1. What is Cost per Kilowatt Hour Calculator?

Definition: This calculator determines the cost per unit of electrical energy based on total cost and energy consumption.

Purpose: It helps consumers and businesses understand their electricity costs and compare energy prices.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C_{kWh} \) — Cost per kilowatt-hour ($/kWh or £/kWh)
• \( C \) — Total cost ($ or £)
• \( E_{kWh} \) — Energy consumption (kWh)

Explanation: The total cost is divided by the total energy consumed to determine the cost per unit of energy.

3. Importance of Cost per kWh Calculation

Details: Understanding cost per kWh helps in budgeting, comparing electricity providers, and evaluating energy efficiency measures.

4. Using the Calculator

Tips: Enter the total cost in your currency and the total energy consumption in kilowatt-hours. All values must be > 0.
