What does the Forno FFFFD1738-28BLK-LS cost to run per year?

At $83 a year to run, the Forno FFFFD1738-28BLK-LS runs more expensively than most models in its class, ranking #413 of 622 freezer models we track. 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. Once capacity is factored in, its efficiency percentile of 44 is fairly typical for the class, neither a standout nor a laggard. At 14 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 Elisii DFFFD1738-28WHT-LS at $83/yr runs a little cheaper and the Forno FFFFD1738-28LS 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 Forno FFFFD1738-28BLK-LS's $83/yr adds up to roughly $1162 in electricity alone, before purchase price or repairs.

What it costs you over time

Running cost is an every-year number, so it compounds. At $83/yr, here is what the Forno FFFFD1738-28BLK-LS adds up to before purchase price, water, or repairs enter the math.

1 year$83
5 years$415
10 years$830

Left running for a decade at today's US average rate, the Forno FFFFD1738-28BLK-LS 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 Forno FFFFD1738-28BLK-LS 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 Forno FFFFD1738-28BLK-LS uses 16% less energy.

What drives its running cost

At 14 cu ft, the Forno FFFFD1738-28BLK-LS 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 Forno FFFFD1738-28BLK-LS cheap to run?

Not especially. At $83 a year it ranks #413 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 Forno FFFFD1738-28BLK-LS cost per month?

Roughly $6.94/mo, spreading the $83/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 449 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $83 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.

How efficient is the Forno FFFFD1738-28BLK-LS 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.
