It depends on wattage and hours of use. A 3,500-watt central AC run 6 hours a day for 30 days uses about 630 kWh, which at $0.16/kWh costs roughly $101 for the month. Use the calculator above for your own numbers.
Check the nameplate on the unit itself, the owner's manual, or the EnergyGuide label. If you only know the BTU rating and SEER, use our HVAC Operating Cost calculator instead.
Your rate in $/kWh is listed on your utility bill, usually per kilowatt-hour used. The U.S. average is roughly $0.16/kWh, but rates vary widely by state and utility.
This calculator provides a rough estimate based on the wattage and usage you enter. Actual appliance draw can vary with cycling, load, and outdoor conditions. Check your utility bill for the most accurate rate.
