Appliance Energy Cost Calculator
Estimate kWh usage and monthly or yearly electricity cost for appliances and electronics.
Use this appliance energy cost calculator to estimate how much electricity a device uses per day, per month, and per year. Enter the wattage, daily usage hours, active days per month, number of units, and your electricity rate to get a practical cost estimate.
This works well for air conditioners, refrigerators, fans, TVs, computers, space heaters, freezers, washing machines, and other household devices. It is useful when you want to compare habits, identify expensive appliances, or see whether a more efficient model could lower your bill.
The result shows daily, monthly, and yearly consumption in kWh, along with the estimated cost over time. That makes it easier to plan your home budget, review high-consumption devices, and understand the impact of changing how long something runs.
Use clear inputs to get a more useful result.
