1. What is a kWh Calculator Cost UK?

Definition: This calculator estimates the cost of electricity based on energy usage in kilowatt-hours (kWh) and the cost per kWh in UK pounds.

Purpose: It helps households and businesses estimate their electricity bills or compare energy costs for different appliances.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Total cost (£)
• \( E_{kWh} \) — Energy consumption (kWh)
• \( C_{kWh} \) — Cost per kWh (£/kWh)

Explanation: The energy consumption is multiplied by the unit cost to calculate the total electricity cost.

3. Importance of kWh Cost Calculation

Details: Accurate cost estimation helps with budgeting, identifying energy-saving opportunities, and comparing energy tariffs.

4. Using the Calculator

Tips: Enter your energy usage in kWh and the cost per kWh (default £0.34, the UK average as of 2023). All values must be > 0.
