How we calculate this

Annual energy use (100 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 washer assumes 295 cycles a year, per the DOE test procedure (10 CFR 430 Subpart B, Appendix J2 (per §430.23)). It includes the energy to heat the wash water with an electric water heater. Full methodology.
