1. What is the Electricity Cost Calculation?

The electricity cost calculation determines how much you pay for the electricity you consume. It multiplies the amount of energy you use (in kilowatt-hours, kWh) by the price you pay per unit of energy (cost per kWh).

2. How Does the Calculator Work?

The calculator uses the simple formula:

\[ \text{Cost} = \text{kWh} \times \text{Cost per kWh} \]

Where:

Explanation: This calculation gives you the direct cost of electricity consumption before any additional fees or taxes that might be on your bill.
