Buying guide
What does a mini fridge cost to run?
A typical mini fridge uses roughly 100–350 kWh of electricity per year. At US prices of about $0.13–$0.25 per kWh, that comes to approximately $13–$88 a year to run. The math is simple — annual kWh times your price per kWh — and everything else on this page just shows that calculation with clearly labeled assumptions so you can redo it with your own model and rate.

Our assumptions (edit these for your own case)
- Annual energy use: 100–350 kWh/year — a category range for mini and compact fridges. Your model’s EnergyGuide label has its own figure.
- Electricity price: $0.13–$0.25 per kWh — a range across US regions. Use the rate printed on your electric bill.
- Formula: annual cost = kWh per year × price per kWh.
These are estimates for illustration, not a guarantee. Real usage shifts with room temperature, how often the door opens, how full the fridge is, and how efficient the model is.
The estimate, worked out
Multiply annual kWh by the price per kWh. At the low rate ($0.13) and the high rate ($0.25), three representative usage levels look like this:
| Usage level | kWh / year | At $0.13/kWh | At $0.25/kWh |
|---|---|---|---|
| Efficient small / compact unit | 100 | ~$13/yr | ~$25/yr |
| Mid-range compact with freezer | 200 | ~$26/yr | ~$50/yr |
| Larger / older compact | 350 | ~$46/yr | ~$88/yr |
So a middle-of-the-road compact fridge at ~200 kWh/year lands around $26–$50 a year, and the full plausible span across all levels and rates is roughly $13–$88 a year. We round to whole dollars on purpose — the inputs are ranges, so decimals would imply precision that is not there.
Find your own number in two steps
- Read the kWh/year from the fridge’s yellow EnergyGuide label or spec sheet.
- Multiply it by the price per kWh on your electric bill. That product is your estimated yearly running cost.
Ways to keep the cost down
- Put it somewhere cool and ventilated, away from sun, ovens, and radiators.
- Leave a few inches of clearance behind and above for airflow.
- Do not set it colder than you actually need.
- Keep the door seal clean and close it promptly.
- Right-size it — a smaller unit generally draws less than a larger one with a freezer.

Frequently asked questions
How much does it cost to run a mini fridge per year?
A typical mini fridge uses somewhere around 100–350 kWh per year. At US electricity prices of about $0.13–$0.25 per kWh, that works out to roughly $13–$88 a year. Your actual cost depends on the model, how full and how often it is opened, room temperature, and your local rate.
Where do I find my fridge’s real energy use?
Check the yellow EnergyGuide label or the product’s spec sheet for an estimated kWh-per-year figure, then multiply by the price per kWh on your electric bill. That gives a far more accurate number than any general estimate.
Do mini fridges use a lot of electricity?
Compared with a full-size refrigerator, most mini fridges use relatively little — often a few dollars to a few tens of dollars a year. Larger compact models with a real freezer compartment sit at the higher end of that range.
How can I lower a mini fridge’s running cost?
Keep it in a cool, ventilated spot away from sun and heat sources, leave a few inches of clearance for airflow, do not set it colder than you need, keep the door seal clean, and avoid frequent long door openings. An efficient, right-sized model helps most.
