Model
Jenn-Air JBZF*18IGX**
Rank #439 means 438 of the 622 freezer models we track cost less to run each year; the 17th efficiency percentile means it uses less energy for its size than 17% of those models.
What does the Jenn-Air JBZF*18IGX** cost to run per year?
At about $85 a year, the Jenn-Air JBZF*18IGX** costs more to run than most freezer models we track, rank #439 of 622. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $93/yr to run, a saving of roughly $8 a year. Size-adjusted, this model ranks near the bottom of its class on efficiency, ahead of just 17% of freezer models we track. This class has no published efficiency-factor figure beyond annual kWh itself, so at 9 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 Jenn-Air ALOVE18FLC0* at $85/yr runs a little cheaper and the Frigidaire GRDF1911A* at $86/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 Jenn-Air JBZF*18IGX**'s $85/yr adds up to roughly $1190 in electricity alone, before purchase price or repairs.

By the numbers
The Jenn-Air JBZF*18IGX** 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 $85/yr, here is what the Jenn-Air JBZF*18IGX** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Jenn-Air JBZF*18IGX** costs about $850. That is roughly $80 less than a standard model in its class, which would run closer to $930 over the same ten years.
How the Jenn-Air JBZF*18IGX** compares
The freezer class we track runs from $25 to $120 a year. At $85/yr, it runs about $10 a year above the class median of $75, and it is about $60 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $93/yr, the Jenn-Air JBZF*18IGX** uses 10% less energy.
What drives its running cost
At 9 cu ft, the Jenn-Air JBZF*18IGX** is a small freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture.
- 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 Jenn-Air JBZF*18IGX** cheap to run?
Its $85/yr running cost, rank #439 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 Jenn-Air JBZF*18IGX** cost per month?
About $7.1 a month, which is the $85 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: 459 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $85 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Jenn-Air JBZF*18IGX** for its size?
17th 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.
