Fan (Table) Energy Calculator (Cost and kWh Usage)


When it comes to energy consumption, we often don’t think about how much an individual appliance consumes. For example, a table fan uses an average of 10 watts of power to operate. This may not seem like a lot, but it can quickly add up over time. To put it into perspective, leaving a table fan on for 24 hours a day for a month can consume up to 7.2 kWh of energy.


How To Use This Calculator

Using this energy calculator is a simple and will help you determine the costs of running your appliance. Click on ‘Calculate’ to use the predefined values, or enter your daily usage in hours, appliance watts, and your current energy costs in dollars. The calculator will provide you with the daily, monthly, and yearly results. It’s important to ensure the accuracy of the information entered to get the most accurate results.

Hours Used Per Day

Enter the number of hours you estimate the appliance will be on throughout the day. To use fractions of an hour please use a decimal point in the form.

For example: 1 hour and 30 mintes would be 1.5, and 3 hours and 15 minutes would be 3.25

Power Used in Watts

The calculator already includes a default average wattage. If your appliance uses a different wattage then enter it in the calculator.

Your Energy Rate in kWh

The calculator includes an average energy rate (price in $/kWh) to use for the calculation. This may not be the exact price that you’re currently paying for electricity. If you know your energy rate please enter your price per kilowatt-hour.

Why is energy consumption important?

Energy consumption is a significant factor in our daily lives. It affects both the environment and our wallets. By understanding the impact of our energy usage, we can make informed decisions that not only save us money but are also better for the planet. It’s essential for us to conserve energy wherever possible, and that includes taking a closer look at the appliances we use in our daily lives.

Cost in Dollars of Energy Usage

To calculate the cost of energy usage for a table fan, we can use the following formula:

Energy consumption (kWh) x Energy price ($/kWh) = Cost of usage ($)

With the current energy price of $0.12/kWh, leaving a table fan on for 24 hours a day can cost up to $0.86 per month, or $10.51 per year.

Daily cost example: 0.24 kWh x $0.12/kWh = $0.03 per day

Monthly cost example: 7.2 kWh x $0.12/kWh = $0.86 per month

Yearly cost example: 7.2 kWh x $0.12/kWh x 12 months = $10.32 per year

Money Saving Tips

Here are some money-saving tips for using a table fan:

  • Set a timer: Use a timer to turn off the fan when it’s not needed. For example, set it to turn off after four hours of use, so it doesn’t run all day.
  • Use it on low: Running the fan on low uses less energy than running it on high. Consider using the lowest setting that still provides adequate airflow.
  • Keep it clean: A dirty fan can’t run efficiently. Clean the blades regularly to ensure optimal performance.
  • Close doors and windows: Use the fan in a closed room. Opening doors and windows can let hot air in, which can cause the fan to consume more energy.
  • Use it in conjunction with an air conditioner: If you’re using an air conditioner, use the fan to circulate the cool air throughout the room. This can help to reduce the amount of time the air conditioner is running, which can save money on your energy bill.

In conclusion, a table fan may seem like a minor appliance in terms of energy consumption, but with continuous usage, it can significantly impact our wallets and the environment. By understanding the energy consumption and cost of usage, we can make informed decisions that save us money and help us conserve energy. Using the money-saving tips mentioned above can make a significant difference in reducing the cost of using a table fan.
