A standalone freezer runs ~80–200W with the compressor cycling roughly a third of the day.

A chest freezer looks like it should cost a fortune to run — it's a big insulated box humming in the garage 24/7 — but the compressor isn't actually on the whole time. At a typical 100 watts, it cycles on and off to hold temperature, running roughly a third of the day rather than continuously, which is why the real draw averages out closer to a light bulb than an appliance.
That cycling behavior is also why two identical-looking freezers can cost very differently to run: a tight-sealing lid and a full load of frozen food act like thermal mass, so the compressor kicks on less often. An old chest freezer with a worn gasket, or one that's half-empty and gets opened a lot, can push power draw toward the 200-watt end of the range and double what a well-sealed, well-stocked unit costs — the setting on the dial matters far less than how often that door has to fight its way back to temperature.
What drives the cost of running a chest freezer
- Compressor duty cycle, not constant draw — the unit cycles on/off to hold temperature, so real-world runtime averages well under 24 hours even though it's always plugged in
- How full it is — a fully stocked freezer holds cold better and needs less compressor time than a half-empty one
- Age and seal condition — an older unit or a worn door gasket lets cold escape, pushing the compressor toward the high end of its wattage range
How to cut it
- Keep it full — pack empty space with water jugs or ice packs; a full freezer holds cold longer and the compressor cycles less often
- Check and replace the door/lid gasket if you can see light or feel air leaking around the seal
- Keep it somewhere temperate — an unheated garage or shed that swings hot in summer makes the compressor work harder than a basement would
- Set the thermostat to 0°F (the safe standard) rather than colder — over-cooling below that wastes energy without any food-safety benefit

Common questions
How much does it cost to run a chest freezer per month?
On the assumption shown above — 100W running 38% of 24 h — a chest freezer costs about $5.04 a month, or $60.45 a year, at $0.1816/kWh. That price is the U.S. average; set your own rate and usage above and the figure updates.
How is that worked out?
Running power x hours connected x the share of that time the motor actually runs. At 100W running 38% of 24 h that is 0.91 kWh a day, which at $0.1816/kWh costs $0.17 a day.
How can I cut the cost of running a chest freezer?
Keep it full — pack empty space with water jugs or ice packs; a full freezer holds cold longer and the compressor cycles less often As a worked example: getting the run share down from 38% to 30.4% takes it from $60.45 to $48.36 a year, about $12.09 less.
Does a chest freezer cost more to run than an upright freezer?
Usually less. Chest freezers open from the top, so cold air (which is heavier) stays inside the box when you lift the lid instead of spilling out the way it does when you open an upright's front door. That means less cold loss per opening and less work for the compressor to recover, which is a big part of why chest freezers tend to be the cheaper of the two to run.
Does an empty chest freezer cost more to run than a full one?
Yes, a little. Frozen food acts as thermal mass that holds its temperature, so a full freezer needs less compressor time to recover after the lid opens. If you're running one mostly empty, packing it with water-filled jugs is a low-cost way to close some of that gap.
