Aircon Power Consumption Calculator Singapore

Reviewed by Calculator Editorial Team

This aircon power consumption calculator helps you estimate your air conditioning unit's electricity usage in Singapore. By entering your aircon's specifications and usage patterns, you can calculate monthly energy costs and identify opportunities to reduce consumption.

How to Use This Calculator

To use this aircon power consumption calculator:

  1. Enter your air conditioning unit's power rating in watts (W)
  2. Select the number of hours you use the aircon per day
  3. Choose the number of days per month you use the aircon
  4. Click "Calculate" to see your estimated monthly power consumption

The calculator will display your estimated monthly electricity usage in kilowatt-hours (kWh) and the approximate cost based on Singapore's electricity tariffs.

Formula Used

Power Consumption Formula

Monthly Power Consumption (kWh) = (Power Rating × Hours per Day × Days per Month) ÷ 1000

Monthly Cost (SGD) = Monthly Power Consumption × Electricity Tariff

The calculator uses the standard formula for electrical power consumption, converting watts to kilowatt-hours by dividing by 1000. The electricity tariff used is based on Singapore's residential rates as of 2023.

Worked Example

Let's calculate the power consumption for a 1.5 kW (1500 W) aircon used 8 hours per day for 30 days:

Example Calculation

Monthly Power Consumption = (1500 W × 8 hours × 30 days) ÷ 1000 = 360 kWh

Monthly Cost = 360 kWh × 0.25 SGD/kWh = 90 SGD

This example shows that a 1.5 kW aircon running 8 hours daily would cost approximately 90 SGD per month based on current Singapore electricity rates.

Interpreting Results

The calculator provides two key results:

  • Monthly Power Consumption: Shows how much electricity your aircon uses in kilowatt-hours
  • Monthly Cost: Estimates your electricity bill based on current Singapore rates

These figures help you understand your aircon's energy impact and make informed decisions about usage patterns or potential upgrades to more efficient units.

Note

The calculator uses average Singapore electricity rates. Actual costs may vary based on your specific tariff plan and any additional charges.
