How Much Does Each Appliance Cost to Run?

Appliance running cost by hour, day, month and year

Direct answer: the guide's 1,350 W example used 0.37 hours/day at the EIA June 2026 residential average of $0.1834/kWh, or about $0.09/day. Formula: W ÷ 1,000 × hours × rate. This is a source-backed example checked 2026-09-15, not a product guarantee.

The rate is an editable starting point; replace it with your bill. The EIA table is June 2026 residential average, 18.34¢/kWh, preliminary. View EIA source (checked 2026-09-15).

    How to read the result

    The model covers electricity only: convert watts to kW, then multiply by hours and the rate you enter. Month means 30 days and year means 365 days; fixed charges, repairs, consumables and purchase cost are outside the result. Use the marginal rate for the added load rather than allocating your whole household bill.

    How this is calculated

    Method

    This page converts watts to kilowatts, then applies the visible hours and electricity rate to estimate marginal energy cost.

    Formula

    W ÷ 1,000 × hours × electricity rate

    Frequently asked questions

    What is the appliance electricity formula?
    Convert watts to kilowatts, then multiply by hours used and your electricity rate: W ÷ 1,000 × hours × rate. The monthly and annual views use 30 and 365 days.
    Are the wattage defaults product averages?
    No. They are traceable anchors from the repo guide library, often a worked example or measured routine. Replace them with the nameplate, smart-plug reading or plug-meter result for your model.
    Can I compare different appliances fairly?
    Yes, as a planning comparison when you use the same rate. The ranking uses each row’s default hours; change the selected appliance hours for your household and treat the result as an estimate.
    Does the result include the whole electricity bill?
    No. It estimates the marginal energy charge only. Fixed household charges, repairs, consumables, purchase cost and maintenance are separate.
