How to Calculate Electricity Consumption at Home?
Every electrical appliance in the market comes with a rated wattage or a range of operational power 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 on the above table. Thus, with new innovations, the home appliance brands are constantly upgrading their products focussing on power-saving solutions.
To calculate power consumption, you must know that the consumed electricity depends mostly on two factors-
- Wattage of the appliance
- Run time
By mutiplying these two factors, we can get the theoritical 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 changing efficiency. New appliances usually runs with approximately 90% efficiency. With time, natural deterioration starts in various parts of the machine. It results in decreasing efficiency of the appliance. Therefore, to keep the efficiency up, you need proper cleaning and maintenance.
To calculate the electricity cost, multiply the power consumption with the electricity tariff in any currency.
All these factors are considered to design this power consumption calculator. So, simply put the required information and calculate the power consumption in a fraction of a second!
