1. What is an Electricity Cost per kWh Calculator?

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

Purpose: It helps homeowners, businesses, and energy-conscious individuals understand and predict their electricity expenses.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

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

3. Importance of Electricity Cost Calculation

Details: Understanding electricity costs helps with budgeting, comparing energy providers, and identifying potential savings through energy efficiency.

4. Using the Calculator

Tips: Enter your energy consumption in kWh and the cost per kWh from your electricity bill. All values must be > 0.

5. Frequently Asked Questions (FAQ)
