How this is calculated
- ENERGY STAR lists the power this model draws but no yearly figure. We estimate the annual energy use ourselves, assuming 8 hours a day at the average of its low-speed and high-speed power, with standby power for the other 16 hours, every day of the year. Your use will differ, so treat the cost as a guide.
- 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.
