Model
Thermador T24UR925LS
Rank #325 means 324 of the 1,000 refrigerator models we track cost less to run each year; the 28th efficiency percentile means it uses less energy for its size than 28% of those models.
What does the Thermador T24UR925LS cost to run per year?
The Thermador T24UR925LS costs about $51 a year to run, which beats most of the 1,000 refrigerator models we track; it ranks #325. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $57/yr to run, a saving of roughly $6 a year. Efficiency-wise, once size is accounted for, it trails most of the class, ahead of only 28% of the models we track. This class has no published efficiency-factor figure beyond annual kWh itself, so at 5.2 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 Thermador T24UR915LS at $51/yr runs a little cheaper and the Zephyr PRB24C01AS-ADA at $51/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 Thermador T24UR925LS's $51/yr adds up to roughly $612 in electricity alone, before purchase price or repairs.

By the numbers
The Thermador T24UR925LS 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 $51/yr, here is what the Thermador T24UR925LS adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Thermador T24UR925LS costs about $510. That is roughly $60 less than a standard model in its class, which would run closer to $570 over the same ten years.
How the Thermador T24UR925LS compares
The refrigerator class we track runs from $8 to $149 a year. At $51/yr, it runs about $13 a year cheaper than the class median of $64, and it is about $43 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $57/yr, the Thermador T24UR925LS uses 11% less energy.
What drives its running cost
At 5.2 cu ft, the Thermador T24UR925LS is a small refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 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. 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 Thermador T24UR925LS cheap to run?
Yes. Its $51/yr running cost puts it at rank #325 of 1,000, below what most refrigerator models we track cost to run.
How much does the Thermador T24UR925LS cost per month?
About $4.24 a month, which is the $51 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: 274 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $51 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Thermador T24UR925LS for its size?
28th percentile once size is factored in, a fairly typical result for the class.
