# Electricity Cost Calculator (Single Usage)

This calculator tells you how much it costs to run an electrical device for a certain amount of time. It's often the topic of conversation and most of the time we have no clue how much it really costs to run our electric appliances. For example, you might be wondering how much it costs to boil a water in an electric kettle. Say we want to boil 2 liters (a little more than 7 cups) in a 2000 Watt kettle, and you know it takes it 6 minutes to do it. This calculator will then do the calculation for you, and return a value of 0.2 kWh. With an average price of $0.13 per kWh, we arrive at the value of 2.6 cents per single use.

If you're interested in a recurring usage of utilities such as charging your car, try the electricity cost calculator. Let's give a hypothetical example: you use your 700 Watt vacuum cleaner twice per week for half an hour each time, so an hour per week. It's 700 Wh (0.7 kWh) per week, or 36.525 kWh per year. With the same $0.13 per kWh price of electricity, your hoover costs you $4.75 per year.
