A standard full-size, frost-free refrigerator has a rated draw of roughly 725 watts, but the compressor cycles on and off, so its real average draw is much lower. The most accurate figure is the yearly kWh on the fridge's yellow EnergyGuide label: kWh per year × your rate = cost per year. The sample label in EnergySage's refrigerator wattage guide shows 630 kWh a year, which works out to about $104 a year, or $8.66 a month, at 16.5 cents per kWh. If you only know the wattage, the watts and hours fields still work, but the common rule of counting 8 running hours a day can come out several times higher than a label figure. For example, 725 W × 8 hours is 5.8 kWh a day, or about 2,100 kWh a year.
| Method | Yearly kWh | Yearly cost at 16.5¢ |
|---|---|---|
| EnergyGuide sample label | 630 | about $104 |
| 725 W × 8 hours a day | about 2,100 | about $349 |
What affects how much electricity a refrigerator uses
- Size: a larger fridge has more interior volume to keep cold.
- Age and efficiency: older units, especially pre-ENERGY STAR models, can use much more electricity than current ones of the same size.
- Placement and coils: dusty coils, no airflow behind the fridge, or a spot next to an oven or in direct sunlight all make the compressor run harder and longer.
- Door seal and openings: every opening lets cold air out and forces the compressor to catch back up, and a worn seal leaks cold air all the time.
How to reduce your refrigerator's electricity use
- Keep the condenser coils clean and dust-free
- Avoid overpacking or significantly underpacking the fridge
- Check that door seals close tightly, with no gaps
- Keep it away from direct sunlight and heat sources like an oven
Typical wattage figure: roughly 725 W (frost-free, 16 cu ft reference unit). Source: DOE-developed appliance energy table, reproduced by Virginia Cooperative Extension (Virginia Tech), publication BSE-301. The compressor cycles on and off rather than running continuously, so actual average draw is well below this peak figure. Annual-use example: the sample EnergyGuide label in EnergySage's refrigerator wattage guide (630 kWh a year). Use varies by size, age, and efficiency rating. We review these figures periodically and update them if a source changes; last checked October 2026. Cedrick Reese built this refrigerator cost calculator and rechecks these figures against the sources above.
Frequently asked questions
How many watts does a refrigerator use?
A standard frost-free refrigerator (around 16 cubic feet) has a rated draw of roughly 725 watts, according to a DOE-developed appliance energy table reproduced by Virginia Cooperative Extension. That's the compressor's running wattage, not its average draw, which is why a yearly kWh figure is the better guide to cost.
How much does it cost to run a refrigerator?
Use the yearly kWh from the yellow EnergyGuide label: kWh per year × your rate = cost per year. A fridge labeled at 630 kWh a year costs about $104 a year, or $8.66 a month, at 16.5 cents per kWh. Multiplying the rated wattage by an assumed number of running hours tends to overstate the cost, because the compressor cycles on and off.
Does a refrigerator use a lot of electricity compared to other appliances?
It runs continuously, 24/7, unlike most appliances, so even a moderate wattage adds up over a full month. It's typically one of the larger steady contributors to a home's electricity use, alongside heating, cooling, and water heating.
How can I reduce how much electricity my refrigerator uses?
Keep the condenser coils clean and free of dust, since dirty coils make the compressor work harder. Avoid overpacking the fridge (airflow matters) and avoid underpacking it too much either, since an empty fridge loses cold air faster when opened. Check the door seals for a tight fit, and keep it out of direct sunlight or right next to the oven, both of which force the compressor to run more.
This page provides estimates based on the EnergyGuide or wattage figures you enter. A refrigerator's real average draw is significantly lower than its peak rated wattage because the compressor cycles on and off; actual cost depends on your specific model, age, and conditions.
