How this is calculated
- Annual energy use is the figure ENERGY STAR lists for this model under typical test conditions. It is not measured in your home.
- Yearly cost = annual kWh × your rate. Monthly cost is the yearly cost divided by 12, a flat average. Five-year cost keeps the rate constant; prices will change.
- Statewide averages are not your utility’s tariff. Use your bill’s rate for a closer number.
- We do not estimate watts or hourly cost: the source data does not include them.

Frequently asked questions
How much electricity does the Liebherr MF 3661 use?
ENERGY STAR lists 535 kWh per year under typical test conditions, which is calculated with U.S. Department of Energy test procedures. Your use will differ with how often the lid or door is opened, the room temperature and how full the freezer is kept.
How much does it cost to run?
At statewide average residential prices, the listed annual use costs about $68.05 in Louisiana and $256.80 in Hawaii (EIA, 2026-07). Your own utility rate may be different; enter it in the calculator.
How does the Liebherr MF 3661 compare with similar models?
Among 234 ENERGY STAR certified upright freezer models with a similar adjusted volume, it ranks 188th lowest in annual energy use. Its 535 kWh per year is 9% above the median of 493 kWh.
What does adjusted volume mean?
ENERGY STAR's adjusted volume counts the freezer compartment more heavily than the fresh-food compartment, because freezers need more energy per cubic foot. It is the size measure behind the federal energy standards. This model lists 33.3 ft³ adjusted volume and 18.9 ft³ total volume.
How does it compare with the federal standard?
ENERGY STAR lists this model as using 22% less energy than the federal standard for its product class. That percentage is published by ENERGY STAR and is not recalculated here.
