How Much Electricity Does a Refrigerator Use?
So how much electricity does a refrigerator use? A standard full-size, frost-free refrigerator has a rated draw of roughly 725 watts, but because the compressor cycles on and off rather than running non-stop, its real average draw over a day is much lower than that peak figure. Use the calculator below with your refrigerator's wattage and your own electricity rate — an “effective hours” figure of around 8 is a reasonable stand-in for a full day of cycling.

What affects how much electricity a refrigerator uses
Size is the most obvious factor: a larger fridge has more interior volume to keep cold. Age and efficiency rating matter a lot too — older units, especially pre-ENERGY STAR models, can use significantly more electricity than current ones of the same size. How and where it's placed affects the compressor's workload: coils caked in dust, a fridge pushed against a wall with no airflow behind it, or one sitting next to a heat source like an oven or in direct sunlight all make it run harder and longer. Door seal condition and how often the door is opened also factor in, since every opening lets cold air out and forces the compressor to catch back up.
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. Varies by size, age, and efficiency rating. We review this figure periodically and update it if the source changes; last checked September 2026.
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 — see below for why that distinction matters.
How much does it cost to run a refrigerator?
Because the compressor cycles on and off rather than running continuously, a refrigerator's real average draw is well below its peak wattage — often somewhere around a third of the rated figure over a full day. Use the calculator above with a lower "effective hours" figure (many people use 8 hours as a rough stand-in for a full day of cycling) alongside your own rate for a realistic estimate.
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 typical wattage figures and the numbers 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.
