Freezer vs. Refrigerator Cost: Which Is Cheaper to Run?
A 15 cu ft chest freezer costs about $56 a year to run. A full-size refrigerator costs $64 to $120. So yes — a chest freezer is cheaper to run than almost any refrigerator, saving roughly $32 a year against a typical top-freezer fridge, even though it holds 0°F inside instead of 37°F. An upright freezer ($77/year) breaks that rule: it costs more than an Energy Star fridge.
The calculator below is preloaded with a 15 cu ft chest freezer against a typical top-freezer refrigerator at the 2024 US average rate of $0.16/kWh. Swap in your own units, your EnergyGuide sticker numbers, and your state's rate.

Annual kWh figures are Energy Star typicals; replace them with the number on your unit's yellow EnergyGuide sticker for an exact answer. Effective wattage is annual kWh divided by 8,760 hours — an always-on average, not the nameplate draw of a compressor that only runs about a third of the day. Monthly figures are a twelfth of the year. Garage placement applies a 30% uplift.
Annual Running Cost by Model Type
Energy Star typical annual kWh for each unit, converted to cost at $0.16/kWh. Effective wattage is the annual kWh spread across all 8,760 hours of the year — the number to use for an appliance that never switches off, rather than the nameplate figure on the compressor.

Chest freezer and refrigerator tiers match the figures on cost to run a chest freezer and cost to run a refrigerator. Upright figures apply the 30-40% door-and-defrost penalty derived on cost to run a standalone freezer.
Why the Colder Box Costs Less
A freezer holds 0°F against a 70°F room. A fridge holds 37°F against the same room — less than half the temperature difference to fight. On thermodynamics alone the freezer should lose. It wins anyway, for four reasons that have nothing to do with how cold it gets inside.
A lid, not a door
Cold air is denser than warm air, so it sinks. Lift a chest freezer's lid and the cold sits in the box; only the warmer air at the top spills out. Swing a fridge door open and the cold pours out of the doorway, and the compressor has to re-chill a boxful of room-temperature air. This is the single reason an upright freezer uses 30-40% more electricity than a chest freezer of identical capacity.
Opened a few times a week, not a few times an hour
Nobody browses a chest freezer. You open it to put a month of food in and to take a package out. A kitchen refrigerator is opened dozens of times a day, and every one of those openings is a small refrigeration job the compressor has to redo.
No defrost heater, no ice maker, no dispenser
Most chest freezers are manual-defrost: you chip the ice out once a year and that's the whole system. Frost-free fridges and uprights run a heating element on a timer to melt frost off the coils — and then the compressor has to remove that heat again. You pay twice. Add an ice maker, a through-door water dispenser, interior lights, and the anti-sweat heaters some doors use, and a large fridge carries a stack of small loads a chest freezer simply doesn't have.
Full stays cold, empty does not
A packed freezer is mostly thermal mass. Frozen food holds its temperature between compressor cycles, so a 75-90% full chest freezer barely runs. A refrigerator is mostly air by volume, and air holds no cold at all. This is also why a mostly-empty second fridge is such a bad deal: it's paying to chill air.
The honest caveat: divide by capacity and the gap mostly closes. The chest freezer uses about 23 kWh per cubic foot per year; a 19.5 cu ft refrigerator uses about 21 kWh per cubic foot if it's Energy Star and 28if it isn't. Per unit of volume they're in the same range — the freezer is doing harder work, and its hardware is good enough to roughly break even on it. What decides the annual bill is that the freezer is a smaller box you open far less often.
The Garage Second Fridge vs. a Chest Freezer
This is where the comparison stops being academic. The old refrigerator that got demoted to the garage when the kitchen was remodeled is usually the single most expensive appliance in the house per unit of food stored — and it is usually storing frozen meat.
A pre-2010 fridge uses around 1100 kWh/year on the sticker, and the sticker assumes a 70°F room. A garage that sits above 100°F in summer adds roughly 30% — call it $229 a year. A 15 cu ft chest freezer in that same garage, carrying the same ambient penalty, costs $73 a year.
Swapping the garage fridge for a chest freezer saves about $156a year — and buys you more frozen storage than the fridge's freezer compartment ever had.
Two conditions. First, you have to actually unplug and recycle the old fridge, not move it to the basement — many utilities pay $50-$100 to haul it away. Second, this only works if what you store is frozen. A freezer will not hold your drinks.
Cost Per Year by Electricity Rate

At $0.33/kWh — Hawaii, parts of New England — the chest freezer costs $116 a year and the French-door fridge $248. The gap between them widens to $132, from $64 at the US average rate.

