Model
Lg LBNC15251U
Rank #655 means 654 of the 1,000 refrigerator models we track cost less to run each year; the 53rd efficiency percentile means it uses less energy for its size than 53% of those models.
What does the Lg LBNC15251U cost to run per year?
Ranking #655 of 1,000, the Lg LBNC15251U sits in the pricier half of its class to run, at about $79 a year. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $89/yr to run, a saving of roughly $10 a year. Adjusted for size, it is more efficient than 53% of refrigerator models we track, a middling result. At 14.7 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 Kenmore 896.61362420 at $79/yr runs a little cheaper and the Hisense HRB148N6A*E at $79/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 LBNC15251U's $79/yr adds up to roughly $948 in electricity alone, before purchase price or repairs.
By the numbers
The Lg LBNC15251U 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 $79/yr, here is what the Lg LBNC15251U 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 LBNC15251U costs about $790. That is roughly $100 less than a standard model in its class, which would run closer to $890 over the same ten years.
How the Lg LBNC15251U compares
The refrigerator class we track runs from $8 to $149 a year. At $79/yr, it runs about $15 a year above the class median of $64, and it is about $71 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $89/yr, the Lg LBNC15251U uses 11% less energy.
What drives its running cost
At 14.7 cu ft, the Lg LBNC15251U 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 LBNC15251U cheap to run?
Not especially. At $79 a year it ranks #655 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 LBNC15251U cost per month?
Roughly $6.57/mo, spreading the $79/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 425 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $79 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg LBNC15251U for its size?
53rd 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.
