1. What is an Electricity Cost Calculator?

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

Purpose: It helps homeowners and businesses understand and predict their electricity expenses.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

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

3. Importance of Electricity Cost Calculation

Details: Understanding electricity costs helps with budgeting, identifying energy-saving opportunities, and comparing utility providers.

4. Using the Calculator

Tips: Enter your energy consumption in kWh and the cost per kWh (default $0.12). All values must be > 0.

5. Frequently Asked Questions (FAQ)
