Model
Kalamera KCF-100E
Rank #5 means 4 of the 622 freezer models we track cost less to run each year; the 17th efficiency percentile means it uses less energy for its size than 17% of those models.
What does the Kalamera KCF-100E cost to run per year?
The Kalamera KCF-100E costs about $32 a year to run, a figure that only a handful of the 622 freezer models we track can beat, rank #5. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $36/yr to run, a saving of roughly $4 a year. Its 17th size-adjusted efficiency percentile is well below the class median, worth weighing against the raw cost figure above. At 3.4 cu ft, it is a small 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 Marathon MCF36W-1 at $31/yr runs a little cheaper and the Marathon MCF35W-1 at $32/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 Kalamera KCF-100E's $32/yr adds up to roughly $448 in electricity alone, before purchase price or repairs. At rank #5 of 622, it is one of the single cheapest freezer models we track to run, in the top one percent on cost.
By the numbers
The Kalamera KCF-100E 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 $32/yr, here is what the Kalamera KCF-100E adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Kalamera KCF-100E costs about $320. That is roughly $40 less than a standard model in its class, which would run closer to $360 over the same ten years.
How the Kalamera KCF-100E compares
The freezer class we track runs from $25 to $120 a year. At $32/yr, it runs about $43 a year cheaper than the class median of $75, and it is about $7 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $36/yr, the Kalamera KCF-100E uses 10% less energy.
What drives its running cost
At 3.4 cu ft, the Kalamera KCF-100E is a small freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, and smaller freezer models generally cost less to run for the same job, all else being equal.
- 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 Kalamera KCF-100E cheap to run?
Yes, relatively. At $32 a year it ranks #5 of 622 freezer models we track, in the cheaper part of its class to run.
How much does the Kalamera KCF-100E cost per month?
Roughly $2.66/mo, spreading the $32/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 172 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $32 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Kalamera KCF-100E for its size?
17th 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.
