1. What is Cost per Kilowatt Hour?

Cost per kilowatt hour (kWh) is a standard measure of electricity pricing that represents how much you pay for each unit of electrical energy consumed. It's the fundamental metric for comparing electricity rates.

2. How Does the Calculator Work?

The calculator uses the simple equation:

Where:

• \( Cost_{kWh} \) — Cost per kilowatt hour ($/kWh)
• \( Total\ Cost \) — Total electricity cost ($)
• \( kWh \) — Total kilowatt hours consumed (kWh)

Explanation: This calculation divides your total electricity bill by the total energy consumed to determine the rate you're paying per unit of electricity.

3. Importance of Cost per kWh Calculation

Details: Knowing your cost per kWh helps you compare electricity plans, understand your energy expenses, and make informed decisions about energy efficiency measures.

4. Using the Calculator

Tips: Enter your total electricity cost in dollars and your total energy consumption in kilowatt hours. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find these numbers on my bill?
A: Your total cost is usually labeled "Amount Due" and kWh usage is typically listed as "Energy Charge" or similar.

Q2: What's a typical cost per kWh?
A: Residential rates in the US average about $0.10-$0.20 per kWh, but vary widely by location and provider.

Q3: Does this include all charges on my bill?
A: For most accurate comparison, use the total bill amount including all fees and taxes.

Q4: How can I reduce my cost per kWh?
A: Consider switching plans/providers, using energy during off-peak hours, or installing energy-efficient appliances.

Q5: Is time-of-use pricing accounted for?
A: This gives an average rate. For time-varying rates, you may need more detailed calculations.
