Model
Lg LF29H8330*
Rank #995 means 994 of the 1,000 refrigerator models we track cost less to run each year; the 58th efficiency percentile means it uses less energy for its size than 58% of those models.
What does the Lg LF29H8330* cost to run per year?
Rank #995 of 1,000 puts the Lg LF29H8330* among the priciest refrigerator models we track to keep running, at roughly $146 a year. It uses 5% less energy than the U.S. federal standard model in its class, which would cost about $152/yr to run, a saving of roughly $6 a year. Efficiency-wise, once size is accounted for, it sits right around the class median, ahead of 58% of the models we track. This class has no published efficiency-factor figure beyond annual kWh itself, so at 28.6 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 Midea MRF29D3AWW at $145/yr runs a little cheaper and the Lg LF29S8330* at $146/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 LF29H8330*'s $146/yr adds up to roughly $1752 in electricity alone, before purchase price or repairs. At rank #995 of 1,000, it sits at the very top of the cost range for its class, among the single priciest models we track to run.
Also sold as: Lg LF29S8330*, Lg LH29S8565*.
By the numbers
The Lg LF29H8330* 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 $146/yr, here is what the Lg LF29H8330* 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 LF29H8330* costs about $1460. That is roughly $60 less than a standard model in its class, which would run closer to $1520 over the same ten years.
How the Lg LF29H8330* compares
The refrigerator class we track runs from $8 to $149 a year. At $146/yr, it runs about $82 a year above the class median of $64, and it is about $138 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $152/yr, the Lg LF29H8330* uses 5% less energy.
What drives its running cost
At 28.6 cu ft, the Lg LF29H8330* is a large refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, among refrigerator models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal.
- 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 Lg LF29H8330* cheap to run?
Its $146/yr running cost, rank #995 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 LF29H8330* cost per month?
About $12.14 a month, which is the $146 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: 785 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $146 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg LF29H8330* for its size?
58th 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.
