1. What is an Electric Consumption Calculator for Philippines?

Definition: This calculator estimates electricity usage in kilowatt-hours (kWh) based on appliance power and usage time.

Purpose: It helps Filipino households and businesses estimate their electricity consumption and potential Meralco bill costs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E \) — Electricity consumption (kWh)
• \( P \) — Power consumption (watts)
• \( t \) — Usage time (hours)

Explanation: The formula converts watt-hours to kilowatt-hours by dividing by 1000, which is the standard unit for electricity billing.

3. Importance of Electricity Calculation

Details: Understanding electricity consumption helps in budgeting, energy conservation, and identifying high-consumption appliances.

4. Using the Calculator

Tips: Enter the appliance's power rating in watts (found on the label) and your daily usage time in hours. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my appliance's power rating?
A: Check the label or manual for wattage (W). If only amps (A) are listed, multiply by 220V (Philippine voltage).

Q2: How does this relate to my Meralco bill?
A: Meralco charges per kWh. Multiply the result by your current rate (around ₱9-12/kWh) to estimate cost.

Q3: What's a typical consumption for appliances?
A: Refrigerator: 100-400W, AC: 1000-2000W, LED TV: 50-100W, Fan: 50-100W.

Q4: Should I use daily or monthly hours?
A: For daily cost, use hours/day. For monthly, multiply daily hours by 30 or track actual monthly usage.

Q5: Does this include all Meralco charges?
A: No, this calculates only consumption. Bills include generation charge, distribution charge, taxes, etc.
