1. What is a Monthly Electricity Bill Calculator?

Definition: This calculator estimates the monthly electricity cost based on energy consumption and electricity rate.

Purpose: It helps homeowners and businesses predict and manage their electricity expenses.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Cost} \) — Total electricity cost ($)
• \( E_{\text{month}} \) — Monthly energy consumption (kWh)
• \( \text{Rate} \) — Electricity rate ($/kWh)

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

3. Importance of Electricity Cost Calculation
