How this air conditioner electricity cost calculator works
Air-conditioner electricity use is input watts ÷ 1,000 × average run hours per day. Monthly and annual kWh are then multiplied by your electricity price.
How to use it
- Power draw. Enter the value in W.
- Hours used per day. Enter the value in hours.
- Days used per month. Enter the value in days.
- Electricity rate. Enter the value in $/kWh.
- Request the result. Add your email, then select “Email & show my result.”
What to do with the number
Air conditioners cycle with weather and thermostat demand, so average daily runtime matters more than the maximum hours the unit is switched on. Use a hot-weather utility bill or a smart energy monitor to estimate realistic compressor runtime instead of assuming the unit draws full power all day.
Planning estimate
Use this result as a starting point, not a guarantee. Product specifications, site conditions, manufacturer guidance, local codes, taxes, labor, tolerances, and rounding can change the real requirement or cost.
