1. What is an Electricity Cost Calculator for South Africa?

Definition: This calculator estimates the electricity cost based on appliance power consumption, usage time, and the current electricity rate in South Africa.

Purpose: It helps households and businesses understand and predict their electricity expenses in South African Rand (ZAR).

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Cost} \) — Electricity cost (ZAR)
• \( P \) — Power consumption (watts)
• \( t \) — Usage time (hours)
• \( \text{Rate} \) — Electricity rate (ZAR per kWh)

Explanation: The formula converts watts to kilowatts (dividing by 1000) and multiplies by usage hours and the cost per kilowatt-hour.

3. Importance of Electricity Cost Calculation

Details: Accurate cost estimation helps with budgeting, identifying energy-hungry appliances, and making informed decisions about energy usage.

4. Using the Calculator

Tips: Enter the appliance's power in watts, usage time in hours, and electricity rate (default R2.50/kWh). All values must be > 0.
