Free electricity calculator to estimate electricity usage as well as cost based on the power requirements and usage of appliances.
The Energy Consumption Calculator evaluates the energy usage of devices and appliances based on their wattage and operating hours. By inputting these details, users receive an estimate of their daily, monthly, and yearly energy consumption.
Enter the type of appliance or device (e.g., refrigerator, air conditioner). Enter the power rating in watts or kilowatts. Enter the hours of use per day. Click the "Calculate Energy Consumption" button to see the estimated energy consumption per day in kilowatt-hours (kWh).
Energy Consumption Calculation: Daily Energy Consumption (kWh) = Power Rating (W) × Usage Time (h) / 1000. For a 150W refrigerator: Daily Consumption: 150W × 24h / 1000 = 3.6 kWh; Monthly Consumption: 3.6 kWh × 30 days = 108 kWh; Yearly Consumption: 3.6 kWh × 365 days = 1,314 kWh
