If you are wondering how much power single-door refrigerators consume, or do old single-door refrigerators consume a lot of power then you have come to the right place.
In this article, we will see single-door refrigerators’ power consumption and also look at the cost to run them.
Single-door refrigerators comes in different capacities ranging from 190 ltr to 270 ltr. Depending on the size and the number of energy-saving stars the annual power consumption of single-door refrigerators varies from 100 kWh to 200 kwh.
To get a well-rounded answer on the power consumption of single-door refrigerators, I have browsed through amazon and a bunch of other e-commerce websites to find out the annual power consumption of almost every size single-door refrigerator and compiled the following data.
Single-Door Refrigerator Power Consumption:
In almost every country, all refrigerators available today are energy star rated, hence, you can go to the refrigerator manufacturer’s website or your country’s top e-commerce website and find an energy-saving label associated with a refrigerator.
The below image shows the annual power consumption of a Samsung 192 ltr, 4-star single-door refrigerator listed on Amazon India.
For easy comparison, I have made the following table that shows the power consumption of every size single-door refrigerator from Samsung and LG.
|Annual Power Consumption (kWh)||LG Single-Door|
|Annual Power Consumption (kWh)|
|192 ltr (1 star)||254 kWh||190 ltr (3 star)||164 kWh|
|192 ltr (2 star)||203 kWh||190 ltr (4 star)||131 kWh|
|192 ltr (3 star)||162 kWh||215 ltr (4 star)||139 kWh|
|192 ltr (4 star)||130 kWh||215 ltr (5 star)||107 kWh|
|198 ltr (4 star)||131 kWh||235 ltr (3 star)||169 kWh|
|198 ltr (5 star)||104 kWh||235 ltr (4 star)||143 kWh|
|225 ltr (3 star)||167 kWh||270 ltr (3 star)||174 kWh|
|225 ltr (5 star)||107 kWh|
Few things to notice from the above table,
- The least energy-efficient single-door refrigerator is the 192 ltr (1-star) from Samsung which has an annual power consumption of 254 kWh.
- The most energy-efficient single-door refrigerator is the 225 ltr (5-star) from Samsung which has an annual power consumption of just 107 kWh.
- A similar size and energy star-rated single-door refrigerator from Samsung & LG consumes the same electricity, 192 ltr (4-star) from Samsung consumes 130 kWh, whereas, the 190 ltr (4-star) from LG consumes 131 kWh.
Before we go ahead and calculate the cost of running single-door refrigerators, let us quickly see how stars impact the power consumption of a refrigerator.
How stars affect the power consumption of single-door refrigerators:
If you have done a bit of googling on energy-saving stars or walked inside a store to purchase refrigerators or ACs, you would have surely heard one thing” More stars means more saving”.
That’s absolutely true, but exactly how much saving? let’s find out.
From the above table, we can clearly see,
With an increase in energy-saving stars, the annual power consumption of a refrigerator drops by 20%.
- For example, the 192 ltr (3-star) single-door refrigerator from Samsung consumes 162 kWh, whereas, the 192 ltr (4-star) refrigerator from Samsung consumes 131 kWh (20% less than the 3-star one).
- And the 215 ltr (4-star) single-door refrigerator from LG consumes 139 kWh, whereas, the 215 ltr (5-star) refrigerator from Samsung consumes 107 kWh (20% less than the 3-star one).
- Hence, by the time you go from a 1-star refrigerator to a 5-star refrigerator, the annual power consumption becomes almost half. The 192 ltr (1-star) single-door refrigerator from Samsung consumes 254 kWh, whereas, the 198 ltr (5-star) refrigerator from Samsung consumes 104 kWh (less than half of what 1-star consumes).
The bottom line is “More energy stars mean more saving”, to quantify it, with every additional energy-saving star you can expect almost a 20% reduction in power consumption.
Now let’s look at how much it costs to run single-door refrigerators.
How Much Does It Cost To Run Single-Door Refrigerator:
You can find the cost to run any refrigerator by using the below formula.
Cost to run a refrigerator = Power consumption of the refrigerator X electricity tariff.
You can find the annual power consumption of a refrigerator from its energy-saving label.
The electricity tariff is basically the amount your electricity provider charges you for one kWh (unit) of electricity. I live in Mumbai, India here the electricity tariff is Rs 12/kWh.
Unit or kWh is the electricity consumption of an appliance, this is printed on your refrigerator’s energy-saving label.
I have put together the following table that shows the electricity tariff of a few countries.
