1. What is the Cost of a kWh of Electricity Calculator?

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

Purpose: It helps homeowners, businesses, and energy professionals calculate electricity expenses for budgeting and cost analysis.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

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

3. Importance of Electricity Cost Calculation

Details: Understanding electricity costs helps with budgeting, comparing energy providers, and evaluating energy efficiency measures.

4. Using the Calculator

Tips: Enter the energy consumption in kWh and the cost per kWh (default $0.12). Energy must be > 0, cost can be 0 for free electricity.
