How much does it cost to run a mini refrigerator?
A typical mini refrigerator draws about 150 watts. Used 8 hours a day, that works out to roughly $0.20 per day, $6.21 per month, and $74.46 per year on an average electricity rate of 17¢ per kWh. Mini fridges consume significantly less energy than full-size models but run continuously throughout the day.

Based on 438 kWh per year. Adjust the price per kWh to match your latest electricity bill for an exact figure.
The number that matters most is your own electricity rate. Rates range from under 11¢ per kWh in some regions to over 30¢ in others, so the same mini refrigerator can cost two or three times as much depending on where you live. Enter your exact rate in the calculator above to get a figure tailored to your bill.
In the kitchen the mini refrigerator is typically used in short, frequent bursts rather than left on all day, so total run time matters more than peak wattage. Small changes — batching tasks, matching the appliance to the job — add up over a year of daily cooking.
At 150 watts, the mini refrigerator is a low-power device, so its cost per hour is small. The annual total only becomes meaningful if it runs for many hours a day — which is exactly why long-running low-wattage devices are easy to overlook on a bill.
Over a full year this mini refrigerator uses about 438 kWh of electricity and is responsible for roughly 175.2 kg of CO₂ emissions on an average grid. Because it runs more or less year-round, even a small reduction in daily use carries straight through to a lower annual total.
To put the draw in everyday terms, one hour of running this mini refrigerator uses about as much electricity as charging a smartphone 13 times. It is a rough comparison, but it makes an abstract wattage figure easier to picture.
If this mini refrigerator is one you use daily, even small efficiency gains compound. Cutting its usage or wattage by 20% would save around $14.89 every year — money that an efficient replacement can recover over its lifetime.
