1. What is the Energy Cost Calculator?

The Energy Cost Calculator estimates annual energy expenses based on electricity usage and price per kilowatt-hour. It helps consumers understand and budget for their energy consumption costs in the UK market.

2. How Does the Calculator Work?

The calculator uses the energy cost formula:

Where:

• \( kWh \) — Annual electricity usage in kilowatt-hours
• \( p \) — Price per kilowatt-hour in pence
• \( Cost \) — Total annual cost in pounds sterling

Explanation: The formula converts pence per kWh to pounds by dividing by 100, then multiplies by total consumption to get the annual cost.

3. Importance of Energy Cost Calculation

Details: Understanding energy costs helps households and businesses budget effectively, compare energy tariffs, identify potential savings, and make informed decisions about energy efficiency measures.

4. Using the Calculator

Tips: Enter your annual electricity usage in kWh (found on your energy bill) and the current price per kWh from your energy supplier. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find my annual kWh usage?
A: Check your latest energy bill or online account with your energy supplier. Most bills show annual consumption in kWh.

Q2: What is the average UK electricity price?
A: Prices vary by region and tariff, but typical rates range from 20-30 pence per kWh for domestic customers.

Q3: Does this include standing charges?
A: No, this calculator only estimates usage costs. Add daily standing charges separately for total bill calculation.

Q4: How accurate is this estimate?
A: Very accurate for fixed-rate tariffs. For variable tariffs, it provides a baseline estimate based on current rates.

Q5: Can I use this for business energy costs?
A: Yes, the calculation works for both domestic and commercial electricity consumption.
