Model
Lg LF27BCH54*
Rank #892 means 891 of the 1,000 refrigerator models we track cost less to run each year; the 79th efficiency percentile means it uses less energy for its size than 79% of those models.
What does the Lg LF27BCH54* cost to run per year?
Rank #892 of 1,000 puts the Lg LF27BCH54* among the pricier refrigerator models we track to keep running, at roughly $117 a year. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $129/yr to run, a saving of roughly $12 a year. Efficiency-wise, once size is accounted for, it edges out 79% of the class, a modestly above-average showing. It is a counter-depth model, built shallower to sit flush with kitchen cabinets, a design choice that typically trades away some interior volume (and so some running-cost headroom) for the built-in look.
Immediately around it on the leaderboard, the Thermador T42BT120NS at $117/yr runs a little cheaper and the Lg LRFLC2706* at $117/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 Lg LF27BCH54*'s $117/yr adds up to roughly $1404 in electricity alone, before purchase price or repairs.
Also sold as: Lg LRFLC2706*.
By the numbers
The Lg LF27BCH54* 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 $117/yr, here is what the Lg LF27BCH54* adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Lg LF27BCH54* costs about $1170. That is roughly $120 less than a standard model in its class, which would run closer to $1290 over the same ten years.
How the Lg LF27BCH54* compares
The refrigerator class we track runs from $8 to $149 a year. At $117/yr, it runs about $53 a year above the class median of $64, and it is about $109 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $129/yr, the Lg LF27BCH54* uses 10% less energy.
What drives its running cost
At 26.5 cu ft, the Lg LF27BCH54* 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. 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 Lg LF27BCH54* cheap to run?
Its $117/yr running cost, rank #892 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 Lg LF27BCH54* cost per month?
About $9.77 a month, which is the $117 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: 632 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $117 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg LF27BCH54* for its size?
79th 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.
