Last updated April 11, 2023

Don’t you just hate getting shocked by how much your electricity bill has increased compared to previous months? Now that it's summer once again, your electric consumption is probably higher than before. Here’s a guide on how to compute your Meralco bill to avoid bill shock. 

Breaking Down Your Meralco Bill Payment

According to Meralco, only 17.5% of your total bill[1] goes to the company. This means that if your total bill for March 2023 is ₱3,000, only ₱510 of this amount goes to Meralco.

So where does the rest of your payment go? Here is Meralco's breakdown of charges.

📌 Generation Charge: 55%

The Generation Charge goes to paying Meralco’s electricity suppliers, like the Independent Power Producers (IPPs) and other power producers. 

📌 Transmission Charge: 10.1%

The transmission charge is also known as the delivery charge. When Meralco buys electricity from its power suppliers, it pays 10.1% for the cost of delivery for the electricity to reach Meralco’s distribution system. The transmission charge goes to the National Grid Corporation of the Philippines (NGCP), which is the provider of transmission services. 

📌 Distribution Charge: 17.5%

Meralco takes 17.5% of your monthly bill to cover the cost of distribution, which pays for the construction, development, operation, and maintenance of the distribution system. This distribution system is used in delivering electricity from high-voltage transmission grids to end-users. 

📌 Taxes: 11.7%

This covers local franchise tax, Value Added Tax, Tax Recovery Adjustment Charge (TRAC), and Missionary Electrification Charge, just to name a few. 

📌 Other Charges: 5.7%

System loss and Feed-in-Tariff Allowance compose other payables covered by your Meralco bill. A portion of your payment also goes to subsidies provided as a lifeline for low-income customers and senior citizens through a discount of 5% on their bills.

 

3 Factors Affecting Your Electricity Bill

According to Meralco, a lot of factors contribute to the increased power rates. Below are other factors you should be aware of.

👉 High Heat Index and Increased Demand

Heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.[2] The highest heat index recorded so far this year is 47°C in San Jose, Occidental Mindoro and Butuan City, Agusan del Norte.[3]

When the heat index is high, appliances at home are forced to work harder and longer to cope with the temperature. In contrast, during rainy months, the temperature is colder. You won't feel the need to use the air conditioner or electric fan as much, resulting in lower electricity consumption. 

👉 Month-on-Month Rate and Consumption Increase

If you hate surprises like a sudden and significant spike in your Meralco bill, then you need to prepare your budget. Before your next Meralco bill arrives, know how to compute your electric consumption for the month based on Meralco’s announced rate increase. This will help you correctly compute your potential bill for the month.

Meralco raised its overall rate by ₱0.55 per kilowatt hour (kWh) for March 2023, bringing it to ₱11.43/kWh. This means a typical household consuming 200 kWh per month could expect an increase of about ₱109 in its electric bill.[4]

👉 Type of Appliance

If you want to learn how to compute your Meralco bill, you should know that the type, quantity, and quality of your appliances can greatly affect your consumption rates. 

How to Compute Electric Consumption of an Appliance 

To compute how many kWh an appliance uses, follow this formula:

kWh per appliance = Wattage/1,000 x number of hours the appliance is used

For a 1HP, 950-watt, non-inverter air conditioner, here’s a sample computation. 

  • 950 watts /1,000 = 0.95 x 10 hours = 9.5 kWh
  • 9.5 kWh x ₱8.9071/kWh = ₱84.5595
Appliance Wattage Cost Per Hour Cost Per Day if 10 Hrs/Day Cost Per Week Rate Per Month
Air Conditioner (Non-Inverter, Window Type, 1HP) 950 8.46 84.60 592.20 2,368.80
Regular Stand Fan 150 1.50 15.00 105.00 42.00

Quantity and Duration of Use

If you’re using air conditioners instead of electric fans, your electric consumption will be higher. However, if you’re using more than one electric fan for extended hours, then your electricity consumption will be the same as when you’re using an aircon. 

Quality of Appliances in Use

Did you know that an older refrigerator consumes 66% more electricity[5] than a newer model? Every appliance loses its energy efficiency as it ages.

If you know which appliances you’re using the most at home and their condition, you’ll have a good idea of how much your bill would be each month. 

