Model
Jennair JDAF5924RM
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 Jennair JDAF5924RM cost to run per year?
The Jennair JDAF5924RM 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. Once capacity is factored in, its efficiency percentile of 35 is below the class median, worth weighing alongside the raw dollar figure. 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 Jennair JDAF5924RL at $45/yr runs a little cheaper and the Jennair JDAF5924RX 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 Jennair JDAF5924RM's $45/yr adds up to roughly $405 in electricity alone, before purchase price or repairs.

By the numbers
The Jennair JDAF5924RM 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 Jennair JDAF5924RM adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Jennair JDAF5924RM 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 Jennair JDAF5924RM 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 Jennair JDAF5924RM uses 21.8% less energy.
What drives its running cost
At 12 place settings, the Jennair JDAF5924RM 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 Jennair JDAF5924RM 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 Jennair JDAF5924RM 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 Jennair JDAF5924RM for its size?
35th percentile once size is factored in, a fairly typical result for the class.
