Model
Kitchenaid KUCT524SSB**
Rank #674 means 673 of the 1,000 refrigerator models we track cost less to run each year; the 7th efficiency percentile means it uses less energy for its size than 7% of those models.
What does the Kitchenaid KUCT524SSB** cost to run per year?
The Kitchenaid KUCT524SSB** costs about $82 a year to run, more than most of the 1,000 refrigerator models we track; it ranks #674. It uses 12% less energy than the U.S. federal standard model in its class, which would cost about $91/yr to run, a saving of roughly $9 a year. Efficiency-wise, once size is accounted for, it lags most of the class, ahead of only 7% of the models we track. This class has no published efficiency-factor figure beyond annual kWh itself, so at 4.3 cu ft (the class spans 1.2 to 31.7), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Lg LT18S1200* at $82/yr runs a little cheaper and the Thermador T24UC905DP at $82/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 KUCT524SSB**'s $82/yr adds up to roughly $984 in electricity alone, before purchase price or repairs.
Also sold as: Thermador T24UC905DP.
By the numbers
The Kitchenaid KUCT524SSB** 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 $82/yr, here is what the Kitchenaid KUCT524SSB** 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 KUCT524SSB** costs about $820. That is roughly $90 less than a standard model in its class, which would run closer to $910 over the same ten years.
How the Kitchenaid KUCT524SSB** compares
The refrigerator class we track runs from $8 to $149 a year. At $82/yr, it runs about $18 a year above the class median of $64, and it is about $74 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $91/yr, the Kitchenaid KUCT524SSB** uses 12% less energy.
What drives its running cost
At 4.3 cu ft, the Kitchenaid KUCT524SSB** is a small refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is.
- 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.
- 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.
- 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 KUCT524SSB** cheap to run?
Its $82/yr running cost, rank #674 of 1,000, is above what most refrigerator models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Kitchenaid KUCT524SSB** cost per month?
About $6.84 a month, which is the $82 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: 442 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $82 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Kitchenaid KUCT524SSB** for its size?
7th 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.
