Model
Criterion CUF21C1W
Rank #484 means 483 of the 622 freezer models we track cost less to run each year; the 96th efficiency percentile means it uses less energy for its size than 96% of those models.
What does the Criterion CUF21C1W cost to run per year?
At $92 a year to run, the Criterion CUF21C1W runs more expensively than most models in its class, ranking #484 of 622 freezer models we track. 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 $10 a year. Efficiency-wise, once its capacity is accounted for, it edges out 96% of the class, about as strong a result as this ranking produces. At 21.2 cu ft, it is a large freezer for the class, which runs 1.1 to 23 cu ft; size and efficiency are the two levers behind the figure above, and this dataset does not carry a separate efficiency-factor column for this class.
Immediately around it on the leaderboard, the Black+Decker BUC2120M* at $92/yr runs a little cheaper and the Criterion CUF21M2* at $92/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 CUF21C1W's $92/yr adds up to roughly $1288 in electricity alone, before purchase price or repairs.

By the numbers
The Criterion CUF21C1W 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 $92/yr, here is what the Criterion CUF21C1W 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 CUF21C1W costs about $920. That is roughly $100 less than a standard model in its class, which would run closer to $1020 over the same ten years.
How the Criterion CUF21C1W compares
The freezer class we track runs from $25 to $120 a year. At $92/yr, it runs about $17 a year above the class median of $75, and it is about $67 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 Criterion CUF21C1W uses 10% less energy.
What drives its running cost
At 21.2 cu ft, the Criterion CUF21C1W is a large freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up.
- Interior volume. Cubic feet of frozen storage is the first lever behind a freezer's running cost, ahead of insulation or defrost type.
- Insulation and defrost type. Two freezers of the same size can differ meaningfully on running cost based on insulation quality and whether they run an automatic-defrost heater.
- Chest vs upright design. Chest freezers open from the top, so cold air, which sinks, stays inside when the lid opens; upright freezers lose more cold air per door opening for a similar capacity.
Common questions
Is the Criterion CUF21C1W cheap to run?
Not especially. At $92 a year it ranks #484 of 622 freezer models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Criterion CUF21C1W cost per month?
Roughly $7.63/mo, spreading the $92/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 493 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $92 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Criterion CUF21C1W for its size?
96th 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.
