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
Electricity is billed in kilowatt-hours (kWh): a 1,000-watt appliance running for one hour uses 1 kWh. Convert the cents-per-kWh figure on your bill to dollars before entering it; for example, 18 cents is $0.18. The EIA reports a 2025 U.S. residential average of 17.30 cents/kWh, but local rates vary substantially.

Worked examples at $0.18/kWh
These examples show the calculation rather than claiming a universal usage pattern. Replace the wattage, daily time and tariff with your own figures:
- A 1,500-watt air fryer used for 30 minutes a day consumes 0.75 kWh and costs about $0.14 per day, $0.95 per week, $4.05 per 30-day month and $49.28 per year at $0.18/kWh
- A 58-watt television used for four hours a day consumes 0.232 kWh and costs about $0.04 per day, $0.29 per week, $1.25 per 30-day month and $15.24 per year at $0.18/kWh
- For a fridge/freezer, use the annual kWh figure on its EnergyGuide label where possible. Multiplying its maximum wattage by 24 hours usually overstates consumption because the compressor cycles on and off
- A 160-watt games console used for four hours a day consumes 0.64 kWh and costs about $0.12 per day, $0.81 per week, $3.46 per 30-day month and $42.05 per year at $0.18/kWh. Actual draw varies by activity and power-saving settings.
- 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.
