Kitchenaid KBBX104***
Rank #492 means 491 of the 1,000 refrigerator models we track cost less to run each year; the 39th efficiency percentile means it uses less energy for its size than 39% of those models.
What does the Kitchenaid KBBX104*** cost to run per year?
The Kitchenaid KBBX104*** holds rank #492 of 1,000 on running cost, at about $62 a year, an unremarkable but typical figure for the class. It uses 23% less energy than the U.S. federal standard model in its class, which would cost about $81/yr to run, a saving of roughly $19 a year. Its size-adjusted efficiency percentile of 39 suggests its capacity is doing more work than its efficiency to keep the headline cost down. Counter-depth construction, which this model has, generally means a shallower cabinet and less interior volume than a standard-depth model the same width, a tradeoff worth knowing if you are comparing it on cubic feet.
Immediately around it on the leaderboard, the Midea MRB49B3A** at $62/yr runs a little cheaper and the Avanti RMS551SS at $63/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 KBBX104***'s $62/yr adds up to roughly $744 in electricity alone, before purchase price or repairs.
By the numbers
The Kitchenaid KBBX104*** 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 $62/yr, here is what the Kitchenaid KBBX104*** 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 KBBX104*** costs about $620. That is roughly $190 less than a standard model in its class, which would run closer to $810 over the same ten years.
How the Kitchenaid KBBX104*** compares
The refrigerator class we track runs from $8 to $149 a year. At $62/yr, it runs about $2 a year cheaper than the class median of $64, and it is about $54 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $81/yr, the Kitchenaid KBBX104*** uses 23% less energy.
What drives its running cost
At 9.2 cu ft, the Kitchenaid KBBX104*** 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, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone.
- Counter depth vs standard depth. Standard-depth models generally offer more interior volume per unit of width than counter-depth models, a tradeoff between built-in looks and cubic feet.
- Interior volume. More cubic feet of cold air to maintain generally means a bigger compressor and a higher running-cost figure, even among efficient models.
- Compressor technology. How a compressor cycles, full on/off versus a variable-speed inverter design, is one of the biggest hidden differences behind two fridges with similar cubic feet but different running costs.
- Placement and ventilation. Ventilation clearance around the back and top matters more than most owners expect; a fridge starved of airflow runs its compressor longer to hold the same temperature.
Common questions
Is the Kitchenaid KBBX104*** cheap to run?
Roughly, yes. Its $62/yr figure is close to the class median, ranking #492 of 1,000, neither a bargain nor a splurge on running cost.
How much does the Kitchenaid KBBX104*** cost per month?
About $5.2 a month, which is the $62 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: 336 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $62 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Kitchenaid KBBX104*** for its size?
39th percentile once size is factored in, a fairly typical result for the class.
