- Energy Efficiency: Identify appliances consuming the most energy
- Budgeting: Plan electricity expenses for home or business
- Environmental Impact: Understand your carbon footprint from electricity usage
- Appliance Comparison: Compare energy efficiency of different devices
How to Use This Calculator
Using our electricity calculator is simple. Just follow these steps to get accurate cost estimates:
Step-by-Step Guide
- Select Currency: Choose between Indian Rupees (₹) or US Dollars ($)
- Enter Power Consumption: Input the wattage of your appliance (check the label or manual)
- Set Usage Time: Enter how many hours per day you use the appliance
- Specify Usage Days: Enter how many days per month the appliance is used
- Input Electricity Rate: Enter your local cost per kWh (check your electricity bill)
- Calculate: Click the calculate button to see your results
Calculation Formula
Daily Energy (kWh) = (Power in Watts × Hours per Day) ÷ 1000
Monthly Energy (kWh) = Daily Energy × Days per Month
Monthly Cost = Monthly Energy × Electricity Rate per kWh

Tips to Reduce Power Consumption
Home Energy Efficiency Tips
- Switch to LED bulbs: Use 75% less energy than incandescent bulbs
- Unplug electronics: Many devices consume power even when turned off (phantom load)
- Use smart power strips: Automatically cut power to devices not in use
- Maintain appliances: Clean filters and perform regular maintenance
- Optimize AC usage: Set thermostat 1-2 degrees higher and use ceiling fans
- Use natural light: Open curtains during daytime instead of using lights
- Upgrade to energy-efficient appliances: Look for ENERGY STAR rated products
- Insulate your home: Proper insulation reduces heating and cooling costs
