1. What is a kWh to Cost Calculator?

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

Purpose: It helps homeowners, businesses, and energy professionals calculate electricity costs for budgeting and analysis.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Total cost ($ or £)
• \( E_{kWh} \) — Energy consumption (kilowatt-hours)
• \( C_{kWh} \) — Cost per kilowatt-hour ($/kWh or £/kWh)

Explanation: The energy consumption is multiplied by the cost per unit to determine the total electricity cost.

3. Importance of Energy Cost Calculation

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

4. Using the Calculator

Tips: Enter your energy consumption in kWh and the cost per kWh (default $0.12). All values must be > 0.
