How this is calculated

Annual energy use is the figure ENERGY STAR lists for this model under typical test conditions. It is not measured in your home.
Yearly cost = annual kWh × your rate. Monthly cost is the yearly cost divided by 12, a flat average. Five-year cost keeps the rate constant; prices will change.
Statewide averages are not your utility’s tariff. Use your bill’s rate for a closer number.
We do not estimate watts or hourly cost: the source data does not include them.
