1. What is a kW per Hour Cost Calculator?

Definition: This calculator estimates the cost of running electrical equipment based on its power consumption and electricity rate.

Purpose: It helps homeowners, businesses, and energy managers understand and predict electricity costs for various devices and systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The power consumption is multiplied by the electricity rate to determine the hourly operating cost.

3. Importance of kW Cost Calculation

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

4. Using the Calculator

Tips: Enter the device'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 my device's power consumption?
A: Check the device specifications (usually in watts - divide by 1000 to get kW) or use a power meter.

Q2: Where can I find my electricity rate?
A: Check your utility bill - it's typically listed as the cost per kWh.

Q3: Can I calculate daily/monthly costs with this?
A: Yes, multiply the hourly cost by hours used per day/month for extended period estimates.

Q4: Why use kW instead of watts?
A: Electricity is typically billed in kWh, so kW (1000 watts) is the standard unit for these calculations.

Q5: Does this include all electricity costs?
A: This calculates only energy consumption costs. Some bills may include additional fixed charges or fees.
