1. What is an Energy Cost Calculator?

Definition: This calculator estimates the monthly electricity cost based on energy usage in kilowatt-hours (kWh) and the electricity rate.

Purpose: It helps homeowners and businesses estimate their electricity expenses and budget accordingly.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Monthly Cost — Total electricity cost (currency)
• kWh — Energy consumption (kilowatt-hours)
• Rate — Electricity price per kWh (currency/kWh)

Explanation: The energy usage is multiplied by the electricity rate to calculate the total monthly cost.

3. Importance of Energy Cost Calculation

Details: Accurate energy cost estimation helps with budgeting, identifying potential savings, and comparing electricity plans.

4. Using the Calculator

Tips: Enter your monthly kWh usage (found on your electricity bill) and your electricity rate (default $0.12/kWh). All values must be > 0.

5. Frequently Asked Questions (FAQ)
