1. What is the UK Electricity Price Calculator?

Definition: This calculator estimates the cost of electricity usage based on appliance power, usage time, and current electricity rates.

Purpose: It helps UK residents understand and predict their electricity expenses for better budgeting and energy management.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Cost \) — Total electricity cost in pounds (£)
• \( P \) — Power consumption in watts (W)
• \( t \) — Usage time in hours
• \( Rate \) — Electricity rate in pounds per kilowatt-hour (£/kWh)

Explanation: The formula converts watts to kilowatts (dividing by 1000), then multiplies by hours and the rate to get total cost.

3. Importance of Electricity Cost Calculation

Details: Understanding electricity costs helps with budgeting, identifying energy-hungry appliances, and making informed decisions about energy usage.

4. Using the Calculator

Tips: Enter the appliance power in watts, usage time in hours, and electricity rate (default £0.34/kWh). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find my electricity rate?
A: Check your energy bill or contact your supplier. The default uses the UK average of £0.34/kWh (2023).

Q2: How do I find an appliance's power consumption?
A: Check the label, manual, or use a plug-in energy monitor. Typical examples: LED bulb (10W), laptop (50W), kettle (3000W).

Q3: Does this include standing charges?
A: No, this calculates usage costs only. Standing charges are fixed daily costs on your bill.

Q4: Can I calculate monthly/annual costs?
A: Yes, multiply daily usage by 30 for monthly or 365 for annual estimates.

Q5: How accurate is this calculator?
A: It provides estimates. Actual costs may vary due to tariff changes, VAT, or appliance efficiency variations.
