Energy Consumption Calculator Meralco

Reviewed by Calculator Editorial Team

Calculate your energy consumption and costs using the MERALCO energy consumption calculator. This tool helps you estimate your electricity usage and costs based on your appliance consumption and electricity rates.

How to Use This Calculator

To use the energy consumption calculator, follow these steps:

  1. Enter the number of hours your appliances are used per day.
  2. Select the wattage of each appliance from the dropdown menu.
  3. Enter your electricity rate per kilowatt-hour (kWh).
  4. Click the "Calculate" button to see your estimated energy consumption and costs.

The calculator will display your daily, monthly, and annual energy consumption in kilowatt-hours (kWh) and the estimated cost based on your electricity rate.

Formula and Assumptions

The energy consumption is calculated using the following formula:

Energy Consumption Formula

Energy Consumption (kWh) = (Wattage × Hours Used per Day × Number of Days) / 1000

Cost = Energy Consumption × Electricity Rate

Assumptions:

  • 30 days in a month and 365 days in a year.
  • All appliances are used continuously during the specified hours.
  • Electricity rates are constant throughout the period.

Worked Example

Let's calculate the energy consumption for a refrigerator (150W) used 24 hours a day with an electricity rate of ₱10 per kWh.

  1. Energy Consumption (Daily) = (150 × 24 × 1) / 1000 = 3.6 kWh
  2. Energy Consumption (Monthly) = 3.6 × 30 = 108 kWh
  3. Energy Consumption (Annual) = 3.6 × 365 = 1,314 kWh
  4. Cost (Monthly) = 108 × 10 = ₱1,080
  5. Cost (Annual) = 1,314 × 10 = ₱13,140

Using the calculator with these values will give you the same results.

Interpreting Results

The results show your estimated energy consumption in kilowatt-hours (kWh) and the corresponding cost. Here's what each result means:

  • Daily Consumption: The amount of energy used each day.
  • Monthly Consumption: The total energy used over 30 days.
  • Annual Consumption: The total energy used over 365 days.
  • Monthly Cost: The estimated cost for the monthly energy consumption.
  • Annual Cost: The estimated cost for the annual energy consumption.

Use these results to understand your energy usage patterns and identify opportunities to reduce costs.
