Online Energy Use Calculators
Our online energy use calculators allow you to estimate your energy use and cost to operate specific products. Determining how much electricity your appliances and home electronics use can help you understand how much money you are spending to use them.
Use the information below to estimate how much electricity an appliance is using and how much the electricity costs so you can decide whether to invest in a more energy-efficient appliance. Calculate your savings with Time-of-Use Rates, ENERGYSTAR appliances, and LED lights.

Standard-size dishwashers that have earned the ENERGY STAR® label are, on average, 12% more energy efficient than standard models. Select the type of dishwasher you own, and enter the number of loads you dry per week. Categorize the loads by on-peak and off-peak hours.
For added savings, make sure the dishes are scraped clean, run a full load, and use a water saver or quick cycle when appropriate. If you don’t mind drying your dishes or waiting until they air dry, you can turn off the heat dry cycle.
