1. What is kW per Hour Cost Calculator?

Definition: This calculator estimates the electricity cost per hour based on power consumption in kW and the electricity rate in £/kWh.

Purpose: It helps UK residents and businesses estimate their electricity costs for appliances and equipment.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Hourly cost (£)
• \( P_{kW} \) — Power consumption (kilowatts)
• \( C_{kWh} \) — Electricity cost (£ per kilowatt-hour)

Explanation: The power consumption is multiplied by the electricity rate to get the hourly running cost.

3. Importance of Electricity Cost Calculation

Details: Understanding hourly costs helps with budgeting, comparing appliance efficiency, and managing energy consumption.

4. Using the Calculator

Tips: Enter the appliance's power consumption in kW and the electricity rate (default £0.28/kWh). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find my appliance's power consumption?
A: Check the manufacturer's specifications or look for the wattage rating on the appliance label (divide by 1000 to get kW).

Q2: Is £0.28/kWh the standard rate in the UK?
A: This was the average rate in 2023, but check your energy provider for current rates as prices fluctuate.

Q3: How do I calculate daily or monthly costs?
A: Multiply the hourly cost by the number of hours used per day/month.

Q4: Does this include standing charges?
A: No, this only calculates the consumption cost. Standing charges are fixed daily fees.

Q5: How accurate is this calculation?
A: It provides a good estimate, but actual costs may vary with usage patterns and tariff variations.
