Model
Kitchenaid KDTF924PPA
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 KDTF924PPA cost to run per year?
The Kitchenaid KDTF924PPA costs about $45 a year to run, a middle-of-the-pack figure at rank #373 of 709. 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. Its 35th size-adjusted efficiency percentile is a step behind the class median, though not among the weakest results. 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 KDTF324PPA at $45/yr runs a little cheaper and the Kitchenaid KDTF924PPS 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 KDTF924PPA's $45/yr adds up to roughly $405 in electricity alone, before purchase price or repairs.

By the numbers
The Kitchenaid KDTF924PPA 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 KDTF924PPA 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 KDTF924PPA 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 KDTF924PPA 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 KDTF924PPA uses 21.8% less energy.
What drives its running cost
At 12 place settings, the Kitchenaid KDTF924PPA 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 Kitchenaid KDTF924PPA 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 Kitchenaid KDTF924PPA cost per month?
