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

## 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:

**EC _{per month }= EC_{day} * 30**

**EC _{per year }= EC_{day} * 365**

Where:

P = power consumption

T = Hours of use per day
