1. What is a kWh Calculator for Meralco?

Definition: This calculator estimates the energy consumption in kilowatt-hours (kWh) based on power consumption in kilowatts (kW) and usage time in hours.

Purpose: It helps Philippine consumers estimate their electricity bills from Meralco (Manila Electric Company) by calculating energy usage.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E \) — Energy consumption (kWh)
• \( P \) — Power consumption (kW)
• \( t \) — Usage time (hours)

Explanation: The power consumption is multiplied by the usage time to get total energy consumed.

3. Importance of kWh Calculation

Details: Meralco bills customers based on kWh usage. Understanding energy consumption helps manage electricity costs and identify power-hungry appliances.

4. Using the Calculator

Tips: Enter the appliance's power consumption in kW and the duration of use in hours. For appliances rated in watts, divide by 1000 to get kW.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my appliance's power consumption?
A: Check the appliance's specification plate or manual. It's usually listed in watts (W) or kilowatts (kW).

Q2: What's the average kWh consumption for Philippine households?
A: Typical Meralco customers use 200-400 kWh per month, but this varies by household size and appliance usage.

Q3: How does this relate to my Meralco bill?
A: Meralco charges per kWh used. Multiply the result by Meralco's current rate (around ₱8-12 per kWh) to estimate cost.

Q4: Should I use peak or off-peak rates?
A: This calculator provides total consumption. Meralco's time-of-use rates would require separate calculations for peak/off-peak periods.

Q5: Does this include all Meralco charges?
A: No, this only calculates energy consumption. Your actual bill includes generation charges, transmission fees, taxes, and other components.
