1. What is a Meralco kWh Rate Calculator?

Definition: This calculator estimates electricity costs based on energy consumption in kilowatt-hours (kWh) and the current Meralco rate per kWh.

Purpose: It helps consumers and businesses estimate their electricity bills based on their power consumption.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Total cost (Philippine Pesos)
• \( E_{kWh} \) — Energy consumption (kilowatt-hours)
• \( C_{kWh} \) — Cost per kWh (₱/kWh)

Explanation: The energy consumption is multiplied by the rate per kWh to calculate the total electricity cost.

3. Importance of Electricity Cost Calculation

Details: Understanding electricity costs helps with budgeting, energy conservation efforts, and comparing appliance efficiency.

4. Using the Calculator

Tips: Enter your energy consumption in kWh and the current Meralco rate (default 11.0 ₱/kWh). All values must be > 0.

5. Frequently Asked Questions (FAQ)
