Electric Cost Calculator: How Does it Work?

Posted on by Everything Energy 3 minutes 30 seconds

If you’re curious about your monthly electricity usage and want to do some exploring, you’re in luck. There are a few ways to research this topic. One simple way is to use an online electric cost calculator. 

What is an electric cost calculator?

An electric cost calculator (also sometimes called electricity bill calculator, energy cost calculator, watt cost calculator, etc.) is an online tool. It helps you figure out the cost of using an appliance or electronic device. Just input the requested data, and it generates the cost. This can be a helpful tool to identify inefficient appliances. Or you can use it to see which appliances or electronics use the most energy in your home.

What are the best electric cost calculators?

You have many choices when it comes to using an electric cost calculator. But, each one has most of the same fields and they do the same thing. So, any one you choose should provide you with the information you’re looking for. 

Sample online electricity calculators

Here are a few options you can try:

What information do I need to calculate my energy usage?

Instructions should appear on the screen for the electric cost calculator you want to use.

To calculate electricity cost for specific appliances or devices, you will need the following information:

How is the cost of using an appliance calculated?

The formula to calculate the cost of using a single appliance is:

(Watts/1,000) x Hours Used Per Day x Price per kWh = Cost to Operate Appliance Per Day

To find the cost to operate an appliance per month, simply multiply your total from above by the number of days in the month. To find the annual cost to operate, multiply your total from above by 365.

How do I figure out an appliance’s usage without using an electric cost calculator?

Maybe you want to try a different method of calculating an appliance’s usage cost. Or perhaps you don’t know the wattage of your appliance(s). In that case, you could use a Watt-meter instead. You plug an appliance into this small device, then plug the device into the wall. It then measures the appliance’s wattage and how much it uses while it’s plugged in. 

You can even enter your electricity price per kWh into the device. Then, it will also calculate your cost to operate for as long as it’s plugged in.

How do I calculate my entire energy bill?

If you want to estimate your entire energy bill, you could perform the above exercise for all of the large and small appliances and electronics in your home. However, using an electric cost calculator in this way would be very time consuming. 

Instead, you can see monthly bill estimates when you shop for electricity plans on Everything Energy. Simply enter your ZIP code and your average monthly kWh usage—500, 1000 or 2000. The rest is calculated for you.

What other types of electricity usage calculators exist?
