Question: how much electricity does a dishwasher use in a month?
Answer: For a 1200-watt model and a load time of one hour, you use 1.2 kilowatt-hours (kWh), which is about 12 cents per load on a 10 cent per kWh electricity plan. If you run the appliance five days a week, you'll end up paying just $2.40 each month for basic electricity consumption.
