How To Use This Power Consumption Calculator?

  1. Check any home appliance’s rated power (watts) on its label and put it in the first box on the calculator. For example, a ceiling fan has a rated power in the range of 35-80 watts. You can also sum up the total wattage of various home appliances and put it in the box to calculate the home power consumption in India.
  2. After completing the previous step, put the duration of use in the next box.
  3. Choose an efficiency for your appliance. For a typical new home appliance, it is usually around 90%, but with time, the equipment becomes less efficient.
  4. Now, click on the “Calculate Power Consumption” button. The calculator will show you power consumption and electricity bill on a daily, monthly, and yearly basis.

What Benefits Can You Get From This Energy Calculator?

  • Understanding which home appliance consumes how much electricity from this power consumption calculator allows you to plan your power requirement and usage more efficiently.
  • You can also get an overall idea of how much electricity your home appliances like fans, lights, air conditioners, refrigerators, TV, and washing machine consume.
  • Get daily, monthly, and yearly estimations of power consumption with a click.

How to Calculate Electricity Consumption at Home?

Every electrical appliance in the market comes with a rated wattage or operational power range in watts. Some appliances allow the user to change the power depending on the requirement.

The actual wattage of common household appliances should be within the range of power mentioned in the above table. Thus, with new innovations, home appliance brands constantly upgrade their products, focussing on power-saving solutions.

To calculate power consumption in India, you must know that the consumed electricity depends mostly on two factors-

  1. The wattage of the appliance
  2. Run time

By multiplying these two factors, we can get the theoretical power consumption by the appliance.

Power Consumption= Wattage*Run Time

But the actual consumed power can vary from the rated wattage because of the machine’s efficiency. New appliances usually run with approximately 90% efficiency. With time, natural deterioration starts in various parts of the machine. It results in decreasing the efficiency of the appliance. Therefore, you need proper cleaning and maintenance to keep the efficiency up. To calculate the electricity cost, multiply the power consumption with the electricity tariff.

All these factors are considered to design this electricity consumption calculator. So, simply put the required information and calculate the power consumption in a fraction of a second!
