If you don’t want to pay someone to get an exact amount of what your utility bill will be for the month, you can calculate your electricity bill cost by using a simple mathematical formula. For your calculations, you will need three pieces of information for each appliance: the wattage, the average number of hours you use it per day, and the amount you pay per kilowatt-hour (kWh) of electricity. If you don’t know where to find these things, don’t stress, because they are an easy find. The first bit of information, the kWh, can be located on your home’s electricity bill. Next, the average number of hours you use the appliance per day requires a little bit of thinking on your part. Lastly, to find the wattage, look at the bottom or back of the appliance, as it is usually printed on it. You’ll be looking for some numbers followed by a “W”, which indicates the appliance’s wattage.


Once you have found these three pieces of information, you’re ready to use your electricity bill calculator—your brain! Here is the simple formula that you will use:


  1. Appliance wattage X average number of hours used per day
  2. Divide answer by 1000
  3. Multiply that number by your kWh rate


Congratulations! If all of your calculations are correct, then you should have the amount you will pay for that appliance. We know it can be a bit tedious to do this process over and over for each appliance in your household. If you don’t have the time or would rather have a computer do all the work for you, you can check out the many free electricity bill estimators online.
