Model
Danby DDW2400ESS
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 DDW2400ESS cost to run per year?
The Danby DDW2400ESS costs about $44 a year to run, a fairly typical figure for the class; it ranks #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. Capacity-normalized, it ranks ahead of 67% 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 Danby DDW18D1EW at $44/yr runs a little cheaper and the Danby DDW2400EW 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 DDW2400ESS's $44/yr adds up to roughly $396 in electricity alone, before purchase price or repairs.

By the numbers
The Danby DDW2400ESS 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 DDW2400ESS 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 DDW2400ESS 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 DDW2400ESS 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 DDW2400ESS uses 22.1% less energy.
What drives its running cost
At 15 place settings, the Danby DDW2400ESS 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 Danby DDW2400ESS cheap to run?
Roughly, yes. Its $44/yr figure is close to the class median, ranking #312 of 709, neither a bargain nor a splurge on running cost.
How much does the Danby DDW2400ESS 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 DDW2400ESS for its size?
67th percentile once size is factored in, a fairly typical result for the class.
