mumbai (Rs 10/kWh)||0.32 kWh, Rs 3.20||9.6 kWh, Rs 96||116.8 kWh, Rs 1,168|
The above figures show the approximate power consumption of a 40-watt table fan, however, the actual power consumption will be 5% to 10% lower than this.
Also, every table 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 table fan, the difference in the power consumption between the top speed and the lowest speed is around 20%.
How Much Electricity Does a Table Fan Consume in 24 hours?
For your reference, I have made the below table which shows the power consumption of a range of table fans having different wattages running for 24 hours every day for an entire year.
|Table Fan Wattage||Daily Power Consumption|
|Monthly Power Consumption|
|Annual Power Consumption|
|30 watts||0.72 kWh||21.60 kWh||262.8 kWh|
|40 watts||0.96 kWh||28.80 kWh||350.4 kWh|
|55 watts||1.32 kWh||39.60 kWh||481.8 kWh|
|60 watts||1.44 kWh||43.20 kWh||525.6 kWh|
As you can see, even if you run a 60-watt table fan 24 X 7 for an entire month, it will only consume 43.20 kWh of electricity.
How Much Does it Cost Ro Run A Table Fan For 24 Hours?
From the above table, we can see that the cost to run a 60-watt table fan for 24 hours a day will roughly be equal to:
- $ 0.37 in LA. (1.44 kWh X $ 0.258/kWh)
- £ 0.51 in London. (1.44 kWh X £ 0.36/kWh)
- Rs 14.40 in Mumbai, India. (1.44 kWh X Rs 10/kWh)
And the cost to run a 60-watt table fan for 24 hours a day for an entire month will roughly be equal to:
- $ 11.14 in LA. (43.20 kWh X $ 0.258/kWh)
- £ 15.55 in London. (43.20 kWh X £ 0.36/kWh)
- Rs 432 in Mumbai, India. (43.20 kWh X Rs 10/kWh)
Now go ahead and use the below calculator to calculate the power consumption of your table fan.
Just type the wattage of your table fan, the number of hours of usage, and your electricity tariff, and let the calculator do the math for you.
Table Fan power consumption calculator:
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.
