AC Power Consumption Calculator
An air conditioner power consumption calculator helps you estimate the electricity cost for running your AC. Enter the tonnage or BTU of the AC unit, daily operating hours, and the cost per kilowatt-hour (kWh) to calculate daily, monthly, and yearly expenses. This tool is perfect for budgeting and saving on energy costs.
Air Conditioner Power Consumption Calculator
Calculate Your AC Power Consumption
- Ton/BTU: Enter the size of your AC in tons or BTU.
- kW: Automatically calculated based on tonnage or enter kW consumption.
- Daily Operating Hours: Input the average number of hours your AC runs daily.
- Rate per kWh: Enter the cost per kilowatt-hour charged by your electricity provider.
Results:
- Daily Cost: $0.24
- Monthly Cost: $7.20
- Yearly Cost: $86.40
The calculator assumes costs in USD for simplicity, but it can be adapted for any currency.

What is a Ton in Air Conditioning?
Air conditioners are often rated by their cooling capacity. One ton of cooling capacity equals the ability to remove 12,000 BTUs (British Thermal Units) per hour. This is roughly equivalent to 3.5 kW of cooling power. Common sizes range from 1 to 10 tons.
Common Ton/BTU to kW Conversion Chart:
| Ton | BTU | kW |
|---|---|---|
| 1 | 12,000 | 1.2 |
| 1.5 | 18,000 | 1.8 |
| 2 | 24,000 | 2.4 |
| 2.5 | 30,000 | 3.0 |
| 3 | 36,000 | 3.6 |
Frequently Asked Questions (FAQs)
1. How do I calculate the cost of running a 1-ton AC for 3 hours daily?
- A 1-ton AC consumes about 1.2 kW.
- For 3 hours, it uses 3.6 kWh (1.2 kW * 3 hours).
- At $0.05/kWh, the daily cost is $0.18.
2. What’s the cost of running a 1.5-ton AC for 5 hours daily at $0.1/kWh?
- A 1.5-ton AC consumes 1.8 kW.
- In 5 hours, it uses 9 kWh (1.8 kW * 5 hours).
- The cost is $0.90 (9 kWh * $0.1).
3. How much does it cost to run a 2-ton AC for 3 hours daily at $0.2/kWh?
- A 2-ton AC consumes 2.4 kW.
- For 3 hours, it uses 7.2 kWh.
- At $0.2/kWh, the daily cost is $1.44.
4. What is an inverter AC? Inverter ACs use advanced technology that adjusts the compressor speed based on the cooling demand, making them more energy-efficient than non-inverter ACs. They save up to 40% on energy consumption.
5. Are there specific calculators for inverter ACs? No, but inverter ACs are typically 40% more efficient than non-inverter units. Use this general calculator and reduce the calculated cost by 40% to estimate for inverter models.
Inverter vs Traditional ACs
Traditional Non-Inverter ACs: These units frequently turn the compressor on and off, leading to higher power consumption and temperature fluctuations.
Inverter ACs: They start at high RPMs to quickly reach the desired temperature and then reduce power consumption by adjusting the compressor speed. This results in smoother cooling, reduced energy use, and longer lifespan of the unit.

EER Rating of Air Conditioners
The Energy Efficiency Ratio (EER) measures the efficiency of room air conditioners. It’s the ratio of cooling capacity (BTUs per hour) to power input (watts). The higher the EER, the more efficient the AC.
