How To Determine What you Pay for Electricity Using your Power Bill
Method #2 - Using Averages

This guide is intended to help you get an average value of how much electricity costs you per unit. If you are looking for a more accurate method, we have 3 different guides to choose from listed here. However, for our example power bill below both of the power bill based methods yield a very similar result.

If you are unsure what a kilowatt hour is, then you may want to read What is A Kilowatt Hour first.

By looking at your monthly power bill we can determine an average of how much you pay for electricity across all items in your home. Using this method we will assume that the power company charges you the same amount for the first unit of electricity that you use as the last unit of electricity that you use. This is not necessarily true, but it will yield a very accurate guess.

Lets take a look at a sample power bill.

There are 2 values circled: Amount Used This Month, and Total New Charges. The value that we want is Cost / kilowatt hour, so the math is simple:

Cost
193.38
--------------
=
Cost / kilowatt hour
  therefore  
------------
=
0.0873 / kWh
Kilowatt hours
2,215

 

In this example, the cost per kilowatt hour is 0.0873. If you are doing this in US Dollars, that's 8 cents.

We also have a guide to help you learn to Read You Power Meter to Determine Power Usage.
