It’s true that a garage refrigerator works much harder to maintain proper temperature and this will cause an increase in your utility bill. How much of an increase depends upon a variety of factors such as:
- How full of food your fridge is kept
- The age of the refrigerator
- The condition of the door seals
- The variance of external temperature
- KW cost in your local
Refrigerators built prior to 1993 could use as much as 3 times the energy than a newer Energy Star Certified fridge.
My personal experience is $5-$10 a month cost to run my garage refrigerator, and she’s an old beast! I view the additional expense a small price to pay for the convenience I receive.

The energy cost calculator shows how much money you could save by upgrading your refrigerator to a newer Energy Star rated model.