Frequently Asked Questions
Is a chest freezer cheaper to run than a refrigerator?
Yes. A typical 15 cu ft chest freezer uses about 350 kWh a year — roughly $56 at the 2024 US average rate of $0.16/kWh. A full-size refrigerator uses 400-750 kWh a year, or $64-$120. Against the typical installed fridge, the chest freezer saves about $32 a year. It wins despite holding 0°F instead of 37°F, because it's a smaller, better-sealed box that gets opened far less often and has no ice maker, dispenser, or defrost heater to feed.
Why does a freezer cost less to run than a fridge when it's much colder inside?
Because the temperature you hold inside is only one term in the equation, and it's not the dominant one. A chest freezer's lid keeps the cold in when you open it — cold air is denser, so it sits in the box instead of pouring out. A fridge door dumps its cold air every time it swings, and a fridge gets opened dozens of times a day against a freezer's few times a week. A full-size fridge is also a bigger box with more door surface, and most run an automatic defrost heater, an ice maker, interior lights, and sometimes anti-sweat heaters in the door — loads the compressor then has to remove again. A chest freezer has none of that.
What is the freezer vs refrigerator electricity cost difference per month?
At the US average rate, a 15 cu ft chest freezer costs about $4.67 a month and a typical top-freezer refrigerator about $7.33 — a difference of roughly $2.67 a month. An upright freezer costs about $6.40 a month, and a large French-door fridge about $10.00. Your rate moves all of these proportionally: at Hawaii's $0.33/kWh, the same chest freezer costs $9.63 a month.
Does an upright freezer cost more to run than a refrigerator?
It can. A 15 cu ft upright freezer uses about 480 kWh a year ($77), while an Energy Star top-freezer refrigerator uses about 400 kWh ($64). So an upright freezer beside an efficient modern fridge is the more expensive appliance, even though the fridge is much larger. Uprights lose the chest freezer's two advantages at once: the door dumps cold air like a fridge door, and most uprights are frost-free, which means a defrost heater periodically adds heat the compressor has to pull back out.
Is it cheaper to run a chest freezer than a second fridge in the garage?
Much cheaper, if all you keep in it is frozen food. A pre-2010 refrigerator uses around 1100 kWh a year, and a hot garage adds roughly 30% on top of the EnergyGuide sticker, which assumes 70°F ambient — call it $229 a year. A 15 cu ft chest freezer in that same garage runs about $73. Swapping one for the other saves roughly $156 a year. The catch is obvious: a freezer won't hold your beer and leftovers. If the second fridge is mostly storing frozen meat anyway, the swap is one of the largest single-appliance savings available in most homes.
Per cubic foot, is a freezer really more efficient than a fridge?
Not really — and that's the honest version of the headline. A 15 cu ft chest freezer uses about 23 kWh per cubic foot per year. A 19.5 cu ft refrigerator uses about 21 kWh per cubic foot if it's Energy Star, or 28 if it's a standard model. Per unit of volume they're in the same range, which makes sense: the freezer holds a much bigger temperature difference against the room. The chest freezer wins the annual bill because it's a smaller box with a lid instead of a door, opened a fraction as often, with none of the ice-maker and defrost hardware. Size and habits decide this, not thermodynamics.
Does the wattage on the back of my freezer tell me what it costs?
No, and it will roughly triple your estimate if you use it. The nameplate shows what the compressor draws while it is running, and a freezer's compressor only cycles about 25-35% of a 24-hour day once the contents are frozen. Use the annual kWh figure on the yellow EnergyGuide sticker instead. Divide it by 8,760 hours to get the effective continuous wattage — that's the number that makes watts x hours arithmetic come out right for an appliance that never switches off.
