1. What is a Meralco Kilowatt per Hour Calculator?

Definition: This calculator estimates the electricity cost based on energy consumption in kilowatt-hours and the cost per kWh.

Purpose: It helps consumers estimate their Meralco electricity bills or compare costs for different appliances.

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 kilowatt-hour (₱/kWh)

Explanation: The energy consumption is multiplied by the cost per unit to get the total electricity cost.

3. Importance of Electricity Cost Calculation

Details: Accurate cost estimation helps with budgeting, identifying energy-hungry appliances, and making informed decisions about energy usage.

4. Using the Calculator

Tips: Enter the energy consumption in kWh and cost per kWh (default 11.5 ₱/kWh for 2025 estimate). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the current Meralco rate per kWh?
A: As of 2025 estimates, rates typically range between 10-13 ₱/kWh depending on consumption and other factors.

Q2: How do I find my energy consumption?
A: Check your appliance's wattage rating and multiply by hours used (1000W × 1 hour = 1 kWh).

Q3: Does this include all charges on my bill?
A: No, this calculates only the energy charge. Actual bills include additional fees like distribution charges.

Q4: Why does the rate vary?
A: Rates change monthly based on generation charges, foreign exchange, and other factors.

Q5: How can I reduce my electricity cost?
A: Use energy-efficient appliances, turn off unused devices, and consider shifting usage to off-peak hours.
