Model
Danby DDW18D1EB
Rank #311 means 310 of the 709 dishwasher models we track cost less to run each year; the 18th efficiency percentile means it uses less energy for its size than 18% of those models.
What does the Danby DDW18D1EB cost to run per year?
The Danby DDW18D1EB holds rank #311 of 709 on running cost, at about $44 a year, an unremarkable but typical figure for the class. It uses 22.1% less energy than the U.S. federal standard model in its class, which would cost about $57/yr to run, a saving of roughly $13 a year. Efficiency-wise, once size is accounted for, it lags most of the class, ahead of only 18% of the models we track. This class has no published efficiency-factor figure beyond annual kWh itself, so at 10 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 Bosch SHV4AEB** at $44/yr runs a little cheaper and the Danby DDW18D1ESS at $44/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 Danby DDW18D1EB's $44/yr adds up to roughly $396 in electricity alone, before purchase price or repairs.

By the numbers
The Danby DDW18D1EB 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 $44/yr, here is what the Danby DDW18D1EB adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Danby DDW18D1EB costs about $440. That is roughly $130 less than a standard model in its class, which would run closer to $570 over the same ten years.
How the Danby DDW18D1EB compares
The dishwasher class we track runs from $15 to $45 a year. At $44/yr, it sits right on the class median of $44, and it is about $29 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 Danby DDW18D1EB uses 22.1% less energy.
What drives its running cost
At 10 place settings, the Danby DDW18D1EB 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. 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 Danby DDW18D1EB cheap to run?
Roughly, yes. Its $44/yr figure is close to the class median, ranking #311 of 709, neither a bargain nor a splurge on running cost.
How much does the Danby DDW18D1EB cost per month?
About $3.7 a month, which is the $44 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: 239 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $44 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Danby DDW18D1EB for its size?
18th percentile once size is factored in, a fairly typical result for the class.
