Air conditioner electricity cost in United States

Cooling cost changes sharply with climate zone, equipment efficiency, thermostat setting, and the utility rate that applies in your state.

Rate used for the starting scenarioNo default loaded

Use the marginal residential energy rate from your utility. If summer pricing or time-of-use rates apply, compare the peak and off-peak portions separately.

Billing scopeUnited States

Enter the per-kWh energy charge from your utility bill. For time-of-use service, run separate peak and off-peak scenarios.

Live local scenario

Calculate with an editable rate.

Air conditioners cycle or modulate, so scheduled hours alone overstate energy use. The active-runtime input represents average compressor load across the operating window.

Active runtime accounts for cycling. Use 100% for devices that draw the rated power continuously.

A United States starting scenario

1.500 kW is multiplied by scheduled time and the 55% active-runtime assumption. The inputs are examples, not claims about every device. Replace each one with the label, meter reading, schedule, and tariff that apply to you.

AC cost = rated kW × scheduled hours × active-runtime share × tariff

The local calculation

AC cost = rated kW × scheduled hours × active-runtime share × tariff

The device model stays global. The currency, tariff scope, validity period, and billing cautions come from the United States data layer.

Before trusting the result

Three checks for United States

01

Use the unit’s electrical input, not its cooling-capacity rating.

02

Model humid or very hot weeks with a higher compressor duty cycle.

03

Keep utility fixed charges outside the appliance calculation.
