Model
Danby DDW2400EW
Rank #312 means 311 of the 709 dishwasher models we track cost less to run each year; the 67th efficiency percentile means it uses less energy for its size than 67% of those models.
What does the Danby DDW2400EW cost to run per year?
The Danby DDW2400EW costs about $44 a year to run, a middle-of-the-pack figure at rank #312 of 709. 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. Its 67th size-adjusted efficiency percentile is a step ahead of the class median, though not among the very top results. At 15 place settings, it is a mid-size 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 Danby DDW2400ESS at $44/yr runs a little cheaper and the Equator BB 1840 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 DDW2400EW's $44/yr adds up to roughly $396 in electricity alone, before purchase price or repairs.

By the numbers
The Danby DDW2400EW 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 DDW2400EW 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 DDW2400EW 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 DDW2400EW 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 DDW2400EW uses 22.1% less energy.
What drives its running cost
At 15 place settings, the Danby DDW2400EW 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. 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 Danby DDW2400EW cheap to run?
It is about average. At $44 a year it ranks #312 of 709 dishwasher models we track, close to the middle of its class on running cost.
How much does the Danby DDW2400EW cost per month?
Roughly $3.7/mo, spreading the $44/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 239 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $44 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Danby DDW2400EW for its size?
67th percentile once size is factored in, a fairly typical result for the class.
