Model
Lg LRSOC2306*
Rank #903 means 902 of the 1,000 refrigerator models we track cost less to run each year; the 54th efficiency percentile means it uses less energy for its size than 54% of those models.
What does the Lg LRSOC2306* cost to run per year?
The Lg LRSOC2306* costs about $120 a year to run, sitting well up the cheapest-to-run leaderboard, rank #903 of 1,000. It uses 5% less energy than the U.S. federal standard model in its class, which would cost about $125/yr to run, a saving of roughly $5 a year. Its 54th size-adjusted efficiency percentile is unremarkable, close to what a typical model in the class scores. At 22.5 cu ft, it is a large refrigerator for the class, which runs 1.2 to 31.7 cu ft; size and efficiency are the two levers behind the figure above, and this dataset does not carry a separate efficiency-factor column for this class.
Immediately around it on the leaderboard, the Samsung RF25C5551** at $119/yr runs a little cheaper and the Samsung RF28T5A01** at $120/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 LRSOC2306*'s $120/yr adds up to roughly $1440 in electricity alone, before purchase price or repairs.
By the numbers
The Lg LRSOC2306* 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 $120/yr, here is what the Lg LRSOC2306* 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 LRSOC2306* costs about $1200. That is roughly $50 less than a standard model in its class, which would run closer to $1250 over the same ten years.
How the Lg LRSOC2306* compares
The refrigerator class we track runs from $8 to $149 a year. At $120/yr, it runs about $56 a year above the class median of $64, and it is about $112 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $125/yr, the Lg LRSOC2306* uses 5% less energy.
What drives its running cost
At 22.5 cu ft, the Lg LRSOC2306* 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. Cubic feet of interior volume is the first thing that scales a fridge's running cost up or down, before compressor quality even enters the picture.
- Counter depth vs standard depth. Counter-depth models sit flush with cabinets but usually hold less interior volume than a standard-depth model of the same width, which can nudge the per-cubic-foot running cost either way.
- Compressor technology. Newer variable-speed (inverter) compressors modulate output instead of cycling fully on and off, which tends to use less energy for the same cooling job than an older fixed-speed compressor.
- Placement and ventilation. A fridge pushed tight against a wall or cabinet, or standing next to an oven or in direct sun, works harder to shed the heat its compressor produces, which can push real-world cost above the published figure.
Common questions
Is the Lg LRSOC2306* cheap to run?
Not especially. At $120 a year it ranks #903 of 1,000 refrigerator models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Lg LRSOC2306* cost per month?
Roughly $9.98/mo, spreading the $120/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 645 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $120 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg LRSOC2306* for its size?
54th 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.
