Let’s look at the cost of running box fans based on recent study into box fan wattage.
The typical box fan costs $0.011 per hour and $0.088 per night (i.e. 8 hours) to run in the United States. The average box fan costs 26 cents per day, $1.84 per week, and $8.15 per month if it runs 24 hours a day, seven days a week.

Is it true that box fans consume a lot of energy?
Box fans are among the most energy-efficient cooling devices. However, how effective are them, and which is the most effective? I looked into the wattage of over 100 of the most popular box fans in the United States. Here are the outcomes.
At full speed, box fans consume 73W of power on average. Smaller box fans use 27 watts, while 20-inch box fans use an average of 86.5 watts.
At lower speeds, the amount of watts consumed decreases. Continue reading to learn how many watts are consumed at lower speeds and to learn more about the most popular and energy-efficient box fans available today.
What is the maximum power consumption of a box fan?
Box fans are a popular form of cooling fan, with sizes ranging from a few inches in size for DIY cooling and ventilation projects to 20+ inches in size for larger rooms and smaller areas.
Many people question how much it costs to run a box fan because they can run for hours on end, day after day.
Smaller 7-10 inch box fans, which are used as personal cooling devices and are usually placed on a flat surface near the person, such as a desk, and bigger 18-20 inch box fans, which are frequently positioned on the floor and keep even larger rooms cooler and more pleasant to be in, are the most common.
Note: Box fans and other fans do not lower the temperature of the air they blow/exhaust; instead, cooling is accomplished through the evaporation of moisture from human skin, which is more intense as the air passes over the skin faster.
Smaller box fans (10 inches) use 25-30 watts at maximum air speed, but bigger box fans (20 inches) use 80-100 watts on average, though they can range from 50 to 200 watts.
Check the fan’s label, which is normally located on the rear side or on the bottom of the unit, and/or the Owner’s Guide for the exact wattage of your device.
How much does it cost each hour to run a fan?
Given the assumptions in the chart below, a home pedestal fan will cost between 1 and 2 cents per hour to run, or roughly $14.60 to $29.20 per year. The power output of pedestal fans varies greatly between models. The maximum power (measured in watts) of most home pedestal fans will be 45W to 75W, however bigger commercial pedestal fans may have outputs up to 300W.
The cost of using a pedestal fan is determined by the fan’s wattage and speed setting. It will, of course, be determined by the electricity rate you pay. We utilized a 3-speed pedestal fan with a maximum output of 70W in the example below. We also assume a 28.7c/kWh electricity rate.
In comparison to pedestal fans, modern ceiling fans use less electricity. Because pedestal fans oscillate and must spin at a quicker pace to provide airflow, they are larger than ceiling fans. While ceiling fans may save you a little amount of money on electricity, pedestal fans are much less expensive to buy and require no professional installation.
What is the energy consumption of an electric fan?
Not at all. The cost of running a fan is fairly low. A common ceiling fan, for example, consumes 50 Watts. The expense of running more powerful fans (with wattages of 100W+) can be rather considerable.
The cost of running most fans (10W to 100W) ranges from $0.0013 to $0.0132 per hour. Even if you run a 100W fan at maximum speed for an entire day (24 hours), you will spend about $0.32 per day.
First and foremost, we shall investigate how many watts a fan consumes. We can compute how much electricity a fan uses per hour, per day, per week, or per month using this information.
For instance, how much energy does a ceiling fan consume? A normal 50W fan consumes 0.05 kWh of power each hour. That’s less than a cent per hour with an average electricity price of $0.1319/kWh (0.66 US cents, to be exact). If you ran it for a day (24 hours), the 50W fan would cost you $0.16.
A ‘Fan Power Consumption Calculator’ can be found further down. Simply enter the number of watts your fan produces, and the calculator will determine how much it costs to run that fan every hour.
In addition, we’ve created a fan power consumption chart with computed operating expenses (per hour, day, week, and month) for fans ranging from 10W to 1000W.
Only two pieces of information are required to accurately calculate the running cost of any fan:
- What is the wattage of your fan? This is called as ‘running wattage,’ and it can be found on the fan’s specification sheet or label.
- What is the cost of electricity in your area? Obviously, greater power costs result in higher fan operating expenses.
Before you can use the fan cost calculator, you must first determine the wattage of your fan as well as the cost of electricity (cost per kWh).
Let’s have a look at how much power is used by fans:
Is it possible to run a box fan all night?
Do you like to use your electric fan to create white noise to help you sleep, remain cool, and save money on your utility bill? For all three of these reasons, electric fans can be a terrific way to sleep at night!
The good news is that you may safely leave most conventional electric fans on all night. There are several additional advantages to doing so.
Electric fans (the kind you’d buy in a store, like box fans, tower fans, and pedestal or tabletop fans) are generally safe and dependable. Electric fans like this do not pose any health risks and are unlikely to cause any electrical troubles.
Here are some of the reasons they’re great for staying up all night:
- Some fans (particularly box fans) produce a relaxing white noise that can be used to conceal noise while simultaneously promoting relaxation and sleep. For this reason, many individuals prefer the “white noise” produced by some fans because it helps them sleep better.
- Electric fans, for example, consume a fraction of the energy that a tiny window air conditioner does. (For example, 45 watts vs. 500 watts or more) This means you’ll save money on your electric bill.
- A fan’s soothing humming and/or white noise sound can assist in acclimating your mind and body to sleep time. It’s a healthy habit, similar to having a set nighttime regimen.
Having said that, if you’re going to run a fan all the time, you’ll want to be wise and safe about it. What exactly do I mean? Continue reading to find out more…
Is it possible to leave a box fan running for an extended period of time?
Your ceiling fan, contrary to popular perception, does not keep your home cool. Instead, it prevents your home’s air from becoming stagnant. When you turn on your ceiling fan, you’ll enjoy the nice breeze as well as the steady circulation of warm and chilly air throughout your home.
With that in mind, it’s tempting to leave your fan on for an extended period of time. After all, you’ll want to maintain your home as comfortable as possible if you’re experiencing the dog days of summer. Unfortunately, leaving your fan on all the time can be risky.
When it comes to assessing how long you may leave your ceiling fan on without jeopardizing your home’s safety, consider the size and brand of the ceiling fan you have. Each manufacturer approaches the production of their fans in a unique way. As a result, while deciding whether or not to leave your fan on for a lengthy amount of time, it’s wise to examine the manufacturer’s instructions.
However, it is generally safe to leave your ceiling fan running for eight hours at a time. That doesn’t mean you should panic if you forget to turn off your fan on your way out the door for work, but you should give the fan’s motor a rest as soon as you arrive home.
What does it cost to keep a fan running 24 hours a day?
As you can see from the table above, I compared the electricity expenses of fans and air conditioners, using the average power ratings for both appliances.
It demonstrates that fans use far less energy than air conditioners. Consider this: your central air conditioner cools the entire house, so each room is comfortable.
The central air conditioner will cool all four rooms to a set temperature if you have four. If you have an AC with a high power rating, it will cost you between $100 and $200 every month.
You’ll use 400 Wh of electricity per hour if you don’t use the air conditioner and instead use a 100W ceiling fan in each room.
Your monthly cost would be roughly $38 to $40 if you ran your fans 24 hours a day.
If you have a larger number of fans or fans with a greater power rating, this cost may increase.
This demonstrates that running fans is substantially less expensive than running an air conditioner. Keep in mind, however, that fans merely circulate the air within your room, whereas air conditioners chill the heated air.
