Watts Required for Starting Versus Running a Refrigerator or Freezer

Refrigerators and freezers are driven by electric motors, which need more power when they are first turned on (thus the term “starting watts” for these appliances). Refrigerator/freezer sizes, energy classes, temperature differences, and other factors have a significant impact on the actual power used.

More powerful older models may use 700-1000 watts when operating and 2000-3000 watts when first powered up. If you have a big home refrigerator or freezer that consumes more than 500 watts, look into its energy star rating.

Purchasing a new, the more energy-efficient appliance may result in significant energy (and money) savings over a period of time if done correctly. We use the phrase “for a certain amount of time” since the length of time depends on local electric energy costs, the power differential between units, and other factors such as weather.

Typical requirements for a modern refrigerator or freezer are as follows:

For example, a big household refrigerator uses 200-400 operating watts and 1000-1200 beginning watts.

  • a typical household refrigerator consumes 100-250 watts when operating and 700-1000 watts while beginning. 
  • small house refrigerator: 75-150 operating watts, 400-600 starting watts, and so forth.

The following are the power requirements for small home and RV refrigerators: 40-50 operating watts and 80-120 starting watts. Note: The quickest and most accurate way of determining the real power needs of your device is to locate and inspect a tiny plate on the rear of the unit that lists the unit’s electrical specifications.

You might be surprised to learn that, despite the fact that refrigerators consume a significant amount of electricity due to the fact that they are constantly in use, they actually consume less electricity than other major electric appliances such as air conditioners, and water heaters, or clothes dryer.

Payless Power provides a response to the query “how many watts does a refrigerator consume,” assisting us in determining how much our refrigerator contributes to our monthly bills, as well as a few methods we may increase our energy savings as soon as today, according to the company.

Average Wattage for Refrigerators: How to Calculate It?

In order to calculate the average wattage for your refrigerator, you must multiply volts x amps in your wattage calculator using the formula below. On the inner wall of the refrigerator, on the manufacturer’s nameplate below the door, behind the front kick plate, or on the back of the refrigerator, you will find these numbers mentioned.

Older refrigerators usually operate at 115 volts and 7 amps, which may be multiplied to provide an energy consumption of 805 watts in total. Typical beginning wattages of 800-1200 watt-hours/day are used by conventional refrigerators, with an average operating wattage of about 150 watt-hours/day.

When it comes to electricity consumption, refrigerators are reactive devices that need more power to start since they include an electric motor but require considerably less power to operate when they are left turned on.

They also feature internal fans that operate on an intermittent basis, as well as a, defrost cycle that consumes electricity. When it comes to the starting and operating wattage of refrigerators, there are a variety of variables to consider, as you can see below.

The Cost of a Refrigerator on a Monthly Basis

Calculate the cost of each kWh of energy used by your refrigerator to see how much it contributes to your monthly electricity bill. Because refrigerators cycle on and off during the day, the U.S. Department of Energy estimates that they will be in use for eight hours each day on average.

Multiply the 805 watts per hour requirement of your refrigerator by 8 hours to obtain a total of 6,440 watts per day. 6.44 kilowatt-hours are obtained by multiplying the above figure by 1,000.

Because the typical American is paid 12 cents per kWh, it is reasonable to estimate that your refrigerator will cost you 77 cents per day or $23.10 per month in energy charges.

What Should I Do If I Don’t Have My EnergyGuide Sticker with Me?

If you’ve misplaced your EnergyGuide sticker but still want to figure out how much energy your refrigerator consumes, you may not be out of luck.

The EnergyGuide requirements for your refrigerator may be found online if you know where your refrigerator’s serial number is located (it’s typically on a sticker someplace on or inside the refrigerator; look inside the refrigerator door or on the back of the unit).

If all else fails, you can always buy a plug-in energy consumption meter to keep track of your use. This device would be installed in the socket that connects your wall outlet to your refrigerator.

How to Lower the Power Consumption of Your Refrigerator?

What is the average operating wattage of a refrigerator? We’ve found the answer to that query. However, if your refrigerator consumes much more energy than the EnergyGuide guideline, there may be a problem with your equipment.

If the energy consumption of your refrigerator seems to be excessive, you may apply a few techniques and ideas to lower it.

Take a look at the following:

  • Clean the inside of your refrigerator.
  • Regardless of the size or brand of your refrigerator, dust and dirt tend to accumulate behind and beneath it. Make a habit of pulling your refrigerator away from the wall and cleaning out as much dirt as you can on a regular basis.
  • Pay close attention to any fans or air vents in your refrigerator, as if these get blocked, your refrigerator will have to work harder to keep up. Seals that are leaking should be checked.
  • If the rubber seals surrounding the doors of your refrigerator or freezer crack or peel away, they may not create a completely airtight seal. This means that your refrigerator will have to work more in order to maintain a regulated temperature.
  • The temperature should be adjusted. In order to keep food fresh, the fridge must maintain a constant temperature of 37°F or below (the refrigerator-freezer should maintain a constant temperature of 0°F). If your temps are lower than this, you are just squandering your money on electricity.

According to Energy Star, certified refrigerators use 20 percent less energy than ordinary models, compared to their counterparts. Not ready to make the financial investment required to upgrade your home?

Here are some free and low-cost suggestions from Payless Power to assist you in getting the most out of your existing appliance’s energy efficiency.

1. Keep it out of direct sunlight.

A cool location away from any heat sources, such as big windows that get a lot of sunlight or the oven, is the ideal place to store your refrigerator. Already working hard to evacuate hot air, refrigerators are put to the test when the air around them is scorching.

2. Move at a rapid pace

For example, avoiding leaving the refrigerator door open may help you break negative habits and save money on your energy bills.

As long as you leave the fridge door open, the compressor is activated, increasing the amount of electricity required to run the appliance. Make every effort to get what you need from the refrigerator as soon as possible and close the door as quickly as feasible.

3. Select the Appropriate Temperature

The use of a refrigerator or freezer set at extremely low temperatures results in significant energy waste. Make certain that the internal thermostats for the refrigerator and freezer are adjusted to the optimum temperatures of 37 degrees Fahrenheit for the fridge and 0 degrees Fahrenheit for the freezer

4. Keep it clean on a regular basis

Do yourself a favor and include regular cleaning of your refrigerator every three months on your to-do list of tasks.

Remove the refrigerator from the wall so that you may clean beneath the fridge as well as the coils on the back, and then remove and clean the kick plate on the front of the refrigerator. When your refrigerator has the capacity to breathe more easily, it will undoubtedly use less energy while running.

5. Only ice-cold food, and enough of it

Take the time to allow your hot leftovers to cool before placing them in the refrigerator to avoid overworking your refrigerator compressor. As a result, only room temperature or cold food should be stored in your refrigerator.

Additionally, make sure that your freezer is at least three-quarters full so that it does not have to work harder to chill down empty space when it is not needed.

6. Are you willing to spend a little money? Gaskets should be replaced.

It is critical that your refrigerator does not leak any chilly air into the room. This may result in a significant waste of energy. You should replace the rubber gaskets surrounding your refrigerator and freezer if you notice that they are no longer effectively retaining cold air in the refrigerator or freezer.


All in all, the monthly cost of operating a refrigerator is quite cheap, but it depends on the size and cost of your refrigerator.

If you’re trying to conserve energy, your best choices are to switch to a newer, more energy-efficient refrigerator or give your existing appliance some well-deserved repair. Either of these solutions should result in significant energy savings on your monthly bill!
