How much power does a refrigerator use?

It goes without saying that the refrigerator is probably the most essential appliance in your kitchen if not home. Of course, as this appliance is always “on”, it’s a good idea to work out how much power your refrigerator uses. So, if you are wanting to minimize your electricity bill or simply know more about your refrigerators power usage. We’ll help you work it out. 

Fridge power consumption

According to online sources your refrigerator uses between 300 and 800 watts of electricity. The good news is that generally a refrigerator is only running one-third of the time. It actually cycles on and off throughout the day so you can divide your refrigerator’s wattage by three to get the running wattage.

Let’s take a look at how you can work out your refrigerators power usage by using the volts and amps your refrigerator uses when it’s running. The sticker with the information on should be located inside your refrigerator. 

  • The first step is to multiply volts x amps, which will tell you how much wattage your fridge is using.
  • Then divide the wattage by 1/3.
  • So, if your refrigerator has a rating of 120 volts and 4.5 amps the calculation would be as follows:
    120 volts x 4.5 amps = 540 watts
    540 watts divided by 3 = 180 watts
  • To calculate how many watts a refrigerator uses per day:
    180 watts x 24 = 4.320 watt-hours
  • For the yearly power consumption just multiply 4.32 kilowatt-hours x 365 = 1,537,92 kilowatts-hours
  • If you want to know how much electricity your refrigerator uses per month you can calculate the average monthly use by dividing the yearly usage number by 12.

Tips to lower your refrigerator’s power usage

There are a couple things you can do to ensure that your refrigerator is not wasting unnecessary power, which can help keep your energy bills in check. 

  1. If your fridge is old, it might be time for an upgrade. An old model will most likely waste a lot of power to keep your groceries cool.
  2. Check the seals on your fridge. If the seals are porous or broken it could affect the fridge’s power consumption greatly as broken seals will let the air escape.
  3. Keep your fridge full, if possible, this way there is less air that needs to be kept cool.
  4. Clean your condenser coils at regular intervals as they are responsible for keeping the inside cold.
  5. Dial the temperature in your fridge up a notch. If your inside fridge temperature is on the cooler side, you could increase the appliances inside temperature slightly. This will positively influence the refrigerator’s power usage.
