How Much Does It Cost to Run a Standalone Freezer?
Between $4.61 and $6.34 a month — $56 to $77 a year — for a typical 15 cu ft Energy Star unit at the 2024 US average rate of $0.16/kWh. The low end is a chest freezer, the high end an upright. Peak compressor draw is 80-150W, but it only cycles about a third of the day, so the effective continuous load is 40W for a chest and 55W for an upright.
The calculator below is preloaded with an upright freezer (55W, running 24 hours a day). Own a chest freezer instead? Change the wattage to 40W. Then pick your state to load your local rate.

For perspective...
At $77.09/year, that's about $6 per month — roughly 15 gallons of gas per year.
Effective continuous wattage, not nameplate — see why the nameplate number is wrong for a freezer. Wattage typically falls between 30W (a compact chest) and 100W (a large or aging frost-free upright).
Chest Freezer vs. Upright Freezer Energy Use
At the same capacity, a chest freezer uses roughly 30-40% less electricitythan an upright. The reason is physics, not build quality: cold air is denser than warm air, so it sinks. Lift a chest freezer's lid and the cold stays in the box — only the warmer air at the top spills out. Swing an upright's door open and the cold pours out of the doorway, and the compressor has to re-chill a boxful of room-temperature air. Most uprights are also frost-free, which means a defrost heater periodically adds heat the compressor then has to remove again.
| Size | Chest (kWh/yr) | Upright (kWh/yr) | Chest cost/yr | Upright cost/yr | Use case |
|---|---|---|---|---|---|
| 5 cu ft (compact) | 215 | 295 | $34 | $47 | Apartment / dorm overflow |
| 7 cu ft (small) | 250 | 345 | $40 | $55 | Couple's second freezer |
| 9 cu ft (mid) | 290 | 400 | $46 | $64 | Small family |
| 15 cu ft (typical) | 350 | 480 | $56 | $77 | Most common size; bulk shopping |
| Pre-2010 (15 cu ft) | 600 | 825 | $96 | $132 | Often 1.5-2x a current model |
Chest figures are the Energy Star size tiers used on the chest freezer page. Upright figures apply the door-opening and defrost penalty described above — taken as the ratio of the two effective wattages (55W ÷ 40W, a 37.5% uplift), rounded to the nearest 5 kWh. On a typical 15 cu ft unit that's about $21 a year — the price of reaching a labeled shelf instead of digging to the bottom of a box.
Why the Nameplate Wattage Is Wrong
Yearly cost = annual kWh (from the EnergyGuide sticker) × price per kWh
The wattage printed on a freezer is what the compressor draws while it is running— usually 80-150W. It doesn't run continuously. Once the contents are frozen, it cycles on for only about 25-35% of the day. Multiply nameplate watts by 24 hours and you'll roughly triple the real number.
So this page uses effective continuous wattage: the sticker's annual kWh divided by the 8,760hours in a year. That figure drops straight into the watts × hours calculator above and comes out right.
Worked example (15 cu ft upright, 480 kWh/year, $0.16/kWh): 480 kWh × $0.16 = $77 per year — the same as 55W × 24 h × 365 days.
Yearly Cost by Wattage and Electricity Rate

