Check your usage with our electricity calculator

Hi there! Wondering how much electricity you are using with individual appliances and where you can save on the bills? Using the electricity calculator below, it’s easy to figure out how much electricity you use and how much it costs based on how much power your appliances need.

Since every home is different, the best way to get accurate results is to change the usage for each appliance to match the exact one you have. Simply check the rating plates on each appliance, and write a list of not only the wattage of each unit but estimate how long each one is used daily, then apply it to our electricity calculator. Armed with this information, you are ready to begin your calculations. , then check each Happy calculating!

Welcome to our electricity calculator!

What it does

This electricity calculator tool is designed to help you understand how much it costs to run your appliances on a daily, weekly, monthly, and yearly basis. By entering the power of your appliance in watts, the amount of time it is used, and the energy price in dollars per kilowatt-hour (kWh), our electricity calculator will give you an estimate of how much it costs to run that appliance.

How energy units work

It’s important to understand how energy is measured and priced in order to fully utilize this tool. In the United States, energy is measured in kilowatt-hours (kWh). A kilowatt-hour is the amount of energy used by a 1,000-watt appliance for one hour. The energy price is typically measured in cents per kilowatt-hour (¢/kWh). To convert cents to dollars, divide the number of cents by 100. So, for example, if your energy price is 16 cents per kilowatt-hour, it is equivalent to $0.16 per kilowatt-hour. Electricity usage in the world in 2022 was 24,398 terawatt-hour (TWh), nearly three times the amount of consumption in 1981

Examples of average usage

To get an idea of the average energy usage of common appliances, here are some examples:

  • An air fryer typically uses 1,500 watts and is used for about 8 hours a day, which would cost about $0.48 per day, $3.36 per week, $14.56 per month, and $174.72 per year (based on an energy price of $0.16/kWh)
  • A 42-inch LED TV typically uses 58 watts and is used for about 4 hours a day, which would cost about $0.03 per day, $0.21 per week, $0.91 per month, and $10.92 per year (based on an energy price of $0.16/kWh)
  • A fridge/freezer typically uses 150 watts and is used 24/7, which would cost about $0.36 per day, $2.52 per week, $10.88 per month, and $130.56 per year (based on an energy price of $0.16/kWh)
  • A PlayStation 5 typically uses 160 watts and is used for about 4 hours a day, which would cost about $0.03 per day, $0.22 per week, $0.95 per month, and $11.40 per year (based on an energy price of $0.16/kWh) Please note that these are rough estimates, as actual usage and energy prices can vary greatly depending on individual circumstances.
  • Also, if you are unsure of the wattage of your appliances, you can check the label on the back or bottom of the appliance or consult the manufacturer’s website for further information and appliance ratings.

All electric appliances use electricity in one form or another. Usually, if the alliance is for use around the home, then the power source is mains-supplied electricity. Small appliances may use batteries, but note that batteries can be rechargeable or disposable.

These chargers require electricity too. Disposable battery life calculations are not the province of this calculator and should be calculated as purchases. Rechargeable batteries do come into play with regard to mains electricity usage, however. Remember that even if batteries are used in such appliances – some small vacuum cleaners or floor cleaning robots for example – these batteries need to be charged from a mains-powered charger.
