1. What is an Electricity Bill Calculator?

Definition: This calculator estimates your electricity costs based on energy consumption and your utility's rate.

Purpose: It helps consumers understand and predict their electricity expenses for better budgeting.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Cost} \) — Total electricity cost (dollars)
• \( E \) — Energy consumption (kilowatt-hours)
• \( \text{Rate} \) — Electricity rate (dollars per kilowatt-hour)

Explanation: The energy consumed is multiplied by the rate charged per unit of energy.

3. Importance of Electricity Cost Calculation

Details: Understanding your electricity costs helps with budgeting, identifying high-usage appliances, and evaluating energy-saving measures.
