Model
Fhiaba KS360TST3IU
Rank #794 means 793 of the 1,000 refrigerator models we track cost less to run each year; the 56th efficiency percentile means it uses less energy for its size than 56% of those models.
What does the Fhiaba KS360TST3IU cost to run per year?
The Fhiaba KS360TST3IU costs about $102 a year to run, more than most of the 1,000 refrigerator models we track; it ranks #794. It uses 16% less energy than the U.S. federal standard model in its class, which would cost about $118/yr to run, a saving of roughly $16 a year. Efficiency-wise, once size is accounted for, it sits right around the class median, ahead of 56% of the models we track. 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 Lg LF27NCH10* at $102/yr runs a little cheaper and the Liebherr CBS 2092G at $102/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 Fhiaba KS360TST3IU's $102/yr adds up to roughly $1224 in electricity alone, before purchase price or repairs.
By the numbers
The Fhiaba KS360TST3IU 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 $102/yr, here is what the Fhiaba KS360TST3IU adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Fhiaba KS360TST3IU costs about $1020. That is roughly $160 less than a standard model in its class, which would run closer to $1180 over the same ten years.
How the Fhiaba KS360TST3IU compares
The refrigerator class we track runs from $8 to $149 a year. At $102/yr, it runs about $38 a year above the class median of $64, and it is about $94 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $118/yr, the Fhiaba KS360TST3IU uses 16% less energy.
What drives its running cost
At 19.6 cu ft, the Fhiaba KS360TST3IU is a large refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, and larger refrigerator models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light.
- 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 Fhiaba KS360TST3IU cheap to run?
Its $102/yr running cost, rank #794 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 Fhiaba KS360TST3IU cost per month?
About $8.51 a month, which is the $102 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: 550 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $102 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Fhiaba KS360TST3IU for its size?
56th 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.
