About Appliance Run Cost
A plain answer to a plain question: what will this appliance add to my electric bill?
Product labels show one national cost. Electricity prices in the United States vary by more than three to one between states, so that single number is wrong for most people. This site redoes the math for each state.
We combine two public sources: the residential electricity price the U.S. Energy Information Administration publishes for each state, and the measured energy use of 7,844 models on the ENERGY STAR certified product lists. Details are on the sources page.
We are not engineers at a utility or a government agency. We do not sell appliances. The site pays for itself with ads and, in some cases, labeled partner links. That never changes the numbers.
