Model
Kitchenaid KDTF924PPS
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 KDTF924PPS cost to run per year?
Ranking #373 of 709, the Kitchenaid KDTF924PPS runs at roughly $45 a year, neither the cheapest nor the priciest in its class. 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 Kitchenaid KDTF924PPA at $45/yr runs a little cheaper and the Kitchenaid KDTM405P*** 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 KDTF924PPS's $45/yr adds up to roughly $405 in electricity alone, before purchase price or repairs.

By the numbers
The Kitchenaid KDTF924PPS 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 KDTF924PPS 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 KDTF924PPS 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 KDTF924PPS 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 KDTF924PPS uses 21.8% less energy.
What drives its running cost
At 12 place settings, the Kitchenaid KDTF924PPS 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 KDTF924PPS 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 KDTF924PPS 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 Kitchenaid KDTF924PPS for its size?
35th percentile once size is factored in, a fairly typical result for the class.
