How this was checked
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. The full Dishwasher category page shows all 737 dishwashers ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
