Model
Liebherr C7620
Rank #388 means 387 of the 1,000 refrigerator models we track cost less to run each year; the 88th efficiency percentile means it uses less energy for its size than 88% of those models.
What does the Liebherr C7620 cost to run per year?
At $57 a year to run, the Liebherr C7620 runs cheaper than most models in its class, ranking #388 of 1,000 refrigerator models we track. It uses 37% less energy than the U.S. federal standard model in its class, which would cost about $89/yr to run, a saving of roughly $32 a year. Once capacity is factored in, it outperforms 88% of the refrigerator models we track on efficiency, not just on headline running cost. It is a counter-depth model, built shallower to sit flush with kitchen cabinets, a design choice that typically trades away some interior volume (and so some running-cost headroom) for the built-in look.
Immediately around it on the leaderboard, the Unique UNQ-310L W TM at $56/yr runs a little cheaper and the Frigidaire FFUV2126AW at $57/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A refrigerator typically stays in service for somewhere around 12 years; over that span, the Liebherr C7620's $57/yr adds up to roughly $684 in electricity alone, before purchase price or repairs.
By the numbers
The Liebherr C7620 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 $57/yr, here is what the Liebherr C7620 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 C7620 costs about $570. That is roughly $320 less than a standard model in its class, which would run closer to $890 over the same ten years.
How the Liebherr C7620 compares
The refrigerator class we track runs from $8 to $149 a year. At $57/yr, it runs about $7 a year cheaper than the class median of $64, and it is about $49 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $89/yr, the Liebherr C7620 uses 37% less energy.
What drives its running cost
At 15 cu ft, the Liebherr C7620 is a mid-size refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, putting it squarely in the middle of the class on the size lever that drives most of the cost.
- Counter depth vs standard depth. Counter-depth models sit flush with cabinets but usually hold less interior volume than a standard-depth model of the same width, which can nudge the per-cubic-foot running cost either way.
- Interior volume. Cubic feet of interior volume is the first thing that scales a fridge's running cost up or down, before compressor quality even enters the picture.
- Compressor technology. Newer variable-speed (inverter) compressors modulate output instead of cycling fully on and off, which tends to use less energy for the same cooling job than an older fixed-speed compressor.
- Placement and ventilation. A fridge pushed tight against a wall or cabinet, or standing next to an oven or in direct sun, works harder to shed the heat its compressor produces, which can push real-world cost above the published figure.
Common questions
Is the Liebherr C7620 cheap to run?
Yes, relatively. At $57 a year it ranks #388 of 1,000 refrigerator models we track, in the cheaper part of its class to run.
How much does the Liebherr C7620 cost per month?
Roughly $4.72/mo, spreading the $57/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 305 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $57 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Liebherr C7620 for its size?
88th percentile once size is factored in, a fairly typical result for the class.
