Dehumidifiers: 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 504 ENERGY STAR certified dehumidifiers included in this analysis, the median appliance consumes approximately 362 kWh per year and costs an estimated $67 annually to operate, based on the U.S. national-average residential electricity rate. Annual operating costs across the field range from roughly $19 to $521, depending on the model's efficiency and capacity.

These figures are computed from each model's measured annual energy consumption applied uniformly to the national average rate, which allows for consistent comparison across the product category rather than relying on manufacturer estimates or regional variations. Operating cost represents only one dimension of the dehumidifier purchase decision; purchase price, capacity, and available features also play significant roles in the overall value proposition. From an energy perspective alone, however, a more efficient model can accumulate meaningful savings over the appliance's operational lifetime.

Actual operating costs will vary based on the buyer's local utility rate and patterns of use. This analysis presents specifications and cost estimates for comparison purposes and should not be construed as purchasing or installation guidance.
