Model
Epic ECF36W-1
Rank #3 means 2 of the 622 freezer models we track cost less to run each year; the 19th efficiency percentile means it uses less energy for its size than 19% of those models.
What does the Epic ECF36W-1 cost to run per year?
Almost nothing we track in this class costs less to run than the Epic ECF36W-1: about $31 a year, rank #3 of 622. It uses 13% less energy than the U.S. federal standard model in its class, which would cost about $36/yr to run, a saving of roughly $5 a year. Adjusted for size, it is only more efficient than 19% of freezer models we track, so its headline cost is mostly a function of its capacity rather than efficiency. 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 Liebherr UF3651 at $29/yr runs a little cheaper and the Marathon MCF36W-1 at $31/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 Epic ECF36W-1's $31/yr adds up to roughly $434 in electricity alone, before purchase price or repairs. At rank #3 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 Epic ECF36W-1 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 $31/yr, here is what the Epic ECF36W-1 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Epic ECF36W-1 costs about $310. That is roughly $50 less than a standard model in its class, which would run closer to $360 over the same ten years.
How the Epic ECF36W-1 compares
The freezer class we track runs from $25 to $120 a year. At $31/yr, it runs about $44 a year cheaper than the class median of $75, and it is about $6 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 Epic ECF36W-1 uses 13% less energy.
What drives its running cost
At 3.4 cu ft, the Epic ECF36W-1 is a small freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture.
- 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 Epic ECF36W-1 cheap to run?
Yes, relatively. At $31 a year it ranks #3 of 622 freezer models we track, in the cheaper part of its class to run.
How much does the Epic ECF36W-1 cost per month?
Roughly $2.58/mo, spreading the $31/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 167 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $31 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Epic ECF36W-1 for its size?
19th 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.
