1. What is an Electricity Cost Calculator?

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

Purpose: It helps homeowners, businesses, and energy professionals estimate electricity expenses for budgeting and energy management.

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 kWh)

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

3. Importance of Electricity Cost Calculation

Details: Accurate cost estimation helps with budgeting, comparing energy providers, and evaluating energy efficiency measures.

4. Using the Calculator

Tips: Enter the energy usage in kWh and electricity rate in $/kWh (default 0.12). All values must be > 0.
