Model
Lg LDNPM654*
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 LDNPM654* cost to run per year?
Few dishwasher models we track cost less to run than the Lg LDNPM654*: 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 LDNPM545* at $41/yr runs a little cheaper and the Lg LDNPQ445* 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 LDNPM654*'s $41/yr adds up to roughly $369 in electricity alone, before purchase price or repairs.

By the numbers
The Lg LDNPM654* 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 LDNPM654* 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 LDNPM654* 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 LDNPM654* 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 LDNPM654* uses 28.3% less energy.
What drives its running cost
At 16 place settings, the Lg LDNPM654* is a large dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, and larger dishwasher models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light.
- 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 LDNPM654* 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 LDNPM654* 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 LDNPM654* 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.
