1. What is Cost per kWh?

Cost per kilowatt-hour (kWh) is a measure of electricity price that represents how much you pay for each unit of energy consumed. It's the standard unit for comparing electricity rates and calculating energy expenses.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Total Cost — Your electricity bill amount in dollars
• Total Energy Used — Your electricity consumption in kilowatt-hours

Explanation: This calculation divides your total electricity cost by the amount of energy you've used to determine the price per unit of energy.

3. Importance of Cost per kWh Calculation

Details: Knowing your cost per kWh helps you understand your electricity rate, compare utility providers, estimate future bills, and evaluate the cost-effectiveness of energy efficiency measures.

4. Using the Calculator

Tips: Enter your total electricity cost (from your bill) and your total energy usage in kWh (also from your bill). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find these numbers on my bill?
A: Look for "total amount due" or "current charges" for cost, and "kilowatt-hours used" or "kWh" for energy usage.

Q2: What's the average cost per kWh?
A: In the U.S., the average is about $0.13-$0.15 per kWh, but varies by location and provider.

Q3: Why is my calculated rate different from my advertised rate?
A: Your bill includes additional fees and taxes beyond the base electricity rate.

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

Q5: Does this work for both residential and commercial bills?
A: Yes, the calculation is the same, though commercial rates often have more complex pricing structures.
