Understanding Appliance Energy Consumption
Have you ever wondered why your electricity bill spiked during the summer or winter months? Appliances like Air Conditioners, Heaters, and Geysers consume massive amounts of power. Our Electricity Cost Calculator helps you isolate individual appliances to see exactly how much money they are drawing from your wallet every month.
What is a "Unit" of electricity?
In your electricity bill, 1 Unit is equal to 1 Kilowatt-hour (kWh). This means if you run a 1000-Watt appliance for exactly 1 hour, it will consume 1 Unit of electricity.
The Cost Formula
To find out how many units an appliance uses daily, we use the following formula:
Units (kWh) = (Appliance Wattage × Daily Hours Used) / 1000
Daily Cost = Units × Electricity Rate
Daily Cost = Units × Electricity Rate
Example Calculation
Assume you run a 1500-Watt Air Conditioner for 8 hours every night, and your local electricity provider charges ₹8 per unit.
- Daily Units = (1500 × 8) / 1000 = 12 Units/day.
- Daily Cost = 12 Units × ₹8 = ₹96/day.
- Monthly Cost = ₹96 × 30 days = ₹2,880/month just for one AC!
