Model
Lg LDNTH862*
Rank #64 means 63 of the 709 dishwasher models we track cost less to run each year; the 95th efficiency percentile means it uses less energy for its size than 95% of those models.
What does the Lg LDNTH862* cost to run per year?
Few dishwasher models we track cost less to run than the Lg LDNTH862*: about $41 a year, rank #64 of 709. It uses 28.3% less energy than the U.S. federal standard model in its class, which would cost about $57/yr to run, a saving of roughly $16 a year. Normalized for capacity, it ranks ahead of 95% of dishwasher models we track on efficiency, an exceptional showing for the class. At 16 place settings, it is a large dishwasher for the class, which runs 2 to 18 place settings; 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 Lg LDNTH753* at $41/yr runs a little cheaper and the Lg LDNTM545* at $41/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A dishwasher typically stays in service for somewhere around 9 years; over that span, the Lg LDNTH862*'s $41/yr adds up to roughly $369 in electricity alone, before purchase price or repairs.

By the numbers
The Lg LDNTH862* 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 $41/yr, here is what the Lg LDNTH862* 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 LDNTH862* costs about $410. That is roughly $160 less than a standard model in its class, which would run closer to $570 over the same ten years.
How the Lg LDNTH862* compares
The dishwasher class we track runs from $15 to $45 a year. At $41/yr, it runs about $3 a year cheaper than the class median of $44, and it is about $26 a year more than the cheapest dishwasher to run at $15. Against the US federal standard model for its class at about $57/yr, the Lg LDNTH862* uses 28.3% less energy.
What drives its running cost
At 16 place settings, the Lg LDNTH862* is a large dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, 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.
- Place-setting capacity. A larger dishwasher heats more water per cycle, so bigger capacity generally means a higher annual energy figure, independent of how efficient the unit is.
- Water heating. The booster heater that brings water up to sanitizing temperature is usually the single largest electrical load in a dishwasher's cycle.
- Cycle length and drying method. Cycle selection, eco versus heavy, air-dry versus heated-dry, moves real running cost more than most owners realize for a given capacity.
Common questions
Is the Lg LDNTH862* cheap to run?
Yes, relatively. At $41 a year it ranks #64 of 709 dishwasher models we track, in the cheaper part of its class to run.
How much does the Lg LDNTH862* cost per month?
Roughly $3.4/mo, spreading the $41/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 220 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $41 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg LDNTH862* for its size?
95th 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.
