Dishwashers: Annual Operating Cost

This is an estimate. Operating cost is an estimate, computed from each model's measured annual energy use at the EIA U.S. national-average residential electricity rate (18.56 ¢/kWh, March 2026). Your actual cost depends on your local utility rate and how you use the appliance. How we compute this.

Across the 728 ENERGY STAR certified dishwashers analyzed, the median appliance consumes approximately 239 kWh per year and costs an estimated $44 annually to operate, based on the U.S. national-average residential electricity rate. Operating costs for models in the field range from roughly $15 to $45 per year. This standardized calculation allows for direct comparison across models rather than relying on manufacturer labels alone.

Operating cost represents only one factor in the overall purchase decision. Purchase price, capacity, and available features also merit consideration. On energy efficiency alone, however, a more efficient model within this category can generate meaningful savings over its operational lifetime.

Actual operating costs vary based on local utility rates and individual usage patterns. This analysis presents specifications and cost comparisons; it does not constitute buying or installation guidance, and real-world expenses will depend on regional electricity pricing and how each appliance is used.
