Model
Cafe CDT84***N***
Rank #373 means 372 of the 709 dishwasher models we track cost less to run each year; the 35th efficiency percentile means it uses less energy for its size than 35% of those models.
What does the Cafe CDT84***N*** cost to run per year?
Do the math and the Cafe CDT84***N***'s $45/yr puts it at rank #373 of 709, right around the class average. It uses 21.8% less energy than the U.S. federal standard model in its class, which would cost about $57/yr to run, a saving of roughly $12 a year. Adjusted for size, it is only more efficient than 35% of dishwasher models we track, so part of its running cost comes from its capacity rather than efficiency alone. At 12 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 Cafe CDT828**V*** at $45/yr runs a little cheaper and the Cafe CDT858**V*** at $45/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 Cafe CDT84***N***'s $45/yr adds up to roughly $405 in electricity alone, before purchase price or repairs.

By the numbers
The Cafe CDT84***N*** 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 $45/yr, here is what the Cafe CDT84***N*** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Cafe CDT84***N*** costs about $450. That is roughly $120 less than a standard model in its class, which would run closer to $570 over the same ten years.
How the Cafe CDT84***N*** compares
The dishwasher class we track runs from $15 to $45 a year. At $45/yr, it runs about $1 a year above the class median of $44, and it is about $30 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 Cafe CDT84***N*** uses 21.8% less energy.
What drives its running cost
At 12 place settings, the Cafe CDT84***N*** is a small dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is.
- 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 Cafe CDT84***N*** cheap to run?
It is about average. At $45 a year it ranks #373 of 709 dishwasher models we track, close to the middle of its class on running cost.
How much does the Cafe CDT84***N*** cost per month?
Roughly $3.71/mo, spreading the $45/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 240 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $45 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Cafe CDT84***N*** for its size?
35th percentile once size is factored in, a fairly typical result for the class.
