Model
Elisii DFFFD1738-28LS
Rank #413 means 412 of the 622 freezer models we track cost less to run each year; the 44th efficiency percentile means it uses less energy for its size than 44% of those models.
What does the Elisii DFFFD1738-28LS cost to run per year?
The Elisii DFFFD1738-28LS costs about $83 a year to run, more than most of the 622 freezer models we track; it ranks #413. It uses 16% less energy than the U.S. federal standard model in its class, which would cost about $97/yr to run, a saving of roughly $14 a year. Capacity-normalized, it ranks ahead of 44% of freezer models we track, right in the class's middle band. This class has no published efficiency-factor figure beyond annual kWh itself, so at 14 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 Elisii DFFFD1738-28BLK-LS at $83/yr runs a little cheaper and the Elisii DFFFD1738-28WHT-LS at $83/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 Elisii DFFFD1738-28LS's $83/yr adds up to roughly $1162 in electricity alone, before purchase price or repairs.

By the numbers
The Elisii DFFFD1738-28LS 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 $83/yr, here is what the Elisii DFFFD1738-28LS adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Elisii DFFFD1738-28LS costs about $830. That is roughly $140 less than a standard model in its class, which would run closer to $970 over the same ten years.
How the Elisii DFFFD1738-28LS compares
The freezer class we track runs from $25 to $120 a year. At $83/yr, it runs about $8 a year above the class median of $75, and it is about $58 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $97/yr, the Elisii DFFFD1738-28LS uses 16% less energy.
What drives its running cost
At 14 cu ft, the Elisii DFFFD1738-28LS is a mid-size freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class.
- 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 Elisii DFFFD1738-28LS cheap to run?
Its $83/yr running cost, rank #413 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 Elisii DFFFD1738-28LS cost per month?
About $6.94 a month, which is the $83 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: 449 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $83 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Elisii DFFFD1738-28LS for its size?
44th 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.
