Estimate the monthly and yearly cost of running an appliance.
To find running cost, convert the wattage and usage into kilowatt-hours, then multiply by the electricity rate. Running the appliance every day compounds into a clear monthly figure. Many households underestimate how much high-wattage appliances cost, so converting watts to a monthly bill makes wasteful habits visible.
