1. What is an Electricity Cost Calculator?

Definition: This calculator estimates the cost of electricity based on usage in kilowatt-hours (kWh) and the current electricity rate.

Purpose: It helps UK households and businesses estimate their electricity bills and understand energy costs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:
