How we calculate this
Annual energy use (133 kWh a year) is the figure the manufacturer filed for this model with the EPA, in the ENERGY STAR certified product database. Running cost is that figure multiplied by a state's average residential electricity price from the U.S. Energy Information Administration (12-month average through July 2026, average revenue per kWh).
The annual figure for a dryer assumes 283 cycles a year, per the DOE test procedure (10 CFR 430 Subpart B, Appendix D1/D2). Full methodology.
