Model
Arctic Wind AUFW210ETH-LK
Rank #463 means 462 of the 622 freezer models we track cost less to run each year; the 89th efficiency percentile means it uses less energy for its size than 89% of those models.
What does the Arctic Wind AUFW210ETH-LK cost to run per year?
The Arctic Wind AUFW210ETH-LK costs about $91 a year to run, more than most of the 622 freezer models we track; it ranks #463. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $102/yr to run, a saving of roughly $11 a year. Its size-adjusted efficiency percentile of 89 sits well above the class median, a clearly above-average efficiency result. This class has no published efficiency-factor figure beyond annual kWh itself, so at 21 cu ft (the class spans 1.1 to 23), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Arctic Wind AUFSS210ETH-LK at $91/yr runs a little cheaper and the Artt ATUF21ES at $91/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A freezer typically stays in service for somewhere around 14 years; over that span, the Arctic Wind AUFW210ETH-LK's $91/yr adds up to roughly $1274 in electricity alone, before purchase price or repairs.

By the numbers
The Arctic Wind AUFW210ETH-LK normalized against its whole class, so each figure means something.
What it costs you over time
Running cost is an every-year number, so it compounds. At $91/yr, here is what the Arctic Wind AUFW210ETH-LK adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Arctic Wind AUFW210ETH-LK costs about $910. That is roughly $110 less than a standard model in its class, which would run closer to $1020 over the same ten years.
How the Arctic Wind AUFW210ETH-LK compares
The freezer class we track runs from $25 to $120 a year. At $91/yr, it runs about $16 a year above the class median of $75, and it is about $66 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $102/yr, the Arctic Wind AUFW210ETH-LK uses 10% less energy.
What drives its running cost
At 21 cu ft, the Arctic Wind AUFW210ETH-LK is a large freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, and larger freezer models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light.
- Interior volume. As with refrigerators, more cubic feet of frozen storage generally means a bigger compressor and a higher annual energy figure.
- Insulation and defrost type. Better-insulated cabinets lose less cold to the surrounding room, and frost-free (automatic-defrost) freezers run a periodic heating element that a manual-defrost model does not.
- Chest vs upright design. Door orientation affects how much cold air escapes per opening: top-opening chest designs generally hold cold better than front-opening upright ones.
Common questions
Is the Arctic Wind AUFW210ETH-LK cheap to run?
Its $91/yr running cost, rank #463 of 622, is above what most freezer models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Arctic Wind AUFW210ETH-LK cost per month?
About $7.61 a month, which is the $91 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 492 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $91 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Arctic Wind AUFW210ETH-LK for its size?
89th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
