Model
Summit DW18SS4
Rank #74 means 73 of the 709 dishwasher models we track cost less to run each year; the 11th efficiency percentile means it uses less energy for its size than 11% of those models.
What does the Summit DW18SS4 cost to run per year?
At $41 a year to run, the Summit DW18SS4 is among the cheapest dishwasher models we track, ranking #74 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. Its 11th size-adjusted efficiency percentile is well below the class median, worth weighing against the raw cost figure above. At 8 place settings, it is a small 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 Miele G 5482 SCVi SL at $41/yr runs a little cheaper and the Whirlpool UDPS5118SP 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 Summit DW18SS4's $41/yr adds up to roughly $369 in electricity alone, before purchase price or repairs.

By the numbers
The Summit DW18SS4 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 Summit DW18SS4 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Summit DW18SS4 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 Summit DW18SS4 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 Summit DW18SS4 uses 28.3% less energy.
What drives its running cost
At 8 place settings, the Summit DW18SS4 is a small dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, and smaller dishwasher models generally cost less to run for the same job, all else being equal.
- 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 Summit DW18SS4 cheap to run?
Yes, relatively. At $41 a year it ranks #74 of 709 dishwasher models we track, in the cheaper part of its class to run.
How much does the Summit DW18SS4 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 Summit DW18SS4 for its size?
11th percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
