Understanding Your Meralco kWh Rate

Your Meralco bill isn't just a single charge; it is composed of various components including generation, transmission, distribution, and subsidies. Because these costs fluctuate monthly based on fuel prices and the exchange rate, your effective "price per kWh" changes every billing cycle.

How to use this calculator:

  • Total Bill Amount: Enter the "Total Amount Due" found on the upper right or bottom part of your Meralco statement.
  • Total Consumption: Look for the "kWh" value used for the current month.

Example Calculation:

If your total bill is ₱3,600 and your consumption is 300 kWh:
Calculation: 3,600 ÷ 300 = ₱12.00 per kWh.

What makes up the rate?

1. Generation Charge: The cost of electricity purchased from power suppliers (usually the largest part).
2. Transmission Charge: The cost of delivering electricity from power plants to Meralco's system.
3. Distribution Charge: The cost of delivering electricity from Meralco's system to your home.
4. Government Taxes: Includes VAT and local franchise taxes.
