Here is a detailed post about Refrigerator Power Use. Suppose you are looking for refrigerator power consumption calculator. Then reading this article may help. It also includes inverter refrigerator power consumption.
This is a guide to Refrigerator Power Use. It’s tempting to think there’s not much you can do about the electricity costs of your refrigerator. You can’t live without one, and you can’t turn it off. But if your refrigerator has been with you for a long time, it may be that a new one will pay for itself in just a few years through a reduction in your electricity bill. And even if you already have a newer model, there are still a few tweaks that can help you make it as efficient as possible. Read on for tips on figuring out how much electricity a fridge uses and how to determine when it’s time to start looking for a replacement.
Refrigerator Power Use

In the 20th century, it was fairly easy to make a ballpark estimate of refrigerator energy consumption because refrigerators weren’t changing much from year to year. But refrigerator energy efficiency has progressed rapidly in the last two decades, and most of today’s models use 25 percent or less of the energy consumed by the refrigerators of the 1970s.
Since refrigerators can sometimes keep running for decades themselves, there are all sorts of fridges in today’s kitchens — from ancient energy hogs to modern marvels of efficiency. So, if you’re curious about how much you’re spending in refrigerator electricity usage, one of the biggest clues is its manufacturing date. You can use ENERGY STAR’s Flip Your Fridge calculator to quickly estimate how much you might be able to save by replacing your refrigerator with a modern ENERGY STAR refrigerator. All you need to know is your refrigerator’s approximate model year and size, plus your electricity retailer’s kWh rate (look on your monthly bill).
How Much Electricity Does My Fridge Use?
By way of example, if you have a fridge with a top freezer from the 1980s with a capacity of 19.0-21.4 cubic feet, it’s likely to use around 2,000 kWH per year. If you pay $.10 for electricity per kWh, that means the aging refrigerator is costing you about $.55 per day, $16.67 per month, and $200 per year.
A modern-era Energy Star-rated fridge, by comparison, might only use 350 kWh annually. At the same $.10 per kWh price, that’s around $.10 a day, $2.9 per month and $35 per year, meaning that you’re looking at annual savings of $165 by jettisoning the old refrigerator in favor of a new one.
How to Estimate Your Refrigerator’s Annual Electricity Cost
If you ever find yourself wondering “exactly how much electricity does my fridge use?”, you can figure it out as well as your monthly costs if you determine your refrigerator power consumption in watts. Since 1980, appliance manufacturers have been required to participate in the Energy Guide program. Those black and yellow labels you see on every appliance sold at retail stores are designed to make it easy for shoppers to estimate electrical consumption costs before they decide what to buy.
If you saved all the original documentation that came with your refrigerator, you may still have the Energy Guide label. If not, find your refrigerator’s model number by looking for a label on the back or behind the kickplate on the lower front. Once you have the model number, you may be able to look up the Energy Guide information on the manufacturer’s website or obtain it by contacting their customer service department.
The most important thing the Energy Guide label will tell you is the estimated annual electricity use in kilowatt hours, or kWh. The label will also give you an estimated yearly operating cost, but this figure is based on the national average electricity rate. You’ll get a better estimate by checking your exact electricity rate on your bill and multiplying it by the kWh total you find on the Energy Guide label. To see your estimated monthly cost, just divide by 12. Refrigerator power consumption should show very little variance month-by-month, since they run 24 hours per day.
Energy Saving Tips for Your Refrigerator
You might be able to make a huge leap in energy efficiency by upgrading to a modern ENERGY STAR refrigerator, but there are lots of free and cheap hacks you can use to get a little more out of the fridge you already own:
Keep it clean.About every three months, pull the refrigerator away from the wall and dust the coils on the back of the fridge. Remove and wash the kickplate from the front of the fridge, if applicable, and use a long, thin duster or brush to clean underneath. When your fridge breathes easier, it uses less energy.
Check your temperature.37 degrees Fahrenheit is ideal for the fridge, and 0 degrees is optimal for the freezer. If you’re using colder settings, you’re wasting energy.
Seal it up.The rubber gaskets around your fridge and freezer doors are what keep cold air in. If you feel cold air leaking out, it may be worthwhile to replace the gaskets.
Keep only cool food inside.If you have hot leftovers, let them cool on the counter before you put them in the fridge. You’ll save your refrigerator’s compressor from going into overdrive.
Place it in a cool spot.Refrigerators expel hot air, and must work harder to do so if the surrounding air is also hot. The best place to put a refrigerator is in the kitchen’s coolest corner, away from the oven or big, sunny windows.
Whether you’re ready to upgrade or just want to tweak your energy consumption, you’re doing the right thing for your wallet and the planet. Make like your fridge and stay cool.
What Affects Fridge Power Use
The actual energy consumption of your fridge or freezer will depend on many factors. These include:
- Type. For example, a commercial display fridge can use ten times more than your bar fridge at home.
- Size. Anything with a larger volume, such as side by side fridges, use more electricity.
- Location. If the fridge is in a warm position, or poorly ventilated, it will use more power.
- Season. All refrigerators use more power in summer than in winter as the ambient temperature is higher.
- Usage. If the fridge door is opened frequently or held open, the compressor will need to work harder to keep things cool. Also, an empty fridge may need to work harder than a reasonably-stocked fridge because more ‘cool air’ is replaced with ‘warm air’ each time the door is opened.
- Temperature set point. The factory setting may keep the fridge cooler than is needed in your home.
- Age. Old refrigerators are usually less energy efficient than new high star rated fridges.
- Condition. If the seals are in poor condition, your fridge will be less efficient.
Home Refrigerator Power Consumption
For a quick check of fridge wattage, find the compliance plate and make some quick calculations. The compliance plate is usually located inside the fridge.
The fridge compliance plate is a useful first approximation of power usage. In this case, it indicates the fridge uses 130 Watts when on.
For example, for my refrigerator, the numbers are:
- Refrigerator wattage = 130 Watts
- Estimated usage = 8 hours per day (33% duty cycle)
- Total energy = 130W x 8h = 1040Wh = 1.04kWh/day
- Total cost = 1.04kWh/day x 365 days x $0.25/kWh = $94.90/year
Basic Refrigerator Power Consumption Calculator
To summarise the above calculation, we have:
- Fridge Wattage x Hours Per Day = Watt-hours per day
- Watt-hours / 1000 = kWh per day
The above fridge power consumption calculator is not very accurate because the fridge may not consume its rated wattage. Also, the compliance plate does not account for all the other variables that affect power usage. For example, your fridge may have a fault or other issue causing it to operate for 16 hours per day, not 8. That alone would double its usage!
Better Fridge Power Consumption Calculator
To find out the actual wattage of your refrigerator, you need to use a power meter. Our Plug-in Power Meter is the most popular and cheapest option. The Power Mate Lite is our highest accuracy option, often used by professional energy auditors.
Use a plug-in power meter to check your fridge’s power consumption.
These devices have the benefit of measuring rather than estimating. You can plug your fridge in for a full 24 hour period and see how many kWh it uses. More importantly, you can make some changes and see if you can reduce your energy consumption.

