how much does it cost to operate a dishwasher daily
Multiply the wattage of your dishwasher (most models fall in a range between 1,200 and 2,400 watts) by the number of hours you run it each day. Divide this number by 1,000 to find the number of kilowatt-hours the dishwasher uses. Multiply this number by your cost per kilowatt-hour to come up with the daily cost of running your dishwasher. For example, suppose your dishwasher is rated at 1,800 watts, you run it for two hours a day and your electricity rate is 13 cents. Multiply 1,800 by 2 to get 3,600 watt-hours, or 3.6 kilowatt-hours. Multiply this figure by 13 cents, resulting in 46.8 cents. So it costs you just under 50 cents a day to run your dishwasher.
