Model
Lg LS27H3230*
Rank #927 means 926 of the 1,000 refrigerator models we track cost less to run each year; the 73rd efficiency percentile means it uses less energy for its size than 73% of those models.
What does the Lg LS27H3230* cost to run per year?
The Lg LS27H3230* costs about $124 a year to run, sitting well up the cheapest-to-run leaderboard, rank #927 of 1,000. It uses 8% less energy than the U.S. federal standard model in its class, which would cost about $134/yr to run, a saving of roughly $10 a year. Its 73th size-adjusted efficiency percentile is a step ahead of the class median, though not among the very top results. At 26.6 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 Frigidaire GRFC2353A* at $124/yr runs a little cheaper and the Thermador T48IT100NP at $124/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 LS27H3230*'s $124/yr adds up to roughly $1488 in electricity alone, before purchase price or repairs.
By the numbers
The Lg LS27H3230* 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 $124/yr, here is what the Lg LS27H3230* 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 LS27H3230* costs about $1240. That is roughly $100 less than a standard model in its class, which would run closer to $1340 over the same ten years.
How the Lg LS27H3230* compares
The refrigerator class we track runs from $8 to $149 a year. At $124/yr, it runs about $60 a year above the class median of $64, and it is about $116 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $134/yr, the Lg LS27H3230* uses 8% less energy.
What drives its running cost
At 26.6 cu ft, the Lg LS27H3230* 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.
- 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 LS27H3230* cheap to run?
Not especially. At $124 a year it ranks #927 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 LS27H3230* cost per month?
Roughly $10.36/mo, spreading the $124/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 670 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $124 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg LS27H3230* for its size?
73rd 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.
