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.
How much does it cost to have a fan running 24 hours a day, seven days a week?
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.
Continue reading to learn how the power consumption compares to other appliances and to receive a breakdown of the running costs by size and country. Additionally, learn how to calculate your own box fan operating expenses or use the Box Fan Electricity Cost Calculator below.
Is it true that fans consume a lot of electricity?
Is it true that fans consume a lot of electricity? Running a fan uses far less energy than running an air conditioner; ceiling fans use between 15-90 watts on average, while tower fans use roughly 100 watts.
A 20-inch box fan consumes how much electricity?
bBox fans can run all day if needed, which can raise electricity expenditures.
For example, a 20-inch 100W box fan that works at maximum power for 10 hours per day consumes 1 kWh of energy every day.
The cost of an average kWh of energy fluctuates, but it’s reasonable to presume it’s less than 15 cents per kWh.
That means that if you operate a 100W box fan for 10 hours per day, your operating costs will be 15c per day, or 4.5 $US per month if you run it every day for 10 hours.
Similarly, if you have a 10-inch 30W desk box fan that runs for 8 hours per day, you’ll use 240 Wh per day and 7.2 kWh per month, or 1.1 $US a month if you use it every day for 8 hours…
Of course, if a modest USB Desk Fan is more than enough for you, you may ignore the extra electricity expenditures…
Is it true that box fans save energy?
Varying types of fans use different amounts of energy and produce different results.
The most important findings from a study of thousands of different fans, as well as a comparison of different fan types and the most efficient fan models, are shown here.
Here are a few spoilers:
- Ceiling fans are the most energy-efficient form of fan, moving the most air per watt.
- For personal cooling, box fans are the most efficient.
- The average cost of running a fan in the United States is $0.0059 per hour.

What in a house wastes the most electricity?
The breakdown of energy use in a typical home is depicted in today’s infographic from Connect4Climate.
It displays the average annual cost of various appliances as well as the appliances that consume the most energy over the course of the year.
Modern convenience comes at a cost, and keeping all those air conditioners, freezers, chargers, and water heaters running is the third-largest energy demand in the US.
Here are the things in your house that consume the most energy:
- Cooling and heating account for 47% of total energy consumption.
- Water heater consumes 14% of total energy.
- 13 percent of energy is used by the washer and dryer.
- Lighting accounts for 12% of total energy use.
- Refrigerator: 4% of total energy consumption
- Electric oven: 34% energy consumption
- TV, DVD, and cable box: 3% of total energy consumption
- Dishwasher: 2% of total energy consumption
- Computer: 1% of total energy consumption
One of the simplest ways to save energy and money is to eliminate waste. Turn off “vampire electronics,” or devices that continue to draw power even when switched off. DVRs, laptop computers, printers, DVD players, central heating furnaces, routers and modems, phones, gaming consoles, televisions, and microwaves are all examples.
A penny saved is a cent earned, and being more energy efficient is excellent for your wallet and the environment, as Warren Buffett would undoubtedly agree.
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.
On low, how many watts does a box fan consume?
Smaller box fans (those less than or equal to 10 inches) utilize 27W on average, according to research into nearly 100 of the most popular box fans.
Small box fans have the lowest reported wattage of 5W and the highest recorded wattage of 45W.
Surprisingly, the lowest recorded wattage box fan is slightly lower than the lowest recorded wattage tower fan (6W). Check out the Tower Fan vs. Box Fan section for further information.
Don’t miss the Ceiling Fan vs Box Fan section here to discover how box fans stack up against ceiling fans.
How much power does a fan consume per hour?
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…
