This energy consumption calculator can help you estimate the electrical power consumption per day, month and year per each typical appliance in your household.

Appliance type:*
Power consumption:*
Hours of use per day:*

## How does this energy consumption calculator work?

In order to estimate how much energy is consumed in your household and check whether you stay within your budget with your monthly expenses the following 3 figures should be provided:

■ What are the appliance types that are used in your household?

■ The power consumption per each appliance type.

■ Hours of use per day which is the estimated time the appliance is used.

To simplify your mission this energy consumption calculator has incorporated a predefined list with appliances and each one has by default an average power consumption value in watts that can be edited whenever needed, as detailed below:

 Appliance type Power consumption in watts 100 watt incandescent bulb 100 Air Conditioner for Room 1100 Blender 300 Central Air Conditioner 5000 Clothes Dryer 3200 Clothes iron 2300 Coffee Machine 1500 Desktop computer 100 Dishwasher 1600 Electric kettle 2000 Fan 70 Hair Dryer 1500 Heater 2000 Laptop 60 LCD TV 200 Microwave 900 Oven 3000 Plasma TV 300 Refrigerator 250 Shaver 15 Standard TV 150 Stereo receiver 190 Toaster oven 1000 Vacuum cleaner 1200 Video Game Player 195 Washing machine 2000 Water heater 3800 Other Any custom value

For more flexibility, by choosing the “Other” option from the appliance list you can input any custom power consumption, while there are two measurements units available: watts (w) and kilowatts KW.

The formulas described below are used:

■ In case the power consumption is expressed in watts (W) the energy consumed per day is:

EC(kWh/day) = P(W) * T(h/day) / 1000(W/kW)

■ When the power consumption is measured in kilowatts (KW) the energy consumed per day is:

EC(kWh/day) = P(W) * T(h/day)

The results displayed consist not only in the daily energy consumption figure, but also the total energy consumption per month, respectively year which are obtained this way:

ECper month = ECday * 30

ECper year = ECday * 365

Where:

P = power consumption

T = Hours of use per day
