Electric Consumption Calculator Singapore

Reviewed by Calculator Editorial Team

Understand your electric consumption in Singapore with this calculator. Calculate your monthly usage, costs, and environmental impact based on your appliance usage patterns and Singapore's electricity rates.

How to Use This Calculator

To calculate your electric consumption in Singapore:

  1. Enter the number of hours you use each appliance daily
  2. Select the power rating for each appliance
  3. Click "Calculate" to see your results
  4. Review the breakdown of your consumption and costs

The calculator uses Singapore's standard electricity rates and assumes a 30-day month. You can adjust these assumptions if needed.

Formula Used

The calculator uses the following formula to calculate electric consumption:

Electric Consumption (kWh) = (Hours per day × Power Rating (W) ÷ 1000) × Number of Days

For cost calculation:

Electric Cost (SGD) = Electric Consumption (kWh) × Electricity Rate (SGD/kWh)

Singapore's current electricity rate is approximately 0.25 SGD per kWh for residential customers.

Worked Example

Let's calculate the consumption for a typical Singapore household:

  • Air conditioner: 8 hours/day, 1500W
  • Refrigerator: 24 hours/day, 200W
  • Television: 4 hours/day, 100W
  • Laptop: 6 hours/day, 60W

Using the formula:

Air conditioner: (8 × 1500 ÷ 1000) × 30 = 360 kWh Refrigerator: (24 × 200 ÷ 1000) × 30 = 144 kWh Television: (4 × 100 ÷ 1000) × 30 = 12 kWh Laptop: (6 × 60 ÷ 1000) × 30 = 10.8 kWh Total: 360 + 144 + 12 + 10.8 = 526.8 kWh Cost: 526.8 × 0.25 = 131.7 SGD

This example shows a typical household might consume about 526.8 kWh per month, costing approximately 131.7 SGD.

Interpreting Results

Your electric consumption results show:

  • Total kWh: Your total electricity usage in kilowatt-hours
  • Estimated cost: Based on Singapore's current residential rates
  • CO₂ emissions: Estimated carbon footprint based on Singapore's grid mix

Use these results to:

  • Identify high-consumption appliances
  • Compare with neighbors or similar households
  • Plan energy-saving measures
  • Understand your environmental impact

Note: These calculations are estimates. Actual consumption may vary based on factors like weather conditions and appliance efficiency.