If you're a Taylor Swift fan (or your kids are), you've surely heard the iconic song "All Too Well." While Taylor makes dancing around the kitchen in the refrigerator lightsound romantic, Meralco also reminded us that doing so would cost ₱9.79/day.

Learn How to Read Your Electric Meter

how to compute Meralco bill - reading an electric meter

Your electric meter plays a critical role in learning how to compute Meralco bill. Meralco uses your meter readings for the previous month and the present month to determine your total electricity usage in kilowatts per hour (kWh), which is the basis for computing your monthly bill.

Why bother reading your meter yourself? Even if Meralco has trained meter readers who can do the job accurately, being able to read your electric meter lets you keep track of your power consumption to ensure that your household isn't consuming too much electricity.

If your electric meter has a small digital screen display, finding out your electricity consumption is pretty simple and straightforward. Just read the numbers from left to right.

You have an electromechanical meter if it has four dials instead of a digital numerical display. It looks more complicated than a digital meter because its dials move in opposite directions (two moving clockwise and the other two moving counter-clockwise).

But it's actually easy to read. Simply take note of the number that each dial is pointing at, beginning from the rightmost dial to the leftmost dial.

Record your reading this month and subtract it from your reading for the following month. The resulting kWh may not match the actual kWh reflected on your next Meralco bill (as Meralco's meter reading date may be different from yours), but it at least gives you an estimate of your monthly power consumption.

 

How to Compute Meralco Bill 

Many factors affect electricity prices, and they change from time to time. Also, the monthly bill consists of several electricity charges that Meralco calculates using various percentages. A Meralco bill might be too complicated for an average consumer to comprehend.

So if you're trying to figure out how to compute Meralco bill, know that it's impossible to do on your own. You won't know in advance the exact amount to pay for a particular month until your bill arrives.

However, if you're aiming to save on your electric bill, you can compute the cost of using each appliance and electronic device in your home.

How to Compute Electric Consumption in the Philippines

👉 Manual Computation

Follow these steps to manually estimate the electricity consumption of a specific device:

  1. Get your device's wattage. Find this information at the bottom or back of the device, or in the owner's manual. You may also try searching for the device's technical specs online.
  2. Compute the watts the device consumes daily. Multiply the wattage by the average number of hours the device is used per day. Let's say you use a 100-watt electric fan for 10 hours per day. Multiplying 100 watts by 10 hours will result in 1,000 watt-hours—that's how much your electric fan consumes in a day.
  3. Convert watt-hours to kilowatts. Divide the device's watt-hours by 1,000 to convert it to kilowatts, which is the unit of measurement used in a Meralco bill. In the example above, 1,000 watt-hours divided by 1,000 is equal to 1 kWh consumption per day.
  4. Compute the device's monthly power consumption. Multiply your device's daily kWh by 30 days to determine how much it consumes per month. The monthly usage for an electric fan consuming 1 kWh daily is 30 kWh.

List down the monthly electricity usage of your appliances and devices and rank them from highest to lowest. This will let you know which ones consume the most electricity and should be used less and unplugged more often.

👉 Online Computation Using the Meralco Calculator

The formula discussed above is a just simplified approach to estimating your monthly electricity consumption. If you want to know the cost of using your home appliances and devices, use an online calculator that will compute it for you. You may use either the Meralco Appliance Calculator or Wattmatters Calculator.

How to Use Meralco Appliance Calculator

The best way to compute electric consumption is to use the Meralco calculator, which is currently available on the Meralco Mobile app. You may access the Meralco Appliance Calculator without having to register for an account or logging in (if you already have an account).

After installing the Meralco mobile app, you can start computing the electricity cost of your appliances. Here's how:

  1. Tap on the Appliance Calculator icon.
  2. Enter your average monthly bill amount. Just estimate the average based on your latest Meralco billing statements.
  3. Pick an appliance from the drop-down menu. Tap the Set button. The app will show you the appliance's wattage.
  4. Choose the number of hours you use the appliance in a day. Select also the number of days in a week and weeks in a month the appliance is used.
  5. Tap the Calculate button. You'll see the electricity cost per hour, day, week, and month of your appliance.

Using the Meralco Mobile app, you can compute only one appliance at a time. You have to repeat the entire procedure if you want to compute your electricity cost for other appliances.

 

👉 Online Computation Using the Wattmatters Calculator
