Model
Conserv FR2000WREV
Rank #448 means 447 of the 622 freezer models we track cost less to run each year; the 85th efficiency percentile means it uses less energy for its size than 85% of those models.
What does the Conserv FR2000WREV cost to run per year?
The Conserv FR2000WREV costs about $89 a year to run, more than most of the 622 freezer models we track; it ranks #448. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $99/yr to run, a saving of roughly $10 a year. Its size-adjusted efficiency percentile of 85 means the low running cost is not just a function of size; it is genuinely efficient for its class. This class has no published efficiency-factor figure beyond annual kWh itself, so at 20.2 cu ft (the class spans 1.1 to 23), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Conserv FR2000SREV at $89/yr runs a little cheaper and the Gaggenau RF471705 at $89/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 Conserv FR2000WREV's $89/yr adds up to roughly $1246 in electricity alone, before purchase price or repairs.

By the numbers
The Conserv FR2000WREV 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 $89/yr, here is what the Conserv FR2000WREV adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Conserv FR2000WREV costs about $890. That is roughly $100 less than a standard model in its class, which would run closer to $990 over the same ten years.
How the Conserv FR2000WREV compares
The freezer class we track runs from $25 to $120 a year. At $89/yr, it runs about $14 a year above the class median of $75, and it is about $64 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $99/yr, the Conserv FR2000WREV uses 10% less energy.
What drives its running cost
At 20.2 cu ft, the Conserv FR2000WREV is a large freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, and larger freezer models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light.
- Interior volume. As with refrigerators, more cubic feet of frozen storage generally means a bigger compressor and a higher annual energy figure.
- Insulation and defrost type. Better-insulated cabinets lose less cold to the surrounding room, and frost-free (automatic-defrost) freezers run a periodic heating element that a manual-defrost model does not.
- Chest vs upright design. Door orientation affects how much cold air escapes per opening: top-opening chest designs generally hold cold better than front-opening upright ones.
Common questions
Is the Conserv FR2000WREV cheap to run?
Its $89/yr running cost, rank #448 of 622, is above what most freezer models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Conserv FR2000WREV cost per month?
About $7.41 a month, which is the $89 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 479 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $89 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Conserv FR2000WREV for its size?
85th 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.
