Model
Crosley XUF21DM****
Rank #541 means 540 of the 622 freezer models we track cost less to run each year; the 97th efficiency percentile means it uses less energy for its size than 97% of those models.
What does the Crosley XUF21DM**** cost to run per year?
The Crosley XUF21DM**** costs about $92 a year to run, well up the cost table for its class at rank #541 of 622. 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. Size-adjusted, this model beats 97% of freezer models we track on efficiency, a standout even among the class's efficient models. This class has no published efficiency-factor figure beyond annual kWh itself, so at 21.3 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 Mora MFU210N6AWE at $92/yr runs a little cheaper and the Ge FUF21DL**** 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 Crosley XUF21DM****'s $92/yr adds up to roughly $1288 in electricity alone, before purchase price or repairs.
Also sold as: Ge FUF21DL****.
By the numbers
The Crosley XUF21DM**** 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 Crosley XUF21DM**** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Crosley XUF21DM**** 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 Crosley XUF21DM**** 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 Crosley XUF21DM**** uses 10% less energy.
What drives its running cost
At 21.3 cu ft, the Crosley XUF21DM**** 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. 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 Crosley XUF21DM**** cheap to run?
Its $92/yr running cost, rank #541 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 Crosley XUF21DM**** cost per month?
About $7.66 a month, which is the $92 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: 495 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $92 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Crosley XUF21DM**** for its size?
97th 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.
