How much does a dehumidifier cost to run?
A dehumidifier's humidistat cycles the compressor as moisture changes. Room conditions and the humidity target can move annual cost substantially.

kW × effective runtime × rate. Effective runtime = hours/day × duty cycle.
Baseline vs scenario
Compare two annual energy-use estimates.
Old vs new appliance payback
Use annual kWh for both models. Leave rebate at $0 unless you have a confirmed amount.
Simple payback = net upfront cost ÷ annual electricity-cost savings. Excludes financing, maintenance, rate changes and time value of money.

How your rate changes the cost
Same appliance inputs, using May 2026 EIA residential averages.
Make the estimate more accurate
- Base hours on the damp season if use is seasonal.
- Clean the filter and allow airflow.
- A continuous drain prevents interruptions but does not directly reduce power.
Presets are estimates. Use your model label, an EnergyGuide annual-kWh figure or a safe meter reading when available. Compare old and new appliance payback.
