Electricity Bill Calculator — Estimate Your Monthly Power Bill
Surprised by a high electricity bill at the end of the month? An Electricity Bill Calculator helps you estimate your monthly power consumption in advance — so you can identify which appliances are costing the most and take action before the bill arrives.
Understanding the Unit of Electricity
1 Unit = 1 kWh (kilowatt-hour) This means a 1,000-watt appliance running for 1 hour consumes 1 unit of electricity.
Formula:
Units consumed = (Wattage × Hours used per day × Number of days) ÷ 1,000 Monthly Bill = Units consumed × Rate per unit
Common Appliances and Their Power Consumption
1.5-ton AC: 1,500 watts — 8 hours/day = 12 units/day
Refrigerator (350L): 150 watts — 24 hours/day = 3.6 units/day
Washing machine: 500 watts — 1 hour/day = 0.5 units/day
LED TV (43 inch): 80 watts — 6 hours/day = 0.48 units/day
Ceiling fan: 75 watts — 12 hours/day = 0.9 units/day
LED bulb (9W): 9 watts — 8 hours/day = 0.072 units/day
Sample Monthly Bill — 2 BHK Apartment
2 ACs (8 hours each): 720 units
Refrigerator: 108 units
TV, lights, fans: 60 units
Total: approximately 888 units
Bill at ₹8 per unit: ₹7,104
