    The cost of running an electrical appliance depends on how much power it consumes, how long it's used, and the rate of electricity in your area. This calculator helps you easily calculate the cost of using any appliance over a specific period of time by inputting the power consumption, usage time, and electricity rate.

    How to Calculate Electrical Appliance Cost

    Follow these steps to calculate the cost of running an appliance:

    1. Enter the power consumption of the appliance in watts (usually listed on the label or user manual).
    2. Input the average number of hours the appliance is used each day.
    3. Optionally, enter the electricity cost per kilowatt-hour (kWh) for more accurate results, or use the default average rate.
    4. If you want to calculate for a specific number of days, enter that in the number of days used field.
    5. Click 'Calculate Appliance Cost' to see the total running cost of your appliance.

    Formula for Appliance Cost

    The formula to calculate the total cost is:

    Total Cost = (Power Consumption (Watts) × Usage Time (Hours) × Days Used × Cost Per kWh) / 1000

    This formula converts power consumption to kilowatt-hours (kWh), the unit used by most electric companies to bill customers.

    Example Calculation

    For example, if an appliance uses 500 watts for 4 hours per day, and the electricity rate is $0.12 per kWh, the cost for 30 days is:

    (500W × 4h × 30d × $0.12) / 1000 = $7.20

    This way, you can easily understand and plan your energy expenses.
