How Can You Calculate Power Consumption of Any Appliance?

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.

These are a typical wattage range of common home appliances and kitchen kitchen appliances-

ApplianceMin. PowerMax. Power
Air Conditioner600 Watts3000 Watts
Air Cooler50 Watts200 Watts
Ceiling Fan35 Watts80 Watts
Dishwasher1000 Watts2000 Watts
Electric Kettle1000 Watts2000 Watts
Geyser/ Water Heater1000 Watts2000 Watts
Induction Cooktop800 Watts3000 Watts
Microwave Oven1000 Watts2500 Watts
Mixer Grinder400 Watts1200 Watts
Refrigerator200 Watts800 Watts
Room Heater1500 Watts3000 Watts
Steam Iron1000 Watts2200 Watts
Television70 Watts300 Watts
Toaster600 Watts1200 Watts
Tube Light20 Watts40 Watts
Vacuum Cleaner1000 Watts2000 Watts
Washing Machine700 Watts2000 Watts

The actual wattage of common household appliances should be within the range of power mentioned on the above table. 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-

  1. Wattage of the appliance
  2. 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 apppliances 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. To keep the efficiency up, you need proper cleaning and maintenance.

Use these following amazing calculators to estimate Capacity, Power Consumption of various Home and Kitchen Appliances like Air Conditioner, Induction Cooktop, Air Cooler, Kitchen Chimney and many more!
