Model
Kitchenaid KBBL306ESS**
Rank #861 means 860 of the 1,000 refrigerator models we track cost less to run each year; the 54th efficiency percentile means it uses less energy for its size than 54% of those models.
What does the Kitchenaid KBBL306ESS** cost to run per year?
At $111 a year to run, the Kitchenaid KBBL306ESS** is among the more expensive refrigerator models we track to run, ranking #861 of 1,000. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $122/yr to run, a saving of roughly $11 a year. Once capacity is factored in, its efficiency percentile of 54 is fairly typical for the class, neither a standout nor a laggard. 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 Kitchenaid KBB*336S**** at $111/yr runs a little cheaper and the Kitchenaid KRSC336R**** at $111/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 Kitchenaid KBBL306ESS**'s $111/yr adds up to roughly $1332 in electricity alone, before purchase price or repairs.

By the numbers
The Kitchenaid KBBL306ESS** 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 $111/yr, here is what the Kitchenaid KBBL306ESS** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Kitchenaid KBBL306ESS** costs about $1110. That is roughly $110 less than a standard model in its class, which would run closer to $1220 over the same ten years.
How the Kitchenaid KBBL306ESS** compares
The refrigerator class we track runs from $8 to $149 a year. At $111/yr, it runs about $47 a year above the class median of $64, and it is about $103 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $122/yr, the Kitchenaid KBBL306ESS** uses 10% less energy.
What drives its running cost
At 20.9 cu ft, the Kitchenaid KBBL306ESS** is a large refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 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.
- 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 Kitchenaid KBBL306ESS** cheap to run?
Not especially. At $111 a year it ranks #861 of 1,000 refrigerator 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 Kitchenaid KBBL306ESS** cost per month?
Roughly $9.26/mo, spreading the $111/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 599 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $111 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Kitchenaid KBBL306ESS** for its size?
54th 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.