The 100W column isn't a scare figure — it's what an old frost-free upright in a hot garage realistically draws. At $0.33/kWh that single appliance runs $289 a year.
What Drives the Cost
Age, more than size
A modern 15 cu ft freezer can use less electricity than a 1990s 9 cu ft one. Compressors, insulation, and refrigerants have all improved. If yours pre-dates 2010, the replacement math usually works out on electricity alone — and many utilities pay a $30-$75 rebate to haul the old one away.
Frost-free vs. manual defrost
A frost-free freezer runs a heating element on a timer to melt frost off the coils — then the compressor removes that heat again. You pay twice. Manual-defrost models (nearly all chests, some uprights) skip the cycle entirely in exchange for an annual defrosting.
Where it lives
The EnergyGuide kWh assumes 70°F ambient. A 100°F+ summer garage adds 20-40%. A cold garage causes the opposite problem: standard freezers stop cycling reliably below about 40°F ambient, risking a thaw, so you need a "garage-ready" unit. A 60-70°F basement tracks the sticker most closely.
How full it stays
Frozen food is thermal mass. A 75-90% full freezer holds cold between compressor cycles; a nearly empty one cycles constantly to re-cool air. This matters more for uprights, where each door opening replaces the air anyway. If you can't fill it with food, jugs of water work — fill to ~90% to leave room for expansion.
How to Lower the Cost
Buy the chest if access allows
About $21/year cheaper at 15 cu ft, and cheaper to buy. Choose the upright only if you'll actually use the freezer often enough that digging through a chest would drive you mad.
Set it to 0°F, not colder
0°F is the FDA target for frozen food. Every degree below that costs money and buys nothing. A cheap freezer thermometer tells you where you actually are.
Get it out of the hot garage
Moving a freezer from a 100°F summer garage to a 65°F basement cuts 20-40% of its kWh. It's the single biggest one-time decision you make about a standalone freezer.
Keep it 75-90% full
Frozen food (or jugs of water) holds cold between cycles. A packed freezer runs noticeably less than an empty one — and an empty second freezer is pure loss.
Check the door gasket yearly
Close a dollar bill in the door and tug. If it slides out, the seal is leaking cold 24/7. A replacement gasket is $10-$25 and often recovers 5-10% of the kWh.
Retire pre-2010 units
An old freezer can draw 600-900 kWh/year against 250-400 for a current Energy Star model — $40-$80 a year, every year, for a unit you already own.

Frequently Asked Questions
How much does it cost to run a standalone freezer?
Between about $4.61 and $6.34 a month — $56 to $77 a year — for a typical 15 cu ft Energy Star unit at the 2024 US average rate of $0.16/kWh. The low end is a chest freezer (about 350 kWh/year), the high end an upright (about 480 kWh/year). Compact 5-7 cu ft units run $30-$45/year; an aging pre-2010 freezer can double any of these numbers.
Which uses less electricity, a chest freezer or an upright freezer?
A chest freezer, by roughly 30-40% at the same capacity. Cold air is denser than warm air, so it sinks. Open a chest freezer's lid and the cold stays in the box — only the warmer air at the top spills out. Open an upright and the cold air pours out of the doorway, exactly like a refrigerator, and the compressor has to re-chill a boxful of room-temperature air. Chest freezers also tend to be manual-defrost, avoiding the defrost heater that most frost-free uprights run periodically.
Why does the calculator use 40-55 watts when my freezer says 120 watts?
The nameplate is the compressor's draw while it is running, and the compressor doesn't run continuously. Once the contents are frozen it cycles on only about 25-35% of a 24-hour day. Multiplying nameplate watts by 24 hours would roughly triple the real figure. The effective continuous wattage used here (annual kWh from the EnergyGuide sticker divided by 8,760 hours) is what makes the watts x hours math come out right for an always-plugged-in appliance.
Does a frost-free upright cost more to run than a manual-defrost one?
Yes. A frost-free model runs a heating element on a timer to melt frost off the evaporator coils, then the compressor has to remove that heat again. You're paying twice — once to add heat, once to take it back out. The trade-off is that you never have to empty the freezer and chip out the ice. If you rarely open the freezer and don't mind an annual defrost, a manual-defrost model is the cheaper unit to run.
Is a standalone freezer worth it if I already have a refrigerator?
On electricity alone, a second freezer only pays for itself if it lets you buy food at a discount you'd otherwise miss — bulk meat, a share of a butchered animal, a garden harvest. The freezer itself adds $56-$77 a year to the bill, which is real but modest. Where people get burned is keeping a mostly-empty second freezer running year-round, or leaving a 1990s hand-me-down in the garage where it can quietly cost $100+ a year.
Does putting a standalone freezer in the garage cost more?
Often, and sometimes a lot. The EnergyGuide annual kWh assumes 70°F ambient air. A garage in Phoenix or Houston can sit above 100°F all summer, and the compressor has to work considerably harder to hold 0°F inside — expect 20-40% more kWh than the sticker. The opposite problem shows up in cold climates: standard freezers aren't designed to keep cycling below about 40°F ambient, so an unheated northern garage can let the freezer stop running and the food thaw. Look for a unit sold as "garage-ready" if the space swings either way.
