Model
Lg LB12C2000*
Rank #380 means 379 of the 1,000 refrigerator models we track cost less to run each year; the 76th efficiency percentile means it uses less energy for its size than 76% of those models.
What does the Lg LB12C2000* cost to run per year?
Do the math and the Lg LB12C2000*'s $55/yr puts it at rank #380 of 1,000, on the cheaper side of the class. It uses 34% less energy than the U.S. federal standard model in its class, which would cost about $84/yr to run, a saving of roughly $29 a year. Adjusted for size, it is more efficient than 76% of refrigerator models we track, a solidly above-average result. At 12.1 cu ft, it is a mid-size 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 FRTE1026AB at $55/yr runs a little cheaper and the Wood'S WFF100S at $55/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 LB12C2000*'s $55/yr adds up to roughly $660 in electricity alone, before purchase price or repairs.
By the numbers
The Lg LB12C2000* 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 $55/yr, here is what the Lg LB12C2000* 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 LB12C2000* costs about $550. That is roughly $290 less than a standard model in its class, which would run closer to $840 over the same ten years.
How the Lg LB12C2000* compares
The refrigerator class we track runs from $8 to $149 a year. At $55/yr, it runs about $9 a year cheaper than the class median of $64, and it is about $47 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $84/yr, the Lg LB12C2000* uses 34% less energy.
What drives its running cost
At 12.1 cu ft, the Lg LB12C2000* is a mid-size refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, putting it squarely in the middle of the class on the size lever that drives most of the cost.
- 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 LB12C2000* cheap to run?
Yes, relatively. At $55 a year it ranks #380 of 1,000 refrigerator models we track, in the cheaper part of its class to run.
How much does the Lg LB12C2000* cost per month?
Roughly $4.61/mo, spreading the $55/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 298 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $55 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg LB12C2000* for its size?
76th percentile once size is factored in, a fairly typical result for the class.
