Model
Danby Designer DUF140E1WDD
Rank #237 means 236 of the 622 freezer models we track cost less to run each year; the 63rd efficiency percentile means it uses less energy for its size than 63% of those models.
What does the Danby Designer DUF140E1WDD cost to run per year?
The Danby Designer DUF140E1WDD is a relatively cheap runner for its class: about $73 a year, rank #237 of 622. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $81/yr to run, a saving of roughly $8 a year. Once capacity is factored in, its 63th efficiency percentile puts it ahead of most peers in its class. At 13.8 cu ft, it is a mid-size 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 Danby Designer DUF140E1* at $73/yr runs a little cheaper and the Element EUF14CDB* at $73/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 Danby Designer DUF140E1WDD's $73/yr adds up to roughly $1022 in electricity alone, before purchase price or repairs.
Also sold as: Alpha RDVC138WE.
By the numbers
The Danby Designer DUF140E1WDD 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 $73/yr, here is what the Danby Designer DUF140E1WDD adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Danby Designer DUF140E1WDD costs about $730. That is roughly $80 less than a standard model in its class, which would run closer to $810 over the same ten years.
How the Danby Designer DUF140E1WDD compares
The freezer class we track runs from $25 to $120 a year. At $73/yr, it runs about $2 a year cheaper than the class median of $75, and it is about $48 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $81/yr, the Danby Designer DUF140E1WDD uses 10% less energy.
What drives its running cost
At 13.8 cu ft, the Danby Designer DUF140E1WDD is a mid-size freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, putting it squarely in the middle of the class on the size lever that drives most of the cost.
- 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 Danby Designer DUF140E1WDD cheap to run?
Yes, relatively. At $73 a year it ranks #237 of 622 freezer models we track, in the cheaper part of its class to run.
How much does the Danby Designer DUF140E1WDD cost per month?
Roughly $6.09/mo, spreading the $73/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 394 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $73 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Danby Designer DUF140E1WDD for its size?
63rd percentile once size is factored in, a fairly typical result for the class.
