Air Conditioner Running Cost Calculator
Estimate the running cost over a period using the air conditioner’s electrical input, daily runtime, electricity price and number of days.
Estimated result—
How it works
Energy = input kW × hours/day × days. Cost = energy × electricity rate.
Example
A 2.5 kW unit running 6 hours/day for 30 days at $0.35/kWh costs about $157.50 if it drew full input power continuously.
Useful things to know
- Inverter units usually modulate rather than draw maximum power continuously.
- The kW input figure is different from cooling capacity in kW.
- Room size, insulation, thermostat setting and outdoor temperature all affect usage.
