1. What is Cost per kW Hour Electricity Calculator?

Definition: This calculator estimates the hourly electricity cost based on power consumption and electricity rate.

Purpose: It helps homeowners, businesses, and energy managers understand and predict electricity expenses for appliances or systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Cost per hour (₱/hour or $/hour or £/hour)
• \( P_{kW} \) — Power consumption (kilowatts)
• \( C_{kWh} \) — Cost per kilowatt-hour (₱/kWh or $/kWh or £/kWh)

Explanation: The power consumption in kW is multiplied by the electricity rate to get the cost per hour of operation.

3. Importance of Electricity Cost Calculation

Details: Understanding electricity costs helps in budgeting, comparing appliance efficiency, and making informed energy decisions.

4. Using the Calculator

Tips: Enter the appliance's power consumption in kW and your electricity rate per kWh. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find an appliance's power consumption?
A: Check the nameplate or specification sheet, or use a wattmeter to measure actual consumption.

Q2: Where can I find my electricity rate?
A: Check your utility bill or contact your electricity provider.

Q3: Can I use this for monthly cost estimation?
A: Yes, multiply the hourly cost by the number of hours used per month.

Q4: Does this include all electricity charges?
A: This calculates only energy charges. Some utilities add fixed fees or demand charges not included here.

Q5: What's the difference between kW and kWh?
A: kW is power (rate of energy use), kWh is energy (power × time).
