We’ve been eyeing up mini fridges the last couple of months, there is nothing like having a mini fridge for when you are hosting guests on a deck or even in your finished basement. They use a lot less power than a full size fridge and they are very useful. But how much does it cost to run that mini fridge? First have to answer how many watts does a mini fridge use.

How to calculate power consumption

The process of converting the energy used by an appliance is:

  • Find how many watts per hour the appliance uses.
  • Multiply by hours used in a day to get your daily Watt hours.
  • Divide Watt hours (Wh) by 1000 to get daily Kilowatt hours (kW)
  • Multiply it by the cost of electricity (average is $0.12 per kilowatt) to get the daily cost of the device.

 

What is the energy consumption of a mini fridge

How Many Watts Does a Mini Fridge UseWe will quickly dive into figuring out how many watts a mini fridge uses then we will show you how much your mini fridge will cost you on your power bill based on the watt hours.

A compact fridge or mini fridge is going to vary in wattage used based on its size and the manufacturer. Compact refrigerators range in size from 1.7 cubic foot to 4.5 cubic feet. With the average size of a mini fridge being around the 3.5 cubic foot mark. They are often able to fit under a countertop or in a dorm room.

How much power does a mini fridge use?

There are different types of mini fridges and most of them will range between 50 to 100 Watt hours. With them averaging around 80 to 100 watts per hour. That is with an energy star rating on the appliances. Older mini fridges may use more because they weren’t not build as energy efficient as the newer models.

For simplicity let’s use 100 watts per day. That’s how many watts it uses in an hour. If a fridge is running for 6 hours per day. Usually the fridge runs on a cycle. It will turn on and off periodically through the day if it is kept closed. Then it will use a total of 600 watts or 0.6 kilowatts per day. Keep it plugged in all year long at that usage rate and it will use 219 kW a year. With a 12 cent per kilowatt the operating costs of this small fridge would be $26.28 a year.
As you can see small bar fridges don’t use a lot of power.

Mini Fridge Energy Usage Calculator

We know you probably have a whole bunch of questions so we built this mini fridge power consumption calculator so you can figure out how many watts your mini fridge will use and what it will cost you.
Because let’s be honest, we are all wondering how much this compact fridge will cost us. It’s nice to have a separate place where we can keep our drinks cold and out of the way of our full sized refrigerator but only if the electricity cost makes sense.

How to reduce the power of a mini fridge

You’re going to save money on your compact refrigerator. The easiest way to do that is to unplug it when it’s not in use. Typically these fridges only get used for special occasions unless they are in a dorm room in which case they’re your whole life.

If you find that you are using this on a seasonal basis the best thing you can do to reduce your mini fridges cost is to unplug it. This will reduce the electricity consumption for the time it’s not in use. If you need to plug it in again here is how long it takes for a refrigerator to get cold.

Next we will need to decide how often we are using it.

Knowing the wattage is great. But there is also how frequently it gets used. Of course it will vary depending on if you’re plugged in for a few hours or if you are leaving it plugged in all the time. Remember that if you are plugging it in intermittently that it can take time for a fridge to get cold whether it’s a mini fridge or a full size refrigerator. It’s not like flipping a switch more like a thermostat gently rising to the right temperature.

Another way to reduce the power is to turn down the cold air setting. This will reduce the amount of power it draws and can cut down on your mini fridge costs.
