Epic ECF50W-1

Rank #13 means 12 of the 622 freezer models we track cost less to run each year; the 34th efficiency percentile means it uses less energy for its size than 34% of those models.

Our read

What does the Epic ECF50W-1 cost to run per year?

Few freezer models we track undercut the Epic ECF50W-1 on cost; at about $34 a year it holds rank #13 of 622. It uses 15% less energy than the U.S. federal standard model in its class, which would cost about $40/yr to run, a saving of roughly $6 a year. Adjusted for size, it is only more efficient than 34% of freezer models we track, so part of its running cost comes from its capacity rather than efficiency alone. At 4.9 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 Omnimax 3730-922 at $32/yr runs a little cheaper and the Marathon MCF50W-1 at $34/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 ECF50W-1's $34/yr adds up to roughly $476 in electricity alone, before purchase price or repairs.

Also sold as: Marathon MCF50W-1.

What it costs you over time

Running cost is an every-year number, so it compounds. At $34/yr, here is what the Epic ECF50W-1 adds up to before purchase price, water, or repairs enter the math.

1 year$34
5 years$170
10 years$340

Left running for a decade at today's US average rate, the Epic ECF50W-1 costs about $340. That is roughly $60 less than a standard model in its class, which would run closer to $400 over the same ten years.

How the Epic ECF50W-1 compares

The freezer class we track runs from $25 to $120 a year. At $34/yr, it runs about $41 a year cheaper than the class median of $75, and it is about $9 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $40/yr, the Epic ECF50W-1 uses 15% less energy.

What drives its running cost

At 4.9 cu ft, the Epic ECF50W-1 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 Epic ECF50W-1 cheap to run?

Yes, relatively. At $34 a year it ranks #13 of 622 freezer models we track, in the cheaper part of its class to run.

How much does the Epic ECF50W-1 cost per month?

Roughly $2.85/mo, spreading the $34/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 184 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $34 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.

How efficient is the Epic ECF50W-1 for its size?

34th 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.
