Model
Liebherr MF3051
Rank #575 means 574 of the 622 freezer models we track cost less to run each year; the 38th efficiency percentile means it uses less energy for its size than 38% of those models.
What does the Liebherr MF3051 cost to run per year?
Do the math and the Liebherr MF3051's $98/yr puts it at rank #575 of 622, one of the costlier freezer models we track to keep running. It uses 15% less energy than the U.S. federal standard model in its class, which would cost about $113/yr to run, a saving of roughly $15 a year. Adjusted for size, it is only more efficient than 38% of freezer models we track, so part of its running cost comes from its capacity rather than efficiency alone. At 15.2 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 Gaggenau RF491705 at $98/yr runs a little cheaper and the Miele F 2912 Vi at $98/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 Liebherr MF3051's $98/yr adds up to roughly $1372 in electricity alone, before purchase price or repairs.
By the numbers
The Liebherr MF3051 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 $98/yr, here is what the Liebherr MF3051 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Liebherr MF3051 costs about $980. That is roughly $150 less than a standard model in its class, which would run closer to $1130 over the same ten years.
How the Liebherr MF3051 compares
The freezer class we track runs from $25 to $120 a year. At $98/yr, it runs about $23 a year above the class median of $75, and it is about $73 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $113/yr, the Liebherr MF3051 uses 15% less energy.
What drives its running cost
At 15.2 cu ft, the Liebherr MF3051 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. 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 Liebherr MF3051 cheap to run?
Not especially. At $98 a year it ranks #575 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 Liebherr MF3051 cost per month?
Roughly $8.17/mo, spreading the $98/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 528 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $98 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Liebherr MF3051 for its size?
38th 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.
