Model
Summit ADADW24B
Rank #174 means 173 of the 709 dishwasher models we track cost less to run each year; the 77th efficiency percentile means it uses less energy for its size than 77% of those models.
What does the Summit ADADW24B cost to run per year?
Among the 709 dishwasher models we track, the Summit ADADW24B sits in the below-average-cost group, rank #174, at roughly $43 a year. It uses 23.8% less energy than the U.S. federal standard model in its class, which would cost about $57/yr to run, a saving of roughly $14 a year. Capacity-normalized, it ranks ahead of 77% of dishwasher models we track, a reasonably strong result for the class. This class has no published efficiency-factor figure beyond annual kWh itself, so at 15 place settings (the class spans 2 to 18), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Summit ADADW18W at $43/yr runs a little cheaper and the Summit ADADW24NT at $43/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 ADADW24B's $43/yr adds up to roughly $387 in electricity alone, before purchase price or repairs.

By the numbers
The Summit ADADW24B 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 $43/yr, here is what the Summit ADADW24B 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 ADADW24B costs about $430. That is roughly $140 less than a standard model in its class, which would run closer to $570 over the same ten years.
How the Summit ADADW24B compares
The dishwasher class we track runs from $15 to $45 a year. At $43/yr, it runs about $1 a year cheaper than the class median of $44, and it is about $28 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 ADADW24B uses 23.8% less energy.
What drives its running cost
At 15 place settings, the Summit ADADW24B is a mid-size dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, putting it squarely in the middle of the class on the size lever that drives most of the cost.
- Place-setting capacity. Place-setting capacity is the main driver of how much water a cycle has to heat, and heating that water is most of a dishwasher's electricity use.
- Water heating. Most dishwashers have a booster heater that raises incoming water to sanitizing temperature; this heating step, not the pump or motor, accounts for most of a cycle's electricity use.
- Cycle length and drying method. Heavy or sanitize cycles run longer and hotter than a normal or eco cycle, and heated-dry options cost more to run than air-dry or condensation drying.
Common questions
Is the Summit ADADW24B cheap to run?
Yes. Its $43/yr running cost puts it at rank #174 of 709, below what most dishwasher models we track cost to run.
How much does the Summit ADADW24B cost per month?
About $3.62 a month, which is the $43 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 234 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $43 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Summit ADADW24B for its size?
77th percentile once size is factored in, a fairly typical result for the class.
