How Electricity Bill Is Calculated
Electricity bills are calculated based on the total units of electricity consumed in your home. One unit of electricity equals 1 kilowatt-hour (kWh). To calculate electricity consumption, multiply the appliance wattage by daily usage hours and the number of days used.
For example, if a 1500W air conditioner runs for 8 hours per day, the monthly electricity consumption will be approximately 360 units.
Electricity Consumption Formula
The basic formula to calculate electricity usage is:
Units (kWh) = (Watts × Hours × Days) ÷ 1000
Once you know the total units consumed, multiply it by your electricity rate to estimate your monthly bill.
Example Electricity Bill Calculation
- Appliance: Air Conditioner
- Power: 1500 Watts
- Usage: 8 Hours per day
- Electricity Rate: ₹8 per unit
Monthly Units = 360 kWh Estimated Bill = ₹2880
