1. What is Cost per kWh Calculator?

Definition: This calculator determines the cost per kilowatt-hour (kWh) of electricity based on total cost and energy consumed.

Purpose: It helps consumers and businesses understand their electricity costs and compare different energy plans or usage periods.

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 consumed (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 identifying potential savings through energy efficiency.

4. Using the Calculator

Tips: Enter the total cost (from your electricity bill) and the total energy consumed (in kWh). Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find these values on my electricity bill?
A: The total cost is usually shown as "Amount Due" and energy consumed as "Usage" or "kWh consumed."

Q2: Why calculate cost per kWh when my bill shows it?
A: Bills often include fixed charges and taxes. This calculation gives you the true variable cost per unit of energy.

Q3: What's a typical cost per kWh?
A: Residential rates typically range from $0.10 to $0.30 per kWh, varying by location and provider.

Q4: Can I use this for solar power calculations?
A: Yes, it works for any electricity source when you know the total cost and energy produced/consumed.

Q5: How can I reduce my cost per kWh?
A: Use energy-efficient appliances, shift usage to off-peak times, or consider alternative energy sources.
