Model
Gaggenau RF491705
Rank #574 means 573 of the 622 freezer models we track cost less to run each year; the 71st efficiency percentile means it uses less energy for its size than 71% of those models.
What does the Gaggenau RF491705 cost to run per year?
At $98 a year to run, the Gaggenau RF491705 is among the more expensive freezer models we track to run, ranking #574 of 622. It uses 24% less energy than the U.S. federal standard model in its class, which would cost about $127/yr to run, a saving of roughly $29 a year. Its 71th size-adjusted efficiency percentile is a step ahead of the class median, though not among the very top results. At 19.4 cu ft, it is a large 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 Jenn-Air JBZF*24IGX** at $97/yr runs a little cheaper and the Liebherr MF3051 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 Gaggenau RF491705's $98/yr adds up to roughly $1372 in electricity alone, before purchase price or repairs.

By the numbers
The Gaggenau RF491705 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 Gaggenau RF491705 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Gaggenau RF491705 costs about $980. That is roughly $290 less than a standard model in its class, which would run closer to $1270 over the same ten years.
How the Gaggenau RF491705 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 $127/yr, the Gaggenau RF491705 uses 24% less energy.
What drives its running cost
At 19.4 cu ft, the Gaggenau RF491705 is a large freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up.
- 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 Gaggenau RF491705 cheap to run?
Not especially. At $98 a year it ranks #574 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 Gaggenau RF491705 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 Gaggenau RF491705 for its size?
71st percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
