Electricity cost - single usage estimates the cost of electricity needed to run a device for a particular period of time.

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 how much it costs to charge your Tesla, 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.

How to reduce my electricity cost?

You can play with the variables at the Omnicalculator too Electricity cost calculator, or do as follows:

  1. Reduce the usage time of your most powerful equipment. Some examples are hairdryers, HVAC, and microwaves.

  3. Move to a country/state where electricity cost is lower.

How to calculate my electricity bill?

Try using the Omnicalculator tool Electricity Cost-single usage calculator or do as follows:

  1. Get the power of each capacity and record the time they are working.
  2. Multiply each appliance's power by its operating time to get the power consumption. In case you get the result in watts-hour, convert it to kW-hr by dividing the answer by a thousand.
  3. Multiply your power consumption by the electricity cost in USD per kW-hr.

What uses a lot of electricity?

Electrical heaters consume a lot of electricity because the heat they produce is not focused on a specific point; instead, they aim to heat environments where there are a lot of heat losses. Water heaters and HVAC are other sources of high electricity consumption.

Is 100 kWh per day a lot?

Yes, it is. 100 kWh per day equals 3000 kWh per month, exceeding the U.S. average electricity consumption of 893 kWh per month. Try adding the electricity cost in USD per kWh to the Omnicalculator tool Electricity cost to find out how much you will have to pay at the end of the month.
