Model
Jennair JBWFNR18RX
Rank #24 means 23 of the 1,000 refrigerator models we track cost less to run each year; the 93rd efficiency percentile means it uses less energy for its size than 93% of those models.
What does the Jennair JBWFNR18RX cost to run per year?
The Jennair JBWFNR18RX costs about $28 a year to run, a figure that only a handful of the 1,000 refrigerator models we track can beat, rank #24. It uses 30% less energy than the U.S. federal standard model in its class, which would cost about $41/yr to run, a saving of roughly $13 a year. Efficiency-wise, once capacity is accounted for, it beats 93% of the class, a solidly strong result rather than a size-driven fluke. Its listing marks it counter-depth, meaning it sits nearly flush with surrounding cabinets rather than protruding a few extra inches like a standard-depth model; that shallower body usually means less interior volume for the same footprint.
Immediately around it on the leaderboard, the Fisher & Paykel RS2474S3**# at $28/yr runs a little cheaper and the Liebherr HW 8000 at $29/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 Jennair JBWFNR18RX's $28/yr adds up to roughly $336 in electricity alone, before purchase price or repairs.
By the numbers
The Jennair JBWFNR18RX 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 $28/yr, here is what the Jennair JBWFNR18RX adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Jennair JBWFNR18RX costs about $280. That is roughly $130 less than a standard model in its class, which would run closer to $410 over the same ten years.
How the Jennair JBWFNR18RX compares
The refrigerator class we track runs from $8 to $149 a year. At $28/yr, it runs about $36 a year cheaper than the class median of $64, and it is about $20 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $41/yr, the Jennair JBWFNR18RX uses 30% less energy.
What drives its running cost
At 8 cu ft, the Jennair JBWFNR18RX 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, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class.
- 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 Jennair JBWFNR18RX cheap to run?
Yes, relatively. At $28 a year it ranks #24 of 1,000 refrigerator models we track, in the cheaper part of its class to run.
How much does the Jennair JBWFNR18RX cost per month?
Roughly $2.37/mo, spreading the $28/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 153 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $28 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Jennair JBWFNR18RX for its size?
93rd 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.
