Quickly estimate your AC unit's operating cost with our free online calculator. Understand your air conditioner's energy consumption per hour, day, month, or year to manage electricity bills effectively and find ways to save.
Formula:
The core formula to calculate AC operating cost is based on power consumption, hours of use, and your electricity rate:
Energy (kWh) = (AC Power (Watts) × Hours Used) ÷ 1000
Cost = Energy (kWh) × Electricity Rate ($/kWh)
Where:
- AC Power (Watts): The typical power consumption of your AC unit. (e.g., a 12,000 BTU unit might be around 1000-1500 Watts)
- Hours Used: The total hours the AC operates in the desired period (e.g., per day).
- 1000: Conversion factor from Watts to Kilowatts.
- Electricity Rate ($/kWh): Your local electricity cost per kilowatt-hour, found on your utility bill.
