Do you ever open your Meralco bill and wonder where all that energy went? You're not alone. Understanding how electricity is billed can help you manage your consumption and even plan for energy-saving upgrades like solar panels. Let’s walk through how to compute your electricity cost — step by step.



🔢 The Simple Formula

To estimate how much a specific appliance is costing you each month, use this formula:

Electricity Cost = Wattage × Hours Used per Day × Number of Days × Meralco Rate ÷ 1000

Note:Meralco rates typically range between ₱11 to ₱13 per kWh depending on your area and usage tier. For this example, we’ll use ₱12/kWh.


🧮 Real-World Examples for Filipino Homes

Here’s a breakdown of common household appliances and how much they could be costing you each month:

Appliance

Wattage

Usage (hrs/day)

Estimated Monthly Cost (₱)

LED TV

100W

5 hrs

₱180

Electric Fan

70W

10 hrs

₱252

1HP Air Conditioner

746W

8 hrs

₱2,147

Rice Cooker

1 hr

₱252

Laptop

60W

8 hrs

₱172

Washing Machine

500W

1 hr, 3x/week

₱72

These small numbers add up, especially when appliances are used simultaneously or during peak hours.


⚡ Why Understanding This Matters

When you’re aware of how much electricity each appliance consumes, it becomes easier to make smarter energy choices. You may opt to reduce your usage, upgrade to inverter appliances, or even take the leap toward renewable energy.


✅ Energy-Saving Tips for Every Filipino Home

  • Unplug unused appliances – standby power can still cost you.

  • Switch to LED bulbs – they last longer and use less electricity.

  • Clean your aircon filters – dirty filters force your unit to work harder.

  • Use appliances during non-peak hours – Meralco’s peak times may cost you more.

  • Insulate your home – especially your roof, to reduce heat buildup.


☀️ Go Solar for Long-Term Savings

If you’re serious about cutting your Meralco bill, solar energy is a smart investment. With systems that can be customized for your home or business, you can offset a large portion of your bill and protect yourself from rising electricity rates.
