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.
Hours Used Per Day: Enter how many hours the device is being used on average per day, if the power consumption is lower than 1 hour per day enter as a decimal. (For example: 30 minutes per day is 0.5)
Power Use (Watts): Enter the average power consumption of the device in watts.
Price (kWh): Enter the cost you are paying on average per kilowatt hour, our caculators use the default value of 0.10 or 10 cents. To find an exact price check your electricity bill or take a look at Global Electricity Prices.
If you are using an old fridge we highly recommend you upgrade to a more efficient modern model, advances in the past 15-20 years have reduced the energy use of refrigeration. If your refrigerator has been purchased in the last 10 years then buying a new one may not give you a significant improvement.
