Above figures are averages and will vary with individual living habits and unit efficiencies.

(Total Wattage x Estimated Hours Per Day Used x 30) / 1,000 = Estimated Monthly kWh

*Energy Saving models carrying a higher EER rating would be on the lower side of the estimated usage.
Older models tend to be toward the higher side.
