Model
Forno FFFFD1722-28BLK-RS
Rank #215 means 214 of the 622 freezer models we track cost less to run each year; the 56th efficiency percentile means it uses less energy for its size than 56% of those models.
What does the Forno FFFFD1722-28BLK-RS cost to run per year?
At roughly $73 a year to run, ranking #215 of 622, the Forno FFFFD1722-28BLK-RS costs less than the typical freezer model we track. 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. Capacity-normalized, it ranks ahead of 56% 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 13.6 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 Forno FFFFD1722-28BLK-LS at $73/yr runs a little cheaper and the Forno FFFFD1722-28LS 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 Forno FFFFD1722-28BLK-RS's $73/yr adds up to roughly $1022 in electricity alone, before purchase price or repairs.
Also sold as: Elisii DECVC138W.
By the numbers
The Forno FFFFD1722-28BLK-RS 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 Forno FFFFD1722-28BLK-RS adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Forno FFFFD1722-28BLK-RS 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 Forno FFFFD1722-28BLK-RS 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 Forno FFFFD1722-28BLK-RS uses 10% less energy.
What drives its running cost
At 13.6 cu ft, the Forno FFFFD1722-28BLK-RS is a mid-size freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone.
- 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 Forno FFFFD1722-28BLK-RS cheap to run?
Yes. Its $73/yr running cost puts it at rank #215 of 622, below what most freezer models we track cost to run.
How much does the Forno FFFFD1722-28BLK-RS cost per month?
About $6.05 a month, which is the $73 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: 391 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $73 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Forno FFFFD1722-28BLK-RS for its size?
56th percentile once size is factored in, a fairly typical result for the class.
