Model
Kitchenaid KDTF324PPA
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 Kitchenaid KDTF324PPA cost to run per year?
Do the math and the Kitchenaid KDTF324PPA'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. Normalized for capacity, it beats only 35% of dishwasher models we track, a below-average efficiency result. 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 Kitchenaid KDPS424S*** at $45/yr runs a little cheaper and the Kitchenaid KDTF924PPA 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 Kitchenaid KDTF324PPA's $45/yr adds up to roughly $405 in electricity alone, before purchase price or repairs.

By the numbers
The Kitchenaid KDTF324PPA 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 Kitchenaid KDTF324PPA adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Kitchenaid KDTF324PPA 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 Kitchenaid KDTF324PPA 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 Kitchenaid KDTF324PPA uses 21.8% less energy.
What drives its running cost
At 12 place settings, the Kitchenaid KDTF324PPA 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. 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 Kitchenaid KDTF324PPA 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.
