How Much Does It Cost to Run a Mini Fridge?
A mini fridge draws little while running, but running 24/7/365 still puts it ahead of most gadgets on annual cost. At the US-average rate of 16.5¢/kWh, running a mini fridge costs about $8.42/month ($101.06/year) at typical use. Adjust the watts, hours, and your rate below for your exact number.

Cost = power (kW) × hours × days × your rate. Defaults are typical values — enter your appliance's actual watts (often on a label) and your real rate for a precise figure.
How much electricity does a mini fridge use?
At 70 W for 24 hours a day, a mini fridge uses about 1.7 kWh per day — roughly 51 kWh per month and 613 kWh per year. That's about 6% of the 863 kWh the average US home uses in a month. Energy use is the same everywhere — only the price per kWh changes your bill.

Measure what a mini fridge really costs you
The estimate above uses typical wattage and hours. A plug-in energy meter logs the kilowatt-hours this appliance actually uses — leave it in for a week, multiply by your rate, and the estimate becomes a measurement. A whole-home monitor does the same for every circuit at once, but its sensors install inside the panel.
