If you are worried about your electricity bill or are not able to understand how your electricity bill is getting so high then you are in the right place.

In this post we are providing you Household Electricity Consumption Calculator, with the help of this calculator you can calculate the monthly electricity bill of your house.

The main thing is that this tool does not depend on your country, if you are a citizen of any country then this tool will help you for example whether you are a user of USA, India, UK, Malaysia or any other country.You can use this tool.

It is a difficult task to find out how many units of electricity the TV, fridge and AC  in the house consume. It is difficult to find out how much electricity any one appliance consumes and electricity bill also does not provide information about how much electricity was used in the AC ,how many units of electricity wa spent on ironing clothes.To estimate home electricity consumption, you need to understand what appliances you have, how long you use them, and what is their wattage.

This post will help you estimate your household electricity consumption:

Step 1: List Your Devices:

List all the appliances, from large appliances (like fridge, washing machine, and air conditioner) to small appliances (like TV, computer, and light bulbs).

Step 2: Find the wattage of each appliance:

You can find wattge of device on the device label or in the user manual. If you can't find it, you can search online using the model number. Below we have provided the Power Consumption Chat of Household Appliances you can have look on that.

Step 3: Estimate Daily Usage

Estimate how many hours each device is used daily or monthly.For example, a refrigerator may be run continuously, while a TV may only be used for a few hours in the evening.

Step 4: Calculate daily energy consumption:

Multiply the wattage of each appliance by the number of hours it is used each day and  will give you the daily utility power-hours (Wh) that are consumed by each appliance each day.

Step 5: Convert to kilowatt-hours (kWh):

Divide the total watt-hours by 1000 to get kilowatt-hours (kWh), which is the standard unit of energy consumed by utility companies.

Step 6: Add Contribution:

Get your total daily energy consumption by adding up the kWh for all appliances.

Step 7: Monthly usage:

Estimate your monthly energy consumption by multiplying your daily energy consumption by the number of days in the month.


Let's say you have a fridge (200 watts, 24 hours/day usage), a TV (100 watts, 4 hours/day usage), and a light bulb (60 watts, 3 hours/day usage).

Daily consumption(Wh) = (200 watts * 24 hours/day) + (100 watts * 4 hours/day) + (60 watts * 3 hours/day) = 5200 Wh + 400 Wh + 180 Wh = 6000 Wh

Daily consumption(in kWh ) = 6000 Wh / 1000 = 6 kWh

Monthly consumption(in kWh ) = 6 kWh/day * 30 days/month = 180 kWh/month

Often electricity consumers face problems after seeing the electricity bill. They start wondering why they got so much electricity bill this month.

How did the bill get so high despite reducing electricity usage? Such questions arise in the minds of many consumers.

This question may also come to your mind. If you are a domestic consumer then you would definitely like to know how much electricity is spent on average in a month.

You would like to know how much electricity the appliances installed in the house consume. You would also like to know how to know the electricity bill consumption and what is the solution to save it?

To know this, first understand the meaning of unit. 1 unit means 1 kilowatt per hour i.e. if an appliance of 1000 watts is used for 1 hour then it consumes 1 unit of electricity. You may have LED bulb, fan, AC, TV, fridge, tube light, microwave oven, iron, washing machine, laptop and mixer in your house. If 3 bulbs of 9 watts each burn for 

10 hours, it will consume 270 watts of electricity. Similarly, if 4 fans of 60 watts each are installed in the house and run for 12 hours, then 2880 watts of electricity will be consumed.

If a 1600 watt AC used for 5 hours, it will consume 8000 watts of electricity. If there is a TV and it runs for 2 hours, it will require 140 watts of electricity. A 200 watt fridge will consume 1600 watts of electricity when it runs for 8 hours. 

If a 750 watt iron is used for half an hour, it will consume 375 units of electricity. If your 50 watt laptop runs for 2 hours, it will consume 100 watts of electricity. In this way you can know about the power unit hour wise.

Imagine that in a day all the appliances in your house consume 15000 watts of electricity. 

If we divide it by 1000, the result will be 15. That means 15 units of electricity is spent in your house in a day. For the entire month it was 450 units. 

To reduce your energy consumption, you can use low-energy appliances, reduce the use of appliances, and implement energy-saving measures.You can also analyze your electricity bill to see where your energy is being used.