What About The Fridge Star Rating?
Energy efficiency ‘star ratings’ are a great buying guide. But because of the variable factors described above, the only way to know how much power your fridge is really consuming is to use a plug-in power meter.
Fridge Wattage of Other Fridges
Using a Power Meter, I found that the small fridge in our office used between 90 and 100 Watts when the compressor was running. That resulted in 0.6 kWh used over 24 hours, or around 221 kWh per year. The Power Meter showed that the fridge was drawing power for only 6 hours and 10 minutes in 24 hours.
Commercial refrigeration is more complex to measure, but the opportunities for energy savings are much greater. Some of the businesses for which I have completed business energy audits initially spent well over half of their electricity costs on refrigeration. This is one reason why refrigeration makes number six in our top 10 causes of high power bills.
Check out this commercial refrigerator which is almost empty and still burning through over $1,000 per year in electricity costs!
Four Ways to Cut Fridge Power Consumption
1. Ensure fridges are well ventilated. Often fridges are jammed in between wall cabinets which makes their power consumption increase substantially.
2. Consolidate the number of fridges in use. If you have a spare fridge in the garage and only partially fill it, empty it and switch it off.
3. Use timer switches on drinks fridges and bar fridges. This way, any fridge that does not contain perishable food is only on when it’s needed.
4. Check and adjust the temperature settings. Freezers, in particular, are often set far too cold. Use a thermometer to check and change your settings. For domestic refrigeration, 4˚C for the fridge, and -15˚C for the freezer is sufficient and safe.
Is Refrigeration Power Usage Even an Issue?
Don’t forget that refrigeration is only responsible for around 10% of energy usage in most homes. Although it can be much higher in businesses like cafes, clubs, and restaurants. So, if you want to cut your energy usage refrigeration is an excellent place to start, but I also recommend:
- Installing a wireless energy monitor to see your entire home or business power usage in real-time.
- Upgrade all your lights to LED – particularly those tube lights inside display fridges.
- Switch to more sensible forms of heating and cooling.
- Use these energy-saving devices to reduce the energy usage of other appliances.

Electricity usage of a Refrigerator
Refrigerators are one of the most common household appliances and are used to preserve food by keeping it cool, most refrigerators also come with a built-in freezer box for freezing food. Modern refrigerators are very energy efficient compared to older models from a few decades ago. A fridge will use anywhere from 100 to 400 watts depending on size, a large fridge will use about 180 watts or 1575 kWh annually.
This calculator does not account for compressor cycles and other factors which can drastically increase or decrease power usage. You will need to know an average running wattage of your fridge to get an accurate result, if you input the rated wattage you will get a highly inflated result. One way to determine the actual running wattage is to find the daily or annual kWh rating and use that as the baseline for your calculation. For example if the annual kWh rating is 875 kWh, divided by 365 days will give you about 2.4 kWh per day, which means the average wattage (accounting for all factors) is about 100 watts.
Click calculate to find the energy consumption of a refrigerator using 180 Watts for 24 hours a day @ $0.10 per kWh.

Single door vs double door refrigerator power consumption
Many readers of Zelect mailed us and asked about power consumption as people gets confused regarding whether will double door refrigerator increase the power consumption or decrease the power consumption. There is a reason for that confusion to occur. Let’s investigate the reasons and facts in detail. The short answer is single door refrigerator consume less power.
First, double door refrigerator works in frost free mode, where electric fans are used to circulate cool air. Apart from that, double door refrigerator comes in large size of 235 to 295 liters capacity. This large size results in more power consumption. It requires around 30 to 40% more power or electricity.
One interesting fact is in the single door refrigerator to open a freezer, first you need to open the refrigerator main door and then freezer door. Because of frequent opening of door the whole fridge temperature goes up. It requires much electricity to cool down once again.
But the additional power consumed in double door refrigerator to cool down is very high compared to the extra power consumed in frequently opening of the main door of single door refrigerator(to open freezer door). Hence single door refrigerator consume less power and can save lot of electricity bill. Even old refrigerator consumes more energy than new refrigerator.
