1. What is Cost per kWh?

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

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The total cost is divided by the total energy consumption 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 plans, and identifying potential savings opportunities.

4. Using the Calculator

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

Q2: Why is my cost per kWh different from the advertised rate?
A: Your actual cost includes taxes, fees, and other charges that may not be included in the base rate.

Q3: How can I use this to compare providers?
A: Calculate cost per kWh for each provider's plan using your actual or estimated usage to make accurate comparisons.

Q4: 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.
