How much does a small fridge cost to run?
A small fridge can look cheap to run, but many compact models are less efficient than people expect. The real cost depends on wattage, runtime, room temperature, and tariff.
Short answer
The easiest way to estimate it is to use a mini fridge or small refrigerator calculator with your own price per kWh. In many cases, size alone does not guarantee a low bill.
