Important assumption

Power draw is not always constant

Humidity level, set point, room temperature, fan speed, and compressor cycling affect real-world energy use.

State effect

Same usage, different electricity price

Lower-cost examples

Louisiana$15.26

Nevada$15.32

Utah$15.74

Higher-cost examples

Hawaii$57.60

California$40.33

Maine$38.89

How the estimate works

Energy use equals power in kilowatts multiplied by operating hours. The result in kilowatt-hours is multiplied by the selected electricity price. PowerCostAtlas starts with the latest available EIA residential state average and lets you replace it with the exact cents-per-kWh rate from your utility bill.

The estimate covers electricity consumption only. It does not add fixed monthly utility charges, taxes, demand charges, tiered pricing, or time-of-use adjustments.
