Who doesn’t want to enjoy a flow of cool wind, especially during the hot summer? Everyone does. In general, most people use ceiling fans to get comfort during summer days. As ceiling fans are cost-effective and energy-efficient compared to other appliances, it is preferred by most people to enjoy a cool breeze at a low energy cost. Although some ceiling fans use more energy than other models, the overall energy consumption of ceiling fans is far less than other appliances in the home. Moreover, the energy consumption of ceiling fans may vary from brand to brand. Therefore, it becomes essential for an average person to calculate the power consumption of a ceiling fan before buying that.
In this article, we are going to discuss how to calculate the power consumption of a ceiling fan using its wattage. Also, we will talk about how much it can cost to use a ceiling fan. So, keep reading to know whether ceiling fans are an efficient appliance to use.
Finding the Wattage of a Ceiling Fan
Table of Contents
In order to calculate the power consumption of a ceiling fan, you need to find the wattage of the fan first. Most ceiling fans can consume from 10 to 120 watts per hour. Usually, you can find the wattage of your ceiling fan on the box it came in. If you don’t find the wattage there, then you can also refer to the manual of the fan to find the wattage. Also, it can be found on the fan or the blade. If the wattage of the fan is not available anywhere, then you can visit the manufacturer’s website and search for the wattage of the ceiling fan model you have.
Another method of finding the wattage of a ceiling fan is by finding the ampere rating. The ampere rating of the fan can be easily found written on the box. If the ampere rating of the fan is more, then the wattage also will be more.
After finding the ampere rating, you can multiply it with voltage to determine the wattage of the ceiling fan. For example, if the ampere rating of the fan is 0.3, then you can multiply it with the operating voltage of the fan, which is 220V.
This will be 220 X 0.3 = 66 watts.
This is the wattage of the fan when it runs at its maximum speed. Also, it is the power consumption of the ceiling fan per hour. This means the fan will consume 66 watts of power per hour. From this number, you can calculate the power consumption of the fan per hour, day, month, and even year.
Calculating the power consumption of a ceiling fan per hour
Usually, power consumption is measured in kilowatts. So you need to convert the watts into kilowatts first. To do that, you need to divide 66 by 1000.
This will be 66 / 1000 = 0.066 kilowatts.
So the power consumption of the fan per hour is 0.066 KWh.
To determine the energy cost per hour, you can multiply this number with the amount that your electricity suppliers charges per unit. For example, if the electricity rate per unit is 5 rupees, then you can multiply it with the total power consumption per hour to find the cost per hour.
i.e. 0.066 X 5 = 0.33 rupees
Therefore, the ceiling fan will use 0.33 rupees of electricity.

Calculating the power consumption of a ceiling fan per day
You can determine the power consumption of the ceiling fan per day by defining how many hours you use the fan a day. If you use the fan for 8 hours per day, then the power consumption of the fan will be as follows:
0.066 X 8 = 0.528 kilowatts.
So per day, the ceiling fan will consume 0.528 kilowatts. If you want to know the energy cost per day, then you can multiply it with 5 rupees.
This will be 0.528 X 5 = 2.64 rupees.
Thus the ceiling fan will cost you 2.64 rupees per day.
Calculating the power consumption of a ceiling fan per month
As you know, the average power consumption of your ceiling fan per day, you can multiply it with the number of days of a month to find the power consumption per month.
If the power consumption per day is 0.528 KWh, then the power consumption per month will be as follows:
0.528 X 30 = 15.84 kilowatts
And the energy cost per month will be 15.84 X 5 = 79.2 rupees.
So the ceiling fan will consume 15.84 units of power in a month of 30 days, which will cost you 79.2 rupees.
This way, you can calculate the power consumption of the ceiling fan per year, which will be 0.528 X 365 = 192.72 kilowatts.
Now, you know that a ceiling fan consumes a very less amount of power which costs you less money. This is the reason why these common appliances are very popular among people.
If you compare the power consumption of a ceiling fan with the power consumption of an air conditioner, then you can notice a huge difference. Still, many people prefer using air conditioners as they actually cool the room. Also, some other people use both of them to create an ideal temperature in their homes. However, the choice is yours, which one you will choose.
How to reduce power consumption while using a ceiling fan?
Although ceiling fans consume a very less amount of power, you can save electricity and a little money by using them efficiently.
- Keep the fan off when you are not there
Ceiling fans consume less power, that doesn’t mean that you will run them idly. If you are not in the room, then make sure the fan is off. This way, you can save electricity and money easily.
- Don’t use the ceiling fans with lights
Usually, some ceiling fans come with LED lights that look attractive and enhance the look of your home. But such ceiling fans commonly use more electricity than ceiling fans without lights. So, you can opt for a ceiling fan that has no LED lights with it if you want to save electricity and save your cost.
At the end of the day, ceiling fans are efficient appliances to use as they consume low power and cost you little money. If you don’t want to opt for an air conditioner, then the ceiling fan is the best choice for you. From the above power consumption calculations and explanations, it is clear that ceiling fans are cost-effective and energy-efficient appliances to use. Therefore, you can consider installing ceiling fans in your home if you want to save your energy cost.