Electricity Tariff Around The World:
|Country||Electricity Tariff||Country||Electricity Tariff|
|United States||$ 0.154/kWh||India||Rs 6/kWh|
|United Kingdom||£ 0.27/kWh||Germany||€ 0.44/kWh|
|Canada||C$ 0.30/kWh||Philippines||₱ 9.70/kWh|
|Australia||A$ 0.32/kWh||South Africa||R 2.558/kWh|
You can also check out the following resources to know your electricity tariff:
In the below table, I have calculated the annual running cost of Samsung single-door refrigerators in Mumbai (India), the Philippines, and the US.
(As we saw above almost every brand of refrigerator consumes the same power for a specfic capacity. Hence, this table applies to pretty much all manufacturers)
|Annual Power Consumption (kWh)||Mumbai, India|
|192 ltr (1 star)||254 kWh||Rs 2,540||₱ 2,463||$ 40.64|
|192 ltr (2 star)||203 kWh||Rs 2,030||₱ 1,969||$ 32.48|
|192 ltr (3 star)||162 kWh||Rs 1,620||₱ 1,571||$ 25.92|
|192 ltr (4 star)||130 kWh||Rs 1,300||₱ 1,261||$ 20.80|
|198 ltr (4 star)||131 kWh||Rs 1,310||₱ 1,270||$ 20.96|
|198 ltr (5 star)||104 kWh||Rs 1,040||₱ 1,008||$ 16.64|
|225 ltr (3 star)||167 kWh||Rs 1,670||₱ 1,619||$ 26.72|
|225 ltr (5 star)||107 kWh||Rs 1,070||₱ 1,037||$ 17.12|
From the above table, its pretty clear that it does not cost much to run single-door refrigerators, especially the ones with higher energy-saving stars.
However, if you have an old refrigerator that is not energy-star rated, then I think its time to buy one. As old refrigerators consume a lot of electricity.
Lets see exactly how much.
Do Old Refrigerators Consume a Lot Of Power?
If you are browsing the web to find out tips to reduce your house electricity bill, then this would surely come up ” Replace old appliances with new energy-efficient ones.”
How true is this? let’s find out.
The image on the left is of my refrigerator. It’s a 2010 model, 230 ltr, 4-star rated energy-efficient refrigerator from LG.
Its annual power consumption is 460 kWh.
The image on the right is of a 2021 model, 260 ltr, 3-star refrigerator from LG, its annual power consumption is just 198 kWh.
Hence, you can clearly see, in the last 10 years, the power consumption of a same-size refrigerator, from the same manufacturer, with a similar energy star rating has drastically reduced by more than half.
(Well my old fridge had 4 stars and the new one has just 3, but still, its power consumption is half of my old fridge).
Now imagine, you have a refrigerator from 2005, just replacing that with a new energy-efficient fridge will drastically reduce your electricity bill.
Hence, it’s safe to say, yes, old refrigerators consume a lot of electricity. In fact, old refrigerators consume almost two times more power than new refrigerators of similar size.
If you have reached this far, then it would be pretty clear to you that new modern refrigerators don’t consume a lot of electricity.
Here are a few tips to reduce your refrigerator power consumption even more.
Energy Saving Tips To Keep Your Refrigerator Operational Costs Low
- Keep the refrigerator full – This sounds bizarre but keeping your refrigerator full helps to cut down the power consumption. A full refrigerator does not mean overstuffing the refrigerator, it means a more organized fridge that has enough place for proper air circulation.
- Optimize temperature settings – Most of the refrigerators are running at temperatures way below its needed. On average a temperature of 2 C to 5 C is ideal for the fridge compartment and for the freezer, anything between -10 C to -15 C is good. Don’t overdo the temperature. Just switch your refrigerator setting to normal on normal days and below normal on cold days (use the regulator inside your refrigerator).
- Keep the refrigerator door closed – Frequent opening and closing of the refrigerator door puts an unnecessary load on the compressor to cool the fresh warm air that enters the space every time you open the door. If you cut down your door opening frequency you will see a drop in your power consumption.
- Place refrigerator strategically – Two questions your should ask yourself before finalizing your refrigerator place. First, is the place getting direct sunlight? if yes, then look for some other place or restrict the sunlight coming to that place by some means. Second, is there any space between the refrigerator walls and your house wall after placing the refrigerator? Ideally you should keep 6 inches of space on all three sides for proper ventilation.

- Lifestyle changes – Do not keep hot food directly in the refrigerator. First, let the food cool down and then put it in the refrigerator. Periodically clean the evaporator and condenser coils. Keep your food organized so that there is enough space for free movement of air.
