Model
Criterion CUF66C1W
Rank #123 means 122 of the 622 freezer models we track cost less to run each year; the 23rd efficiency percentile means it uses less energy for its size than 23% of those models.
What does the Criterion CUF66C1W cost to run per year?
The Criterion CUF66C1W holds rank #123 of 622 on running cost, at about $54 a year, a genuinely cheap result for the class. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $61/yr to run, a saving of roughly $7 a year. Size-adjusted, this model trails most of its class on efficiency, ahead of just 23% of freezer models we track. This class has no published efficiency-factor figure beyond annual kWh itself, so at 6.6 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 Marathon MUF65BLS at $54/yr runs a little cheaper and the Vitara VLUF0660EW at $54/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 Criterion CUF66C1W's $54/yr adds up to roughly $756 in electricity alone, before purchase price or repairs.

By the numbers
The Criterion CUF66C1W 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 $54/yr, here is what the Criterion CUF66C1W adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Criterion CUF66C1W costs about $540. That is roughly $70 less than a standard model in its class, which would run closer to $610 over the same ten years.
How the Criterion CUF66C1W compares
The freezer class we track runs from $25 to $120 a year. At $54/yr, it runs about $21 a year cheaper than the class median of $75, and it is about $29 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $61/yr, the Criterion CUF66C1W uses 10% less energy.
What drives its running cost
At 6.6 cu ft, the Criterion CUF66C1W is a small freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture.
- 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 Criterion CUF66C1W cheap to run?
Yes. Its $54/yr running cost puts it at rank #123 of 622, below what most freezer models we track cost to run.
How much does the Criterion CUF66C1W cost per month?
About $4.52 a month, which is the $54 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: 292 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $54 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Criterion CUF66C1W for its size?
23rd percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
