How much power does a freezer use
Depending on the model, a freezer does use between 300 and 700 Watts of power.
If you know the manufacturer and the model of a freezer, it is quite easy to search for the specifications sheet on the internet.
On the freezer specifications sheet you can search the freezer power consumption and with some easy calculations find out it’s electricity usage and electricity cost.
The specifications sheet we show on the picture above show that this freezer consumes 0,46 Kilowatt hours (kWh) per day.
Assuming that the freezer is powered on the whole year, we can calculate that in one year it will consume 168 Kilowatt hours (kWh).
0,46 kWh x 365 days = 167,9 kWh per year
How to calculate power from voltage and current
If you only know the voltage and current of your freezer, you can calculate the power consumption, in Watts, using the calculator below.
For more information about Power, Voltage and Current, scroll down to the ‘Electricity Measurement Units’ section.
Electricity cost calculator
Once you know the power consumption, you can use the following calculator to estimate the electricity cost.
For example:
> If your freezer has a power rating of 0,56 Kilowatts per hour (kWh)
> If it is switched on 320 days per year
> If you are paying 0,2 euro (or dollars or pounds) per every kWh you consume
You will be paying around 36 euro (or dollars, or pounds, or…) per year in electricity costs.
How much does electricity cost
If you don’t know how much you are paying per kWh, you should be able to find the cost per kWh on your electricity contract or in one of the electricity bills.
Alternatively, if don’t have access to your contract or your electricity bills, this website does show the electric prices per country.

How to measure the exact power consumption and electricity cost
If you want to know the exact electricity usage of an air conditioner, your best option is to use a plug in power meter to measure the exact power consumption and electricity cost.
Clicking on the image below it will redirect you to the Amazon page where you can have a look to the specifications of the power meter we use for our measurements.
All of our house appliances and devices like the washing machine, the dishwasher, the TV or the printer are plugged to a wall socket.
So, with a power consumption meter we can determine how much electricity our appliances or devices are using and, more importantly, we can measure the electricity usage over a period of time.
If you want to find out how you can use a plug in power meter to measure your electricity usage and electricity cost, have a look to this YouTube video.
How to lower the electricity bill
If you think that your freezer it is using too much electricity, here there are five simple ways to reduce the power consumption of a freezer:
1.- Keep the freezer full, but not too full
The freezer temperature can stay cooler for longer periods if the freezer it is full. Still, be careful, because a too crowded freezer will cut down the air flow and increase the risk of warm areas within your fridge.
2.- Do not put hot food in the freezer
Hot food will force your freezer to use more electricity and, also, the temporary temperature increase can be detrimental for the other food in your freezer.
3.- Check the door seals
A damaged gasket will let the cool air escape forcing your freezer to use more electricity to keep the internal temperature.
4.- Make sure that around your freezer there is enough space for a correct air flow
Around your freezer, specially behind where the condenser coils are, there should be enough space for air circulation. If your freezer it is placed too close to the wall, the condenser will not be able to operate efficiently and that will increase the electricity usage. Keep a distance of 30 cm between the freezer and the wall
5.- Keep your freezer in a cool area
If your freezer is placed near the cook, the oven or it is exposed to direct sunlight, the heat will force your freezer to use more electricity to keep the internal temperature.
Frequently asked questions
How much electricity does a deep freezer use
It depends on the model.
For example, by searching on the internet for the freezer model ‘Beko HSA29540N’ we find on the Beko website that this model uses 227 kWh per year.
If you are paying 33 cents per kWh, that means that this specific model will cost you 227 kWh x 0.33 cents per kWh = 74.91 euro/dollar/pounds in electricity per year.
By searching on the internet for the freezer model ‘Liebherr CFf 1870’ we find on the Liebherr website that this model uses 249 kWh per year.
If you are paying 33 cents per kWh, that means that this specific model will cost you 249 kWh x 0.33 cents per kWh = 82.17 euro/dollar/pounds in electricity per year.
How much electricity does a chest freezer use
Chest freezer or deep freezer are the same type of freezer.
We have already provided an answer to the questions above.
The electricity usage of most of the freezers can be found on the internet. Just make sure that you look for it on the manufacturer’s website.
How much electricity does an old freezer use
It depends on how old the freezer is.
If the freezer is maybe 8 or 10 years old, yes, it will use more electricity than a brand new model but the difference may not that great.
If you are concerned that your freezer may be using too much electricity, there are two options:
1. Look on the internet for the freezer specifications and find out how much electricity does it use in Watts or Kilowatt hours.
2. Use a plug on power meter to find the exact electricity usage and electricity cost
How many watts does a freezer use
It depends on the model.
We have searched on the internet for one popular freezer model, the ‘ Beko HSA 47530N’ and on the manufacturer’s website we have found that this freezer model uses 349 kWh per year or 0.861 kWh per day.
For small appliances, it is worth to measure the electricity usage in Watts.
For big appliances like fridges, washing machines or freezers, the electricity usage is measured in Kilowatt hours (kWh).
1 Kilowatt hour is the equivalent to 1000 Watts.
How many watts does a freezer use per day
The same as answered on the questions above, it depends on the model and daily electricity usage can be found on the internet.
Just make sure that you look for it on the manufacturer’s website.
How many watts does a small freezer use
Once again, the answer is ‘depending on the model’.
For small appliances, it is worth to measure the electricity usage in Watts.
For big appliances like fridges, washing machines or freezers, the electricity usage is measured in Kilowatt hours (kWh).
1 Kilowatt hour is the equivalent to 1000 Watts.
We have searched on the internet and chosen three random SMALL freezers:
1. Liebherr GGU 1450 with a daily electricity usage of 0,724 kWh
2. Bosch GTV15NWEA with a yearly electricity usage on 163.84 kWh
3. Beko FSE1073N with a yearly electricity usage of 209 kWh
As you can note, two of the freezers were displaying the electricity usage in kWh per year and one of the freezers was displaying the electricity usage in kWh per day.
If we make a simple calculation we find out that the Liebherr electricity usage per year in 0,724 kWh per day x 365 days = 264.26 kWh per year. So this fridge is the one using the most of electricity per year.

Energy conservation
Energy conservation can be defined as the decision and the act of using less energy
Energy conservation both benefit you and the environment
The act of saving and conserving electricity does benefit you because you will be paying less on your energy bills.
And it also does benefit the environment because conserving electricity prevents any unnecessary waste of natural resources.
Now, at individual level it may not look worth to try to save a few watts here or there.
Still, every little counts and if hundreds or thousands of us do save a little every time, it will make an important contribution towards conserving our natural resources.
Energy conservation calculator
For example, if 9000 households would manage to save as little as 10 Watts per day (0,01 kWh) that would add to 32850 Kilowatt hour (kWh) saved per year.
9000 households x 0,01 kWh per day x 365 days per year
=
32,850 kWh saved per year
That is a considerable amount of electricity, but let’s add additional perspectives for clarity:
> Assuming an average cost of 0,18 euro (or dollars, or pounds, or any other currency) per kWh, we would collectively be saving nearly 6000 euro per year.
> To produce 32,850 kWh of electricity it is necessary to use around 17 metric tons of coal or 56 barrels of residual fuel oil.
Have a look to this page for more information about the amount of resources needed to produce electricity.
In any case it is clear that small energy savings do really count when looking into the bigger picture.
