Formula Used
Electric Consumption Formula
Total monthly consumption (kWh) = (Power Rating × Hours Used Daily × 30) ÷ 1000
Total monthly cost (MYR) = Total consumption × Tariff Rate
This formula calculates your monthly electricity consumption in kilowatt-hours and estimates the cost based on your selected tariff rate.
Worked Example
Suppose you have a 100W refrigerator running 24 hours daily and a 1500W air conditioner running 8 hours daily with a tariff rate of RM0.35 per kWh.
- Refrigerator consumption: (100 × 24 × 30) ÷ 1000 = 7.2 kWh
- Air conditioner consumption: (1500 × 8 × 30) ÷ 1000 = 36 kWh
- Total consumption: 7.2 + 36 = 43.2 kWh
- Total cost: 43.2 × 0.35 = RM15.12
This example shows how different appliances contribute to your total electricity usage and cost.
Interpreting Results
Your results will show:
- Total monthly electricity consumption in kilowatt-hours
- Estimated monthly cost based on your selected tariff rate
- A breakdown of consumption by appliance
- A comparison chart showing your usage against average Malaysian consumption
Use these results to identify energy-saving opportunities and make informed decisions about your electricity usage.
