Electricity Billing Estimator
How It Works
1. The user selects an appliance and inputs the required values for wattage, daily usage, and cost per kWh.
2. The tool calculates the daily energy consumption in kilowatt-hours (kWh) using the formula:
Daily Consumption (kWh) = Wattage (W) × Daily Usage (hours) / 1000
3. The monthly energy cost is then calculated as:
Monthly Cost ($) = Daily Consumption (kWh) × Cost per kWh ($) × 30
Benefits of the Estimator
- Energy Awareness: Understand which appliances consume the most energy.
- Cost Management: Budget for monthly electricity expenses.
- Sustainability: Make informed decisions to reduce energy consumption and carbon footprint.
This tool is ideal for integrating into websites, mobile apps, or home energy management systems to empower users with actionable insights about their electricity usage.
